Ash Bison (Criminal Case)

Initially appearing as the 35-year-old subordinate-turned-leader of The Vipers street gang, Ash had neck-length black hair and donned a blue cap and a black jacket over a white T-shirt with a bullseye drawn on it. He also sported a tattoo of The Vipers logo on his neck.

In his first appearance, it is known that Ash was right-handed.

In his second appearance, he had an oil stain on his jacket and it is discovered that Ash was asthmatic and chewed gum.

At the time of his death, now 40 years of age and owner of the arcade game Double Vipers, he was seen with shorter hair and was wearing a green beanie, a white-and-teal T-shirt, and a pair of black pants.
