Jack was a member of Ace's Royal Flush Gang.


Jack was granted powers by Ace, who had hoped she could form a new family. However, they abandoned her in favor of a life of crime. During a final showdown with the Justice League, Jack took on Hawkgirl in aerial combat, but found his mastery of combat insufficient to beat the Thanagarian warrior.

After Ace died, Jack lost all his powers.

Background information

Jack – referred to as Kabuki Jack in the script – is a subtle nod to the character Samurai Jack. After losing his powers, Jack closely resembles Samurai Jack voice actor and DCAU regular Phil LaMarr.
