UNCANNY X-MEN #369 (1999)
"Collison Course"
Today for the X-Men the term that would be best to describe their location would be "Lost in space" but for the X-Men they're half a Universe away, in time, the X-Men realize that they were called by the mysterious creature Ejulp to help stop the rampaging Juggernaut on one of his rages as he managed to get himself into the damaged dimension, little does he know the longer his rampage goes the more damaged the dimension gets, Professor X and the rest of the X-Men do their best, with Wolverine and Charles snapping Cain down, Kitty Pryde, Colossus, Night-crawler and Gambit figuring out how to get themselves out of the dimension before it's too late and Storm finding out what's behind all this, but the answer and the conclusion may shock her and the X-Men more than they expected.
