In the first anime, Muku-Jara appears as a large being, covered entirely with long dark hair. His face is obscured by his hair and he does not appear to have any fingers or toes on his hands or feet. He wore a baseball cap and baseball mitt over his left hand for the match.
Within the third anime, Mammoth-Otoko resembles largely the same, here however his fur is dark teal. His face is still obscure and does not seem to have visible digits on his hands or feet. His baseball cap is dark blue with a blue bill and a red symbol.
