The villainous Ragnarok (the alien who killed Kevin's Plumber father) escapes galactic prison and seeks the hidden key to unlocking his ship from hyperspace. Kevin, finding his mother's house ransacked, learns of his connection to Ragnarok and thereby seeks a vendetta for his late father. Ben and Gwen accompany him to recapture Ragnarok and to keep Kevin from harm and on the straight and narrow, but Kevin, for whom this is personal, would prefer to handle Ragnarok alone. Written by
