Its not ridiculous to want her, I want Orion and Cyborg Superman but I think disappointment is unjustified. Cain has never made it any mainstream Batman media to my knowledge, she's even spent half her comic life in limbo. On top of she hasn't been Batgirl in almost a decade and that role is still associated with Babs. Cains chances were outright non existent to begin with.
that's true. but Cass was added to the Injustice mobile game. And she was in the DC Online game, too. So she has been in some games.
Plus, the Injustice universe is an alternate world, so there can be more leeway in including less mainstream characters.
also, just in terms of a fighting game, Cass would be a natural fit. Just look what they did with the new Robin - that's essentially how Cass would play.
And Cass would be a natural fit for the dystopian, messed up world of the Injustice universe.
And Cass doesn't even have to be Batgirl, since she hasn't been that in the comics for a longtime. She could be called Black Bat or her current codename Orphan.
Cassandra Cain has a possibility of being included as an alternate skin if Barbara makes it in there. Cain would never be the main fighter added but I can see her as an alt, similiarly to Powergirl or Jon Stewart
that's possible. but Cass' fighting style would have to be different from Babs' fighting style. I don't know if the skins will actually change moves, but I guess it's possible.
however, I thought I read somewhere that in the stream yesterday, they mentioned that no Injustice 1 DLC characters would make it to the main roster. So, I guess that rules out Babs Batgirl.
