Jack of Clubs

Pre-Crisis
Originally a member of Amos Fortune's Royal Flush Gang as the Jack of Clubs, the man known only as Jack later changed suits to Spades and eventually joined the Society of Super-Villains as Hi-Jack, robbing a bank with Gorilla Grodd as an initiation and inducting a confused Captain Comet into the Society. Later, he fought Mantis the Power Parasite alongside the Society when they challenged Darkseid. He angered the Wizard following that mission and was banished to an other dimensional nether world but was later revealed to have returned to Earth and been jailed. The Justice League of America tricked him into divulging information about the Society to them while he was in prison.

Post-Crisis
Years later, he reunited with his original Gang (minus Ace) as the Jack of Clubs once more, and fought first the so-called 'Justice League Detroit' and subsequently the second Royal Flush Gang, now led by Amos Fortune himself. Betrayed by their former leader, the King, Queen and Ten died at the hands of the second Flush Gang, and Jack fled into the woods, the sole survivor.
