In the video game, Bayou Billy was originally Billy West, a man who had been attacked by Louisiana gangsters and left for dead in the bayou. Through the help of a Haitian swamp dweller, Bayou Billy learned to survive in the swamps as well as nonviolent ways for dealing with alligators. Bayou Billy eventually returned to civilization and married a woman named Annabelle. However, the gangsters also learned of his survival, and sought to draw him out by kidnapping Annabelle. Bayou Billy fights through the bayou, then on to Bourbon Street, finally confronting Gordon, the gang leader, in his mansion.
