Rex Salazar is a teenage (sixteen in Season 1) half-Argentinean, half-Mexican E.V.O born to a family of scientists. Unlike other E.V.O.s, Rex can control his nanites at will, allowing him to appear human and cure other E.V.O.s of their mutations. He can also use his nanites to create various machines on his body and communicate with and manipulate technology. After being injected with the specialized Omega Nanite, he gains the ability to create stronger and more effective machinery with unique properties. He also becomes strong enough to cure animals of nanites and detect Breach's presence. His girlfriend is a siren-like E.V.O. named Circe, who originally worked for Van Kleiss, but defected after realizing that he desired Rex "alive" in body only. She then joins his E.V.O. gang in

. According to Van Kleiss, he inherited his late mother Violetta's headstrong nature. After being sent six months into the future as a result of Breach's newfound time-traveling ability, Rex fights against Providence's new boss, the power-mad Black Knight, to stop her and the Consortium from attaining infinite godhood from the five nanites called "Meta Nanites" ("Master-Control Nanites"). He alone can fully control them in their purest state, as his late parents had secretly programmed them to fully work for him. He is now dating Circe, as their romantic relationship is revealed to be genuine in "Assault on Abysus". After the events of the finale, he enters a full romance with her, and is the only E.V.O. left to defend the world from further threats.

Agent Six

* Voiced by: Wally Kurth Agent Six is a senior Providence agent and Rex's handler, whose name comes from the fact he is the sixth most dangerous person on the planet. Because of his strict and by-the-book personality, Rex refers to him as a "nanny, just more aggro." He has brown eyes and wears a green suit with a black tie and black sunglasses. Over time, he falls in love with Dr. Rebecca Holiday, confessing his feelings for her in "A Family Holiday". Despite losing six years of his memory in "Six Minus Six.", he seemingly regains his feelings for her.

Bobo Haha

* Voiced by: John DiMaggio Bobo Haha is an E.V.O. chimp with the ability to speak, who is Rex's sidekick and friend. He wears an eye patch and fez.

Dr. Rebecca Holiday is the lead scientist for Providence and expert in nanotechnology. Along with Agent Six, she is responsible for taking care of Rex and takes her job seriously, acting as a surrogate mother for him.

She also harbors a crush on Six, which he grows to reciprocate in "A Family Holiday" and starts to recall in "Riddle of the Sphinx" after losing his memories in "Six Minus Six."

Noah Nixon

* Voiced by: Fred Savage Noah Nixon is a human and Rex's best friend. He is an agent sent by White Knight to befriend Rex and subtly influence his decisions to make him more compliant.

White Knight

* Voiced by: J. K. Simmons White Knight is the leader of Providence and the only known nanite-free being on the planet. He almost always stays in his office, communicating his orders through two-way screens. He has a Mysophobia-like fear of nanites, as he does not want to touch or be near E.V.O.s out of fear they will infect him with nanites. Because of this, in the third season he dons a nanite-free battle suit. In the five years after the Event, he had short pale brown hair and was a skilled agent for Providence working under Dr. Fell as well as Six's closest partner.

Like Rex, he is able to control his nanites, but his mutation is unstable and requires a constant supply of fresh nanites for survival by extracting them from other E.V.O.s., who are petrified in the process.

Its origin and motives are initially a mystery, but it is able to exert control over nanites at very short ranges. It makes several attempts to achieve its goal, but Rex stops it each time.

He reappears in "Hard Target", when Breach releases him, but he ends up being taken to Abysus and tortured by Van Kleiss.

A few weeks after the unexpected demise of Van Kleiss in "Dark Passage", in "What Lies Beneath", she calls Rex for his help in dealing with Abysus, as Van Kleiss's link with the unstable nanites was lost and is causing it to crumble. After Rex learns that she plans to return Van Kleiss to life, she tries to reassure him that she needs him as much she needs Van Kleiss. She is nearly swept away by the unstable nanite goop, but after being saved and regaining consciousness in Rex's arms, she says that she is happy to see him. Despite thanking him for saving her life, she refuses to leave Van Kleiss as it keeps things interesting. Her second and final mission with the Pack is in the Bug Jar when she discovers, to her horror, that Van Kleiss is more interested in what Rex's body would give him and does not care about what could happen to his psyche.

John Scarecrow, a former partner-in-crime of Rex, takes on her form to mess with Rex's emotions. In "Endgame, Part 2", after being cured along with the rest of humanity, she embraces Rex and assures him she is "normal but okay" and jokingly says he had "put himself out of a job" by curing the world.
