Mutants are the next stage of evolution. Evolution depends on mutation - the genes of the offspring deviating from their progenitors. Some would call the X-gene "excess deviation" - namely, the Eternals. Those people are gonna need to be taken down a few pegs. As the seismic events of A. X. E. rock the Marvel Universe, Judgment Day is here, for good or ill. And the newest team of X-Men must face the truth about themselves - and what they've done! Plus- Fear the Children of the Vault! They are hyper-evolved humans from a society whose time moves much faster than our own. Each time the X-Men defeat them, they retreat to their home, evolving further to a more advanced generation. This time, they will not be stopped so easily. And elsewhere, what secret mission has Forge taken on? Collecting X-men (2021) #13-18.
