Marvel has revealed X-23's costumes for Ultimate Marvel vs Capcom 3!
The two new ones are her X-Force/current maskless outfit with blue instead of black, and an outfit based on AoA Kirika that's green.
She will also be getting a special timed exclusive outfit as part of the Femme Fatales pack if you preorder through Gamestop. That one will be her X-Men Evolution premiere outfit. This one is more than just a simple color swap(full on model outfit) and will be going up for purchase at a later date if you didn't preorder through gamestop. Glad to see they worked with Craig Kyle too on the choices, though I think they may have lowered the amount of credit he's supposed to get for what he created.
Pictures to follow at a much later date on KP. For now, click on over to Marvel's site to check out their exclusive!
