Doomsday looks like a combination of The Hulk and Wolverine, so count me in for playable!
Everyone who's not a cameo will be playable since weak people like Harley and Joker can fight Superman that's the concept of the game,
not to mention Doomsay is on the stick with all playable characters but they're gonna have to let him use the wolverine spikes
to make him different from Bane and Grundy.
