When he was a young teenager, both Billy and his sister were orphans in London. Life was hard for them with Billy having to steal food to feed Lilly. They were spotted by Geese Howard, who was on a business trip in Europe. Seeing himself in the two orphans, he takes them in after he sees Billy's skill with his bo.
Years later, Billy became the crime lord's right-hand man. Geese would hold The King of Fighters tournament every year with Billy as his champion. Billy was undefeated until he was beaten by Terry Bogard, who moved on to defeat Geese. Billy then swore revenge against "The Lone Wolves" Terry, Andy Bogard, and Joe Higashi.
After his boss' supposed death, Billy went back to England with his sister. In order to adequately provide for her, Billy continued his life of crime and joined Wolfgang Krauser. Although it seemed like he was loyal to the nobleman, Billy was actually working undercover to search and destroy Geese's impostor. His additional order was to overthrow Krauser. He succeeded in the former and continued to serve the real Geese until the latter's death.
