Azmuth is a member of an alien race called the Galvan. He is the self-proclaimed “smartest person in 5 galaxies”. He’s over 2000 years old.
Through his lifetime, he’s created many devices. Most important of them being the Omnitrix. He also created a moon named Galvan prime and their inhabitants, the Galvanic Mechamorphs. According to himself, his biggest regret is not being able to cure Malware, a galvanic mechamorph with imperfections.
He’s also known creator of Ascalon, a sword which was misused by Incurseans into blowing up a planet.
The Galvans created the Null Void, an alien prison. Azmuth might be the one who created it.
