Dark Angel is an American television series created by James Cameron and Charles H. Eglee. The series premiered in the United States on the Fox network on October 3, 2000. Max Guevara, portrayed by Jessica Alba, is the protagonist of the series. The first season had an additional seven regular characters. Two of these characters, Kendra Maibaum and Herbal Thought, did not return for the second season, and a third main character, Colonel Donald Michael Lydecker, was written out of the show shortly into the second season. Four new characters, however, become regulars for the series second and final season.

The series was continued with three canonical novels; "Skin Game" picks up directly where season two ended, and was followed by the final media in the Dark Angel universe, "After the Dark". A prequel novel, "Before the Dawn", chronicles Max's life between escaping from Manticore, the government facility that created her, and the beginning of season one of the television series. An apocryphal Dark Angel video game adaptation features the series' characters Max Guevara, Logan Cale and Original Cindy.

Main characters Max Guevara / X5-452

Max Guevara (portrayed by Jessica Alba and Geneva Locke as Young Max (seasons 1–2)) is the main character in all Dark Angel media. She is a genetically enhanced transgenic super-soldier who escaped from Manticore, the government facility that created her and gave her the signalled code (X5-452). She can be identified by the bar code on the back of her neck, which reads the number 332960073452.

Logan Cale / Eyes Only

Logan Cale (portrayed by Michael Weatherly (seasons 1–2)) is a cyber-journalist who uses his knowledge of computer technology to bring down the corrupt power brokers of the new millennium. Heir to a family fortune, Logan hacks into television cable networks and delivers his broadcast entitled Streaming Freedom Video under the pseudonym and alter ego "Eyes Only". When he discovers Max trying to burgle his apartment, Logan notices her Manticore barcode and offers to help her locate the other Manticore children in return for helping him on a vigilante mission. Max denies his offer, and Logan is rendered a paraplegic after he is shot on the mission. Max later accepts Logan's original offer, and the two form a close friendship and romantic interest. After receiving a blood transfusion from Max, Logan temporarily regains the ability to walk due to her stem-cell enriched blood.

Logan is a minor character in the prequel novel, Before the Dawn, after he recruits the X5 Seth to work for him. He is a major character in the novels Skin Game and After the Dark and the video game adaptation (voiced by Weatherly), where he continues to assist Max and the transgenics in the same way he did during the series. After the Dark, the final Dark Angel story, ends with Logan and Max finally consummating their relationship.

Colonel Donald Michael Lydecker Colonel Donald Michael Lydecker (portrayed by John Savage (season 1, recurring season 2)) is one of Manticore's senior officers and the main antagonist of the first season. He repeatedly attempts to recapture Max and the other X5s. After he is betrayed by his boss Renfro, Lydecker switches sides and helps Max and Logan prepare to destroy Manticore. He becomes a valuable ally in the fight against Manticore but disappears under mysterious circumstances early in season two.

Lydecker is a major antagonist in Before the Dawn. He only resurfaces in the final chapter of "After the Dark", where it is revealed he has been held prisoner by the breeding cult. When Max discovers him she initially decides to leave him there to die, but when Lydecker promises to help her find her mother if she saves his life Max reluctantly agrees.

Cynthia "Original Cindy" McEachin Cynthia "Original Cindy" McEachin (also known as O.C.; portrayed by Valarie Rae Miller (seasons 1–2)) is Max's best friend and a coworker at Jam Pony, where she frequently covers for Max, allowing her to keep her job. In the middle of season one, she discovers that Max is an escaped supersoldier from Manticore and, after some debate, becomes her roommate. At the start of season two, O.C. learns that Logan is Eyes Only. She usually refers to herself in the third person. Despite being a lesbian, multiple sources commented on the fact O.C. was never shown kissing another woman during the first season, (though she later did in the episode "Shortie's in Love") with Miller saying "The censors watch me more than anything". In 2009 AfterEllen ranked her at No. 6 on their list of the Top 11 Lesbian/Bi Sidekicks.

O.C first meets Max in the prequel novel Before the Dawn, when Max comes to her aid during a bar fight. She is a main character in Skin Game, where she is kidnapped by a transgenic serial killer, and also has a minor role in After the Dark, where she continues to be one of Max's closest friends. She also appears as a non-playable character in the Dark Angel video game, where she is voiced by Debbie Timmis.

Reagan "Normal" Ronald

Reagan "Normal" Ronald (portrayed by J. C. MacKenzie (seasons 1–2)) runs the Jam Pony Express courier service and is nicknamed Normal because his conservative attitude clashes with his somewhat anarchic surroundings. He is a hard taskmaster, often annoyingly saying "Bip, bip, bip!" to mean "hurry!" In addition to disliking and being disliked by most of his workers, he becomes anti-transgenic in the second season after the existence of Manticore's creations becomes public. However, Normal dotes on Alec and calls him his "golden boy", unaware that he is a transgenic. In the series finale, he skillfully helps an X-5 deliver her baby and later completely changes his opinion on transgenics.

Normal is described in Before the Dawn, when Max begins working at Jam Pony. Normal makes an appearance in After the Dark when Max visits Jam Pony. Max is pleasantly surprised at Normal's change in attitude, when he shows compassion for both her and O.C.

Calvin Simon "Sketchy" Theodore Calvin Simon "Sketchy" Theodore (portrayed by Richard Gunn (seasons 1–2)) is Max's friend and coworker at Jam Pony. Described as a "hapless" character, Sketchy often found himself in trouble and needing Max's assistance. In the second season he gets a second job as a freelance journalist and attempts to photograph transgenics, taking a dislike to them in the process. After learning that Max and Alec are transgenics during the Jam Pony siege, Sketchy changes his mind and helps the transgenics escape to Terminal City.

Sketchy briefly appears in Before the Dawn, when Max becomes friends with him after she begins working at Jam Pony. Sketchy also plays a minor role in the final two Dark Angel novels. In Skin Game, at the suggestion of Logan, Sketchy leaves Terminal City to become a pro-transgenic reporter for a tabloid newspaper, and is shown to have succeeded in doing so in the sequel After the Dark.

Herbal Thought Herbal Thought (portrayed by Alimi Ballard (season 1)) is another of Max's friends and coworkers at Jam Pony. A heavily accented Rastafarian and marijuana enthusiast, Herbal was said to be an "urban philosopher" who "offered wise counsel" to Max. His character does not appear in season two, and no explanation is given for his disappearance.

Herbal briefly appears in Before the Dawn, when Max becomes friends with him after she begins working at Jam Pony.

Kendra Maibaum

Kendra Maibaum (portrayed by Jennifer Blanc (season 1)) is Max's friend and roommate for season one. Her life "revolves around dating, going out, partying and dressing up." Her character moves out of Max's apartment during season one to go and live with her boyfriend and subsequently disappears from the show.

Max first meets Kendra in Before the Dawn. After Max defends Kendra from her boss who was sexually harassing her, Kendra offers to let Max, who is looking for a place to live, become her roommate.

Alec McDowell/X5-494

(portrayed by Jensen Ackles (season 2)) is named by Max (for him being a "smart aleck"). He is introduced as Max's breeding partner at Manticore, an order which is vehemently denied by Max. Alec is also the identical twin of / X5-493, one of the original 12 escapees from Manticore. Ben (who was also portrayed by Ackles) appeared and was killed in the season one episode "Pollo Loco", and Max finds Alec's resemblance to him difficult to handle at first. When Manticore is destroyed, Alec escapes to the outside world. A genetically enhanced super-soldier, he makes money using questionable means, while wheeling and dealing. However he often follows Max's example, working at Jam Pony, and being a cat burglar. Alec often presents a cavalier attitude to the world while hiding his darker emotions. He is at first a self-absorbed magnet for trouble, but becomes a valuable ally for Max, and eventually, her friend.

Alec is a main character in the final two Dark Angel novels, continually assisting Max as one of her most trusted allies.

Joshua

Joshua (portrayed by Kevin Durand (season 2)) is an early Manticore experiment who's engineered with canine DNA and consequently has some unusual facial features, as well as incredible strength even by transgenic standards. As the very first successful Manticore creation, he has no bar code. At Manticore, he often roams in the basement unchecked, and takes care of the rest of the "downstairs people" by giving them food. He and Max develop a very close friendship, and he often imitates some of the words she says, because of his unfamiliarity with normal speech. His beastly appearance causes the team to seek creative ways to hide him from public view. He has a brief romance with a blind woman named Annie Fisher before Agent White murders her and frames Joshua for it. His enormous strength also helps turn the tide during the battle with the cult members at the Jam Pony siege in the series final episode.

Joshua is a main character in the final two Dark Angel novels, continually assisting Max as one of her most trusted allies.

Ames White Ames White (portrayed by Martin Cummins (season 2)) was the second season's primary nemesis of Max. He is a government agent charged with tracking down and exterminating Manticore escapees in order to conceal the organization's existence. He is also part of an ancient cult, known only as the "Conclave", that has infiltrated various levels of society, and over millennia, bred super-humans that are formidable fighters equal to most of the results of the Manticore projects.

White plays the main antagonist in the final two Dark Angel novels. Joshua kills him by ripping off his head towards the conclusion of "After the Dark".

Asha Barlow

Asha Barlow (portrayed by Ashley Scott (season 2)) is a member of S.1.W., a militant resistance movement against government corruption. She works closely with Logan on Eyes Only missions but does not know Logan is Eyes Only. She believes, like Det. Matt Sung and most other Eyes Only contacts, that Logan is a messenger for him. Asha has a romantic interest in Logan. She and Alec also almost sleep together in one episode, but nothing comes of it.

Asha makes a brief appearance in the novel After the Dark, where she gives Max some vital information to assist her in rescuing Logan.

Recurring characters Bling Bling (portrayed by Peter James Bryant (seasons 1–2, 14 episodes)), Logan's live-in physical therapist, assists him when he becomes disabled and needed to use a wheelchair, up until he meets Phil (Rainn Wilson), in the episode "I and I Am a Camera", who provides him with an exoskeleton allowing him to walk.

Det. Matt Sung Det. Matt Sung (portrayed by Byron Mann (seasons 1–2, 8 episodes)) is Logan's trusted police contact who often provides information or otherwise aids him. Matt Sung appears in both seasons in a recurring role.
