The team encounters another alien who escaped from Aggregor and, through him, learns more about Aggregor's goals.

Ra'ad, the last of Aggregor's escaped prisoners, attacks Ben and informs the team of the true fate of his comrades. He finds a safe hiding place but one that endangers Ben in the process.

Aggregor has all five aliens. The Plumbers manage to disable Aggregor's ship, forcing Aggregor to find a new way to absorb their powers. The team makes a last ditch effort to save the alien prisoners.

Aggregor has absorbed all the powers of his captured aliens. Now he's after the Map of Infinity.

With the fourth piece of the Map of Infinity almost in Aggregor's clutches, the gang chase him through the artificial planetoid known as Perplexahedron.
