A mysterious rift begins to open in the skies of Manhattan. Meanwhile, former agent of peacekeeping organization, "''Providence''", Rex Salazar is sparring against fellow agent, Agent Six, while musing about his need for a theme song, before getting the alert about the rift. Providence appears on the scene to stop the rift, but are unable to do anything before Rex arrives with Six and Bobo. Doctor Holiday, scientist and love interest of Agent Six, then gets a scan that shows something is coming through the rift, and Rex finds himself (unknowingly) fighting against Ben Tennyson, in the form of Humungousaur. During their skirmish, a strange metallic creature also appears and heads into the city, with Bobo and Six on its trail. Continuting their fight across New York, Ben switches to Diamondhead, Lodestar and finally Rath as Rex continues to try curing him; an annoyed Ben demands Rex stop as he doesn't even know what an EVO is. Changing back to human form, Ben is shocked that no one has heard of him despite being a celebrity. Then, Six appears with the creature, which self-destructs and renders him comatose, leaving Rex mortified and angered at Ben.
