The past history of the X-Men on Earth-804 mirrors that of their Earth-616 counterparts until the Kree-Skrull War. In this reality Rick Jones was killed early on in the conflict, prolonging the war. With Kree forces threatening to invade the Earth, the X-Men's leader Professor X would mentally summon Earth's heroes to help lead the counter attack. While the X-Men were not depicted as participating in the battle, it is presumable they participated in the efforts to drive back the Kree invasion until the battle finally ended.
