Originally one of five members in a juvenile delinquent gang, Jack grew up seeking bigger and better crimes along with his life-long friends. Their leader, now Professor Amos "Ace" Fortune, devised the means whereby the four men and one women became the Royal Flush Gang. Jack became the Jack of Clubs, complete with These costumed criminals ran afoul of the Justice League on at least two occasions. After a lengthy absence from the scene the four members minus Fortune were enlisted in a new Gang by a new Ace with our villain now known as the Jack of Spades, which encountered the Joker. This caper did not go well, however it led to a new career with this felon now known as Hi-Jack. He immediately drew the attention of Green Lantern, who nearly defeated he and Gorilla Grodd while on a Secret Society of Supervillains heist, that is until Captain Comet errantly intervened. Shortly thereafter, Hi-Jack angered teammate the Wizard, who banished him to another dimensional plane.
Another card-themed criminal was Stephen Sharpe, who realized that to get ahead he had to be creative, thus becoming the Gambler. Sharpe used his five-barreled derringer to shoot gas and smokescreens, his specialized throwing knifes and his mastery of disguise to effect his schemes.This drew him into conflict with the other caped crusader of Earth-Two's Gotham City, Green Lantern. After several encounters with his arch-foe, the Gambler ended up joining forces with the Injustice Society on two occasions. On the second adventure he, as had his counterpart Hi-Jack, employed the use of specialized cards as weaponry versus his opponents. After that incident, the Gambler retired from his felonious ways and apparently sought the love of his granddaughter Rebecca Sharpe, who would assume her own illegal identity in order to avenge her sire's death of a broken heart.
