Warning: SPOILERS for A.X.E: Death To The Mutants #3
Marvel's Eternals are officially no longer Eternal, and death now means the same for them as everyone else. The species are ancient; having spent eons on Earth, they've witnessed the beginning of human history all the way to the present day. The future looks dim as the all-powerful Progenitor Celestial finally hands down judgment to the Eternals in A.X.E: Death to the Mutants #3, and the lives of Ikaris, Sersi and the others will never be the same.
In Marvel's new world-ending Judgment Day event, the Eternals have attacked the X-Men's paradise island of Krakoa, a sovereign nation that provides a safe haven for all mutants on Earth. According to the Eternal Druig, the X-Men represent "excess deviation", and since one of their guiding principles is to correct said excess deviation, that leaves the Eternals little choice in their actions. But what began as a simple war between the Eternals and the X-Men has quickly become a war for survival as the Progenitor Celestial awakens; it gives the people of Earth 24 hours to justify their existence - and if they fail the Progenitor's tests, it will destroy the Earth and everyone on it will perish.
In A.X.E: Death to the Mutants #3, written by Keiron Gillen with art by Guiu Vilanova, the Progenitor Celestial has heeded Ikaris' fateful words. "Death to the Eternals!" he said in the previous issue; Ikaris is wracked with grief over the secret of his species' resurrection. Whenever an Eternal dies, a human's life force must be extinguished in order to resurrect the Eternal. The Progenitor smashes the resurrection devices used by all Eternals. "Ikaris will not be back," assures the Machine that is Earth (the narrator of the Eternals series). "No Eternal will be back."
The Eternals Have Lost The War With The X-Men - Forever
With this stunning moment, the status quo of the Eternals changes forever. The species took unbelievable risks in battle, safe in the assumption they would quickly resurrect after every fight - and they were right to do so. Those days are over for them...but not for the X-Men, as they can still return from the dead thanks to their own resurrection techniques. Since the Eternals can die but the X-Men cannot, this means the war is effectively over; even if the Eternals defeat the X-Men in battle again and again, they will simply return to fight another day. The Eternals cannot.
Unless another method of resurrection can be found, all Eternals that died during the course of Judgment Day are dead permanently. This is an astounding development, especially for the death-averse Marvel Universe. The Eternals are finally judged as a group, as the Progenitor promised, and they are not worthy of eternal life.
