After defeating the Warbot and discovering Vilgax inside, Ben's "secret voices" only worsen and begin affecting his sleep, but once Gwen discovers a sleepwalking Ben using missing items from the campsite to create his own massive Junkbot, it is up to Ben to stop his own creation.
After the Junkbot shoots the Omnitrix and it begins glowing neon-blue, an imprisoned Vilgax explains it is now a gateway through which the Fulmini Empire will invade Earth, but the only way to stop them is from within the Omnitrix, so Ben must team up with the ultimate baddie if he is to save his planet.
