Reports are true. Ben has been moonlighting as a lone aggressor against the Forever Knights and DNAlien holdings - or so it would seem. Upon further investigation, Gwen and Kevin discover Albedo, a Galvan who, in making his own Omnitrix, became stuck in Ben's human form. Wanting Ben's Omnitrix to escape human form leads to a Ben-on-Ben multi-alien fight for control, which summons the presence of Azmuth to try putting things right.
