Farscape

She is extremely arrogant, a self-styled polymath who constantly belittles those around her. While her knowledge about technology, species, history, and the galaxy in general is vast, it is mostly academic. She is extremely naive and unknowledgeable about how things function outside a controlled environment (such as learning Leviathan physiology strictly via studying and not understanding that the floorplans of the biomechanoids vary as a result of passenger preference). Sikozu's sense of self-preservation is foremost in her mind, and so she is prone to switching sides in any conflict with no notice and seemingly no premeditation other than ad hoc judgments on who currently holds the greatest advantage. This makes her true loyalties (if any) uncertain.
Sikozu Svala Shanti Sugaysi Shanu (called Sikozu), played by Raelee Hill, is a Kalish who grew up in Scarran-controlled space. She first appeared in "Crichton Kicks" and made her last appearance in "The Peacekeeper Wars Part 2". She becomes an expert (albeit a book expert) on Leviathans, and eventually goes to work for a pirate group who harvest toubray (nerve) fibers from Leviathans. 

Chiana, played by Gigi Edgley, is a street-smart, savvy, and mercurial type of character who is willing to scam or steal for an adventure and risk her life for the people she loves. Chiana is a Nebari, a grey-skinned race whose society is heavily regimented by the government (known as The Establishment). The Establishment venerates control and order, pitting Chiana's independent ways in a society all about conformity against the Nebari's ideal about "the greater good" and making her a target for government reprogramming (called "cleansing"). In her premiere episode during the middle of season 1, "Durka Returns", she successfully escapes from Nebari custody, and ends up a passenger on Moya with the rest of the crew.One of Chiana's other characteristic traits is her strong sense of individuality. She respects no authority and values her freedom more than anything or anyone else. This gives her the appearance of being promiscuous; she attempted to seduce Jothee, D'Argo's son, the present and past versions of John Crichton as well as others.

Pilot is effectively immobile in the heart of the ship, but plays a key role in numerous adventures, and the other characters come to rely upon him as a figure of wisdom and comfort. Early in the series he is attacked and mutilated by members of the crew, as a local scientist wanted Pilot flesh in return for giving them maps to their homes. Despite this, he did not hold a grudge as he considered serving the others, whatever their needs, to simply be his role. He was most happy when helping other crew members, although as his independence grew, he could sometimes become irritated with them and would order them out of his chamber and even off the ship altogether. In the series finalie, Pilot experienced a conflict with Moya where he wanted to help Crichton destroy the wormhole linking Earth to Tormented Space and Moya didn't want him to. Despite this and initially stating he could do nothing, Pilot joined the mission, leaving Moya for the first time in a long time to aid Crichton's plan. Though Pilot was left weakened by his separation from Moya, he succeeded in destroying the wormhole and saving Earth, inadvertently killing the crew of a Scarren Stryker in the process. He was later rebounded with Moya.

Pilot is a member of a race known to viewers simply as Pilots or "Servicers". He is introduced in the "Premiere" and plays a significant role in the resolution of The Peacekeeper Wars. Pilot was one of two regular animatronic puppet characters in Farscape. He is operated by Sean Masterson, Tim Mieville, Matt McCoy, Mario Halouvas and Fiona Gentle. His voice is provided by Lani Tupu (who also plays the character Captain Bialar Crais on Farscape).

Although Crichton is a heroic and unwaveringly loyal character, he is also a mischievously comical one, so much so that he is the primary source of humor for the series. The show derives much of its humor from Crichton's habitual (and extensive) use of Earth-related pop culture references, often used as witty mockery in the face of danger or opponents who, being unfamiliar with the references, are unaware that they are being insulted. Although an occasional reference will provoke curiosity or confusion to his friends, Crichton's fellow shipmates are largely unaffected by these comments because they simply assume them to be native Earth terms that cannot be interpreted by translator microbes and merely extrapolate the meaning from its context. 
John Robert Crichton, Jr./ˈkraɪtən/, played by Ben Browder, is an International Aeronautics and Space Administration (most commonly referred to on the show as IASA)astronaut who, in the opening few minutes of the pilot episode, is accidentally catapulted through a wormhole across the universe, thus setting the scene for the show as a whole. As the only regularly appearing human on the show, he is the main focus and is the main character as he narrates the weekly credits and is the only character to appear in every episode. 

Aboard Moya, she learns to think beyond the strict, militaristic confines of her Peacekeeper upbringing. Born in service aboard a Command Carrier, it is the only life she has known, and thus is very well skilled in hand-to-hand and weapons combat. She also becomes a valuable and important member of Moya's crew, and a companion and romantic interest to Crichton during the series. Aeryn evolves from a cold, detached soldier into a valuable friend and crewmate. Her relationship with John Crichton also evolves, and Aeryn ultimately becomes a compassionate wife and loving mother at the end of the show. They name their son D'Argo Sun-Crichton, after their dear friend who seemingly lost his life in the Peacekeeper Wars.Aeryn Sun/ˈɛrɪn ˈsʊn/, played by Claudia Black, is a former Peacekeeper pilot and officer. Although she appears to be human, she is in fact Sebacean, a species indistinguishable from humans in external appearance. At the time John Crichton appears through a wormhole in the beginning of the series, Officer Aeryn Sun is in her Prowler battling to retake the Leviathan Moya, which has been seized by escaping prisoners Ka D'Argo, Rygel, and Pa'u Zotoh Zhaan.

Jothee is the half-Luxan/half-Sebacean son of Ka D'Argo and his late wife Lo'Laan, played by Matthew Newton, and later by Nathaniel Dean. After the death of Lo'Laan, D'Argo left Jothee in the care of others. In the time between D'Argo giving him up and his reappearance, the details are vague. It was implied that Jothee spent time as a slave, as he was found among Banik slaves. 

As a result of his separation, Jothee was denied most of the Luxan upbringing and, after being the subject of abuse over his mixed heritage, mutilated his more Luxan features. 

While on Moya Jothee had an affair with Chiana, who was his father's lover, which caused a rift between both D'Argo and Chiana, and D'Argo and Jothee. Jothee left Moya's crew at this point.

 His whereabouts between his departure from Moya and PK Wars are unknown. Two cycles later, Jothee re-appeared as the "Kleeva" (a military strategist and officer) of a small Luxan commando unit during PK Wars. According to comic continuity later, Jothee's unique background helped him achieve the honor of becoming the youngest Kleeva in the history of the Luxan people. Jothee's skills are primarily tactic and mind based, unlike his father who quite often relied upon his brute strength, anger, and intimidating stature to get results.
