Okay, I tell this very odd tale vocally to the kids at school and they love it. The name was Code Lyoko: UNCUT, but someone already had that. All the characters are the opposite of the way they are in the show. Examples are:
Jeremie: Complete Moron
Aelita: Mean
Ulrich: Wimpy
Odd:...well, he's kinda the same actually.
Yumi: See Odd.
Once I get it up on fanfiction.net, I'll post it here. It's rated PG-13 because, well, you'll see...until then.
