Commander Jonathan Ford

Template:Infobox character

Early life

Ford comes from a very financially well off family, his father owning "Ford Freeport: Aquacultural Engineering", one of the largest undersea farming companies in the world. He had a bad relationship with his father and brother. In 2022, an undersea mining operation generated a dramatic rise in the temperature of the South Atlantic. A deinosuchus (gigantic prehistoric crocodile) thawed out and was threatening the local ecosystem and the lives of the local people. With the help of his family, Jonathan stopped the creature. With the lives of the local people at stake, the Fords were forced to settle their differences and reconcile. Ford's father decided to take a year off from work and give Jonathan's younger brother Ben the run of the company.[1] His mother is deceased.[2]

Appointment to seaQuest

Part of the original seaQuestTemplate:'s crew under Captain Marilyn Stark (2015-2017), Ford was forced to relieve her of command when she disobeyed orders and attempted to attack several other submarines after being ordered to stand down. For 13 months after this incident Commander Ford oversaw a major refit of the seaQuest to have the ship generally geared more towards scientific exploration/research and peacekeeping missions. In 2018, after the refit was complete, Admiral William Noyce was trying to convince retired Captain Nathan Bridger, the subs original designer, to take command and ordered Ford to act arrogant, cowardly and generally unfit for command in an effort to get Bridger to stay on board. Despite the ploy not working Bridger decided to stay on board after defeating Stark during her attempt at revenge.[3]

Early on he was in continual conflict with Dr. Kristin Westphalen, the ship's Chief Medical Officer and head of the science department. After the discovery of the Great Library of Alexandria, in which Ford helped with the Excavation (he being the one who accidentally found it), he became much more interested in seaQuest's exploration and research mission and not just the military and peacekeeping aspect.[4] The character had a romance with Lonnie Henderson in the show's third season, although this fizzled out after Henderson had to shoot someone she used to love in order to save Ford.[4]


Commander Ford was portrayed by actor Don Franklin and is one of three actors to remain with the show for all three seasons. Ford appears in every episode except for "And Everything Nice." The character of Ford was originally supposed to have a far different background, originally having him been a poor kid from Chicago who joined the navy to get away from his gang life after witnessing the death of his older brother.[5] Since this was never established in the first year (except for the novelization of the pilot episode and non canon sources such as the others novels and an issue of the comic) it was disregarded for the rest of the series.

Lieutenant Commander Katherine Hitchcock

Template:Infobox character

Lieutenant Commander Katherine Hitchcock was the Chief Engineer of the seaQuest DSV 4600 following her refit in 2018.

While at the naval academy, she, along with Benjamin Krieg, were top of their class, and were eventually wed. However, the marriage only lasted a year.

Being Chief Engineer, Hitchcock was also third in command aboard the seaQuest and was placed in command in several occasions, such as the Liberté space station incident where Commander Ford had been infected with an unknown virus and was unable to perform his duties.[6]

On a mission to save a family from the clutches of an outlaw at the Broken Ridge mining facility, Hitchcock masqueraded as a singer in order to gain access to the mine and allow the family to board the seaQuest.[7]

During an experiment that involved the flooding of the boat, Hitchcock, Ford, Lucas, Krieg, and Chief Crocker were attacked by environmental radicals who intended to use the ship's computer to disable various pollutant manufacturers around the globe. Hitchcock was held prisoner on the bridge along with Lucas where she began to gain their trust by telling them nothing but the truth (under the orders of Commander Ford), although, their leader ultimately believed she would lie to him. She fulfilled her orders by telling the leader that if he attempted to leave the seaQuest as it was sinking, the water pressure would crush his submersible. He didn't believe her and ultimately died.[8]

She and Lucas later developed a prototype for a single-seat submersible that featured perfect laminar flow that replicated the tail of a fish in order to cut down on turbulence. Hitchcock had wanted to name it the Gazelle, though Lucas insisted on the Stinger. Ultimately, the name Stinger became official.[9]

As the seaQuestTemplate:'s tour of duty came to an end, both she and Commander Ford were offered command of the H.R. Clinton, though, the UEO offered her more money to take command than Ford. With the destruction of the seaQuest shortly afterwards, Hitchcock agreed to take command and did not come aboard the new seaQuest in 2021.[10]


Hitchcock was portrayed by actress Stacy Haiduk and appears only in the first season of the series. Haiduk, unhappy with her character's development in the first season, opted not to return to the series for the second season. Her character was replaced by Kathy Evison's character, Lonnie Henderson. Template:-

Lieutenant Benjamin Krieg

Template:Infobox character

Lieutenant Benjamin Krieg served as seaQuest`s procurement officer. He had previously attended the naval academy with Captain Bridger's son Robert and with Katherine Hitchcock, whom he was later wed to for a year. While at the academy, he painted the homecoming mule pink, something that Captain Bridger later found amusing. Krieg had aspirations of a command at sea, but, he never was able to fulfill that dream. Krieg was involved in a few minor transgressions during his tour of duty, such as attempting to extort an Arctic research outpost by selling them thermal underwear at an inflated price, as well as sneaking two-pounds of outlawed ground beef aboard the boat with the intention of making a real cheeseburger. When seaQuest finished its tour of duty and was summarily lost at sea, Krieg resigned from the navy and originally applied to become manager of a fast food franchise, though he tried to convince his fellow crew members he was either going to join the seminary or go to med school.

After the seaQuest-II was lost at sea, Krieg believed that all his old friends were dead. He attempted to run for the Presidency of the United States on an "Eat Peace" platform, but, apparently not many understood what that meant. By 2032, he had apparently relocated to Australia when it became the heart of the Macronesian Alliance. He attempted to lead a group of refugees to safety. Larry Deon gave them a large floating iceberg as their sanctuary. Little did they know that Deon had merely put them there to prevent seaQuest from destroying it. Deon did not count on the fact that Krieg, a former member of the seaQuest crew, would be convinced by Lucas Wolenczak, one of Krieg's closest friends aboard the boat, to be led to safety. Initially skeptical, though eventually pleased, to find that his old seaQuest crew mates were still alive after ten years, Krieg was given a fresh seaQuest uniform upon his return to the ship. Lucas asked him to stay aboard, but, Krieg refused, claiming while seaQuest had to save the world, he had to try and change it.


Krieg was portrayed by actor John D'Aquino and appears in the first season of the series as a main character, and a guest appearance in the third season. D'Aquino, along with Royce D. Applegate was fired at the end of the first season in order to give the next season a "Younger, sexier feel". His character was somewhat replaced by Michael DeLuise's character, Tony Piccolo. Template:-

Lieutenant JG Tim O'Neill

Template:Infobox character Lieutenant JG Tim O'Neill was the communications officer of the seaQuest DSV 4600, originally serving under Captain Marilyn Stark. He remained aboard the boat after she had been relieved of duty and the seaQuest was refitted to serve as more of a research vessel.

O'Neill specialized in foreign languages, was fluent in at least a dozen and could adequately speak several others. He also shared some sort of unknown psychic link with Darwin which allowed him to sense when Darwin was ill.[11]

A religious man since childhood, O'Neill was taught to believe that evolution topped out with mankind and had a difficult time believing in intelligent life on other planets, although, secretly wished that it existed.[12]

He briefly pursued a relationship with Lieutenant Lonnie Henderson in 2021, although, he was uncomfortable with the notion of a shipboard romance and decided not to continue with it, although, the two remained friends.

Somewhat of a nervous individual, O'Neill was prone to occasional acts of heroism, such as fearlessly rushing to save Henderson from the clutches of an alien predator that had invaded seaQuest in 2022.[13] He also questioned the direction his career was headed that year and tendered his resignation to Captain Bridger, though, Bridger assured him that the crew saw him as a valuable commodity, and decided to stay.

Ten years after the Hyperion Incident and the seaQuest`s return to Earth, O'Neill decided to remain aboard the boat under the command of Captain Hudson. O'Neill ran afoul of Hudson on several occasions, such as not responding to orders quickly enough during an emergency situation[14] and questioning Hudson's orders to fire on Captain Bridger's fleet.[15] O'Neill nearly ended his career by stealing a seaLaunch to rendezvous with his on-line girlfriend while in the middle of an unstable political area. However, his girlfriend, Heiko Kimura, turned out to be a defector from the Chaodai. He once again disobeyed orders by refusing to deliver Kimura into their hands, however, his actions ultimately saved both Kimura and the seaQuest, prompting Lucas Wolenczak to suggest that he may be in line for a promotion.


O'Neill was portrayed by actor Ted Raimi and was one of three actors to remain with the series for entire duration. The Character of O'Niell was originally supposed to be a character named Garry Stephen Bachmann from Ottawa, Canada. This was then changed to be a woman named MacKenna O'Neill, then the character was changed back to a male and renamed "Mack O'Neill".[16] This name was used right up until filming was to begin, name tags designed for his uniforms that read "M. O'Neill" are known to exist before it was ultimately changed to "Tim."[17] This is also why his name was Mac in the comic and Stephen Bachmann in the non canon novels. Template:-

Senior Chief Petty Officer Manilow Crocker

Template:Infobox character

SrCPO Manilow Crocker was on the brink of retirement when Admiral Noyce personally asked him to sign aboard seaQuest when it was put back to sea in 2018. Crocker had served together with Captain Bridger before and, as a result, did not regret his decision to serve one more tour with his old friend.

As Chief of Security aboard seaQuest, Crocker was responsible for the safety of all aboard. On more than one occasion, he was ordered to board enemy vessels and colonies to take the occupants into custody. Crocker was also the first Human being to lay eyes on an actual alien when the seaQuest found an ancient alien starship entombed in an underwater rock face. The alien fired at Crocker, but, it was merely a method of transportation which moved Crocker to a holding area aboard the alien ship, before finally returning him to seaQuest.

As seaQuest`s tour ended, Crocker was finally able to retire and had secured a civilian job as head of security for Tucker Enterprises. Unfortunately, Crocker's wife Helen, informed him via a video message that she had fallen in love with another man, devastating the Chief. With his personal life in ruin, Crocker volunteered to a dangerous mission to take a seaLaunch to the World Power facility that was engulfed in an exposed lava flow in the hopes of finding Dr. Lawrence Wolenczak and possibly a solution to the problem. His mission a success, Captain Bridger ordered him to abandon seaQuest with the rest of the crew in order to spare his life.

With seaQuest destroyed in the incident, Crocker firmly believed that there would never be another seaQuest.


Chief Crocker was portrayed by actor Royce D. Applegate. In the second season, Crocker was replaced by Lieutenant James Brody as head of security aboard seaQuest, while Applegate was dismissed from the cast, replaced by Edward Kerr.

Chief Petty Officer Miguel Ortiz

Template:Infobox character

CPO Miguel Ortiz was a member of seaQuestTemplate:'s original crew under Captain Stark. After she was relieved of duty, he stayed on, serving again under Nathan Bridger's command.

As the Head Sensor Operator, Ortiz was responsible for controlling the boat's WSKRs (Wireless Sea Knowledge Retrieval Satellites) and was also involved in various away missions. He could understand Spanish and had a knowledge of Greek mythology, particularly that of Atlantis.

Like Dr. Wendy Smith, it is assumed that Ortiz was killed in action while the crew was trapped on Hyperion.


Marco Sanchez portrayed Ortiz during the first and second season of the show. He requested to remain for the third season, but was ultimately let go after NBC decided to lower the cast number. The character that ultimately became Ortiz underwent 2 radical changes before becoming what it did. First he was a man named Drew and then was changed to being the son of a rich Vietnamese family named Ngyuen Ky before settling on making him Cuban, the name originally being Mundo Ortiz.[16] Template:-


Template:Infobox character

Darwin is a dolphin. He is able to communicate to the crew through the assistance of a translation device known as the vo-corder, and to navigate throughout the seaQuest via a series of water-filled access tunnels leading to the ship's moon pool openings, where he could interact more directly with the rest of the crew.

Nathan Bridger was living on an island before accepting command of the seaQuest when he rescued Darwin from a fishing net. He began working on communicating with and training Darwin, using hand-signals to communicate. The two became close friends, and even in his capacity as captain, Bridger often referred to him as "My dolphin," treating him at times like a very fond pet, and at other times like an equal, even diverting the ship from a research mission in order to seek medical assistance when Darwin became sick, citing that he was a member of the crew just as much as anyone else.

Lucas was also shown to have a particularly close relationship with Darwin after Darwin and Bridger joined the crew, and it was Lucas who developed the vo-corder translation system (based on Bridger's notes) for communicating with Darwin. Lucas once noted that Darwin tended to follow him around, and that they were something of an inseparable pair.

Darwin, being in a unique position, often assisted the crew in key ways, such as planting a homing beacon on another ship, splashing water onto a containment field device when Bridger and Crocker were trapped inside, and various other accomplishments.



Template:Primarysources Template:Reflist

This is an almost complete list of the main characters of seaQuest DSV season 2. The series went through significant cast changes after every season it was on the air. This list contains only those characters that were given credit in the main titles of the second season, therefore it does not contain characters such as Admiral Noyce (which is located at List of recurring characters on seaQuest DSV) or characters who first appeared in the first season such as Commander Jonathan Ford (which is located at Main characters of seaQuest DSV season 1).


Second season main characters

Dr. Wendy Smith

Template:Infobox character

Wendy came aboard the seaQuest DSV 4600 II in 2021 after the first seaQuest had been destroyed by Captain Nathan Bridger the previous year in an attempt to seal a lava pool that threatened to melt the world's polar caps.[10] When Dr. Kristin Westphalen elected not to sign aboard the new seaQuest, Dr. Smith won the most coveted medical position in the UEO that of the chief medical officer of the flagship.

A doctor of all trades, Wendy only took her residency in psychiatry; with a Ph.D in biophysics; although her passion was parapsychology. Discovering that she had a high psi-factor as a child, Wendy found that she could sense the thoughts and emotions of the people around her. Calling it her "sixth sense", she sometimes wished she didn't have the talent, but usually used it to her advantage, although, she swore that she never probed anyone's thoughts without their permission.[18]

Wendy came from a navy family with both her mother and grandmother serving. Captain Bridger had, not only served under her mother, Lexington Fisher-Smith (aka "Sexy-Lexy Smith"), but also pursued a brief romantic involvement with her before ultimately ending the relationship. However, Bridger's prior interest in her mother didn't stop the captain from developing feelings for Wendy. At first, Wendy resisted the relationship and considered transferring off of seaQuest due to the scandal a relationship with the ship's captain would no doubt present, but, after convincing from both Bridger and Lucas Wolenczak, Wendy decided to remain aboard the ship.[19]

Prior to her relationship with Bridger, Wendy had engaged in a relationship with Clay Marshall, director of a parapsychology facility, who helped her develop her telepathic sense, however, the relationship eventually ended. When Tony Piccolo and Dagwood mysteriously shared a nightmare, Wendy took them to be examined by Marshall. However, Clay had been cybernetically augmented in the years following their relationship and required sentium available in the seaQuest's missiles as blood. Desperate to get the material, Marshall used his previous relationship with Smith to help gain access to the seaQuest, however, he was ultimately foiled.

On May 14, 2022, Wendy, along with the rest of the seaQuest crew were transported to the far distant planet Hyperion, tricked into becoming participants in the Hyperion civil war. Wendy was part of the away team sent from seaQuest to destroy the KrayTak mothership and was able to confirm that Tobias LeConte, who had been captured by the KrayTaks, was the genuine article, not a Stormer clone. With the seaQuest hulled by a barrier mine and their shuttle destroyed, the team looked to be doomed. With no other choice, Captain Bridger activated explosive charges and destroyed the mothership, taking the away team with it.[20]

Although the Hyperion rebels were somehow able to save the majority of the seaQuest crew, as well as repair the critical damage to the ship and return them all to Earth, it's assumed that Smith was not able to be saved and ultimately perished on Hyperion though her character is never referred to by name.[21]


Dr. Smith was portrayed by actress Rosalind Allen and was Stephanie Beacham's replacement after she opted not to return for the second season of the show. Allen's character has been a point of criticism from many fans of the show as her character's psychic and telepathic abilities helped to push seaQuest DSV away from reality-based fiction to heavy science-fiction and fantasy.

The character of Dr. Smith was originally two different characters; Diane Page, a 35-year-old African American Ph.D and Wendy Woo, a 25-year-old M.D.. The producers of the show originally wanted Tamara Tunie and Kelly Hu respectively.[22]

Kathy Evison originally auditioned for the role of Dr. Smith. Although she didn't get the role of Dr. Smith, the producers liked her and created a new character, Lonnie Henderson, for her to play.

The episode "Alone", which focused extensively on Dr. Smith's powers, infuriated actor Edward Kerr (Brody) to the point that he stormed off the set and did not appear in the episode.

Allen's character was eventually written out of the series at the end of the second season as the series began to progress back towards more reality based episodes in the third season. Template:Clear

Lieutenant James Brody

Template:Infobox character

When Brody was three years old, his mother was involved in a murder cover-up at the (accidental) hands of Franklin Thomas. Contracting the P-Core A virus, Brody's mother was placed in cryogenic suspension and he was sent to live with his grandparents, who "let (him) get away with murder.[23] After joining the navy, Brody led a stealth invasion during the North Korean Crisis in 2010, which Captain Bridger considered to be a "nifty piece of work."

Assigned to the G.E.L.F. colony prison island, Brody began to sense subtle changes in the behavior of the G.E.L.F.s, finally culminating in their uprising and seizure of the colony. Brody, however, was able to escape and was picked up by the seaQuest, after which the crisis had ended, he joined the crew as tactical officer.[18] As tactical officer, Brody led most away missions into hostile environments and manned the weapons console when Commander Ford was in command.

When Brody's mother awoke from her cryogenic suspension, she sought out her son, who took her aboard the seaQuest to shield her away from assassins plotting to kill her, hired by General Thomas, to protect his career. Ultimately, Brody was able to apprehend Thomas, allowing his mother to return to cryo-stasis, secure in the knowledge that when she awoke again, she would have nothing to fear. He also promised his mother that he would be with her again when she was revived.[23]

When the seaQuest was abducted to the planet Hyperion in 2022, Brody was wounded while part of an away team sent into the Hyperion mothership intent on destroying it. Brody, along with the rest of the away team, were apparently destroyed along with the ship after Captain Bridger detonated an explosive attached to the ship's plasma core, but was able to be rescued by the Hyperion rebels and returned to Earth with the majority of the crew by the year 2032.[20]

Brody butted heads with the seaQuest's new captain, Oliver Hudson, played by Michael Ironside, who apparently favored his personal student, Lieutenant Fredericks, over Brody. However, when President Alexander Bourne and Larry Deon conspired to gain control of Fredericks' psyche-implant, Brody was able to learn the truth and inform Captain Hudson, saving both Fredericks and Secretary General McGath, whom she was being manipulated to assassinate.[24]

At some point in his life, Brody sired a child with a woman. However, being a career-military and a private man, Brody never told any of the seaQuest crew of that aspect of his life. He himself only found out about the then 10-year-old child after the ship returned from Hyperion and the mother of the child decided to contact him after one of her parents had recently died.[25]

Brody ultimately died later that year in a rescue mission to save Lieutenant Henderson from a Macronesian death sentence. His last words were "With your shield or on it."[25]


Brody was played by Edward Kerr and was named after Police Chief Martin Brody (played by Roy Scheider) in Jaws. Brody was Chief Crocker's replacement, both on the show and on the ship (after Royce D. Applegate was released from the show and Chief Crocker retired from the navy). Kerr was not fond with the content of the episode "Alone" and refused to appear in it. Frustrated with the direction of the show and afraid that the series would hurt his career, Kerr requested to exit the show along with Scheider. NBC granted him his release as well, under the provision that he continue to play Brody for a few episodes into the third season so his character could be killed off for dramatic impact.

The two actors originally considered for the role of Brody were Dan Gauthier and Paul Gross.[22] Template:Clear

Warrant Officer Anthony Piccolo

Template:Infobox character Anthony Piccolo first boarded the seaQuest as a Seaman in the episode Daggers, the first seaQuest DSV episode of the Second Season. He was an experimental ex con, let out from prison on an early release program where they conducted science experiments on volunteers. Piccolo was offered and then received a pair of genetically altered gills, allowing him to breathe underwater like a fish. He was put on seaQuest because that's where the parole board thought he would be most useful.

At first he was rebellious, and attempted escape shortly after boarding, but soon was bunked with Lucas Wolenczak, and though they first irritated one another, they soon became friends. Piccolo was originally from New York City and his wise crack Italian humor often relieved tense situations and gained him popularity, though he was often teased light heartedly among the crew. He enjoyed showing off his talents in gambling and playing the piano, and was a big Elvis fan.

He also was dyslexic which caused him to struggle when he decided to apply for the Officer Candidate School, in the third season of seaQuest. Lt Lonnie Henderson, who had already passed the program, tutored him. Although he didn't pass the test Capt. Hudson was impressed with the effort he put into it and promoted him to the rank of Warrant Officer, which let him continue to qualify for Sub Fighter training under Lt. Fredericks.


Tony Piccolo was played by Michael DeLuise. In the first season Lucas had a little brother relationship with Krieg, for this season Lucas became the mentor to Piccolo, and empathized on his family problems since he too came from a broken family. One of Picollos most important aspects, according to Producer Carleton Eastlake, is "he´s also the most human of the whole crew, because he´s really very unsophisticated."[26] DeLuise was on the original short list for the part of Piccolo, along with Max Perlich. Template:Clear

Lieutenant JG Lonnie Henderson

Template:Infobox character

Lieutenant Lenore "Lonnie" Ellen Henderson signed aboard the seaQuest DSV-II as a helmsman in 2021. As a first generation naval officer, she was a bit rough around the edges in terms of proper protocol. She successfully was able to smuggle her stuffed bear Addison aboard seaQuest, much to the consternation of Commander Ford.

Henderson initially showed an interest in Lieutenant O'Neill and the two spent some shore leave together. However, O'Neill was uncomfortable dating someone he served with and the two remained just friends. She also offered herself to Lucas Wolenczak when it was believed that he was going to die in a subterranean cavern. Lonnie was mistaken for Medusa by Neptune, the God of the Sea. She was also captured and possessed by an alien Stormer when it hatched itself aboard the seaQuest. The Stormer attempted to use Henderson's form to get close to Professor Tobias LeConte, but, Tobias was able to see through the alien's ruse and Henderson was set free.

When seaQuest returned to Earth in 2032, she began a romantic relationship with Commander Ford, while simultaneously trying to help Tony Piccolo overcome his dyslexia. This led to jealously between Ford and Piccolo, but, Henderson ultimately chose Ford. In an attempt to save two Spindrift children from Macronesia, Henderson was captured and held prisoner by Macronesia. President Alexander Bourne wanted to use her to humiliate the UEO and allowed her to be put up for execution. She was rescued by a seaQuest team, but, it cost the life of Lieutenant James Brody.

While on a mission to the Tartarus Federation, Henderson became aware that her first lover, Jason Pardee, appeared to be imprisoned there wrongfully. She attempted to help him, but, in the process, accidentally incited a prison revolt that allowed Mason Freeman and Pardee to take a group of researchers at Osiris Base as well as Ensign Wolenczak and her hostage. In the ensuing escape, Henderson was forced to kill her former lover. The incident shook her faith in love and ended her relationship with Commander Ford.


Henderson was portrayed by actress Kathy Evison, who had originally auditioned for the role of Dr. Wendy Smith. While not scoring the role of Dr. Smith, the producers created the role of Henderson for Evison. As a result, her character was not in the first few scripts of season 2 and had to be hastily inserted wherever possible.


Template:Infobox character

Dagwood was the prototype G.E.L.F. He originally did not have a name, yet adopted the name "Dagwood" (a joke), since G.E.L.F.s were also known as "Daggers." Dagwood was the imperfect prototype Dagger, intended as a supersoldier, but reassigned to custodial duties, eventually being placed aboard the new seaQuest DSV in 2021. He proved his worth to the seaQuest crew almost immediately when he saved Lieutenant O'Neill's life by lifting a large turbine which collapsed on top of him. He was also able to convince Mariah, leader of the G.E.L.F. uprising that the G.E.L.F. baby was in fact a human. Dagwood is very useful when it comes to using his great strength. Although he doesn't speak very much and is a slow learner, he is always willing to help the crew on assignments.

Dagwood was convicted of the murder of his creator and sentenced to life imprisonment. As it turned out, the murder had in fact been perpetrated by another G.E.L.F. prototype who looked identical to him. Dagwood was able to destroy his doppelganger and clear his name.

When Captain Hudson assumed command of the seaQuest in 2032, Dagwood had to again prove his worth to the new captain, as Hudson had decreed that there would be no civilians aboard seaQuest. He was able to temporarily stop Ben Krieg's attack on the seaQuest shore party by braving the weapon fire and approaching Krieg personally. Hudson rewarded him with a naval commission and a seaQuest uniform.

Dagwood was part of the infiltration team led by Captain Bridger to the Macronesian outpost on Banaba Island where a UEO scientist had performed crimes against humanity by experimenting and torturing live G.E.L.F.s. Dagwood was outraged, as he had always disbelieved the G.E.L.F. opinion that humans had tortured his people and ultimately destroyed the remaining research.


Dagwood was portrayed by Peter DeLuise. He had previously portrayed the character "Whiggins" in the first season episode "Whale Song".



This is the complete list of Characters of seaQuest 2032, which was the final season of seaQuest DSV. The series went through significant cast changes after every season it was on the air. This list contains only those characters that were introduced in this season (therefore, does not contain characters who first appeared in the first or second season such as Secretary General Arthur McGath (which is located at List of recurring characters on seaQuest DSV) or Commander Jonathan Ford (which is located at Main characters of seaQuest DSV season 1)).


Third season main characters

Captain Oliver Hudson

Template:Infobox character Captain Oliver Hudson was the third commanding officer of the seaQuest after Captain Marilyn Stark and Captain Nathan Bridger. Hudson assumed command of the boat in 2032. After the seaQuest mysteriously disappeared off the face of the Earth in 2022, Hudson began a ten-year search for the missing ship and crew while in command of a slow-moving, long-distance hauler, which he believed would give him the best chance of finding it.[27]

Following the rise of the Alliance of Macronesia, Hudson considered retirement, however, the UEO offered him triple the pay and command of any boat he wanted. Unfortunately, the only boat he really wanted to command was seaQuest, but, it was still missing. Nevertheless, the UEO ordered the transfer of command of seaQuest from Bridger to Hudson should the boat ever be discovered intact. In the meantime, due to the rising escalation of hostility between the UEO and Macronesia, Hudson diverted much of his attention to slowing the expansion of power and territory of the Macronesian President, Alexander Borune. Hudson studied his enemy in Bourne and knew of both his public and personal life.

When seaQuest was discovered in an Iowa cornfield in 2032, the transfer of command took place and Hudson took his place on the bridge of the ship. Initially, Hudson butted heads with many crewmembers, first being Lucas Wolenczak, who was forced to enlist in the UEO navy in order to stay on seaQuest. Wolenczak, however, was able to impress Hudson over the course of his duty by being a competent and reliable science officer. Commander Ford was next to clash with Hudson, however, it was soon realized that Hudson was simply testing Ford to see how well his new executive officer could perform his duty. Hudson also positively affected the lives of Tony Piccolo and Dagwood, both of whom sought to advance their careers in the UEO. Hudson took a shine to Piccolo in particular, by ordering him to read his copy of The Red Badge of Courage in order to, not only learn about duty and honor, but, also to help him overcome his dyslexia. As a result, Piccolo soon trained to be a sub-fighter pilot as well as studying to be a lieutenant. Lieutenant J.J. Fredericks, who joined seaQuest along with Hudson, was also considered by the captain to be "his best student."[28]

However, while Hudson may have positively affected several crewmembers, he was not overly fond of Lieutenant JG Tim O'Neill, who believed Hudson treated him like a child. During an attack on seaQuest's sub-fighters, Hudson physically manhandled O'Neill out of his station when he could not deliver a speedy and efficient answer to Hudson's questions during a crisis.[28] Nevertheless, while Hudson may have found some of O'Neill's choices questionable, he still relied on his extensive knowledge of languages on the bridge.[29]


Hudson was portrayed by actor Michael Ironside and replaced Roy Scheider as the star of the series after Scheider left the series at the end of season two. Hudson appeared in all thirteen episodes of the third and final season. The producers wanted a character different from Bridger, so instead of being the relaxed fatherly figure Hudson had more of a Military personality. Using some unused aspects from Bridgers original character profile in the season 1 writers bible Hudson enlisted in the US Navy as a way of rebelling against his father, the only onscreen evidence of this was an enlisted Good Conduct Medal on his ribbon bar.[30] The aspects concerning his father would have been dealt with had the series not ended, in what would have been the 15th episode of the season, "Depths of Deceit".[31] The reception Hudson received was mixed. Template:Clear

Lieutenant J.J. Fredericks

Template:Infobox character

Lieutenant J.J. Fredericks ("Freddie") had served with Captain Hudson aboard the hauler he commanded prior to both of them signing aboard seaQuest. Hudson considered her his best student and believed that she dedicated her whole life to her duty. While training to pilot a Spectre-Demon class subfighter, Fredericks accidentally crashed it, almost drowning in the process. She became extremely fearful of ever piloting it again and since the UEO had invested so much in her training, they convinced her to wear a "psyche-implant"; a device that literally "programmed the scare out of her." The device also gave the UEO 24 hour access to every feeling that she had, but, she was willing to deal with the inherent humiliation in order to become the best subfighter pilot in the UEO. Unfortunately, Larry Deon and President Alexander Bourne were able to gain access to her psyche-implant and reprogrammed it to coerce her to assassinate UEO Secretary General McGath. Thanks to the efforts of Lieutenant Brody and Ensign Wolenczak, Fredericks was able to fight against their programming and McGath's life was saved.

Fredericks had a hand in the subfighter training of Lieutenant Brody and Warrant Officer Piccolo. Unfortunately, during an engagement with a squadron of Chaodai subfighters, Fredericks lost her life when she was fired upon and destroyed. Captain Hudson was deeply affected by her lost and angrily objected when it was suggested that the defecting Lt. Commander Heiko Kimura, formerly of the Chaodai Nation, replace Fredericks aboard seaQuest. However, Secretary General McGath made it an order. Hudson took it upon himself to clean out Fredericks' quarters.


Lieutenant Fredericks was portrayed by actress Elise Neal and appeared in eleven of the thirteen season three episodes. Despite the cancellation of the series, Fredericks was always intended to die in "Weapons of War", as the unproduced episode following it, "In Father's Footsteps", features the character of Kimura. Her first name was not mentioned during her tenure on the show, just the initials "J.J." are visible on her uniform and on her quarters.

Third season recurring characters

Dr. Perry

Template:Infobox character When seaQuest returned to Earth in 2032 after mysteriously disappearing ten years earlier, Dr. Wendy Smith was among the casualties suffered in the Hyperion Civil War the seaQuest was forced into in 2022. With no chief medical officer, Dr. Perry signed aboard the ship as Smith's replacement.[28]

During her time on the ship she performed several important tasks that save countless lives. Dr. Perry and Lucas were able to synthesize a cure for a mutated viral strain that threatened the crew of seaQuest.[32] When the ship was thrown back in time to October 1962, Perry attempted to treat a man who had suffered extreme radiation poisoning from nuclear fallout. Unfortunately, the man was so highly radiated that she could not even hold his hand as he died.[33]


Dr. Perry was portrayed by actress Karen Fraction. With the shows shift to more military based story lines the networks desire to reduce the number of main characters the part of Dr. Perry, who was in 8 out of the 13 episodes of the final season, was only credited as a recurring character. Like J.J. Fredericks her first name is unknown. While her rank was never stated, she wore a scientific-style uniform similar to Dr. Westphalen in the first season, unlike Dr. Smith, who never wore a uniform. Template:Clear

Lt. Commander Heiko Kimura

Template:Infobox character A Chaodai sub fighter pilot that defected to the UEO in 2032 to warn them of the future threat posed by the Chaodai.

She conducted an online relationship with Lt. O'Neill and used him to find the ship and get on board. When Tim confronted her about it later she told him that she didn't feel bad about tricking him, because the Chaodai represented a horror he couldn't imagine, and that he should have been glad to have his fantasy girl for as long as he did. She was willing to give herself up to save the seaQuest when the rest of her squadron tracked her down but she was saved (against her will) by O'Neill, who sent her ship out on autopilot, where the remaining ships immediately destroyed it. When she tried to thank him he was still quite angry and told her he was only doing his duty.[29]


Lt. Commander Kimura was portrayed by actress Julia Nickson. Although only appearing in the final episode, Lt. Commander Kimura would have replaced Lieutenant J.J. Fredericks as the head of the sub fighter pilots assigned to seaQuest, and was scripted to appear in the next, unfilmed seaQuest episode "In Father's Footsteps".

President Alexander Bourne

Template:Infobox character President of the Macronesian Alliance (formerly New Australia), Bourne rose to power during the ten years that seaQuest was missing. The ships in his naval fleet, the Lysander class, were capable of subduction; particle liquefication, which "turns land mass into soup" and allowed him to seize power in half of the Pacific Ocean. Bourne did not agree with the policies and limitations of the UEO and sought any means to discredit and defame them. As a result, and because of several concerns about human rights violations, the UEO imposed a trade embargo against Macronesia, which led to several conflicts between both governments. Many in the UEO believed that it would take a miracle to stop Bourne's rise in power, territory, and influence. When seaQuest seemed to reappear shortly thereafter, they were able to stop Bourne's attempt to annex the Nexus Colony that would have given him access to remainder of the Pacific Ocean, as well as the lives and freedom of hundreds of thousands of people.[28]

When the UEO constitution was up for renewal, Bourne moved to dissolve the UEO. However, without assurance of victory, he conspired with Larry Deon and a Dr. Slaussen to gain control of Lieutenant J.J. Fredericks, a seaQuest crew member's, psyche-implant, which would place her mind under their control. With her to do their bidding, they programmed her to assassinate Secretary General McGath, which would cripple the UEO beyond repair. However, Fredericks was able to resist their mind control and Bourne's plans were thwarted.[34]

When Lieutenant Lonnie Henderson, another seaQuest crewmember, was caught in Macronesian waters attempting to rescue a sinking ship with children aboard (that had been fired on by Macronesian forces), Bourne attempted to use her to humiliate the UEO by breaking her in prison and executing her before the world audience on the trumped-up charge of kidnapping the children she was rescuing. Again, Bourne's plans were ruined by a seaQuest away team who were able to break her free from her cell and return her safely back to the ship.[35]


President Bourne was portrayed by actor Michael York.

General Armand Stassi

Template:Infobox character Alexander Bourne's right-hand man and the Highest Ranking officer in the Macronesian Military. He was with the President in the attempted take over of the Nexus Colony, which was ultimately thwarted thanks to the return of seaQuest and the help of Nathan Bridger.[28]

In "Chains of Command" a Mad UEO Admiral named Van Alden tried to start a war with the Macronesian Alliance by destroying a Mac submarine rearmament base. The UEO covered up the event and said it was a robot instillation that malfunctioned, since the base was a classified first strike facility located deep in Macronesian territory and sent in Captain Hudson to deal with the situation. Since the Alliance didn't know about the base when they decided to back-track the missile it led to seaQuest, since it was close to the base, since it had orders to destroy the base if Hudson failed. Stassi, believing them responsible for the bases destruction, ordered an attack against seaQuest, although it ultimately evaded the subs and destroyed the base.[36]

When Lonnie Henderson, a seaQuest crewmember, was caught in Macronesian waters attempting to rescue a sinking ship with children aboard, Stassi (who was aboard one of the attacking ships) charged her with kidnapping the children she was rescuing and smuggling. Ultimately Captain Hudson rescued Henderson, although the rescue cost L.t. Brody his life.[34]


General Armand Stassi was portrayed by actor Andrew Stahl. In an unfilmed script, that likely would have been produced had the show not been canceled, Stassi would have been shot after a failed assassination attempt against President Bourne. Stassi was usually shown as being mostly as a patriot, more interested in the good of the Alliance than anything, whereas Bourne was more concerned with his own power and wealth.

Larry Deon

Template:Infobox character A business tycoon who served as chairman of Deon International, the largest supplier of most of the world's goods and resources. Deon International also operated restaurant chains, military development groups, and major sports franchises, such as the "Deon Demons." Deon, who "sold IBM off at a yard sale when he was 24", sought to conglomerate his empire with the entire world market, making Deon International "the only game in town." As manufacturer of the, allegedly, state of the art Lysander-class subfigher (high speed submersibles capable of engagements at speeds up to 300 knots), Deon International was able to neatly furnish Macronesia with their underwater war machines.

When Deon International's underwater manufacturing raised ocean temperatures causing an iceberg the size of New England to shear off a glacier in the Weddell Sea, Larry placed a group of Macronesian refugees on the iceberg in order to prevent seaQuest from destroying it. If left untouched, the iceberg would have impacted the Saudi Desert, which when melted, would flood the desert, allowing Deon International to purify the run-off and corner the market on the world's first fresh water supply. However, Larry failed to realize that a former member of the ‘'seaQuest’’ crew, Lieutenant Ben Krieg, was leading the refugees. Lucas was able to convince Krieg to order his followers off the iceberg and onto ‘‘seaQuest’’ that could then safely destroy the iceberg.[28]

A major player in the airplane business as well, Deon International attempted to sabotage the revolutionary "OmniPacific", an underwater train that would have drawn business away from Deon's airports. However, thanks to Lucas' efforts, the train was safely brought to a halt and the passengers remained uninjured.[37]

Larry would soon conspire with President Bourne's attempt to assassinate Secretary General McGath in order to abolish the UEO. Captain Hudson was able to stop him and planned to bring him to justice, but before he could say anything, Mason Freeman, Deon's right-hand man, shot him to prevent Larry from incriminating himself or the company. While he was seriously injured, Deon was not killed. He remained in a coma.[35]

Mason Freeman

Template:Infobox character Larry Deon's right-hand man, Freeman is more aggressive, ruthless, and in many ways, more cunning than his boss is. Larry ordered him to capture Captain Hudson and hold him hostage to further ensure that an iceberg in the Weddell Sea would not be destroyed by seaQuest. Hudson was able to overpower Freeman, but rather than send him to a UEO prison, he ordered Freeman sent back to Deon, to tell Larry that while he sent his best man, Hudson sent him right back.[28]

Mason was later sent to sabotage the OmniPacific underwater train in order to keep Deon International's air travel services number one in long-distance traveling. Mason's efforts were thorough, but Lucas was able to safely stop the train and save the passengers. Freeman, however, was able to escape.[28]

Apparently not on speaking terms with Larry, Freeman shot his boss after Captain Hudson had arrested him, in order to stop Larry from incriminating Deon International in the plot to assassinate Secretary General McGath. Freeman was immediately arrested and imprisoned.[35]

Freeman, and Jason Pardee, a former love of Lieutenant Henderson, were able to escape prison and held a science team hostage in exchange for their own freedom. Freeman was also able to take Lucas and Henderson prisoner after they were sent over to the science station under the pretense of assistance. Plotting to kill Lucas to send a message to Captain Hudson, Henderson, Lucas, and the science team were able to escape. While Jason Pardee was killed at the hands of Henderson, Freeman seemed to disappear. As the seaQuest futilely tries to find him, he happily rolls along the ocean floor in an underwater tank, singing to himself in contentment.[38]


Mason Freeman was portrayed by actor Ralph Wilcox. He had previously appeared in the season two episode "When We Dead Awaken" as a hired killer who tried to kill Alison Brody, the mother of Lieutenant James Brody. Whether or not they were intended to be the same character was never stated, although they had a similar attitude/personality.



This is a list of the recurring characters featured on the television series seaQuest DSV. This list does not include characters listed in the main titles of the show or characters introduced in seaQuest 2032. (Those can be located at Characters of seaQuest 2032.)

UEO Personnel

Admiral/Secretary General William Noyce

Ranked as admiral in the UEO navy, Noyce had served with Captain Bridger for many years prior to his appointment to seaQuest. Noyce was usually seaQuest`s liaison to UEO Headquarters and often relayed mission orders and other commands to the ship. Noyce had met future UEO secretary general Andrea Dre at Woodstock when his own car broke down. They remained friends for years afterwards. However, when Dre had plotted to assassinate the leaders of the various UEO confederations, Noyce had her arrested, impeached, and eventually, was appointed as acting secretary general. Originally stationed at the UEO naval base at Pearl Harbor, Noyce eventually transferred to New Cape Quest when UEO Headquarters was relocated there in 2021.

Admiral Noyce was portrayed by actor Richard Herd.

Secretary General Arthur McGath

Replacing William Noyce as the Secretary General of the UEO, McGath was frequently in contact with the seaQuest to issue new orders and missions. Possessing a high amount of respect for Captain Bridger, McGath refused to relieve him of command when a gold helmet believed to be from Atlantis cursed Bridger and caused him to behave irrationally, claiming he did not want the last thing on the captain's record to read "relieved of command by the Secretary General."

By 2032, McGath was still Secretary General as the UEO faced the threat of the expanding Macronesian Alliance under the leadership of President Alexander Bourne. When Captain Oliver Hudson assume command of seaQuest, McGath often found himself at odds with him, however, believed that he was a very capable ship captain. When the UEO constitution came up for renewal later that year, Hudson informed McGath that half of the people in the world believed him to run the UEO like a police state and the other half believed him to be "a big wimp". President Bourne and Larry Deon had attempted to assassinate McGath, however, their plans were foiled, the UEO constitution was renewed and he remained Secretary General.

Secretary General McGath was portrayed by actor Michael Costello. He was not given a first name during the series, but, the unproduced episode "Depths of Deceit" name him as "Arthur."

General Francis "Frank" Gideon Thomas

A General seen in the US Army in 2019, then in the UEO Army as of 2021. Thomas was involved in a murder cover-up in his early adulthood involving Alison Brody resulting in the death of her friend. Realizing that she would be able to testify against him, Thomas conspired with a corrupt doctor to infect her with a fatal virus so that she wouldn't be able to incriminate him.

In 2010 during the "Korean Crisis", Thomas was captured along with three of his men, but was able to negotiate for his release.

In 2019, Thomas ordered Captain Bridger to destroy the perpetrator who had been sinking whaling ships. When Bridger refused to hunt down someone and kill him, Thomas assured Bridger that if he didn't obey his orders, he would ruin the careers of the seaQuest crew. In 2021, Thomas was captured by a group of G.E.L.F.s who used him to gain access to the Ronald Reagan Memorial Laser Space Base, which they used to destroy the air exchange plants in attempt to suffocate the human race. Fortunately, seaQuest was able to stop them and Thomas was released.

Later that year, when a group of peaceful aliens made first contact with the human race, Thomas plotted to hold them hostage if they did not provide the human race with advanced information and technology, to the point of ordering seaQuest to fire on their ship as it left the planet. The aliens proved to be too quick for him, however. (Although, due to the aliens' technology, time reversed itself and none of these events actually took place in the new timeline.)

Several weeks later, Alison Brody, who had been in cryogenic stasis since her infection, emerged from her sleep. Worried, Thomas had her kidnapped and planned to kill her once and for all. Fortunately, Lieutenant James Brody, her son and member of the seaQuest crew, was able to intercept the general and rescue his mother. Although Thomas' fate is unknown, it can be inferred that he was likely discharged from the military due to his actions and sentenced to prison.

General Thomas was portrayed by actor Jesse Doran.

seaQuest Crewmembers

Chief Carleton

One of the Lead helmsman aboard seaQuest, Carleton came on board after Stark was removed from command but before Bridger assumed command. He was a main fixture on the bridge from 2018 to mid 2019.

He was on duty when the boat was heavily damaged after a lightning bolt struck the ship's communication's buoy. He, along with the bridge crew, was able to reroute power from one of the ship's WSKRs, operate the vessel, and save a downed French submarine. Carleton eventually left the ship and was replaced in 2019 by Chief William Shan.

Carleton was portrayed by actor Dan Hildebrand.

Lieutenant Dalton Phillips

One of the weapons officers aboard the seaQuest, Phillips had served under the command of Captain Marilyn Stark prior to her dismissal as captain of the ship. When Bridger assumed command of the boat, Phillips remained on board.

Friends with Lieutenant O'Neill, Phillips joined him for coffee in the mess hall on occasion. Dubious as to the abilities of Lucas, Phillips was reluctant to allow him access to the weapons console on the bridge until Lieutenant Commander Hitchcock allowed him to.

When Capt. Bridger, Lucas, and was attending a conference Dr. Young was brought aboard when his magma buoy resurfaced. Commander Ford and several other members of the seaQuest crew and a group of civilians were on the island during a volcanic eruption. Westphalen and Chief Crocker, both people he outranked (he was the highest-ranking officer on the bridge at the time), decided to torpedo the base of the island to allow the magma to flow out into the ocean and saved the team by preventing the eruption. It is possible it was because of these actions that he soon after left the ship. Whether or not it was by choice was never mentioned.

Lieutenant Phillips was portrayed by actor Mark Fauser. Early scripts had his name listed as "Matthew Phillips" instead of Dalton. Phillips was also the only recurring character from the show (besides Admiral Noyce) to be featured in the novels.

Dr. Joshua Levin

A member of the seaQuest`s science and medical team.

Assigned to the Aqua Sphere 7 outpost later that year, Levin, as well as the rest of the away team became infected with an unknown virus spread to the station by the sunken French space station Liberté. He, along with the rest of the away team were eventually cured and he remained onboard seaQuest for the rest of the year.

Levin was well versed in ancient superstitions and beliefs which made him a valuable asset to the away team sent over to the sunken ship RMS King George when it was believed to be haunted. Levin also educated the military crew as to the effects of karstification while attempting to search for a downed French submarine in 2018.

Dr. Levin was portrayed by actor Timothy Omundson.

Chief William Shan

One of the helmsman of the seaQuest, Shan was born in Brazil in one of the favelas prior to the newly formed Amazonian Confederation and is a descendant of Vietnamese boat people. He possesses extensive knowledge of his people's background and speaks Portuguese. A capable combat officer, Shan was often part of Chief Manilow Crocker's security teams.

When an accident at World Power threatened to heat ocean temperatures and flood the polar ice caps, Shan disobeyed Captain Bridger's orders to abandon seaQuest, electing to remain onboard with his captain and Commander Jonathan Ford. Together, they were able to steer the seaQuest into a gaping lava well, detonate the ship's nuclear warheads, and plug the hole, effectively saving the world.

Chief Shan was portrayed by actor Dustin Nguyen. He was added to the series during the middle of the first season, and was intended to become a major character, but when the series relocated to Florida for production of the second season, Nguyen and several other cast members elected to leave the show rather than move.

Helmswoman Tyler

One of the helmsman of the seaQuest, Petty Officer Tyler joined the crew in early 2022, replacing Helmswoman Mackay.

She faced some difficult situations during her tour on the ship. She was on duty when the UEO was being threatened by a powerful psychic, known as the Avatar, she was able to overcome the side effects caused by the "psychic battle" between Smith and the Avatar and keep control of the helm. After Tony Piccolo "borrowed" a prototype personal cloak suit, Lucas made using cloned data from a classified South American project that the UEO shut down, the suit fritzed out when he snuck into the women's shower and locker room. When she caught him and (along with some of the other female personnel present) stripped him down and sent him running back to his room naked instead of reporting him. She was one of the helmsman on duty when a large barrier mine hulled the seaQuest after the ship had been forcibly abducted from Earth and taken to the distant water world known as Hyperion.

Helmswoman Tyler was portrayed by actress Dorian Field.


Malcolm Lansdowne

A long-time friend of Nathan Bridger's (whom nicknamed Lansdowne "Downy"), Malcolm Lansdowne maintained a dolphin research facility in the Caicos Key. When Darwin took ill during a mission to investigate a black smoker, Lansdowne was able to eventually determine that it was the bacteria in the smoker that had infected him in the first place.

When Max Scully had attempted to thwart the efforts of whaling ships, he borrowed an extensive amount of money from Lansdowne in order to purchase an old-style Foxtrot class submarine to combat the whalers.

Lansdowne had developed an attraction to Dr. Kristin Westphalen and invited her to his home in order to experience a virtual reality simulator that makes the user believe they are swimming with a pod of dolphins. Bridger, however, did not necessarily approve of Lansdowne's attraction to Westphalen, harboring feelings for her, himself. However, Lansdowne's advances towards Kristin were interrupted by deposed dictator Milos Tezlov attacked his house and held he and Westphalen hostage. Planning to train his dolphins for militaristic purposes, Westphalen noticed that Tezlov's autistic son Caesar was fascinated by the dolphins and struck a deal with him to spare Lansdowne's life in exchange for passage aboard seaQuest. When Tezlov eventually agreed to turn himself over to his enemies to spare seaQuest from destruction, Westphalen implored Lansdowne to care for Caesar as he had the time and the dolphins, to which he ultimately agreed.

Malcolm Lansdowne was portrayed by Robert Engels, who was also a co-executive producer on seaQuest DSV.

Martinson Hologram a.k.a. "The Old Man"

Although not really Bridger's friend, the holographic representation of Professor Martinson was designed to offer a sounding board to the ship's captain in the event of a crisis. Although the navy refused to install the program, Lucas brought him on-line nevertheless. During his first year as captain of the seaQuest, Bridger confided in Martinson frequently and the hologram was able to provide invaluable information as well. When environmental extremists captured seaQuest, Martinson was able to adequately distract one of them, allowing Lieutenant Krieg to lock him inside Bridger's quarters.

For a long while, Bridger did not consult the Martinson hologram, something he became aware of. While the hologram wasn't really a person, he did sometimes "remember what life was like." The final time Bridger consulted him, Martinson concluded with "God be with you, Nathan. I'll be thinking about you." Afterwards, Bridger consulted several other holograms, such as a psychiatrist and a priest.

According to the script of the season 2 episode "The Sincerest Form of Flattery", the hologram was an attempt to preserve the life of Martinson after the real professor had died.

The Professor was portrayed by actor W. Morgan Sheppard.

Dr. Raleigh Young

A specialist in underwater volcanoes, Dr. Raleigh Young had developed a special "magma buoy" which could be launched into an undersea volcano and remain functional, despite the intense heat, which would allow researchers to know in weeks what originally would have taken years. Somewhat hypersensitive, Dr. Young could not understand why Captain Bridger would choose to worry about a sick dolphin rather than his important research. However, he soon came to understand Bridger's reasoning and implored him to seek a cure for his ailing friend. His magma buoy was eventually launched.

Months later, the buoy rocketed out of the volcano and crash-landed on a deserted island where a group of fortune hunters searching for Stede Bonnet's desk. The hunters, believing the UEO to be encroaching onto their treasure, refused to believe Dr. Young when he told them that the island they were on was about to be destroyed by a volcanic eruption. With further convincing, they agreed to leave the island, but before they could depart, one of the treasure hunters destroyed the seaLaunch, stranding the fortune hunters, Dr. Young, and Commander Ford on a doomed island. Attempting to ease their fear of death, Dr. Young informed the group that there wouldn't be time to feel pain, as the lava would wash over them like a sea of fire. However, aboard seaQuest, Dr. Westphalen theorized that if enough torpedoes were fired at the vent of the volcano, it would ease the eruption. Her plan worked and the group was spared.

Dr. Young was portrayed by actor Roscoe Lee Brown.

Commander Scott Keller

Commander of the space shuttle Wayfarer, the first manned Earth vehicle to reach Mars and back, Scott Keller had attended the naval academy with Nathan Bridger, with whom they remained competitively friendly. One night, as a favour to Bridger, Scott ate a dozen and a half of Organa Watt's, the woman who ran the women's dorm at the academy, terrible cookies so Bridger could sneak a girl out the back. However, while Keller opted for outer space, Bridger opted for inner space. Bridger and seaQuest eventually rescued Scott's Wayfarer capsule after an accident during re-entry forced them to splashdown near the Montegnard Confederation.

Later that year, when seaQuest discovered a million year old alien ship entombed in a rock face, Keller joined the seaQuest away team over to the vessel where they discovered holographic projections still active even after a million years. With the aliens seeking peaceful relations with the human race, Lucas allowed Scott to send the message to their homeworld inviting them back. However, Scott gave the honor to Bridger who said, "You've shown such great patience. Now, hurry."

Their message was quickly received by aliens, who arrived on Earth in 2021. Ever curious about interstellar technology, Scott took a seaCrab over to their ship to take a look at their cockpit. However, following their encounter with the human race, the aliens reversed time. In the altered timeline, it was if the aliens "got spooked" and decided not to land on Earth.

When a comet believed to contain absolute matter prepared to splash into an ocean, Scott once again came aboard seaQuest to help recover it. With the help of Professor Tobias LeConte, one of Scott's oldest and dearest friend's, tracking sensors, seaQuest discovered that the comet had traversed the entire known universe in only six weeks. Unfortunately for Scott, the comet seemed to burn itself out before he could study it. As it turns out, the comet was in fact, a hatchery for an alien predator that impregnated itself aboard seaQuest and began to attack the crew. Looking for Tobias, the alien "Stormer" tracked him to his university. Rushing to his friend's aid, Scott was shocked to find that Tobias was an alien as well. Upon the death of the Stormer, Tobias knew he could not remain on Earth and invited Scott to join him on an interstellar voyage to find new worlds. Scott departed the Earth, leaving Lucas and Bridger to wonder if he would ever come back.

On May 14, 2022, a starship from Hyperion forcibly drew seaQuest from the water and inside their vessel where they returned to their homeworld. The crew, led to believe that they were needed to help defend their rebellion against the KrayTaks, the overlords of the planet, destroyed an alien submarine thought to be attacking them. When the seaQuest investigated the wreckage, they found Scott among it, barely alive. Scott was able to inform them that seaQuest had been fighting for the wrong side and that they must destroy the KrayTak mothership to ensure the safety of both the rebellion and Earth. Joining the away team, Scott and the crew were able to destroy the alien ship, only after seaQuest had appeared to be destroyed and the crew had been killed. Although the seaQuest and the crew were returned to Earth, Scott's fate remained a mystery.

Commander Keller was portrayed by actor Kent McCord.

Professor Tobias LeConte

Blinded by the magnificent light of a comet, Tobias was a child prodigy. At seven years old, he pinpointed the exact moment the universe was born. By age fourteen, he held Isaac Newton's chair at Cambridge. However, he was not fully human. Born on the planet Hyperion, eleven million light years away from Earth, Tobias sent out a message of peace on a planet of conquest. His anti-expansion philosophies branded him a traitor for which he was sentenced to death. He fled to Earth and melded with the real Tobias LeConte, essentially giving the child life as the comet that blinded him, also would have given him cancer, which his alien physiology was able to naturally fight off.

When a Stormer traveled to Earth to kill him, Tobias had no choice but to reveal his identity to his long-time friend Scott Keller and to leave Earth in order to save the planet from Hyperion conquest. Taking Scott with him, the duo set off in a starship he had secretly constructed in search of new worlds. However, they did eventually return to Hyperion where they joined the rebellion against the militaristic KrayTaks. On a mission to destroy the KrayTak mothership, Tobias was captured and had his memory drained so a Stormer could impersonate him. This Stormer-clone was sent to seaQuest, which had been captured by the KrayTaks and brought to Hyperion, in order to convince the crew to fight for their side. Fortunately, Scott, along with the seaQuest crew was able to free Tobias and destroy the mothership.

With Hyperion safe for the moment, Tobias and some of his rebel friends were able to liberate some rescue pods and return the majority of the seaQuest crew, who had been in a form of stasis since the destruction of the mothership, and the seaQuest itself back to Earth; a process which took ten years to complete.

Tobias LeConte was portrayed by actor Mark Hamill.


Maximilian "Max" Scully

A radical environmental activist who faked his death in the year 2011 after being disfigured by a bomb explosion he intended to use himself. By the late 2010s, Scully had borrowed money from Malcolm Lansdowne to purchase an old Russian Foxtrot class submarine which he and his crew originally used to monitor the movements of illegal whaling ships. Convinced that the UEO wasn't going to do anything about the whalers, Scully took matters into his own hands and began firing live torpedoes at the whalers. Unfortunately, during one such instance, a torpedo missed its intended target and sank a cruise ship accidentally. His crew abandoned him and Scully eventually was apprehended by the seaQuest. Rather than be taken into custody, Scully launched himself out of a torpedo tube, leaving Captain Bridger to destroy his abandoned vessel. Scully was believed to be all but dead considering that he was nowhere near any land masses and had no choice but to swim to save himself.

Somehow, Scully was able to survive and developed an undersea colony dedicated to the preservation of the Earth called "Ecotopia." Although he was still wanted for the deaths of the passengers of the cruise ship, the UEO granted him a full pardon when Ecotopia became a member of the UEO in 2032. Scully's ideals still had not changed as he took advantage of his tour of seaQuest to tap into the main computer of the sub. From Ecotopia, he was able to disable the ship's life support system and directed seaQuest`s pulse lasers at an underwater nuclear waste dump - the intention being to destroy the Human race, save for those within Ecotopia, whose descendants would return to the surface of the Earth generations later and protect the planet's environment, rather than ravage it. Fortunately, Scully was defeated by Captain Hudson, Lucas, and Elaine Morse, his plans thwarted, and a nuclear holocaust averted. Lucas hoped though that the peaceful Ecotopia colony was Scully's legacy, not his lunacy.

Max Scully was portrayed by actor Jonathan Banks. Before returning in the third season as Scully, Banks was on the short list to take over for Roy Scheider as the new star of the series.


Leader of the G.E.L.F. colony uprising, Mariah sought freedom for her and her people on their twenty first birthday in 2021. First seizing control of the colony, she led a group of daggers to UEO Headquarters in New Cape Quest. Once there, she captured General Thomas and a fully armed Navis-18 UEO submarine. Using Thomas' military command codes, she was able to gain access to the Ronald Reagan Memorial Laser Space Base where she plotted to destroy enough the world's air exchange plants, which would suffocate the human race, leaving the G.E.L.F.s as the only sentient life on the planet. She halted her plan when she realized that the G.E.L.F. baby that had recently been born at the colony was more human than her parents were due to spontaneous evolution and that destroying the human race would result in the ultimate destruction of the G.E.L.F.s as well. She released General Thomas and was imprisoned in a UEO detention facility.

Months later, a group, apparently being led by Commander Ford, broke Mariah out of prison and took her to an underwater complex run by disgraced scientist Dr. Russ Ketchum, AKA "The Marauder." Dr. Ketchum had intended to destroy seaQuest in order to freely mine "Marauder Reef" for prehistoric insect fuel, which he believed to be the missing element in cold fusion and intended to use Mariah's desire for revenge against seaQuest to serve his own interests. Giving Mariah a fully armed and automated submersible, she captured Lieutenant O'Neill, who had taken thirty days of shore leave, and used him to gain access to seaQuest`s stealth codes. She fought a pitched battle with seaQuest, but, ultimately ran out of torpedoes. Commander Ford agreed to allow her to escape for the return of O'Neill, to which she agreed, although Ford promised that seaQuest would eventually catch up to her again.

Mariah was portrayed by actress Sam Jenkins.


President Hoy Chi

President of the Montagnard Confederation, Chi had wished his state to remain a peaceful and supportive member of the UEO, but, also an important player within it. When the Wayfarer, the first manned space shuttle to reach Mars crash-landed in his confederation's waters, he ordered his fleet to attempt to locate them before seaQuest could, but, not to interfere with them if they found it first. Unfortunately, Chi's general, Tran, had other ideas, and planned to hold the astronauts (as well as two members of seaQuest`s crew) hostage. Chi was able to thwart Tran's plans, though. Shortly thereafter, Chi, along with other leaders of various confederations, as well as Lucas Wolenczak, were held hostage by Secretary General Dre, in an attempt to declare martial law over the UEO. Due to Lucas' and Bridger's quick thinking and action, Chi and the other hostages were eventually freed.

President Chi was portrayed by actor James Shigeta.


A member of the Node Three team, Julianna, AKA "Red Menace", was a brilliant computer hacker who worked alongside Martin Clemens (AKA "Mycroft") and Nick (AKA "Wolfman") in an attempt to make right the perceived wrongs of the world by diverting stolen funds from corrupt governments into places where they would be better served, such as hospitals. Julianna and Nick knew Lucas (AKA "Frankenstein") only through the Internet and the "Internex", via chat rooms and online games, but sent a message to seaQuest asking for him to come to Node Three to meet with them. Once there, Lucas, Julianna, and Nick were able to hack into the World Bank account where Clemens believed they would be able to make the world better. In actuality, Clemens was seeking a way to clear his own conscience after his computer hacking led to the death of a man. While at Node Three, Lucas and Julianna became attracted to one another. When Lucas returned to seaQuest, Julianna was sad to see him go.

Several months later, a mutual friend named Biff Pickering, invited both Lucas and Julianna to a secret party being held at the Sanger Institute. Biff led Lucas to believe that Julianna wanted to "go all the way" with him, but when they finally met up at the party, alone in a room with a bed, both felt that they weren't ready for sex and agreed not to go through with it.

Julianna was portrayed by actress Sarah Koskoff.
