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 a sharp raise in the temperature of the water in the South Atlantic, caused by an undersea mining operation, a deinosuchus (gigantic prehistoric crocodile) thawed out and was threatening the local ecosystem and the life of the local people. With the help of his family they stopped to creature and settled their differences. Ford's father decided to take a year off from work and give Jonathan's younger brother Ben the run of the company. His mother is deceased.

Appointment to seaQuest

Part of the original seaQuest'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.

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) and was a lot more interested in seaQuest's exploration and research mission and not just the military and peacekeeping aspect. . The character had a romance with Lonnie Henderson in the shows third season, although this fizzled out after Henderson had to shoot someone she used to love in order to save Ford.

Background

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. 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) this was disregarded for the rest of the series.

Lieutenant Commander Katherine Hitchcock

First appearance	To Be or Not to Be (09/12/1993)
Last appearance	Higher Power (05/22/1994)
Created by	Rockne S. O'Bannon
Portrayed by	Stacy Haiduk
In-universe information
Gender	Female
Title	Lieutenant Commander
Occupation	Chief Engineer of the seaQuest DSV 4600.
Spouse	Benjamin Krieg (divorced)
Nationality	American

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.

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.

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.

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.

As the seaQuest`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.

Background

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.

In-universe information
Gender	Male
Title	Lieutenant JG
Occupation	Communications officer of the seaQuest DSV 4600.
Religion	Catholic
Nationality	American

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.

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.

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. 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 and questioning Hudson's orders to fire on Captain Bridger's fleet. 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.

Background

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". 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." This is also why his name was Mac in the comic and non canon novels.
