A handsome cyborg with a casual and carefree personality.
He's an avid fan of the Starlight Knight show, not only referring to himself as one of the Starlight Knights, but repeating many classic lines from the show.
Refers to his pair of special custom-made high-caliber revolvers as "the girls". They appear to have been a gift from an old friend.
He may look unreliable, but once he gets serious Billy can take on any challenge.
