Now Batman and Superman can beat up a former Batman sidekick and a partial robot.
Two more characters from the DC Universe, Nightwing and Cyborg, have been added to Injustice: Gods Among Us' roster.
The Wii U game, developed by Mortal Kombat studio Netherrealm, stars a cast of DC characters. In addition to the two newly revealed characters, Batman, Superman, The Flash, Wonder Woman, Harley Quinn, and Solomon Grundy are confirmed. Lex Luthor has appeared in his robot suit in art, but his playable status hasn't been officially revealed.
Nightwing is the guise that the original Robin, Dick Grayson, dons after he grows out of his sidekick role. Cyborg, a half-man/half-robot, is best known for being a Teen Titan. In the recent DC relaunch, he is a founding member of the Justice League.
Injustice is set for a 2013 release on Wii U and other HD platforms.
