BlackJack is a gambler who never loses, he wins so often, he gets bored. The Godfather offers him to be part of the impostor with the promise that he will get the biggest bet, BlackJack accepts the offer and started infiltrating space ships as an impostor
BlackJack has a fairly calm demeanor, but a little bit brutal. He's smart and a bit cocky. His ability is to guess the spacecrew's role, if he is right, the spacecrew dies, if BlackJack's wrong, he'll die. He is cunning in deceiving spacecrews.
