who is REALLY the ultimate mutant? Nate Grey was created by Sinister to be at the pinnacle of mutant development and the weapon that defeats Apocalypse...he would literally become a god if his powers were ever allowed to reach thier max...probably way more powerful than Cable became when he unleashed his full powers in "Cable/Deadpool". and Franklin Richards, the spawn of the Fantastic Four but in reality a spawn of the Celestials...in the "Days of Future Past" (old X-Men storyline) he was said to be the most powerful mutant that had ever lived. he has the potential to recreate worlds as he wants them. thier combined powers made 'Onlslaught' the very essence of reality and the most powerful being ever... I dont have all the info on either of them (especially on Franklin) but i'm just curious as to which one is really the "ultimate" mutant?
