Batgirl will indeed be a downloadable character for Injustice: Gods Among Us.
Developer NetherRealm has confirmed as much following rumours which emerged when the character prematurely appeared as a download on Xbox Live Marketplace.
"Looks like the bat's out of the bag," said NetherRealm via Twitter. "Batgirl is a playable DLC character in Injustice. Catch her gameplay next week."
NetherRealm also shared some Batgirl artwork, pictured above-right.
The first confirmed Injustice DLC character, Lobo, will be released on May 7.
We said in our Injustice: Gods Among Us review: "Loose mechanics mean its long-term appeal is limited, but fans of the source material with love the playful way it toys with the DC Universe."
