An OOC! Lovely :D

I'd love to stick with First Class as the basis for Charles and Raven, X2 and X3 weren't exactly my favourite and things could get complicated with the Days of Future Past timeline. It might be better to set it between the Avengers and iron Man 2? The other Avengers could be off dealing with their own respective villains while Tony and Pepper somehow become involved with either a mutant threat or an issue which combines the two teams/timelines?

Just food for thought.
