Happy Chaos is an athletic young man with light cerulean skin with white palms and soles, unkempt dirty blond hair, and a pair of short horns. A black halo with five spikes hovers above his head, similar to Jack-O' Valentine's. Rows of orange cross markings appear along the length of his arms and around his chest, collar, and back. A large black heart emblem with a golden cross and teeth appears on the center of his chest, with streaks of black ink seeming to drip down his abdomen.
He wears a pair of distinctive glasses with orange-tinted, x-shaped lenses, black leather pants, and a single black fingerless glove on his right hand. He dual wields a pair of futuristic revolvers, which are kept holstered on each hip.
