Akumon is a humanoid monster with red skin and a deformed face. His basic appearance stays the same throughout his appearances, however each time he is wearing different clothing. In Go! Godman, he wore a black and white striped body suit under a velvet red robe with a golden swastika on it and a rope-like belt, as well as white gloves and black boots. In Go! Greenman he wore a full set of clothing similar to armor or a tunic, leaving only his head exposed.
Akumon was the thirty-eighth (and last) monster to battle Godman.
Akumon also appeared in episode 41 of the Greenman series. He was the forty-second monster to battle Greenman.

- Because of Akumon's head being the only exposed part of his body in both of his appearances, it can be concluded that his "suit" is nothing more than a mask which is paired with different clothing.
- A similarly-named monster, Akkumoon, appears in Zyuden Sentai Kyoryuger.
