Creator of the Omnitrix, Azmuth (voiced by Robert David Hall) is a Galvan, the same species as Grey Matter, that appears in Ben 10:Secret of the Omnitrix. Azmuth is very pessimistic, unwilling to shut down the Omnitrix's self-destruct at first, despite it meaning the destruction of the universe (including him), simply because he didn't believe the universe to be worth saving. This is because he invented the Omnitrix to so the aliens of the universe would have better understand of each other, but people like Vilgax only wanted to use it as a weapon of war. In Alien Force, Azmuth has become less pesimistic and more serious, showing a no-nonsense personality in War of the Worlds.

He's also very paranoid, evidenced by his creation of such a self-destruct system and the great pains he takes to hide his world from the rest of the universe. However, he lightens up and repairs the Omnitrix for Ben, unlocking a new alien form, Way Big in the process. He abandons Xenon after it is attacked, taking his assistant Myaxx with him. Azmuth seems to be quite old, as he has a beard and walks with a cane.

Azmuth returned in Ben 10: Alien Force in "Good Copy Bad Copy". He revealed that Albedo used to be his assistant and he came to retrieve the Omnitrix created by Albedo. Azmuth states that only one Omnitrix is allowed in the universe.

Azmuth returns yet again in Ben 10: Alien Force in War of the Worlds:Part 1 and War of the Worlds:Part 2.
