In this thread instead of coming up with a terrible crossover idea come up with a terrible fanfic idea in general. Bonus points for using as many horrible fanfic cliches as possible. Some examples:
Naruto Peggy Sues himself back in time but discovers he has traveled into an alternate timeline where he is stuck in Fem!Naruto and is stuck in a Time Loop centered around the Chunin Exams. Includes at least one vicious rape of Sasuke scene per chapter.
Edward Elric seals his brother's soul not in a suit of armor, but in the body of Roy Mustang! Homoerotic overtones abound between the two (three?). Includes absolutely no action scenes.
How was it that Aang survived one hundred years without aging? He's a VAMPIRE!
