Billy has a slim but fit body, and wears a punk rocker get up. He wears hand wraps and pants that are held up with suspenders. His blond hair is styled in a mohawk and in his Shadaloo C.R.I. profile art, his eyes have facepaint applied to them.
Billy is said to be loud, ostentatious, and rambunctious, enjoying causing a ruckus and provoking the attention of others. Outside of this however, he has a deep knowledge and appreciation for romantic literature and theater, and is loyal to his friends.
Billy is a punk rocker affiliated with the Skull Cross Gang, who recently emigrated to Metro City from the United Kingdom and lives with a friend after meeting them through a major punk rock event. After one evening of carousing through town, Billy's antics caught the attention of the Skull Cross Gang, who invited him into their ranks.
Billy fights like a boxer, attacking only with his fists. His favorite combo is a series of two jabs followed by an uppercut. Although he is rather weak, he likes to strike enemies from behind and can be annoying when teamed up with other thugs.
- Like Axl and Slash, Billy's backstory and design is reminiscent of the punk rock musician and Generation X band member Billy Idol, who migrated to New York City to start his own solo career in 1981.
