Ben 10 / Generator Rex: Heroes United (Crossover Special)

“Heroes United” is a high-stakes, action-packed crossover that brought together two of Cartoon Network’s greatest heroes: Ben Tennyson and Rex Salazar. Airing on November 25, 2011, it’s the first and only crossover between the Ben 10: Ultimate Alien and Generator Rex franchises, delivering an epic multiverse battle that thrilled fans of both series.

“Two heroes. One universe. Zero time to lose.”

Episode Summary

The crossover begins in Rex’s world, where a mysterious rift opens and an unknown alien entity — the powerful Alpha Nanite — invades. As Rex battles it, another rift opens... and out steps Ben Tennyson, in full Ultimate Alien form. At first mistaking Ben for a threat, Rex and Ben clash in an incredible fight, showcasing Heatblast, Humungousaur, Diamondhead, and more.

Eventually, the two realize they’re on the same side. They team up to stop the Alpha Nanite, who’s absorbing nanites and evolving into a nearly unstoppable monster. Ben’s transformations and Rex’s nanite-based technology combine in a high-octane battle that pushes both to their limits.

The episode ends with Alpha’s defeat and Ben returning to his universe, not before exchanging a fist bump with Rex — a rare moment of respect between two very different heroes.
