The Core Group

    Dr. Alan Farragut 
Played by: Billy Campbell
“When a surgeon fumbles, the patient dies. When WE drop the ball, thousands die.”

    Dr. Peter Farragut 

Played by: Neil Napier
"Something about being trapped in this place. I see that bastard around every corner."

     Dr. Julia Walker 

Played by: Kyra Zagorsky
"Get it together, Jules! You. Don't. Get. Sick."

  • Face-Heel Turn: If the first season finale is any indication.
  • Glowing Eyes: After Hatake somehow cures her from infection, her eyes become the same luminescent silver color as his, implying that this unnatural eye color is a side effect of the cure. Hatake provides her with contacts of her original eye color with which to mask them in the following episode after Julia discovers that her new eyes have an extreme sensitivity to bright lights.
  • Helpful Hallucination: When she realizes The Virus is causing her subconscious to manifest Jaye.
  • I Hate You, Vampire Dad: In essence, if not in fact, once Hatake reveals his paternity and nature to her.
  • Old Flame: With both Alan and Peter.
  • Trauma-Induced Amnesia: When infected by Peter. Then again, it may just be good old-fashioned denial/Blatant Lies.

    Dr. Sarah Jordan 

Played by: Jordan Hayes
“We are all waiting to die. I just have a little less time.”

  • Blessed with Suck: She became immortal when she was newly pregnant. When she stopped aging, so did the fetus. She's permanently in her first trimester, suffering from morning sickness and nosebleeds.
  • Fake Guest Star: Listed as a guest star despite appearing in every episode of the first season (which is actually one more than series regular Balleseros).
  • It Doesn't Mean Anything: After having sex with Alan, she denies any feelings the next episode, calling it simple biology. Alan, of course, is silently hurt by this.
  • Mercy Kill: Sarah does this to an infected patient to spare her from becoming one of the vectors.
  • Older Than They Look: Lampshaded. She looks like a teenager but is well into her mid 20's.
  • Secretly Dying: She has a brain tumor which causes her right hand to shake uncontrollably.
  • Surprise Pregnancy: Sarah discovers this in the first season finale.
  • Took a Level in Badass: Come Season 2, she has a reputation at the CDC for throwing herself willingly into the most dangerous situations, earning the nickname "Hot Zone." She looks at her acquired immortality as a gift that she needs to use to help make the world a safer place.
  • Your Days Are Numbered: She's trying to make the best of the time she has left.

    Dr. Doreen Boyle 

Played by: Catherine Lemieux
“Someone designed this virus and it sure as shit wasn't mother nature.”

  • Cruel and Unusual Death: Stabbed with a syringe by Balleseros thus giving her a embolism. It caused her to convulse violently then she has a shelf full of infected rats pushed on her which eat her ALIVE. Not an easy way to go, to say the least.
  • Deadpan Snarker
  • He Knows Too Much: Almost to the point of being invoked. Balleseros uses her to get the information he needs, then kills her so she can't tell anyone else.
  • Odd Friendship: With Balleseros
  • Snark-to-Snark Combat: With Balleseros.

    Major Sergio Balleseros 

Played by: Mark Ghanime
"Keeping the word from getting out on this shit show is one of my imperatives."

  • Affably Evil: Despite all the horrible things he does to plug potential leaks he is easy to get along with.
  • Apologetic Attacker: "Sorry, Doreen. I'm so sorry."
  • Back Stab: His preferred method of dealing with the unfortunate people who know too much.
  • Badass
  • Being Evil Sucks: Grows increasingly disgusted with himself over the things he's done like killing Doreen or kidnapping the children. May be the reason for his eventual (apparent) Heel-Face Turn.
  • Cleanup Crew: His main purpose for being at the facility. Lampshaded.
  • Deadpan Snarker
  • Just Following Orders
  • Karmic Death: Daniel stabs him in the chest with an ice pick. The wound itself is not instantly fatal, so he proceeds to remove the Major's protective clothing, leaving him to be killed by the elements; similar to how Balleseros himself disabled Doreen and left her to be eaten by the rats.
  • Majorly Awesome
  • Odd Friendship: With Doreen. He kills her anyway.
  • Shirtless Scene: After being captured by Anana the camera lingers on his chest many times.
  • Snark-to-Snark Combat: With Doreen.
  • The Engineer: His purpose is to analyze the facility itself to discern structural methods of transmission.

    Dr. Hiroshi Hatake 

Played by: Hiroyuki Sanada
“You don't have the intellectual capacity to evaluate my work.”

  • Badass: He's able to get off three kill shots with a pistol with remarkable speed, and later stabs himself through the midsection as part a ploy.
  • For Science!: Appears to be his motivation.
  • Glowing Eyes: He hides his creepy luminescent silver eyes behind tinted contacts.
  • Katanas Are Just Better: He busts one out in Season 2. And he's old enough that he's probably used it himself in ye olden Samurai days.
  • Luke, I Am Your Father: He turns out to be Julia's father.
  • Morally Ambiguous Doctorate
  • Professor Guinea Pig: Implied by his use of said contacts.
  • Really 700 Years Old: He's apparently 513 years old, and only looks in his late thirties or so.
  • Scars Are Forever: His lower back is covered with them. He got them from a house fire trying to save his daughter. It's implied this might be a lie.

     Daniel Aerov/Miksa 

Played by: Meegwun Fairbrother
“I don't work for him. I AM his son.”

  • Blind Obedience: To Hatake. Hinted at by Balleseros. Despite this, he is still disturbed when Hatake kills three scientists who had surrendered their weapons, and voices his disapproval.
  • Bond One-Liner: "Got a reply for that message!"
  • The Dragon: To Dr. Hatake.
  • Even Evil Has Standards: As mentioned above, he is visibly disturbed upon witnessing Hatake's murder of three infected scientists after they had surrendered. It is this event that prompts him to start to question whether his Undying Loyalty to Hatake is well placed.
  • Fake Guest Star: Daniel appears in 12 of season 1's 13 episodes (and actor Meegwun Fairbrother appears in all 13) but is listed among the guest stars.
  • Genre Savvy: After Balleseros ambushes him out in the snow, he survives due to the heavy protective clothing he was wearing. When he returns the favor and takes out Balleseros, he makes sure to remove the Major's layers so that he won't be so lucky.
  • Happily Adopted: To Hatake, who raised him. Until he's told that he had been kidnapped from his village by Hatake when he was a child
  • Heroic Sacrifice: He triggers the explosive collar himself, fully knowing that it will result in his own death, in order to spare Hatake from having to make the Sadistic Choice of who to save between him and Julia.
  • The Resenter: In Season 2 he comes to resent Hatake's favoritism toward his biological daughter Julia at his expense. Of course, by this point the Daniel we're seeing is just a hallucination of Hatake's, so he might be projecting his own guilt.
  • Took a Level in Badass: Ambushes Balleseros with an ice pick, strips him of his protective clothing, then leaves him to die exposed to the elements.
  • Your Head Asplode: His head is blown off by an explosive collar.

Ilaria Corporation

     Constance Sutton 
Played by: Jeri Ryan

  • Off with His Head!: Hatake decapitates her and puts her head in cryogenic storage for reasons as-yet unknown.
  • Older Than They Look: She's an old friend of Hatake's, and considering Hatake is over 500 years old, she could conceivably be even older.

     Spencer Chissik, aka "The Scythe" 
Played by: Robert Naylor

     Klein 
Played by: Christian Jadah

Saint Germain Island Cult

     Michael 
Played by: Stephen Webber

  • Dissonant Serenity: He's preternaturally calm despite everything that's going on.
  • Evilutionary Biologist: A surprisingly low-tech version: his commune is a farm that used old-time selective breeding and plant grafting techniques. This includes his own bloodline.
  • Faux Affably Evil: And how.
  • Older Than He Looks: He's a "silver-eye" Immortal, so he's at least 500 years old.
  • Wife Husbandry: A disturbing example: he's been impregnating his own daughters for at least three generations, in an attempt to breed another Immortal.

     Agnes 
Played by: Claire Coulter

  • Mad Scientist: Of the agricultural variety. She's bred all kinds of strange plants over the years
  • Team Mom: For the Cult.
  • You Know Too Much: Michael kills her for figuring out there are other Immortals out there.

     Anne

     Amy

Other Characters

     Anana 
Played by: Luciana Carro

     Toluk 
Played by: Meegwun Fairbrother

  • Acting for Two
  • Badass: He's pretty tough, able to hold his own against trained mercenaries.
  • Big Brother Instinct: With Anana, going so far as to threaten Balleseros with bodily harm if he hurts her.
  • Gentle Giant: Unless you piss him off.
  • Separated at Birth: Technically, they were separated as very young children, but "Daniel Aerov" is actually his long-lost twin brother Miksa.
