Regarding the other three DLC characters, awhile back Boon had a poll on his Twitter asking what certain character they wanted in Injustice. It had Batgirl, Supergirl, and Power Girl. Power Girl got the most votes and Batgirl got the least. Why bother doing that poll if you're gonna do the exact opposite of the results? Unless Batgirl was already worked on and they made that poll hoping it would be in favor, but didn't go as they hoped, I'm gonna have to question the mentality of the people making these decisions. And this is coming from someone that isn't so eager to have Power Girl in the game.
Zod doesn't really need to be his own character here. He can easily be a skin. We already have an evil Superman in the game. Whom even has a "kneel before me" line.
Scorpion is the one that annoys me the most. I like MK and I understand Scorpion is Boon's favorite character so he may be a bit biased here, but we finally have a good DC fighting game. How many of those do we have so far? I think every available slot should go to DC characters and not guest characters whom already have their own fighting game franchises and have already been in 9+ fighting games.
Plus Boon once stated that this wasn't MK and that it wouldn't have MK characters. If Scorpion is indeed in, that means he straight up lied to the fanbase.
