I was thinking of making an X-Men RP but I think I will join this instead. 

When I do an X-Men RP I like to do the RP in arcs which have its own set of villains and members. By that I mean I like to have canon and OC characters within my X-Men RP's. I also like to throw in subplots such as kick and even rewrite events that have already happened. Generally, it does not follow any of the comics and is a completely new line where the X-Men have to deal with it as if it never happened. That is just me though and is in no means a rule one should have to  follow.
