Ben, Gwen, and Kevin are accused of impersonating plumbers. Eventually, Kevin gets his badge taken away and will do anything to get it back. Meanwhile, a masked figure is zapping power out of other lifeforms, who is eventually revealed to be Mike Morningstar (All That Glitters-Season 1), who is horribly disfigured. Ben eventually defeats him by changing into various aliens repeatedly. Mike Morningstar/Darkstar is arrested and sent to the Null Void, while Kevin gets his Plumber's Badge back and Gwen also gets a Plumber's Badge. Then he goes to show his mother Mrs. Levin his Plumber's Badge.
