last surviving MUTANT

The only mutants that would be able to survive are Onslaught, Apocalypse, and Classic Juggernaut.

But other than these 3, the last 5 standing would be:
5) Magneto
4) X-Man
3) Scarlet Witch
2) Thing or Colossus
1) Namor

*****No, Storm would not be last. Unless you are claiming that she is more powerful then Phoenix, Scarlet Witch, Magneto, Alpha, X-Man, Cable and Franklin Richards, that is...*****

when did I ever say she would be the last? seriously where, because I would like to see my stupid mistake? i never said she would be last, if you properly read my post it says that she would be one of the last, not thee last.

Onslaught, Juggernaut and Thing aren't mutants.

What's onlaught then? cuz here im thinking its Xavier and Magneto put together......

Well Juggernaut technically isnt a mutant, but he is categorized as one.

Franklin Richards with the help of his family.
Magneto and Scarlet Witch (maybe Quicksilver would last a while by association)
Iceman
Jean Grey and most if not all her alternate reality/clone derived kids
I'm not sure if Quentin Quire can die.

They wouldn't be amongst the very last but...
Shadowcat would last a reasonable while.
Emma's interchangeability between being a powerful telepath and having a very durable form would see her surviving a while.
