It begins with a lie. For five years, Ben Tennyson has told himself he’s done. The Omnitrix is a trophy on a shelf, a relic of a summer that feels like it happened to another boy—a loud, cocky, freckled kid who shouted catchphrases and turned into a Pyronite to stop a robber stealing a hot dog cart.

Ben looks at the rebuilt Omnitrix—now a sleek, black, adult watch—and says, "We keep going." It begins with a lie
