|Voiced by||Jeff Bennett|
Azmuth is a Galvan (the same species as Grey Matter, one of Ben Tennyson's original aliens) from Ben 10 and later Ben 10: Alien Force and Ben 10: Ultimate Alien. He originally created the Omnitrix to help the peoples of the galaxy to understand each other better, but was disgusted when people like Vilgax considered it a weapon rather than an instrument of peace. He later created the Ultimatrix, which was stolen by his former student Albedo shortly thereafter and turned into a weapon to be used against Ben Tennyson.
