JC Denton

Aside Adam Jensen from prequels, he's the most iconic character in the game. He's stoic, expressionless, no bullshit character. But because of his nature of being a blank slate character, his tone is neutral at best, his actions and what he says often depends on the player's actions and dialogue options. He's blatantly ripping off Blade and says cheesy one liners.

Paul Denton

He's an older brother of JC. Unlike JC, he expresses his emotions more clearly and rips off Neo instead. Unlike most of the UNATCO agents, he's a bit more pacifistic, encourages JC (as well as others UNATCO troops) to at least try using non-lethal approaches and thinks more critically, hence he was disappointed in UNATCO's ways of dealing with terrorists and betrayed UNATCO.

Gunther Hermann

He's a bulky goober that believes in UNATCO. He's quit his job as a cop for his vigilantism, as he wanted to seek justice. While his approaches are lethal, he's not a psychotic maniac, unlike his partner in field Anna Navarre, and is more human. He enjoys his orange soda (haha, german likes Fanta) and has been asking for a skull gun for 20+ years (unless for some reason, prequels are not canon for you). Since he's a foreigner (German), he speaks with an accent and his grammar is bad.

Alex Jacobson

He's a nerd with two keyboards on his pants. He's more kind hearted and knows a bunch about computers, as he installed a pretty strong security for UNATCO and communicates with agents through InfoLink. In his office you can see a bunch of soda laying around (and I'm sure he would've had a bunch of pizza as well). He trusts JC a lot and is ready to quit UNATCO to help him, and doesn't really like the way some agents operate. Also he looks kinda like Texas-based techno cryptid John Carmack

Jordan Shea

She's an augmented ex-UNATCO agent (technically on extended leave) that works as a bartender in Hell's Kitchen. She likes her job and will do anything to keep the bar running and peaceful. She's involved with a local community and wouldn't really snitch on people that much (unless there's a martial law or some smooth talkers).

Adept 34501

She's a MJ12 agent, a WIB. She's a very minor character, but what makes her distinct from other People in Black, is that she feels bad for her given name being replaced by MJ12 with a generic string of numbers and that she feels pity for Gunther. Basically, she still has some humanity in her, despite all the physiopharmaceutical augmentation she has.

Morpheus

Morpheus is a prototype for Echelon IV (which became Daedalus). Blah blah blah, add some text.

Helios

Helios is a result of Daedalus and Icarus AIs merging together. Blah blah blah, add some text.

Walton Simons

He's one of the antagonists of Deus Ex, blah blah blah, add some text.

Smuggler

Howard Strong

Vinny

Jock

two bums from clinic

Isaac

He's a minor character that appears in Lucky Money club. He's an aussie and works as a bartender. Blah blah blah, add some text.

Tracer Tong

Nicolette DuClare

Bob Page

Add more minor, but "soul" characters
