Billy the Kid, also known as William Henry McCarty, Henry Antrim, and William H. Bonney was a 19th-century outlaw, and according to legend he killed 21 people, but it is believed that it was actually four to nine.
In the Sorceress Billy and Machiavelli meet up to kill Perenelle on Alcatraz, but ultimately fail when Perenelle steals their boat, get back to San Fransisco, and steal Billy's Thunderbird, stranding Machiavelli and Billy. Black Hawk eventually comes to rescue them.
Billy and Machiavelli decide not to release the monsters on San Francisco, and therefore both become Warlocks or wato loga. They are knocked unconscious by Virginia Dare and her Flute.
Billy and Machiavelli have become allies with everyone who remains on Alcatraz. They fight the monsters and discover magic spears that are dangerous weapons. He almost kills Perenelle accidentally, but the crow goddess leaps in front of her. Billy is injured by a Karkinos, an enormous crab monster, but Machiavelli sacrifices some of his own strength - aging himself considerably in the process - in an attempt to save Billy's life.
Powers and Abilities
Billy is described as short and slight, with a thin and scrawny body. He is unkempt looking, unshaven, with a stubbly beard and straggly, long hair. He has bright blue eyes that occasionally flash crimson. He is thin faced, with prominent front teeth. He generally wears a t-shirt (although has been seen in a denim shirt also) with frayed jeans and cowboy boots, which he has hand made.

Black Hawk: He also has a long friendship with Black Hawk.
Virginia Dare: He apparently is also an old friend of Virginia Dare's .
Scathach: Has teamed up with Scáthach on at least one occasion, in "Billy the Kid and the Vampyres of Vegas", where he describes her as "striking."
His gang of immortals: He mentions this to Macchiavelli when they plan to kill Perenelle.
