Aggregor

&nbsp Aggregor is the new villain in the Ben 10 series starting with Ben 10: Ultimate Alien. He first appeared in the Ben 10: Ultimate Alien first episode, Fame. He first appeared after Ben defeated one of his captors, Bivalvin, and then captured him. He had five alien captors: Bivalvin, Galapagus, P'andor, Andreas, and Ra'ad, and intended to absorb all of their powers. In the 10th episode of Ultimate Alien, he took his captors to Los Soledad to finally absorb their powers and succeeded (after ignoring the warning from Ben's former nemesis and current best friend, Kevin).

BACKROUND

Aggregor's race is the same as Ben's current friend, Kevin (they're both a race called Osmosian. But Aggregor is full osmosian and Kevin is half). His powers are mostly the same as Kevin's, matter absorbtion and energy manipulation. He used his powers to activate a time transporter to absorb his captor's powers and succeeded. He's more of a intergalactic threat than Ben's ultimate nemesis, Vilgax. Like Vilgax though, Aggregor also uses droid minions.
