Quick and Easy Questions (please read the OP)

I'm talking about your character having knowledge of other canons prior to coming to the Omni. I thought it wasn't allowed, but I am seeing cross-canon backstories, people having info on other canons prior to coming to Omni. Like if Sasuke knew about the Dragonballs or the X-men prior to coming to the Omni. Is this allowed or nah?

I think this is a no.  Or at least, it should be a no.  Is there any reason you can't just say he learned about them in his early days in the Omniverse?

Sasuke is bringing this up not because he wants to do it himself, but because Tyson has done this with the Uchiha clan from Naruto.
That said, Tyson hasn't actually mentioned any specific named characters from the anime/manga, so far as I am aware... so I personally don't see the problem.

Also, as they are written now (letter of the law, rather than spirit of the law, so to speak), this is not against the Rules.
