Enter Rex Salazar. Rex patrols the ruins, using his "Builds" (massive machines sprouting from his body) to contain EVOs. He spots Ben (as Humungousaur) and mistakes him for a massive, rampaging EVO. The two titans clash in a spectacular, debris-filled brawl that defines the first act. Both shows, created by Man of Action Entertainment,
Even over a decade later, Heroes United stands as a benchmark for animated crossovers.
The fight scenes are fluid and creative. The first Ben vs. Rex fight is a masterclass in contrasting powers. Rex uses brute, mechanical builds (Slam Cannon, Smack Hands) while Ben uses biological, alien abilities. When Rath fights Rex, it’s pure comedy and fury.
