Fandom crossovers

I love crossovers especially PJ and HP ones, but most of them are (*british accent*) cheesy peasy, so I'm trying to write something different. They will be of different characters and there will be lots of AUs because I think they are the best (*creepy voice in the background* SO SCREW THE RESSSST!)....
I swear I'm normal.
Also if you recognise something..... it's not mine.
