With all five aliens in his possession, Aggregor tries to return home to absorb their powers. A Plumber ambush damages his ship, so he instead heads for Los Soledad, in order to use Prof. Paradox’s time machine as an alternate power source. Despite Ben, Kevin, Gwen, and Grandpa Max’s best efforts, Aggregor succeeds in absorbing the aliens’ forms and powers, turning himself into an unstoppable amalgam of the five.
