Oh god, Arthur looked so mad awesome.
I mean the wacky run/jump/attack animation's, the shorts, the music, the voice! They absolutely nailed his character.

Spencer looked fun too, but I dunno.
Modok and magneto are a suprise for me though. Modok I'm just wondering what the fuck he will play like, but I wasn't expecting mags to return. I hope he's still as awesome since he is my main in mvc2.
