Azmuth, a Galvan, resembles a frog. He has green eyes, rectangular pupils, and tendrils. In flashbacks, his tendrils were shorter. Originally, he wore a dark green jumpsuit. He was paranoid, impolite, and pessimistic. He refused to repair the Omnitrix and considered the universe unworthy of saving. In Alien Force, he became less pessimistic and more serious, concerned about the universe's safety and Galvan Prime. 
he also made the Omnitrix to end wars and to bring peace.
