So that Injustice: Gods Among Us Batgirl rumor turned out to be true, to no one's surprise. On the first Friday of May, an Xbox LIVE leak saw an entry for Injustice showing Batgirl as the next DLC character (the first was Lobo), and as we speculated, Barbara Gordon is indeed the lady we'll be seeing.
If you're wondering about the whole paralysis thing as Oracle, bear in mind Injustice does bring in several New 52 influences, like Captain Marvel being renamed "Shazam." In the New 52 DC reboot, Barbara retakes the mantle as Batgirl, which will also be the case here for Injustice: Gods Among Us.
A new trailer released today shows Batgirl facing off against the Joker, dressed as he was the day he shot and paralyzed her. That's pretty fitting. Currently, we have no release date, but the DLC will be priced at 400 MP or $4.99 USD.
