He is an overweight person who is partially bald. He wears a white suit with a black tie and has brown hair.
Mayor Coleman has been shown to be a greedy man as he forces the aliens to eat in order to make gold, regardless of the consequences.
During the popcorn festival he kidnapped Decka, planning on having him excrete enough gold to repay his gambling debts. Coleman later fed him meat when he refused to eat popcorn, unintentionally causing Decka to transform into his primal form and go on a rampage. When Ben stopped and returned Decka to normal, Coleman was tied up and arrested.
