No one has asked, don't worry, but I'm a non-canonical kinda guy. Sorry, OCs only, in any RP I'm in. 

In a normal RP, having ANY sort of canonical character that is tied to the main cast has 100% chance of causing some sort of railroading in the gameplay. In this case, however, it's for the second reason I don't allow them: you can't properly stat-out a character in canon, and you definitely can't do so in a separate universe. :P

Sorry. :x
