The Catalysts: Ultimatrix and Nanites
Ben's journey began at age ten with the original Omnitrix, evolving to the Ultimatrix—a gauntlet-like device allowing him to "evolve" his aliens into more combat-focused ultimate forms. He's a seasoned hero, a Plumber, and a living legend, having faced galaxy-threatening foes like Vilgax and the Highbreed. In contrast, Rex's powers are intrinsic, a direct result of the "Nanite Event" that reshaped his world. His Omega-1 Nanite is not just a power source; it's a key to understanding the very fabric of his existence and the ultimate cure for E.V.O.s. The inherent differences and surprising similarities between these power systems make for fascinating discussion, especially when considering how they might fare against each other.
Heroes United: The Crossover Event Explained
The "Ben 10/Generator Rex: Heroes United" special, airing in 2011, brought Ben Tennyson crashing into Rex's world through a space-time rift. This rift was no accident; it was caused by the Nanite-Alpha (Alpha), a dangerous creation by Rex's elder brother, Dr. Cesar Salazar, years prior. Alpha, originally banished to the Null Void, was drawn to the immense energy of Ben's Ultimatrix, inadvertently pulling him into Rex's dimension. The initial misunderstanding between these two powerful teenagers led to an epic showdown.
First Contact: A Battle of Misconceptions
Ben, transforming into Humungousaur, and Rex, manifesting his bio-mechanical abilities, first clashed, each mistaking the other for a threat. Ben saw an E.V.O., while Rex saw an alien. Their initial fight, featuring Ben's transformations into Diamondhead and Lodestar, was a spectacle of raw power and evolving strategy, only halted by the danger to innocent bystanders. Ben's shock at being unknown in this new universe, and Rex's empathy, quickly paved the way for an alliance against the true menace.

The Alpha Threat: A Shared Adversary
Cesar Salazar's arrival shed light on Alpha's origins: a sentient nanite creation from the original Nanite Project, capable of absorbing matter and technology. Alpha's target was Rex's Omega-1 Nanite, a move that would grant it unimaginable power. In a critical moment, Alpha even hacked Ben's Ultimatrix, turning Ben's own alien forms against him, albeit as E.V.O. versions. This forced a strategic retreat and a desperate attempt by Ben to reactivate his dysfunctional device.
The climax saw the formation of "Alpha-Omega," an entity threatening to consume everything. The solution was truly innovative: Ben, as Upgrade, merged with Rex, upgrading Salazar's machines to a galactic level. Their combined efforts, culminating in Rex shooting Cannonbolt directly into Alpha's core and then imprisoning it with the Bug Jar's nanites, were a testament to their combined ingenuity. With Alpha contained and Rex's Omega-1 safe, Cesar reopened the portal, allowing Ben (who thoughtfully consumed Alpha's nanite sphere) to return home.
