Well depends on What you mean by mutant if you like x-man mutant and the most powerful form of mutant is either Mutated Godhood or a Transcendent Homo Superior Physiology and John can kill anything on any magnitude. But do to the fact John is a Homo superior for good reason.

Mutants are sub-category of humanity and John is pure Human being that continually evolves infinitely beyond any mere mutant could possibly go.
