Ben begins by recapturing the lost aliens of Chromastone, Spidermonkey, and Goop before taking on Vilgax. However, despite trying to use Jetray, Big Chill, and Humongusaur he is unable to defeat Vilgax. Gwen and Kevin show up with Way Big, whom Ben scans and attempts to transform into, but he becomes Chromastone instead. Vilgax, unfortunately, manages to shatter Chromastone with relative ease, presuming to al that Ben has perished. Psyphon picks up the Omnitrix and presents to his master, but then Ben reappears as Diamondhead and defeats Vilgax, saving the Earth.
