asked:
If Namor is hibrid (Human-Atlantean), why he is mutant (Homo Superior, Homo Sapiens mutation)?? Or are Atlanteans homo sapiens now? :-P

Namor is a mutant because of his ability to fly, a trait not present in either of his parents or forebearers.

One doesn’t need to be a human being to be a mutant; mutations happen in nature all the time.
