Gamao is a large man who resembles a hobo. He is seen to be extremely lazy and often refuses to do any work, even if his survival and duty as a Nightmare depend on it. Gamao is seen suffering from starvation and being underpaid.
In his human form, he is a medium sized fat man that is something of a lazy bum and is constantly unemployed. In his true form he resembles a humanoid toad who wears somewhat medieval clothing that would not seem out of place in a role playing game.
