Glee/Iron Man or Avengers crossover

Hey, so I have come across some fics in the past about Blaine being Tony Stark's son, but it didn't really interest me then. Well, now it seems pretty intriguing, so does anyone know any fanfiction with that sort of story line? I prefer Klaine, so that would be lovely if that were involved :)

So if anyone could rec me some fics, I will love you forever!

Thanks!
