At the young age of ten, he was fatally hurt in an unspecified industrial accident. To save his life, his parents and older brother, Caesar, had infused him with the original batch of fully programmed, highly evolved nanites, which granted him several unique technopathic and mechanical abilities as side effects.

Recurring

• Noah Nixon: A non E.V.O. who has cropped blonde hair and pale blue-green eyes. He is Rex's first best friend who was initially working for White Knight to "keep an eye on Rex." He has a thing for Claire. Declared by Bobo Haha to be the King of Pranks, a champion table tennis player, and shoots a good hoop in basketball.
• Van Kleiss: The main villain of the series, and Rex's archenemy. Heavily tied to Rex's past he offers the promise of helping him gain some old memories if he joins him. Programmer for interface technology with the nanites, and can create EVOs. Last seen being taken by Breach presumably to her alternate demention.
• Biowulf: A biomechanical wolf-like E.V.O. who is the second-in-command of Van Kleiss' followers, the Pack.
• Breach: A young E.V.O. girl with four arms, pale white skin, and the ability to create red portals to any destination. Obsessed with Rex for his unique qualities, she once kidnapped him to put in a pocket dimension, where she has everything just as she likes it. Van Kleiss forces her into time travel technology, and an insurance protocol sends her scattered through time, and Rex helps her from his grasp, helping her to become her own person. It is unclear if he and Breach are friends, but they both hope for it.
• Skalamndar: A green lizard E.V.O. who is constantly drooling due to his head being on sideways that can project dozens of crystals from his arms, and form crystal walls.
• Caesar Salazar: The eccentric, slightly mad scientist and older brother of Rex. He was first referenced in "Dark Passage" by Dr. Gabriel Rylander. He arrives in a mobile lab back on the planet with time displacement five years after the nanite explosion and immediately goes to protect the Omega Nanite, and his little brother. Sometimes his priorities are vague to his little brother.

Supporting

• Circe: Rex's main love interest/girlfriend in the show. She is a human-looking E.V.O. with unusually strong powers over sound and certain types of songs which she uses to allure and summon fellow E.V.O.s to her. She finally admits her true romantic feelings for Rex, in the form of a passionate kiss, in "Assault on Abysus."
• Claire Bowman: A teenage student in high school with Noah, who has a crush on her. Highly intelligent in science.
• Annie: A good friend of Claire's who possesses supernatural clumsiness. Almost killed Rex on prom night.
• Tuck: An old companion of Rex and his old street gang who reside in Hong Kong, China. He is a mummy-like E.V.O. who can elongate his limbs. When Rex chases Breach to Hong Kong, he recognizes a blossoming romance between Tuck and Cricket before they realize it, and while they say they are only friends, as Rex leaves, Tuck and Skwydd chase down Circe and Cricket attempting a double date.
• Skwydd: A squid-like E.V.O. with pale green skin and tentacles. He can emit smoke-like ink from his mouth for cover. When his nanites are supercharged his ink can consolidate and grab things. Rex recognizes an admiration between him and Circe after chasing Breach to Hong Kong and says he's alright with it. Skwydd says they are only friends but once Rex leaves, He and Tuck chase down Cricket and Circe attempting to ask them on a double date.
• Cricket: A cricket-like E.V.O. who has had a crush on Rex for a long time. She is good "girlfriends" with Circe, and Rex assumed that she and Tuck were becoming a couple, which she declares they are strictly platonic.
• Beverly Holiday: The younger sister of Dr. Holiday who became a mindless E.V.O. at thirteen. Although incurable, she was finally cured in "A Family Holiday" and reunited with her elder sister. She likes the band Trendbenders.
• Black Knight: The main villain of Season Three. She has blue-black hair in a bob cut and is the new leader of New Providence, replacing White Knight six months in the future. She is very power-hungry and crafty in order to achieve her sinister goals for absolute power. She is linked to Rex's past as well, presumably being part of the cause for the Nanite Explosion. Under her rule, remote controlling collars are placed on EVOs that are captured, and unruly operatives such as Bobo Haha, which at the flip of a switch can force them to be docile, or attack, and the EVOs are completely aware of their actions while they can do nothing about it. Seized game control units for the collars from Quarry's Arcade, and formed a massive Black Knight robot with four others to fight Rex in the pursuit of becoming a god.
