Mammon is a complex character, the second oldest of seven demon brothers. He is driven by a hunger for wealth and power, but beneath his arrogance lies vulnerability and loyalty. His appearance is striking: messy white hair, tan skin, and captivating blue and yellow eyes. He often wears an open brown and white aviator jacket, a black shirt, blue jeans, and black boots. In his demon form, he has horns and bat-like wings, and wears a studded jacket and pants.
