Rex Salazar is a young EVO with the ability to cure other EVOs, including the ability to control his nanites using the Omega-1 Nanite. He can grow weapons and machines from his body, often using his limbs, and can communicate with technology, machines and even with nanites themselves.
Rex is Hispanic, being half-Mexican and half-Argentinian. He is most normally seen with lightly spiked, slicked back dark hair. He is also taller than most people his age.

Ben 10-Generator Rex: Heroes United
In the crossover special, Ben enters Rex's world by accident, and Rex confuses Ben for a dangerous EVO. After Rex and Ben have a fight, they eventually team up to face the worst threat either of them have ever faced: the sapient nanite Alpha. A creature that has to suck the nanites from EVOs in order to survive, Alpha had previously been banished to what was believed to be a dimension of nothingness - however, Ben revealed that the villain had ended up in the Null Void, where he managed to feed on various alien prisoners until he could escape.
Rex and Ben eventually confronted Alpha inside the Bug Jar, where it absorbs Rex's Omega-1 Nanite in an effort to create a body to sustain itself. In response, Ben used Upgrade to increase Rex's power - together, they were able to do enough damage to Alpha that Rex was able to trap him in a super-concentrated ball of Nanites, which Ben dumped into the Null Void on his way back to his universe.

Powers and Abilities
Like all living things on his Earth dimension, Rex has billions of nanites inside his body. After activation, the nanites mutate a normal being into an EVO. However, unlike most EVOs, Rex has the ability to control his nanites at will, allowing him to build various machines on his body. He can also use his nanites to communicate with a variety of machines and other Nanites and cure some EVOs of their mutations. Additionally, Rex can use his nanites to change out of his AMP suit.

Despite his long track record of defeated EVOs, Rex has had poor fighting skills. Fortunately, he has gotten better over time.
Rex's machines are powered by gravity and produce selenium as a side-effect. Additionally, he naturally gives off small amounts of selenium; Caesar compared this process to be akin to dandruff.
Sometimes, Rex does not know how to speak Spanish properly, often humorously mispronouncing words. To rectify this, Holiday volunteered to help him polish his skills.
Rex is lousy at both soccer and basketball.
