Known Background: Jack Diamond grew up in a poor neighborhood Detroit. In his world, there were only three types of people: criminals, victims, and the people who refused to be victims. He resolved to be in the last group, and when he discovered his talent for dice and card games, he hand found his way out of the cesspool. He made as much money as he could off the scum who were ruining his town (he refused to play against people he perceived as victims), and then he got out of Detroit. Especially because some of is gambling opponents were, wrongly, convinced he was cheating. He then went off to see the world: Las Vegas, Monte Carlo, Atlantic City. Pretty much anywhere there was a casino, Jack would visit. The bigger the casino, the sooner he went.

But he still was careful about who he would play against. He'd only play against people who could afford to lose what they bet. And, as often as not, these individuals were criminals, or at least people with underworld ties. Then, one night, back in Detroit, he was playing against a mafia lieutenant with a big mouth. The lieutenant bragged too much about the money he was going to be making, and off of which Big Three bigwig. What the lieutenant hadn't known was that bigwig had just that day hired Jack's private detective uncle, Lance Diamond. Jack had visited Lance that very afternoon, and while not knowing the particulars, knew who Lance's client was. And Jack was canny enough to connect the dots. Later that night, or rather, early the following morning, Jack disguised himself with an eyepatch and a pair of red sweats, and went out to help his uncle, secretly. At least as secretly as Jack could manage. He found he was as lucky fighting mooks as he was when gambling for their money, and Jack saved the industrialist's daughter along the way. Stumbling through keeping a 'secret identity' when talking to the press, Jack became the Jack of Diamonds.

Jack found he enjoyed the rush from the risks of crime fighting, and he enjoyed it when he helped the victims. So he started becoming the Jack of Diamonds more and more often, and started acquiring more and more crime fighting gear. He even met the Champions of Justice when he was gambling on a Fort Benard riverboat, although he declined the offer to join. The past few years, he's been living in Las Vegas, staying at the StarChylde Casion and Hotel. He was a founding member of the Lucky Sevens, who would become the Aces. Lately though he's been traveling again.

Personality: Jack Diamond is a cad and bounder but with a curiously strong sense of ethics. He enjoys the 'good things in life': money, fine dining, etc. and his preferred method of achieving them is money won through gambling. But he is always careful about who he gambles against. He won't gamble against people who can't afford it. He enjoys female companionship, but doesn't want a relationship. He prefers casual relationships with women who want the same. He doesn't want anyone getting hurt. But he hates criminals passionately, and will gladly risk his life to stop them. That said, he also expects to someday lose that bet, and die a horrible death. He likes helping people, but hates feeling like he's responsible for helping people.

Powers/Tactics: Jack has no powers and no particular skills to aid him with his crime fighting. He's a bit more athletic than average, though. He does have a number of weapons: he carries exploding dice; his eyepatch also contains a powerful laser, though, it burns out quick; his boots contain jump jets; and an female engineer from Los Angeles made him a card-themed flying platform. His greatest asset is his phenomenal luck which lets him survive battles that should leave him dead, and lets him land punches harder and more accurately then makes any kind of sense. As such, Jack tends to prefer to not be a frontline fighter, particularly against parahumans. He prefers fighting from the side, helping his allies and annoying opponents. There's risking one's life crime fighting, but there's also just asking for it.

Appearance: Jack Diamond stands 5’9” tall and weighs 170 lb. He has blond hair and blue eyes. He is quite handsome. As the Jack of Diamonds he adds a stage mustache, hair extensions, and an eye-patch as part of his disguise, along with the gaudy costume.
