This is a character sheet for the British TV series, not the live-action American film.
Played by: Jack Davenport
A police detective recruited into the squad after investigating into the disappearance of his best friend and fellow cop, Jack.
- Agent Scully: Tends to look for mundane explanations for everything until proven otherwise.
- All Love Is Unrequited: Michael clearly has feelings for Kirsty, but the secrets he now has to keep from her, and the fact she may still love Jack, make any form of relationship impossible.
- Always Save the Girl: Michael goes out of his way to protect Kirsty, even going behind his teammates' backs and seemingly risking the future of humanity just to save her.
- Audience Surrogate: As the newest member of the team, he discovers the rules of the world along with the viewers.
- Deadpan Snarker: The entire team are like that, but Michael gets a few winning lines.After Pearse clears him of accidentally shooting a human during an investigationMichael: So that's it, then? "Two Hail Marys and don't shoot any more civilians"?
- Did Not Get the Girl: Both of his potential Love Interests reject him at the end of the series.
- The Heart: Subverted. Michael seems more caring compared to the rest of the team, but his empathy and compassion are often misguided, and ultimately used against him by the Code V's.
- Knight In Sour Armor: While he seemed to be reasonably well-adjusted in his former job as a police detective, the stress and moral dilemmas of his new workplace make him increasingly bitter and sarcastic, although no less determined to protect people.
- Naïve Newcomer: Seen as such by the rest of the team, especially when suggesting ideas such as that vampires are capable of love.
- Refusal of the Call: At first, telling Pearse he has no interest in joining the team, despite having encountered the Code V threat face-to-face. Changes his mind after the true magnitude of the issue is explained to him.
- Reluctant Warrior: Struggles with constant moral qualms regarding the team's goals and methods.
- Welcome Back, Traitor: Apparently. To be fair, although he did trade with the vampires behind the others backs, he tricked them and didn't provide what they wanted.
Played by: Idris Elba
The main muscle of the squad. An aloof ex-soldier.
- All Love Is Unrequited: Towards Angie. He Cannot Spit It Out, she is still hung up about her late husband, and nothing comes out of it.
- Better to Die than Be Killed: Almost shoots himself rather than fall into the hands of the leeches. Lucky he thought of something else.
- The Big Guy: The only military-trained member of the core team, and also the most willing to use violence.
- Cannot Spit It Out: His feelings for Angie.
- Jack Bauer Interrogation Technique: Nicely demonstrated on Colin the pedophile in episode 4.
- Jerk with a Heart of Gold: Genuinely cares for Angie, and starts really warming up to Mike towards the end of the series. Also shown when he decides to bring flowers to the paralyzed girl on episode 2.
- Kick the Dog: Literally, with the pedophile's dog on episode 4. It's fair to note that the dog was attacking him at the time, but Vaughan's callous attitude and the dog's pitiful whine still make it count.
- Hollywood Atheist: Although nothing is done to change this.
- Scary Black Man: Big, menacing, occasionally violent and played by Idris Elba.
- Shell-Shocked Veteran: The official reason for his discharge from the Army is PTSD following a friendly fire incident. The actual incident was different, and while it was very traumatic, its unclear how much he really suffers PTSD and how much of it was just a cover story to let him join the squad.
- Sociopathic Soldier: Seems like one at first. Has Hidden Depths.
- The Woobie: By the end of the series, everyone in the team has betrayed Vaughans trust in some way.
Dr. Angela March
Played by: Susannah Harker
The scientist and doctor of the squad.
- Dark and Troubled Past: Possibly has the most difficult back story of all the main characters.
- Determined Widow: Unlike most examples, determined to stop the creatures her husband chose to join.
- Hot Scientist: Not at all bad-looking, as noticed particularly by Vaughan.
- Jerk with a Heart of Gold: Angies ruthless professionalism comes off as cold, but we get glimpses of a kinder personality underneath.
- My Beloved Smother: Angie keeps tight control on her remaining daughter's life, forbidding her to leave home after dark and apparently not giving her much privacy. Not that she lacks good reasons, mind.
- Omnidisciplinary Scientist: Averted. While being the team's only scientist, Angie is a physician specializing in hematology and is never shown doing anything science-y which is not related to her field of expertise.
- The Smart Guy: Responsible for the scientific and forensic side of investigations.
- Staking the Loved One: For her husband and one of her daughters.
Played by: Philip Quast
A former Catholic priest and the leader of the squad.
- Agent Mulder: Always the first to suspect Code V involvement in everything.
- Badass Preacher: Or Church Militant, depends on whom you ask.
- Death by Irony: Well, Terminal Disease by Irony. Pearse might have gotten his lymphoma from overexposure to the sun.Pearse: The Sun giveth, the Sun taketh away.
- Knight Templar: The most ruthlessly determined of the team to rid the world of the Code V menace, seeing his job as a "vocation". He also refuses to listen to any suggestion that they might not all be completely evil. Judging by the finale, he's right.
- The Leader: Of the Code V extermination squad.
- No Medication for Me: Unusually, used with cancer medication. He claims he wants to avoid cognitively impairing side effects while on investigation; he just might be considering other options.
- Skunk Stripe: Played by Philip Quast, who has a noticeable one.
- Pre-Mortem One-Liner: Delivered to Paul Hoyle, after an episode-long Hannibal Lecture.
- Van Helsing Hate Crimes: The vampires accuse him of this. Judging by the ending, theyre probably lying.
- Your Days Are Numbered: Discovers mid-series that he suffers from slow-growing but incurable type of lymphoma.
Played by: Fiona Dolman
Michael's ex whom he constantly turns to for help and information.
- All Love Is Unrequited: She might still have some feelings for Michael, who doesn't seem to see her as much more than a friend and useful contact.
- Amicable Exes: Towards Mike, although he is less so towards her. We're never told what happened between them to cause this.
- Betty and Veronica: The Veronica to Michael's Archie and Kirsty's Betty. Ironically, at the end of the series she is the one urging Michael to behave sensibly while Kirsty lures him (unintentionally) into danger.
- Friend on the Force: She's Michael's Friend on the Intelligence Service.
- Get Out!: In the final episode, when Mike finally asks for something she feels she can't do. (Namely, helping him trade an unknown an possibly dangerous substance in exchange for Kirsty's life.
Played by: Colette Brown
Jack's fiancée. After his disappearance, her constant efforts to discover what happened to him put Michael in an uncomfortable position.
- Betty and Veronica: The Betty to Michaels Archie and Frances Veronica. She clearly dislikes the haughty and sophisticated Frances and believes (justly) that Frances looks down on her.
- Complaining About Rescues They Don't Like: Michael's rescue of her, while risking his job and possibly his life, earns him a slap on the face for his trouble. To be fair, she was probably mad about him resurrecting Jack to show her what he's become rather than about the rescue itself.
- Damsel in Distress: Unknowingly until the very last moment.
- Hot Teacher: Works as an elementary school teacher.
Played by: Stephen Moyer
Michael's best friend and Kirsty's fiancé. His disappearance at his wedding day eventually leads Michael to discover the truth about Code V's.
- Dirty Cop: Jack wasn't all that even as a human.
- Evil Former Friend: Was Michael's closest friend, although he was bent even before turning.
- Smug Snake: As a Code V, Jack is smug, mean and manipulative, but ultimately he's a pawn that gets taken down fast.
- Runaway Groom: Disappears the night before his wedding day, leaving his would-be wife and the wedding guests to wait for him in the church until it becomes clear he isn't showing up.
- Transhuman Treachery: With a side dish of human treachery.
- Not Quite Dead: Resurrected on the finale.
- One-Liner: "Get a life."
Played by: Thomas Lockyer
A tabloid journalist recruited by Kirsty to help her investigate into Jack's disappearance.
- Conspiracy Theorist: Looking for government conspiracies is apparently his specialty, and why Kirsty turns to him in the first place.
- FaceHeel Turn: Seemed to be more-or-less decent as a human, and willing to help Kirsty. As with all Code V's, once he is turned he quickly signs up for their cause.
- I Have Your Wife: Well, he has an unrequited love interest...
- Intrepid Reporter: An investigative journalist, although with less-than-sterling reputation.
- Smug Snake: When he drops his pretenses.
- Transhuman Treachery: As poor Kirsty eventually learns.
- Vomit Indiscretion Shot: What happens when a Code V eats human food?
John Doe/ Paul Hoyle

A senior Code V captured 'alive' by the squad.
