Rex Salazar

Rex is the main EVO protagonist of the series. Recruited by an organization called Providence, he helps protect the Earth from biological mutations known as E.V.O.s that were created by the same nanites that gave Rex his abilities. He can cure most Evos and manipulate machinery. He doesn't remember anything about his past.

Personality
Rex is overconfident, impulsive, and rebellious. He is quite headstrong, which according to Van Kleiss, Rex has inherited from his mother, Violeta. He has a quick wit and is constantly making jokes. However, when Rex needs to defend himself, he doesn't hold back. Aggressive and reckless, Rex prefers to smash anything that gets in his way, much to the annoyance of Providence. Despite this, Rex has also shown a selfless side to his personality, as he has cured E.V.O.s even at his own risk

Rex & Noah in popular Gay belief


Rex and Noah, by some fans are thought of as a couple. Several fan pictures of both of them during sexual activity proves this. However, this is only in popular belief as both males are interested in females in the cartoon.

Trivia

 * Rex is the only person other than Van Kleiss and Circe to have active nanites and not become a monster.
 * Rex can speak Spanish but does so with an American accent. His brother sometimes makes fun of that fact.
 * Only one of his machines can be used at a time.
 * Rex's original builds were mechanical in nature and had an orange color scheme. His new ones, centered around Rylander's control nanite, are mostly blue and are energy-based (electric whip, energy shockwaves and blades, etc).
