Isn't there one with Bizarro?

If there is I haven't seen it. Are you sure your not thinking of the iOS version? I'm not talking about those support cards, I've seen Bizarro and a bunch of other characters on there. The supergirl card I saw is in the console version of the game. It opens as part of a bunch of hero cards that feature a number of comic book covers. supergirl aside, the only characters I've seen featured in them are current roster characters. She is the only non-roster character I've seen, which just seems odd.

Are you talking about the hero card Portrait packs? Because I'm pretty sure that Bizarro was in one of those lol I could be wrong but once I get home, I'll go check

Not only Bizarro or Supergirl...

Alfred Pennyworth confirmed for DLC!

Those are not what I'm talking about. You have a player card in the console version (similar to COD's player card) that can be customized. There is a huge hero pic/portraits card as part of it. Aside from character specific portraits there are portraits featuring notable comic covers and drawings of said characters from the roster. Supergirl is featured in one of them.

here is what I'm talking about:





I actually just noticed Bizarro while taking those pics above. I honestly mistook it for a Superman reference. Still even at that, Spergirl is the only character I see in any of those portraits that isn't in the current roster.
