The special begins with Rex (from Generator Rex) chasing a standard EVO in Hong Kong. A sudden, massive energy surge—caused by a breach in the space-time continuum—sucks Rex into a glowing green portal. He lands in the middle of a battle between Ben Tennyson (the wielder of the Omnitrix) and a swarm of robotic drones sent by the evil nanotechnology collective known as the Consortium.
The immediate chaos is palpable. Ben, assuming Rex is an alien threat, attacks. Their first fight is a highlight of the special, showcasing signature moves: Rex’s Builds vs. Ben’s aliens, including Humungousaur, Echo Echo, and Big Chill. The dialogue is snappy, and without English subtitles, viewers might miss the rapid-fire banter where Ben accuses Rex of having "a lot of junk in his trunk" (referring to his techno-organic machinery).
Eventually, they realize they are on the same side. The villain of the piece is a mutated Alpha Nanite—a sentient piece of the meta-nanites that controls all technology. Alpha nanite successfully absorbs part of the Omnitrix’s DNA repair function, creating hybrid monsters that are part EVO, part alien machine. The duo must learn to combine their powers—Ben turning into Upgrade to merge with Rex’s machinery, creating a devastating combo attack.
