Complete story — includes the ending

A group of Plumbers ambush Aggregor in an attempt to rescue the Andromeda aliens, but are overwhelmingly defeated. The team then learns from Colonel Rozum that Aggregor has taken the aliens to Los Soledad; Professor Paradox then appears and reveals that Aggregor is using Paradox's technology to facilitate the total absorption of the aliens. Ben and his team confront Aggregor, with Kevin attempting to reason with him, insisting that energy absorption causes Osmosians to lose their sanity. Aggregor asserts that these are merely lies, and absorbs the aliens into himself; the aliens disappear, and Aggregor emerges as a monstrous amalgamation of their forms. Note: This episode, along with "Map of Infinity," premiered as part of the special 10/10/10 event on Cartoon Network.
