Played by: Linda Cardellini
Appeared in: "Cura Te Ipsum"

A physician who spent her adult life stalking her sister's rapist to get revenge.

  • Crazy-Prepared: She's devoted a great deal of time to committing the perfect murder of her sister's rapist. Reese is extremely impressed in particular at the measures she's taken in preparing for her target's disposal once she's killed him.
  • Hospital Hottie: She's a doctor, and there's plenty of interest in her when she turns up to bars.
  • Naughty by Night: Subverted. She plays this up to find her sister's rapist.
  • Revenge: Her entire motivation is based around killing the man who raped her sister.
  • She Who Fights Monsters: Reese warns her about the danger of this trope and convinces her to let him punish her target instead so she doesn't have to live with blood on her hands.
  • Sympathetic Murderer: A would-be version; she's trying to kill the man who raped her sister.
  • This Cannot Be!: Reese is just a stranger she's met at a victims group, yet he somehow turns up to avert her plan, knowing everything about her. Megan breaks down at the sheer impossibility of it all.

    Zoe Morgan 

    Charlie Burton 

    Wallace Negel 

Wallace Negel/Ulrich Kohl
"For my country, I left my country and killed wherever they sent me. For that they called me a monster."
Played by: Alan Dale
Appeared in: "Foe"

A former East German Stasi spy who was betrayed by members of his unit, and planned to eliminate his former colleagues.

  • The Chessmaster: Has had a while to draw up a plan to track down and get rid of his former colleagues while in jail and executes it in a very efficient, methodical manner.
  • Cold-Blooded Torture: His preferred form is acupuncture needles to major nerves. Very clean and intensely painful.
    Kohl: They laughed at me when I learned to use these needles. They didn't laugh long.
  • Combat Pragmatist: Kohl opts for the quickest method of disabling an opponent. Case in point with Reese where he hands his pistol to Reese while at gunpoint, using his other hand to deliver a well-placed nerve strike.
  • Cool Guns: His Weapon of Choice is a Welrod, a World War II-era bolt-action pistol with an integrated suppressor that renders it extremely quiet (by gun standards).
  • Cool Old Guy: He's an ex-German spy with a lot of experience who can outfight Reese.
  • Driven to Suicide: After he's informed that his wife is alive and meets with her, she informs him she's completely terrified by him and as he's got nothing else to live for, purposely makes Reese kill him by levelling his empty gun at his wife. As Kohl said he didn't have a tomorrow, it's implied that he would have killed himself once he'd finished.
  • Even Evil Has Loved Ones: The whole reason why he's back in New York, to take revenge for himself and his wife. And when his wife reveals she's utterly terrified by him, he decides to make Reese kill him as he's got nothing left to live for.
  • Evil Old Folks: Despite being well into his old age, he runs rings around the young German intelligence officer sent to take him down and has the honor of being the first person seen in the show who can go head-to-head with Reese, stay one step ahead of him and even incapacitate him with a well performed nerve strike.
  • Friendly Enemy: He is very friendly to John. They bond over discussing tradecraft and costs of being a professional killer while Kohl is taking breaks between torturing Reese. He's also highly regretful when he has to depart while at the same time is preparing to plug John in the head. Later after their final confrontation, they have a rather touching yet bitter-sweet conversation as Ulrich bleeds out on a park bench.
  • Genius Bruiser: Kohl isn't just a Professional Killer; he is also knowledgable in chemistry (he mixed the hydrogen cyanide he used on Wernick himself) and anatomy, which he uses to great effect on Reese by subduing him with a well-placed nerve strike and often used in his needle torture.
  • Heel Realization: He eventually realizes what he's become.
    Kohl: You were right to fear me.
  • Jumped at the Call: Kohl went from being a Berlin Wall sentry to spy when his country needed him.
  • Roaring Rampage of Revenge: Against his former comrades in the Stasi, for collectively betraying him after having Heel Realizations.
  • Suicide by Cop: Variation. He makes like he's going to shoot somebody and Reese fatally shoots him, then it turns out the gun was empty.
  • Torture Technician: Tortures Reese for information, in a manner most technical.
  • Tragic Villain: Began to scare those around him due to his fanatical and bloody kill count, so they betrayed him when they defected. He wasn't pleased and flew to New York to get even—but then he meets the wife he thought was dead, and his daughter who he never met and then after realizing what he's become when his wife tells him she's utterly terrified by him, gets Reese to shoot him, killing him.
  • Underestimating Badassery: Kohl seized his chance to escape when the German government, believing him to be old and feeble, transferred him to a minimum security prison.
  • Worthy Opponent: Kohl has a great deal of respect for Reese as a professional killer, even apologizing before trying to shoot him. This also plays into his Suicide by Cop; he knew that Reese would not hesitate to shoot a gunman if lives were on the line.

Henry L. Peck
Played by: Jacob Pitts
Appeared in: "No Good Deed", ".exe"

"Oh, my God, they actually built it. After 9/11, the government wanted a computer system — a machine — That could watch everyone and everything, catch terrorists before they strike. They tried with Trailblazer, TIA, Stellar Wind. They, they all failed. If I'm right, then someone really built the damned thing... and it's watching us right now."

A former employee of the NSA, who, over the course of his own investigation of additions to a number of his reports, realized that the government had built the Machine.

  • Explain, Explain... Oh, Crap!: After he's arrested, he comes to his Cassandra Truth conclusion as he thinks out loud:
    Peck: Someone was sneaking just as much data out as the NSA was taking in. To scan through all that, you'd need an organization ten times our size. It's more than any human— [Machine-POV of Peck looking suspiciously up at the interrogation room's security camera] Oh my God, they actually built it...

  • Drowning My Sorrows: She parties hard and gets drunk as a way to escape the reality of her mother's death.

"There's a rumor about this guy. The police just call him The Man in the Suit. No one's seen his face, no one knows his name, I'm not even sure he exists, but he's like something out of a comic book. When people are in trouble, he comes out of nowhere. He always seems to be there just in time. Whoever he is, he saves a lot of lives...and shoots a lot of kneecaps."

A journalist working for the New York Journal.

  • Break the Haughty: She published a story without fully confirming the facts because she wanted the big scoop. She ended up unintentionally getting a crucial (and innocent) FBI informant killed.

  • Deadly Nosebleed: One of the symptoms of his illness.

  • Nerves of Steel: One of the more calm POI's Team Machine has dealt with who doesn't lose his nerve or do something idiotic when his shipmate is kidnapped.

Appeared in: "Nothing To Hide"

An internet entrepreneur and data broker. He founded and served as CEO of Lifetrace, Inc, a business collecting and disseminating for profit the private habits and details of internet users, sometimes with dire consequences for the individual.

  • Asshole Victim: Big time, he's ruined many people lives and never made any effort to correct the problems with his website.
  • Break the Haughty: At the start of the episode, Kruger arrogantly claimed that people who wanted privacy probably had something to hide when they complained about his site. Peter Collier and a group of people who had their lives ruined by Life Trace proceed to take him down several notches.
  • Bitch in Sheep's Clothing: Presents a slick and charismatic personality but it's a lie. He's got a criminal record, gone bankrupt in a previous business, only cares about his financial success, has been having an affair and is willing to injure the man who's trying to keep him alive just for a chance at finalising the business deal he's been conducting. Collier is utterly disgusted by him that he convinced his superiors who wanted Kruger to be scared away from his company to instead accept his proposal to execute Kruger.
  • Corrupt Corporate Executive: Even Finch sees it and notes that he built The Machine as a Black Box so that men like Kruger couldn't abuse it the same way Kruger's website is abused.
  • Death Equals Redemption: Averted. Began to show authentic remorse when he learned that his site ended up killing someone. But he gets killed before he can make any possible attempt at redemption.
  • Evil Counterpart: To Nathan and Finch in that he also created a system that violates privacy. Unlike the two of them, who built it as a black box that could not be accessed directly and sold it for a single dollar, he was only interested in making a profit and failed to care at all for the privacy of those he monitored.
  • Hate Sink: Can you tell by his other entries that he is quite despicable in almost every way you can think of?
  • Hypocrite: Calls out Finch twice for reading his personal info.
  • It's All About Me: Only cares about himself and getting the business deal with his website finalised. Made more apparent when he smashes a vase on Harold's head and heads to a business meeting where he believes the deal can be finished. It's a trap for Collier to kill him.
  • Jerkass: Taken up to eleven when he smashes a vase on poor Harold's head.
  • Large Ham: Given that the actor is theatrically trained, when Kruger starts losing it, he really starts losing it. It actually makes a couple of his scenes somewhat amusing in spite of his Hate Sink status.
  • Laser-Guided Karma: Peter Collier arranges for him to suffer a severe loss of privacy and ruin his life in the same way Kruger's site did to so many others.
  • My God, What Have I Done?: After the father of a girl who's stalker/murderer used Life Trace spells out how Kruger's inaction when he requested sensitive information be removed was ignored contributed to her death, Kruger shows genuine remorse for the first time in the episode. Collier is not impressed however and shoots him.
  • Never My Fault: His main flaw, he never accepts responsibility for how his website helped destroy so many lives. One of the people who lost his child to a stalker who was using Life Trace to track her pointed out that he did nothing and didn't listen to the requests to pull critical information from the site.
  • The Sociopath: Only just barely subverts this, since he actually does show remorse after learning about his role in the death of a man's daughter. But most other sociopathic traits are still present in his demeanor, including self-centeredness, focus on profiting from his site, and refusing to acknowledge mistakes.
  • Trauma Conga Line: For the first time, in the history of the show, its actually quite deserved. He's revealed to be having an affair at his wedding anniversary, his secretary learns he only hired her for her looks, the potential business partner leaves him out to dry, the board of his company learns about his shady criminal and business history, he gets thrown out of his company, he's nearly killed in a falling elevator,then a car accident and finally, he goes to what he thinks is a business meeting but is in fact a trap to kill him.

"I said we should scare the bastard, but Collier convinced the group that it was time for more... aggressive action. I'm not a killer."

The foster brother of Timothy Sloan, and a computer hacker marked for death by Vigilance. Notable for being the first Number assigned to Root by The Machine ("There's a third category.") to appear on the show.

  • Everyone Has Standards: He suggested that Vigilance target Wayne Kruger, but only wanted to scare him. When Peter Collier decided to kill him instead, he decided to walk. This is likely part of why The Machine wanted Root to recruit him for her team.
  • He Knows Too Much: The reason he's targeted for assassination.
  • Not Quite Dead: Jason was believed dead due to a drug overdose, but his death was actually faked to keep him safe from Vigilance.
  • Put on a Bus: Sent away to safety by The Machine after being rescued. He later returns to help prep the "blind spot" Samaritan servers so that they will not automatically be found when it comes online. He then gets sent away to safety again.

A former software engineer for the NSA, and an old friend of Harold Finch and Nathan Ingram back from when the trio attended MIT together. He also suffers from memory loss due to a brain tumor.

  • Crazy-Prepared: Apparently, he hid the drives of Project Samaritan after the government shut it down.
  • From Bad to Worse: He goes from having such bad memory loss that he forgets his own wife, to being attacked by privacy terrorists, to being held at gunpoint by the woman acting as his wife.
  • Obfuscating Stupidity: Not all of his memory lapses are genuine. At one point, he "played the tumor card" to stall for time when he and Harold are being held at gunpoint.
  • Properly Paranoid: There's a good reason that he doesn't trust his wife...
  • Unknown Rival: To Finch; he was also trying to create an Artificial Intelligence defense system after 9/11. Not only that, he succeeded. He'd just finished raising Samaritan to self-awareness when the success of Finch's Machine caused his program to be shut down.
  • Walking Spoiler: Being the creator of Samaritan, it's hard to talk about him without giving a lot away.

"Managed to get a few bits of code onto the laptop before the system woke up and bit me. It adapted to my hack. Locked me out. ... It's so advanced it's almost alien."

A freelance hacker who specializes in testing the security of computer systems. He worked for many years as a part of various tiger teams.

  • The Cracker: He's a professional computer hacker, and the fact that he was able to find Ingram's backdoor in The Machine (and was unwilling to tell the government about it) gets him marked for recruitment by Root.
  • He Knows Too Much: Casey is aware of the Machine's existence, and for that he's chosen for assassination.
  • Properly Paranoid: He's very suspicious of most people, and he's right to be. Most everyone wants him dead.

Played by: Nestor Carbonell
Appeared in: "Most Likely To ..."

"For two decades, I believed I pushed Claire over the edge, that she OD'd because of me, until I got this reunion invitation and I started thinking like a prosecutor instead of a boyfriend. You want justice? I served a guilty sentence the last 20 years. Shooting you and letting you rot for the next 20, I mean, that sounds like justice to me."

A prosecutor and former student of East Springs High School.

  • Amazon Chaser: Reed is very attracted to Shaw.
  • Clear My Name: He seeks to do this by murdering the person actually responsible and leaving a forged suicide note. (See quote above.)
  • Convicted by Public Opinion: He was never actually found guilty of murdering his prom date, but all his classmates suspect him and basically consider him guilty since the real culprit wasn't caught.

  • Reunion Revenge: With a side of Prophecy Twist: Reese and Shaw think he is going to be on the receiving end when the truth is the opposite.

Oh, and he's helping kickstart a surveillance state.
  • Ignored Epiphany: He almost has a moment of doubt on his face after ensuring that legislation on Samaritan passes committee, but he ultimately brushes it off.
  • Manipulative Bastard: He's a social wizard, able to navigate almost any situation to his benefit. In one of his first scenes, he manages to get an angry union leader to agree with how he screwed them over and then pass off tickets to an opera he despised onto said leader.
  • My Country, Right or Wrong: Subverted. He's fully aware that the government has major flaws. Its how he justifies being paid off to put government feeds in corporate hands.
  • Small Role, Big Impact: A single episode PoI. His survival ensures that Samaritan comes online.

  • He Knows Too Much: Samaritan targets and ultimately kills him for this reason.
  • Humiliation Conga: His existence is systematically dismantled by Samaritan; his life is destroyed, his reputation ruined, everyone abandons him, and he's ultimately killed.
  • Insufferable Genius: He's a remarkably intelligent man, but also arrogant: few people in his own company actually like him or even feel sympathy for him. It isn't hard to understand why people are willing to oust him from his company, since he doesn't seem like the kind of person that's easy to work with.
  • Properly Paranoid: Khan thinks an artificial intelligence is targeting him, and he's absolutely right.
