Dimensions Collide: The Legacy of Ben 10/Generator Rex: Heroes United The 2011 crossover special, Ben 10/Generator Rex: Heroes United

The plot begins when a mysterious rift opens over Manhattan, pulling Ben Tennyson from the Ben 10: Ultimate Alien timeline into the gritty, nanite-infested world of Generator Rex
. Their first encounter follows the classic "heroes fight before they unite" trope: Rex mistakes Ben’s Humungousaur form for a dangerous EVO (Exponentially Variegated Organism), leading to a high-stakes clash in Central Park. The true antagonist, however, is
, a sentient "Alpha Nanite" created by Rex’s brother, Caesar. Alpha seeks to stabilize its form by consuming the Omega Nanite residing within Rex, but it quickly discovers a more versatile target: the energy of Ben’s Ultimatrix. The villain’s ability to copy Ben’s transformations—manifesting nanite-powered versions of Heatblast and Four Arms—forced the two heroes to bridge their differences. The climax features a stunning fusion where Ben transforms into
and merges with Rex’s mechanical builds, creating a supercharged tactical suit that successfully neutralizes the Alpha threat.
