LF: Harry Potter/the Avengers
So I am looking for a fic that is a crossover between Harry Potter and the Avengers. I think it was one where Tony was Harry's real father. The big thing I remember is that Fred & George Weasley where in the US with Harry and the Avengers. While they were there a massive serpent (possible Jörmungandr) attacked and Harry of course got involved. Draco Malfoy might have been there too but I can't remember.
