The player character. Aiden Pearce was born in Belfast, Northern Ireland on May 2, 1974 at the height of the Troubles. He is no stranger to violence and is more than willing to use it against his enemies. However, his actions have had an untoward effect on his family, and now he monitors them in secret in order to keep them safe.
Anti-Hero: Depending on how you play. Pearce himself is definitely not a saint. Most of the time he is an Unscrupulous Hero who is willing to steal, kill and cause wanton destruction to achieve his ends. But depending on player actions, he can easily sink down to a Nominal Hero.
Awesome McCoolname: Aiden, which is Gaelic for 'fire'. And Pearce because it just makes you sound intimidating.
Badass: With nothing but hacking skills, a feel of parkour, a sense of justice and sheer determination, Aiden takes on a system that watches everybody by its own terms.
Badass Biker: Pre-release trailers and screenshots have often showed Aiden on a bike.
Badass Driver: His skills behind the wheel, along with a penchant for stealth driving brings the Driver to mind. In fact, some of the contracts Aiden can take are transporter and getaway jobs.
Pearce: "I wasn't always this guy. They crossed the line, and now I'll make them pay." Pearce: "... That's when they came for me. But killed her. Now, I'm coming for them."
Bullet Time: The game use this to represent Aiden's reflexes.
Coat, Hat, Mask: Mostly. Aiden looks normal enough when pretending to just be going about his business, but when he's about to do something overtly illegal, he pulls his neck gaiter up to cover his face. This screws up ctOS's facial recognition.
Lightning Bruiser: Aiden is a big guy, and his street fighting skills show him to be quick and brutal.
This is pretty much what sets him apart from the other main hackers of the game. Unlike Defalt and Damien and to a lesser extent T-Bone, Aiden is very good at both hacking computers and hacking people.
Heel-Face Turn: She used to provide information to the Chicago South Club, even locating the names of people they wanted dead, until the hit on Aiden killed Lena. She cut ties with them after this and worked with Aiden to make up for her past.
The Illegal: Her immigration visa has expired, but she (obviously) has stayed in the United States illegally.
Tattooed Crook: Has a rather prominent Illuminati-looking tattoo on her chest.
Voiced by: Aaron Douglas
"When youíre screwed beyond belief, you call in a fixer. And thatís Jordi. He gets things done and gets paid good money for his services. You need a body to disappear? You gotta find a missing adversary? Someone pissed you off? You call Jordi."
A man who does dirty work for money. He has no recorded profile on ctOS.
Anti-Hero: Appears to fall squarely into this trope.
Jordi: Okay we've got a bunch of dead bodies, right? We've got 40,000 people above us— We need a distraction. I called the cops.
Consummate Professional: Laughably Evil traits aside, he takes his work overall seriously & dedicated to his professional reputation as well as seeing jobs through perfectly, no matter who his client is or who it puts him against. The only exception is going into Rossi-Fremont, which he refuses to do for Aiden (though sniping from outside is okay), but he only says it's because he doesn't pay him enough to do so.
Laughably Evil: He might be on Aiden's side for the most part, but he's still very amoral, even immoral. However, the way he acts about his immoral acts is so entertaining that its sometimes hard to think badly of him.
Token Evil Teammate: Aiden considers him "the devil I know" and even notes that under other circumstances, the two would likely be against one another. And they do wind up against one another for short time near the end.
Wild Card: Perfectly willing to go up against Aiden near the end since the contract called upon it. Once their short exchange is over and he fails, he contacts Aiden, checks on his status, and goes back to immediately settling his remaining work with Aiden at that point.
Theodore "T-Bone" Grady / Raymond Kenney
Voiced by: John Tench
"T-Bone grew up a tinkerer and a basement hacker before the Internet was barely a byte. He canít help challenging his mind to unlock areas forbidden to him. And it hasnít gone without punishment. But heíll take his jabs. And heíll give his share in return."
A hacker hiding out in Pawnee whom Aiden meets while looking for Raymond Kenney. He is really Raymond Kenney, the creator of ctOS and the one who caused the Northeast Blackout of 2003.
Badass: Manages to defeat Aiden in a one-on-one fight, although he did get him drunk first. He later helps Aiden fight off an attack on his compound.
Southern-Fried Genius: Well, for starters, he's pretty clever to have built all those contraptions. Including ctOS.
The Stool Pigeon: Of the whistleblower variety. He tried warning people about what Blume was up to, but was discredited and dismissed as mentally ill and paranoid.
Stuff Blowing Up: He has a quite a few explosive traps around his junkyard. Later he blows the whole thing up after Blume discovered his location — but not before taking a picture "for [his] portfolio".
Unperson: He has Aiden break into a Blume station in Pawnee to plant a virus that will wipe his biometrics off of the ctOS servers, otherwise he'd be spotted soon as he sets foot in Chicago.
Unwitting Instigator of Doom: In his backstory. He's the hacker in the game's plot who caused the Northeast Blackout of 2003, which prompted the creation of ctOS's mainframe and further development in the first place.
Wrench Whack: In his DLC, he uses a wrench as his melee weapon.
Ax-Crazy: Caves one of his men's skull in with a heavy briefcase over Quinn calling him a weasel on the phone.
Berserk Button: Implied to be when other people think he is stupid or manipulable (as this is a deliberate act of Obfuscating Stupidity on his part), as one of his mooks finds out shortly after he is introduced.
Big Bad Wannabe: Though he is legitimately threatening and is half of the reason why Quinn put out the hit, the real top dogs in the criminal world keep him in line. Lampshaded by Aiden during their confrontation.
Boss In Mooks Clothing: He's classified by the enemy-tagging system as an Enforcer, but he's immune to melee takedowns.
Climax Boss: Fought at the very middle of the game, atop his HQ. Also serves as the only direct Boss Battle in the game.
Disc One Final Boss: He is the major threat for the first half of the game, and the quest to hijack his server drives half the plot.
The Dragon: To Lucky Quinn, providing him extra muscle and security.
Evil Laugh: He has a particular high-pitched laugh that he only uses when he's terribly, murderously angry.
Gang Bangers: Is the leader of the Black Viceroys. Only the low level members of the gang operate like the trope though. Most of the higher-ups have been given military training by Iraq and have equipment way beyond what a street gang should. The low level operations are just a show to fool anyone watching from suspecting what the Black Viceroys really are.
Genius Bruiser: Given his status as a gang leader & physical elements, you'd generally take him as just being a muscle. Beneath that however is an intelligent foe who values technology, introduced all sorts of military training techniques into his men, and is a skilled hacker.
Hidden Depths: Despite all he is, his personal information reveals he was discharged from the army with honors.
Lame Comeback: His only reaction to being told he's Lucky Quinn's lapdog is "Fuck you".
Pet the Dog: Despite his threats, he doesn't execute Bedbug after finding him in his server room while wearing a wire.
The Starscream: He doesn't plan on staying second to Quinn for long, and has been gathering extensive blackmail materials on pretty much everyone important in the city to use when he is ready to make his move.
Villainous Breakdown: After Aiden storms his compound, steals his blackmail, and practically wipes out his entire gang single-handedly, he starts ranting and raving about how he is going to destroy everything Aiden has for trying to take his blackmail and destroying so much of his gang.
Visionary Villain: You have to hand it to Iraq: he's transformed a street gang into what is essentially a highly trained private army, and has spread his influence throughout Chicago and could legitimately be able to take over if given the opportunity. Even Jordi is terrified of his gang.
Even Evil Has Loved Ones: He loves his grandma, and the only reason he doesn't flee Chicago after Aiden blackmails him is because he doesn't want to leave her alone.
Fat Idiot: Aside from not being book smart (see Comically Missing the Point for instance), he also talks about his tendencies toward The Starscream in broad daylight without even bothering to hide it unless directly in front of Iraq. It's a wonder he wasn't caught out on blackmail before Aiden comes along.
The Mole: Aiden uses him to get into Iraq's server room. Of course, he gets found out.
Ax-Crazy: The whole plot is because he wouldn't walk from a ATM hacking scam on account of a growing god complex. When he starts "working with" Aiden, he's unstable and unreliable enough that the latter is almost always trying to get out of the arrangement as soon as possible.
Big Bad: His kidnapping of Nicky and attempts to seize control of ctOS drive half the game's plot.
Irony: For the man who taught Aiden his social engineering skills (in addition to hacking), he himself is kind of a complete dick to him, and obviously not to be trusted.
Jerkass: Is frequently snide and condescending towards Aiden in their interactions with each other.
Villainous Breakdown: Starts his breakdown in Act 2 when it becomes clear that Aiden refuses to follow commands. After acting like a Smug Snake for much of the game, Damien finally loses it when Aiden leaks Iraq's blackmail data to the public rather than handing it over to Damien. This prompts Damien to hijack ctOS in an attempt to kill Aiden.
Voiced by: Christopher Jacot
The thug who was ordered to carry the hit on Aiden.
Death Seeker: At the end of the game during the credits, there's one last choice for Aiden to make: kill Maurice or let him live, even while he's begging Aiden to kill him.
Omniscient Council of Vagueness: The QR logs you find show that the leaders are said to have the name Dave in their screen names, meaning they could be anyone not just in Chicago, but in the world.
Voice Filter: The spokesman for Ded Sec speaks with a deepened voice to mask their true identity.
We Wait: How they take action to Clara giving Aiden their control of ctOS.
JB "Defalt" Marcowicz
A hacker who has just as much access into the ctOS as Aiden.
Cool Car: His Rosewood. It's pretty much a suped-up station wagon that has LED lights showing his insignia taking up the back windows. The fact that what is effectively a station wagon is classified as a performance vehiclenote And is, statistically-speaking, one of the best cars in the game tells you all you need to know.
Dangerously Genre Savvy: The first thing Defalt does when he goes up against Aiden? Dig up as much dirt on him as possible, including everything about the hit that got his niece killed. Then when he hacks into Aiden's system, he reveals that Clara was involved in that hit. Not only does this destroy their team trust, but he uses it as a distraction while he steals all the data that Aiden worked so hard to get from Iraq.
E-mail from Defalt: Subject: "why Defalt will always win..."; Message: "because Defalt sees the future, pearce is too busy looking at the past"
Oh Crap: Defalt's reaction to the ease with which Aiden deals with the fixers he sends after him. See Worthy Opponent below for details on how he reacts to this.
Silent Bob: Never actually speaks except through text messages.
Subverted in the Bad Blood DLC where he talks with a voice distortion.
Playful Hacker: A bit too playful. And not nearly as funny when he's doing it to you.
Psychopathic Manchild: Picture a particularly annoying Troll in your online game of choice, the kind who constantly trash talks you and spews leet speak like a broken faucet, and you have a rough approximation of what dealing with Defalt is like.
Punch Clock Villain: Like Jordi, there's nothing indicating that Defalt has any beef with Aiden. The only reason he bothers Aiden at all is because he was hired by Quinn after Clara wanted nothing more to do with him.
Villain Cred: Clara and T-Bone both note how good of a hacker Defalt is, to the point where he can send messages to Aiden through others' phones and mess with their ctOS profiles for the same reason, and Aiden is legitimately impressed by his firewall designs.
Worthy Opponent: Defalt is surprised at how easily Aiden deals with the Fixers and is eager to engage in a game of Dueling Hackers with him. The feeling is mutual to some degree.
