These characters are characters from the Marvel Universe. They can be characters taken from prior to our cut off point, after our cut off point, from X-Books or not. They can be original characters created by the player. The main distinction is that the character originates within the Marvel Universe. There is a partial list of encouraged characters from the X-Men books that we would like to see cast.

We accept applications for Marvel Universe characters in general; they do not have to have appeared in an X-Book. It can be a meta-human character or an alien, or from a 'known' other dimension. This covers characters borne of this Universe even if they never appeared in a comic. If you do choose to apply for a character that is featured in the Marvel Universe, please consider what kind of support characters would be needed to make this character a viable option. Solo features are more likely to be accepted than ones in groups. For example: Why would the Human Torch be around without the rest of the Fantastic Four?
