Blackjack is the most sinister and threatening of Ace's enemies.  He was the one who got Ace into crime when he was younger, and it was only after a terrible accident that left Jack both crippled and bitter, did Ace manage to escape his grip.  Blackjack doesn't hesitate to try to do away with Ace and Cosmo when the opportunity arises, and will go to great lengths to try to rid himself of these two nusances.  He is also Mona's father, which doesn't help when she and Ace want to have any kind of a relationship, especially since he is very protective of her.  Although, he has been known to back down when she's had her mind set on something.  He's the owner to the Croesus Palace casino, not to mention the most powerful criminal in ElectroCity.
