Fan Casting Marvel Studios' Avengers: Doomsday Casts and Recasts

Doctor Doom was friends with Tony Stark in school. After taking over the TVA he sees a clip of Tony's death and he sees that the Avengers were there. Thinking the Avengers killed Tony, Doom tries to avenge (no pun intended) his old friend by destroying the 616 Earth with an incursion with 10005 Fox X-Men Earth and taking power of Franklin Richards, Monica Rambeau, Loki, Shang-Chi, Kamala Khan, and Sentry.The X-Men find out what is going on and team up with the remaining and newly recruited (in this movie or past movies) Avengers to defeat Doom and Doom's evil Avenger variants.
