The Injustice Gang (also known as the Injustice Gang of the World) is a group of fictional supervillain in the DC Comics universe. They are antagonists of the Justice League.

The original Injustice Gang's membership consisted of:

By the end of the first appearance, it is revealed that their entire operation was massive feint by their organizer, Libra, to test a power-stealing device. A series of "Plan B" devices the villains had been given in case the JLA defeats them absorbs half of the heroes' powers and transfers them to Libra. Satisfied with the results, he then turns his device upon the universe itself, hoping to become a god. Instead, Libra is absorbed into the universe itself, effectively disintegrating him and spreading his essence across the cosmos. The JLA later modifies the android Amazo to recover their lost powers.

The villainous Construct regroups all of the members save the Shadow-Thief, as well as a mentally-controlled Wonder Woman; the Construct is destroyed and the Injustice Gang's satellite is apparently destroyed. Later, Abra Kadabra reforms the gang yet again with all prior members when the alien Ultraa causes superheroes to lose their powers while villains' abilities are increased. This time, the Gang takes over the Justice League's original headquarters in Happy Harbor, Rhode Island, but are once again routed.

Tsukuri has not been a contender in any CBUB matches.
