The latest character to be confirmed for Injustice 2 was Swamp Thing. Other confirmed playable characters for Injustice 2 so far include Batman, Blue Beetle, The Flash, Harley Quinn, Superman, Supergirl, Wonder Woman, Deadshot, Gorilla Grodd, Aquaman, Robin, Cheetah, Poison Ivy, Catwoman, Black Canary, and Atrocitus.
NetherRealm's Ed Boon has said the game will feature obscure characters.
Earlier this week, NetherRealm showed off female fighters Cheetah, Poison Ivy, Catwoman, and Black Canary in a new gameplay trailer. Another video focused exclusively on Black Canary and her devastating moves.
Injustice 2 launches for PS4 and Xbox One on May 16. You may not have to wait that long to play, however, as a closed beta is going on right now. This beta just recently added Black Canary to its playable roster.
In other news, an Injustice 2 mobile game has been announced.
