Ive been thinking about DLC stages.
As we all know, this game has a bunch of stages that cleverly fuse Marvel and Capcom locales with similar themes together: theres Knowmoon (the fusion of two space stations), Dark Kingdom (the fusion of two demonic realms), A.I.M.BRELLA (the fusion of two nefarious corporations), and so on.
The two biggest Capcom series without stage representation are Street Fighter and Devil May Cry, and the two biggest Marvel properties without stage representation are X-Men and Fantastic Four. Coincidentally, these respective worlds go together really well.
Once the X-Men and (hopefully) Doctor Doom make their way into the game, Id love to see the following stages:
Asteroid S
A combination of Asteroid M and Shadaloo Base. With two universes thrown together, Magneto finds himself interested in Psycho Power and the role it could play in the advancement of mutanktkind, so he partners with M. Bison to form the Brotherhood of Shadaloo.
Temenia
A stormy East European town square with the Temen-ni-gru rising from the center of Castle Doom, combining the Gothic architecture and aesthetic of Devil May Cry with that of Latveria.
