Rex Salazar is a fifteen-year old (sixteen later in the show) amnesiac human-looking E.V.O. Like all of the E.V.O.s he has suffered a unique mutation, his being the ability to grow machines out of his body for virtually any occasion and then absorb them back into himself when done (this power is not unlimited he can only grow certain machines out of specific parts of his body and the only reason he can do this, as revealed in the episode Dark Passage it is because he was given the first batch of nanites instead of the ones that other people got). He can also cure some Evo's of their mutations in addition to using his Nanites to communicate and control nearby machines. Agent Six believes that there is something wrong with him (aside from the amnesia and Nanites) and believes that the reason why he's struggling with his nanites is because of his inability to control his emotions. Rex often vents his frustrations (such as the size of his room and the "all work and no play" outlook of Agent Six) by riding around the Evo habitat on his motor bike and breaking out of the base to go on "road trips" with Bobo Haha.
It is revealed by Van Kleiss in the first episode "The Day that Everything Changed" that he and Rex were both at the Nanite explosion. It is revealed in the episode "Frostbite" that if he absorbs too many Nanites he can't control them and they can take him over and possibly make him explode. It is also revealed in the episode, "Dark Passage" that Rex had an accident when he was young and that Dr. Rylander gave him the first batch of fully developed, fully programmed nanites to save him. Although some unexpected side effects came later. It was revealed that he has an older brother named Caesar(who he meets in the episode Mixed Signals and Caesar reveals that their parents, Rafael and Violetta- were sadly killed in the nanite explosion and Caesar joins Providence), and that it was Rex's powers that saved them from the Nanite Event explosion.
His main love interest, beloved sweetheart and girlfriend is the human-looking E.V.O. Circe, who possesses unusually strong hypersonic/sound abilities. She returns his strong romantic feelings.
E.V.O. Abilities and PowersEdit
Rex has the ability to generate a total of nine different bio-menchanical machines from his body and can return to his human form when done. Previews of the show have suggested that damage to the machinery in battle does not effect his nervous system or body in any way. Rex can generate the following machines from his body:

Personality and CharacteristicsEdit
Rex is shown to have a externally overconfident personality, suggested by his bold remarks and inability to listen to Agent Six's orders during battle. In the initial preview, it is revealed by Dr. Holiday that he has insecurities about his capabilities. She states that his "machines fell apart" due to the fear of disapointing Agent Six. Rex refers to Six as "a nanny, just more Agro" (though apparently the agent himself despises the use of the term). He also admires Six's martial arts abilities and secretly looks up to him, hoping that one day he will teach Rex some of his own tricks.
He is very headstorng, stubborn and willfull, which he had inerited from his Mexican mother, Violetta. He is also quite good-hearted, tender, caring, selfless, considerate, tolerant, strong-willed, self-sacrificing, heroic, high-spirited, and desires to help people and save lives whenever he can.
