The conflict titled “Avengers vs. X-Men” arises when these two superhero groups clash due to a disagreement regarding Hope Summers, a mutant who is prophesied as the messiah. The return of the cosmic entity known as the Phoenix Force and its apparent destination towards Earth triggers this dispute, as it seems intent on merging with Hope.
The X-Men, led by Cyclops, are stationed at their base, Utopia, and are preparing to aid Hope and allow the Phoenix to unite with her. On the other hand, Captain America heads the Avengers who aim to apprehend Hope Summers for protection from the Phoenix. This confrontation escalates into a battle between both teams, while some Avengers members are in space, attempting to halt the Phoenix from reaching Earth.
In an unfortunate turn of events, Iron Man’s actions exacerbate the situation by dividing the Phoenix Force into five separate entities that bond with Cyclops, Emma Frost, Namor, Colossus, and Magik.
