5 Crossover Story lines Marvel should use in future Avengers movies.

1. Avengers Disassembled/House of M - Disassembled and House of M are what people call introduction into what Marvel comic books is today. The story line is the Scarlet Witch has gone insane after she comes to the realization that her children that she once had were magical constructs and weren't real. To make matters worse Scarlet Witch has grown to be able to manipulate reality. This warping of reality gets 3 of the Avengers killed.
   
   
   House of M the sequel crossover to Avengers Disassembled had the New Avengers and the X Men unite to make a decision. Whether or not they had to kill Scarlet Witch. At this time Wanda’s powers are disrupting reality and it could only be a matter of time before this could have terrible effects. Overhearing these decisions Quicksilver returns to his sister's side and convinces her to rewrite reality where Magneto fought and won the war making mutants the most dominant race on Earth.
   
   House of M, mostly focused on the X Men and was not well received by readers, but the series had several different realities to play with. For starters Spider Man was given world where he was loved by all and Gwen Stacy was his wife. Captain America was never frozen and was able to live through old age. Several different superheroes run countries because of their dominance such as Hulk ruling in Australia
   
   This story would likely never happen because of the ownership of the X Men by Fox, but with the recent agreement between Sony and Marvel i think anything is possible at this point.
   
2. Secret War (2004) - In this story Avengers discover that their memories have been tampered with and to make matters worse a Assassin of Latvian Origin is attacking the heroes. What they discover is that they were part of a operation by Nick Fury to prevent a war from happening between Latveria and The United States. Although for this war to have been prevented Fury had to do something terrible and essentially create a terrorist attack on Latveria using the heroes as pawns in this fight.
   
   Unlike the previous crossover, I think this one has a much better chance of seeing the light of day, however with the tone of the current movies I feel like wouldn’t see this any time soon. Because it such a dark movie, I think it could be another Captain America movie as those movies seem to be where much of the gray shaded stories happen.
   
3. Planet/World War Hulk - This story was tied into a very popular story called World War Hulk that was done the year before that. Many fans hope that we could see a World War Hulk movie, however recently Mark Ruffalo revealed that Marvel does not actually own the rights to a solo Hulk movie at the moment. In this story the Hulk takes revenge on the Illuminati (The group of superhero comprised of Reed Richards, Dr. Strange, Professor X, Namor, and Black Bolt) for send him off world where found happiness only for it to be taken away by explosion from the ship he was sent in. This has a lot of good potential, seeing Mark Ruffalo's Hulk face off against a Robert Downey Jr. Tony Stark would be a good. Definitely something far different from how the two characters get a long in the current movies.
   
   
4. Secret Invasion/Dark Reign/Siege -
   
   This is 3 big stories that tie one into another.  In this story and Alien race known as the Skrulls who have the ability to impersonate other people. The Avengers try end the war but it is Norman Osborn who comes out the hero of the story. As gratitude Osborn is placed as head of SHIELD which he renames HAMMER, and begins to dismantle everything Tony Stark has built.  Contrast to what Marvel is doing now this era of Marvel was very dark. The bad guys rule the world for around a good 6 months in the Marvel universe. With the Green Goblin in control he creates a new team called the Dark Avengers which are villains impersonating heroes. Osborn uses SHIELD and his new Dark Avengers to run rampant all over New York until the Seige cross over happens. Siege takes the Dark Reign story line and shatters it when Norman Osborn decides to make an attack on Asgard (which is now floating over Oklahoma). This starts a war between the Dark Avengers and Asgard. The Avengers lead by Bucky Barnes charge into action and stop Osborn from destroying Asgard.

5. 
   Fear Itself -
   

In this crazy story, Red Skull’s daughter Sin frees the Serpent Odin’s brother who plans to take Asgard. Fear Itself feels like it was meant to be this big action movie. A huge battle between good versus evil. The reuniting of the Avengers and this epic moment where the Avengers don Asgardian armor, how cool is that?

If you guys have any great stories that should be the next Avengers movie besure to leave it in the comments below?
