Before Vilgax came to Ben's home world his self-confidence of himself is a bit over-whelming because of him beating the Highbreeds. When Ben finds out that Vilgax is back he decides to hack the Omnitrix with Kevin's new machine. After Azmuth and Gwen warned him of what might happen he still does it and in the end Spidermonkey, Goop, Chromastone, & Way Big all escape from the Omnitrix and to make things worse Kevin has been turned in a monster again.
