Last Son(s) of Earth

Marvel earth.

This presupposes every earth born hero/villain/character is on earth at the same time, and the planet just...blows up.
No warning. From one second to the next, boom.

How many if any earthlings could survive and make it to some other inhabited world?

Marvel:
Thor
Hulk
Hype
BM
Pym if in his lab

Mr. I?

Hyperstorm survives, midnighter, wolverine, etc.

Midnighter?

Yeah, Mr. Immortal would survive. I dunno if he'd make it to another uninhabited world - I suppose that could be possible if the survivors band together after the explosion.

Same goes for Kitty Pryde.

Kitty? Is she permanently phased? I can never remember. I know she wouldnt need to breathe.
