For the last five years, time-traveling versions of the original team of X-Men have been bouncing around the modern Marvel Universe. And while these teenage heroes have been a huge part of the X-Men's recent adventures, they've finally returned to their place in history.
In the wake of 2012's Avengers vs. X-Men storyline, the adult Beast brought teenage versions of Cyclops, Jean Grey, Iceman, Angel and himself to the present day to, well, illustrate a point. It wan not his smartest moment, as after seeing the current state of mutant affairs, the young X-Men decided to stick around, kicking off an extended stay in the modern age. Over the course of series like All-New X-Men and X-Men Blue, these teenage X-Men went through numerous changes that one would assume would dramatically alter their personal histories.
While the teenage X-Men already made a few failed attempts to return to the past, their presence in the present became increasingly problematic as time went on. At the beginning of Extermination, the mutant-hunting Ahab, a cyborg from a dark alternate future, traveled to the modern Marvel Universe to ensure his timeline's creation by killing Iceman or another one of the original X-teens.
In Extermination #5, the teenage X-Men finally travel back to their home timeline after an intense showdown with Ahab -- but what does that mean for their present day incarnations?
