Yeah, it's kinda weird cause Mr. Immortal is classed as Homo supreme, the final step of evolution, apart from both humans and mutants. I remember this comic where a clone Sinister had learned that there are 3 stages, in the 1 (humans) will become 2 (human and mutant) and then 1 again. A final step, and I wonder if Mr. Immortal is the first of that final step of the 2?
