Mammon is the Avatar of Greed and is the second oldest.
He wears a loose black jacket with yellow stripes. Underneath it, he wears a white wife-beater with black edges. He also wears simple, skinny jeans with yellow stripes.
Mammon is greedy. He is immature and is the biggest troublemaker of the brothers. He's egotistic and prideful, though it seems only a façade to hide his soft nature.
He's a bad liar. He tends to shout whenever he is angry or upset and growl when irked. He acts impulsively.
