Main characters

Rex Salazar

* Voice Actor: Daryl Sabara
:Rex Salazar is a fifteen-year-old (sixteen in Season 3 due to six-month time skip) half-Argentinean, half-Mexican, human 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 even cure other E.V.O.s of their mutations and use his nanites to create a variety of machines on his body and communicate with various technology as well as manipulate and control it to his will. Upon being injected with the specialized Omega Nanite, he developed the ability to create even stronger and more effective machinery, each possessing their own unique properties. He also became strong enough to cure animals of their tainted nanites, and detect the presence of the four-armed, portal-creating E.V.O. Breach. Despite being a ladies' man,his one-and-only girlfriend is a fellow human-looking siren-like E.V.O. named Circe who originally worked for his archenemy, but ultimately defected when she came to realize that Van Kleiss only desired Rex "alive" in body only. She then has joined his E.V.O. gang in Hong Kong, China.
:According to his archenemy, Van Kleiss, he has inherited his late Mexican mother Violetta's headstrong nature.

:About six months into the future from Breach's newfound time-traveling ability, Rex is working against Providence's new boss, the power-mad Black Knight, to stop her and the Consortium from attaining infinite and boundless godhood from the merger five specialized nanites called "Meta Nanites" ("Master-Control Nanites") which only he alone could fully control in their purest state, as his late parents had secretly programmed just for him. He is now dating his very first girlfriend Circe, as their romantic relationship was fully revealed to be genuine in "Assault on Abysus", although fans quite disappointed there were not enough episodes for the couple to have many moments together long before the events of the two-part finale. Since then, he is now in a fully blossomed romance with Circe.

Agent Six

* Voice Actor: Wally Kurth

Agent Six is a senior Providence agent and Rex's handler. His name came from the fact that he is the sixth most dangerous person in the planet. Owing to Six's strict by-the-book personality, Rex goes as far as to refer to him as a "nanny, just more aggro." He always wears a green suit with a black tie and black sunglasses. As noted, Six likes to continually wear the same suit. It was shown that Six had brown eyes. He came to fall for Dr. Rebecca Holiday, confessing his feelings for her in "A Family Holiday" and seemed to regain them regardless losing six years of his memory in "Six Minus Six."

Bobo Haha

* Voice Actor: John DiMaggio

Bobo Haha is an E.V.O. chimp with the ability to speak. He is also Rex's sidekick and friend. He wears an eye patch and fez.

Bobo also claimed that before he was turned into an E.V.O., he was a helper animal trained to entertain children at a hospital. His owner was supposedly an eccentric philanthropist.

Dr. Rebecca Holiday

* Voice Actress: Grey DeLisle
Dr. Rebecca Holiday is the lead scientist for Providence, a position she earned due to her expertise in nanotechnology. Along with Agent Six, she is responsible for taking care of Rex and takes her job very seriously, constantly monitoring Rex to ensure his safety. She also harbors a crush on Six, which he eventually grows to reciprocate in "A Family Holiday" and starts to recall said feelings in "Riddle of the Sphinx" since losing his memories in "Si Minus Six."

Noah Nixon

* Voice Actor: Fred Savage

Noah Nixon is a normal human and Rex Salazar's best friend. In the beginning it was revealed that he is an agent sent by White Knight to befriend Rex and subtly influence his decisions to make him more compliant. Noah eventually revealed to Rex his status as a covert agent and they became friends on open terms. His girlfriend is his high school classmate Claire Bowman.

White Knight

* Voice Actor: J. K. Simmons

White Knight is the leader of Providence. He also is the only known nanite-free being on the planet: he almost always stays in his white sterile office, communicating his orders only through two-way screens. He has a Mysophobia-like fear of nanites, he doesn't want to touch or even be near E.V.O.s because he fears they will infect him with nanites, and therefore has donned a nanite-free battle suit that he constantly wears in the third and last season. In the five years after the Event, he had short pale brown hair and was a skilled agent for Providence working under Dr. Fell and was the closest partner of Six.

Antagonists

Van Kleiss

* Voice Actor: Troy Baker
:Van Kleiss is the primary antagonist of the show, a British scientist who specializes in biointerface and biomechanical integration. Van Kleiss appears to know about Rex and his forgotten boyhood past, and knows what caused the nanite incident five years prior was Rex's own teenage older brother Cesar. He saw the Nanite Event as the dawn of a new golden age for further evolved humankind, and seeks to create a planet populated solely by E.V.O.s. regardless of their weakness or frailties. Like Rex, he is able to control his nanites, but his mutation is quite unstable and requires a constant supply of fresh nanites for survival by extracting them from fellow E.V.O.s., who are petrified in the process. Upon acquiring Rex's batch of fully programmed original nanites, he gained the opposing ability to actually ''create'' E.V.O.s and have them under his control; a mutation which becomes permanent if not cured by Rex in less than an hour. This newfound ability of his only lasted since "Payback" and the entirety of the nineteen-episode second season.

:Since further increasing Breach's portal-making ability from the amp pack he himself had made for her, who had suddenly sent him back into the ancient past, Van Kleiss had endured the primitive eras of Egypt, and met Emperor Septimus Severus of Ancient Rome. Managing to create an Egyptian E.V.O. called G'raan Set in a makeshift laboratory, he then preserved himself in a hibernation chamber that stored his ever decreasing unstable nanties and ensured that he was able to remain alive as the present timeline passed, leaving him with a full-blown beard and mustache. He had then expressed insanity to mask his equally evil and ambitious nature until he could absorb the five Meta Nanites into. Having planned to attain godly abilities since the very beginning, it was he who had caused the deaths of Cesar and Rex's parents, Rafael and Violetta, by trapping them inside as the nanite reactor exploded. Having failed, his golden gauntlet was destroyed and he was taken to Breach's pocket dimension of Greenville, Ohio.

The Pack

The Pack is a group of E.V.O.s that serve under the British E.v.o. scientist Van Kleiss. Its known members include the following:

Biowulf

* Voice Actor: Troy Baker

Biowulf is a blue-armored, white-haired, werewolf-like E.V.O. with enormous claws, who is fiercely loyal to Van Kleiss, whom he calls "master." Owing to Van Kleiss' powers being limited to his native soil in early episodes, Biowulf initially acts as the Pack's de facto leader in the field.

Skalamander

* Voice Actor: John DiMaggio
Skalamander is a large humanoid lizard-like E.V.O. with crystal spikes growing out of his body, four short stubby legs and a crystal club growing out of his left arm.

ZAG-RS

* Voice Actress: Grey DeLisle

ZAG-RS is a sentient and autonomous, self-aware artificial intelligence/multi-agent system whose goal is to destroy the nanite infestation of Earth, thus all of humanity in the process. Its origin and motives are initially left mysterious, but it is able to exert control over the nanites at very short ranges. It made several different attempts to achieve its goal but was thwarted both every time by Rex. Its feminine voice was modeled after the deceased Mexican scientist Dr. Violetta Salazar's, as its inventor (the-then-teenage Dr. Cesar Salazar) had wanted it to have a voice that represented safety, protection and caring; all the feelings of a loving mother.

Agent Weaver

* Voice Actor: Troy Baker

Agent Weaver is a former member of Providence stationed at the arctic "Paradise" base where he was the chief technician. He and his crew were revealed to be traitors who were reactivating and selling nanites to Van Kleiss.

Hunter Cain

* Voice Actor: John Cena (1st Time), John DiMaggio (2nd Time)

Hunter Cain is an E.V.O. hunter who despises ''all'' E.V.O.s under all circumstances as he went insane after his wife became E.V.O.

NoFace

* Voice Actor: Fred Tatasciore

NoFace is a supremely powerful and vengeful faceless E.V.O. with the ability to communicate with intelligent E.V.O.s and control the less intelligent ones. During the nanite event, the Gulf Stream funneled a huge amount of active nanites into the city of Kyiv, Ukraine, transforming nearly all that lived there into extremely powerful E.V.O.s. Among them was their current leader, NoFace.

Quarry

* Voice Actor: Mark Hamill (1st Time), John DiMaggio (2nd Time)

Quarry is an E.V.O. crime lord who is made of rock. He would hunt down and force E.V.O.s like Tuck, Skwydd, and Cricket to work for him through having gathered a massive criminal empire. In "Rabble", he learned of Rex's return from his enforcer Knuckles after Rex drained him of his nanites. Quarry had to dispose of Knuckles after that. He reappeared in "Hard Target" when he was released by Breach, but ended up being taken to Abysus and tortured extensively by an unhappy Van Kleiss. His final appearance is in Episode 52 "Remote Control" when he had a larger appearance due to what Van Kleiss had done to him, and mind-controlled Sqwydd, Tuck and Cricket to attack Rex once again. He was ultimately beaten by Rex and had his whole stone body blown apart, leaving only his head and fate known.

Gatlocke

* Voice Actor: Greg Ellis
He is a British cyborg who is a leader of a group of modern-day pirates known as "The Anarchists" who debuted in Episode 20 "Badlands." He eventually makes his second and last appearance in Episode 59 "Enemies Mine" to take out Rex once and for all by aligning himself with Hunter Cain, NoFace and Valve whose fates are unknown since they were trapped inside a shield that was made by Rex's surplus nanites at Purgatory Base.

Black Knight

* Voice Actress: Jennifer Hale

Black Knight is the next Providence leader after White Knight rebelled against his superiors in the Consortium. When she took over Providence, she started to run things very differently from the way White Knight had. She believes in controlling the incurable E.V.O.s as rather than trying to cure them, Rex in particular. She secretly attempts to become a almighty goddess by attaining all five Meta Nanites for herself, even turning on her own superiors. She is eventually captured off screen.

Valve

* Voice Actor: Maurice LaMarche

Valve is a samurai-styled biker and a dealer of an altered form of nanites which can link a person to technology. He eventually makes his second and last appearance was in Episode 59 "Enemies Mine" to take out Rex once and for all by aligning himself with Hunter Cain, NoFace and Gatlocke whose fates are unknown since they were trapped inside a shield that was made by Rex's surplus nanites at Purgatory Base.

Gharun Set

* Voice Actor: Hakeem Kae-Kazim
:Technically the very first E.V.O. ever created, Gharun Set was an ancient Egyptian created by British scientist Van Kleiss when Breach sent him back in time to ancient Egypt. Somehow being able to create a nanite production chamber, what Set calls the "engines of life" Van Kleiss infused them into Gharun Set, changing his appearance into a dog-headed mummy-like humanoid with an eye in the center of his chest.

The Consortium

The Consortium is a powerful organization which supports Providence and are the superiors of Black Knight. Little is known about this organization, but they seem to provide funding for Providence and the Nanite Project. In six years, they had finally managed to merge with four of the five almighty Meta Nanites, turning into biomechanical robots with strong powers ranging from teleportation, pyrokinesis and cryokinesis, and electromagnetic-controlling abilities.

Reddick

* Voice Actor: Robin Atkin Downes

Xanubian

Xanubian is an African American arms dealer and shipping industry associate who is a member of the Consortium. When merged with a Meta-Nanite, he was transformed into a thin tall robot E.V.O with green armor and had the ability to manipulate time and space. Unlike the others, he is mute, although Roswell calls him a chatterbox.

Vostok

* Voice Actor: John DiMaggio

Vostok is a black market financier and KGB operative who is a member of the Consortium. He was with the Consortium when Black Knight brought about her plans to restart the Nanite project. Vostok had some doubts about Black Knight's plot causing Black Knight to kill him when they were alone. Black Knight told the other Consortium members that the enemy was responsible for Vostok's death.

Alpha

* Voice Actor: Michael Emerson

Alpha was created by Caesar to control other nanites as a sentient being, but its energy/nanite body was unsustainable. Alpha tried to make mechanical bodies to sustain itself and that failed, so instead it tried to use living organic bodies as hosts. It is equivalent to the immensely powerful Omega Nanite/fifth Meta Nanite harboring within Rex's body. He is ultimately taken back to the Null Void by Benjamin Tennyson (in the form of Upchuck) and escapes his metallic prison as the Omega Nanite is re-injected inside Rex.

Supporting characters

Diane Farrah

* Voice Actress: Grey DeLisle
Diane Farrah is a newswoman who hosts a news program called "Ultimate Exposure". She appears regularly at the places where Providence fights EV.O.s, as a hostess of her program or when she's having interviews with people involved with E.V.O.s.

Breach

* Voice Actress: Hynden Walch
:Breach is a four-armed human E.V.O. girl. Using her larger arms, Breach can tear open space and time, creating red wormholes; golden since her spacial-based abilities were boosted by Van Kleiss' amp pack. Her portals also seem to have a plane, as those who go through them can stand within the portal without having to step out on either of the linked locations. Her own personal place is Greenville, Ohio, which she had absorbed into a portal and keeps as her own dollhouse that keeps her sane. It was where she had taken Biowulf, Skalamander and Van Kleiss, so they could escape the infinitely powerful curing cosmic wave Rex had made.

Circe

* Voice Actress: Tara Sands
Circe is a dark-haired humanoid teenage E.V.O. with strong sound-based abilities and the ability to lure fellow E.V.O.s like to a siren's song, who debuted in the third episode, "Beyond the Sea", in which she and Rex began to feel a powerful connection form between them, though she still chose the Pack over staying with Rex, as she did not trust Providence's methods. She met up with Rex during her very first mission as Van Kleiss' loyal subordinate in "Leader of the Pack" where she had hesitantly knocked Rex unconscious and had him imprisoned, albeit with a sad expression on her face for resorting to hurt him to help her master. She was the only one who showed any real leniency towards Rex, and looked away from him in disappointment as she left with the Pack after her master's plan had failed.

A few weeks after the unexpected demise of Van Kleiss in "Dark Passage", in Episode 15 "What Lies Beneath", Circe had called Rex for his help in dealing with a crumbling Abysus due to her master's strong link with the unstable nanites being lost. When Rex learned that it was all about returning Van Kleiss to life, she had tried to reassure Rex that she needed him as much she needed Van Kleiss. She was concerned for Rex's safety when he rashly attempted to deal with the source head on, as it was causing him great pain. As she was about to be swept away the unstable nanites goop, she held onto Rex with tears of love in her eyes. After regaining consciousness in Rex's arms, she said that she was happy to see him. Thanking Rex for saving her life, she still refused to leave Van Kleiss, no matter how she cared for Rex, as it keeps things interesting.

Her second and final mission with the Pack was in the Bug Jar when she discovered, to her horror, that Van Kleiss was more interested in what Rex's body would give him, not caring in the least of what would happen to the boy's psyche. This was the final straw for Circe, enough that she left to join Rex's old friends in Hong Kong, China, where she seemed to have developed a close friendship with Sqywdd. This made Rex feel very uncomfortable and jealous until she assured him they were merely good friends on a strictly platonic level and nothing more. She and Cricket began to get out of any further "dates" by doing their hair and nails every weekend.

Half a year into the not-too-distant future, in "Assault on Abysus", she was asked to help bring Rex throughout Abysus to procure a Meta Nanite before Black Knight could, she had told Rex that there was nothing between them except the mission. In the end, however, she finally confessed her true romantic feelings for Rex in a passionate kiss before she got herself taken by New Providence for him, which affected Rex very much. In "Mind Games", her form was taken on by the shapeshifting E.V.O. John Scarecrow (a former partner-in-crime of Rex's) to mess with Rex's emotions. She was seen in a prison cell with a muzzle gagging her mouth.

Unfortunately the series had ended long before she and Rex's romance could be explored more fully in many more episodes before the events of "Endgame, Part 1", which disappoints fans greatly; she was in just nine episodes. In "Endgame, Part 2" once cured along with the rest of humanity, a glad and tearful Circe let a worried Rex hug her and put her arms around him; assuring him that she was "normal but okay" and jokingly saying that he had "put himself out of a job" by curing the world with his recently attained godly abilities from being one with all five Meta Nanites. It is confirmed that they are indeed dating as Rex continues to act as the planet's defender.

Claire Bowman

* Voice Actress: Danica McKellar
:Claire is a girl that Noah likes, as she is the most popular girl in high school. She is best friends with a supernaturally clumsy teenage girl name Annie. In her debut, "Operation: Wingman", Claire agreed to go to the prom with Noah only if he can find Annie a date. She appeared in "Haunted", in which she met Rex's elder brother Cesar and was impressed with his highly intelligent mind as a fellow scientist.

:In "Guy Vs. Guy", she was on another date with Noah while he and Rex were going all-out on a prank war that ended up endangering the entire city when Bobo Haha got involved. Some months later, in her final appearance in "Hermanos," she and Annie went with Noah and Rex to Argentina to see the ancestral ranch that Rex had inherited upon the death of his father Rafael, as a birthday present from Noah. She appeared only in four episodes.

Annie

* Voice Actress: Felicia Day
:Annie is a good friend of Claire Bowman. Owing to Annie's preternatural clumsiness, she had a difficult time finding a date for junior prom. Noah persuaded Rex to come to the prom as his "wingman" and take Annie out as well. Since then, Annie has doubled dated with Rex more than once, by the end of "Hermanos" Rex called that she, Claire, and Noah, are his true companions and he considered them as his family as much as Six, Bobo and Dr. Holiday were. She appeared only in three episodes.

Rex's Old E.V.O. Street Gang

This is an E.V.O. street gang that has lived in Hong Kong, China, since the Event.

* Voice Actor: Dante Basco
:Tuck is a red-eyed mummy-like E.V.O. who befriended a young Rex in Hong Kong, China, in the five years after the Nanite Event.

John Scarecrow at one point during their adventures of freedom. He appeared in just five episodes throughout the show.

Skwydd

* Voice Actor: Jason Marsden
:Skwydd (originally named Walter)is a humanoid squid E.V.O. who is seen to be pretty much of the serious type, giving Rex serious/obvious answers when Rex jokes around. Skwydd is shown to be rather moody and rarely smiles, something Rex jokes about. Skwydd has an interest in entertaining people as a freak show act.

:In "Hard Target", a deeply uncomfortable Rex had assumed that he and his siren-like sweetheart Circe were dating, but was quite relieved when he assured Rex that they were just friends and nothing more. He ended up being under Quarry's control once again by being collared by New Providence in "Remote Control" but is ultimately cured in "Endgame, Part 2" and goes by his real name "Walter" again; he had brown hair and eyes. He appeared in six episodes.

Cricket

* Voice Actress: Vyvan Pham
:Cricket, as her name states, is a cricket-like human E.V.O. who is the only female member of Rex's street gang at Hong Kong, China, during his younger years as a preteen. She becomes good friends with fellow human E.V.O. Circe, having another girl to "even out the boy-girl ratio" and do her hair and nails with every weekend. She appeared in just five episodes in the show; she was ultimately cured by Rex's nanite-powered godly abilities in "Endgame, Part 2."

Rex Salazar's Family

Dr. Rafael Salazar

Voice Actor: Carlos Alazraqui
:He was the Argentinean scientist father of Cesar and Rex from Buenos Aires, who had worked on the original Nanite Project five (six years ago in the third and last season) years ago with his Mexican wife, and their equally intelligent teenage son Cesar. He was tall, handsome, had a black mustache, black eyes and short back sleek hair. Once settling down in Geneva,Switzerland, he became a father to his youngest son Rex.

:About one decade later, he, his wife and teenage eldest son began work on the Nanite Project with fellow international scientists Dr. Gabriel Rylander, Dr. Peter Meecham and Van Kleiss, in Abysus, United States, at the behest of the Consortium. Unfortunately, he was ultimately killed alongside his dear wife due to the devious and ambitious Dr. Van Kleiss trapping him inside the exploding nanite reactor as the incomplete nanites scattered all across the Earth. His office is still intact, in which the ten-year-old Rex had drawn pictures and had, six years later as a teenager, recovered a photograph of his preteen self and his late father's hand on his shoulder. Cesar also has a picture of himself and a younger Rex with him as well, which was never shown.

:His family has a ranch in a rural area of his home country of Argentina, which his surviving sons inherit upon his death, as seen in Episode 55 "Hermanos." In the next six years, it had been under the legal guardianship of a large humanoid bull E.V.O.,by the name of Derango, until he was finally defeated by sixteen-year-old Rex and his good human friends Noah, Annie and Claire, which freed his farm and that of the fellow villagers from Derango's control. His middle name is not known.

Dr. Violetta Salazar

Voice Actor: Grey DLisle
:She was the late Mexican wife of fellow Latino scientist Dr. Rafael Salazar, she had eventually married him and bore him two sons, Cesar and Rex, whom she loved dearly. She was slim, with shoulder-length straight black hair, black eyes, and donned glasses. She was from Mexico City, Mexico, where she, her husband and sons had spent their summer at a local town run by a woman they considered as an '' abuela'' regardless of blood ties, where young Rex had befriended Frederico.She had traveled all over the world with her husband and teenage son Cesar, but had settled down once she had given birth to Rex in Geneva, Switzerland. At the family's ancestral rancho in Argentina (the home country of her husband), she had once held the video camera as her husband was telling a young Rex how the nanites would change the world for the better one day, and that he would be there to see it. She had told the teenage Cesar to stop his work for one moment and hold the camera for her.

:She had agreed to work on the Nanite Project with her husband and eldest son's help in Abysus, United States, alongside fellow scientists Dr. Gabriel Rylander (whom she had chosen to be Rex's godfather), Dr. Peter Meechum and Van Kleiss; the only female on the team who had donned glasses. Unfortunately, alongside her husband, she had instantly died from to being trapped inside the lab that harbored the unstable nanite reactor due to the devious and ambitious Van Kleiss locking her in, as the teenage Cesar, ten-year-old Rex, Dr. Meechum and Dr. Rylander had managed to escape the colossal explosion of the four-out-of-five Meta Nanites and hundreds of uncontrollable, overly underdeveloped nanites spreading throughout the world and bonded with human and animal physiology alike.

:Because she had been a motherly symbol of safety, caring and protection, her eldest son Cesar had modeled the autonomous artificial intelligence Zag-RS' voice from hers. According to Van Kleiss, she was quite headstrong, just like Rex. Unlike her husband, she appeared in less episodes as she is not seen in any pictures kept by her two surviving children; seen only as cameos in flashbacks about her working on the Nanite Project throughout the third and final season. Her middle name and maiden name remain unknown.

Dr. Cesar Salazar

* Voice Actor: Freddy Rodriguez
:He is Rex's long-lost Argentinian/Mexican older brother in his late twenties (who was in his middle or late teens during the Nanite Project five/six years prior) and one of the surviving scientists of the Nanite Project alongside Dr. Peter Meecham, Van Kleiss and Dr. Gabriel Rylander, who he managed to partially return to life as the old man had just been molecularity scattered. With his parents, he had secretly programmed the five Meta Nanites to obey no one but his younger brother alone, as the fifth and strongest was injected into fifteen-year-old Rex by Dr. Rylander (more conmanly known as "the Omega-One Nanite" since being injected into Rex in "Dark Passage") who had perished alongside Van Kleiss one year ago.

:For the next six months since his younger brother's sudden "disappearance", Cesar had cleverly kept his cover in giving the all-powerful God Code to Rex, even if it meant appearing as an enemy in his younger brother's eyes until it was revealed that he was merely playing along the Consortium and Black Knight's schemes for world domination in order for Rex to acquire the Meta Nanites unlimited godly abilities in full.

:He has a photograph of a ten-year-old Rex and his teenage self with their late Argentinian father, Rafael, which was never shown. He is starting to work on a brand-new project with Dr. Meechum and the still-incorporeal Dr. Rylander.
