Top Three Story Lines For The Avengers

The Avengers, The biggest superhero group in Marvel Universe, are about to film in a couple of months, but what is this film going to be about? What is it's storyline? This is crazy because the writers can do so much with this group of heroes. The team made its debut in The Avengers #1 (September 1963), and was created by writer-editor Stan Lee and artist / co-plotter Jack Kirby. There are three big story lines that I believe that can help begin the saga.
One big one was the battle between the merciless Kree and the shape-changing Skrulls. Two Alien species that have been in war for a very long time and Earth got caught in the crossfire. It is the world's mightiest Avengers job to put an end to this War. The KREE/SKRULL WAR is universally acknowledged as one of the finest and most important sagas in the Marvel canon.

A second Storyline is With Loki, the step Brother of Thor, who uses his evil magic to control The Hulk, so that he can destroy Thor. The heroes then team up to help Thor, which later they become The Avengers.

The Thrid Story line that I would go with is Kang the Conqueror you travels from the future to the past during the Timeline of the Avengers and trys to conquer earth and become king. However, Kang must go through the avenger.
