Sonnyboy is the millionaire son of the famous scientist, Jonathan Serge, although he doesn't share his father's good nature.  He is the owner of multiple properties, including the Sunset Casino.  He's at odds with Blackjack most of the time, always trying to gain to the upper hand.  Crook, villian, and all around bad guy, Sonnyboy is not one to mess with.
