If they decide to put Alice and the Mad Hatter in the game, I really hope they use their Tim Burton 2010 incarnations.
I have nothing against the original animated versions of those characters, but I just feel like that the temperature in carnations would be better Fighters then the animated versions.
If the animated versions of Alice and the Hatter do getting over there Tim Burton counterparts, then I at least hope that they get some aspects from the ladder, such as Alice using the vorpal sword.
