The user claims to have found it in the game’s source code. Lobo was recently identified by Ed Boon himself as the first upcoming downloadable character for the game. And with the Man of Steel movie coming, it wouldn’t surprise me to see Zod featured in the game (I wonder who will be kneeling to whom between Regime Superman and Zod). Scorpion tends to show up in other games, so not a surprise there. But Batgirl? Why her over, say, Martian Manhunter, Power Girl, Black Canary, or anyone else?
Here’s hoping its Cassandra Cain or Stephanie Brown.
