i believe yes but i'm not sure..this guy is amazing,nothing can stop him!

Mikhail does seem pretty immortal, but I'm sure a grenade underwater would have killed him

I beleve he's alive, but he's just not going to be in the show anymore.

that guys like a cat

I really hope so. He's starting to scare me as much as Ethan.

i htink he has to be, come on if the grenade was strong enough to smash really thick reinforced pressure resistant glass, surely its strong enough to blow his head off which is made from really soft stuff called skin

he better be the bastard that killed my favorite character

i hate him sooo much because he killed Charlie

he's not dead! he's a robot!

i agree with mrsschrute, the only way he dies if by dipping him into molten liquid like at the end of terminator 2 (or was it 1? I can't remember).

lol, i just remembered ethan! those episodes were SO good! - they were terrifying! lol,
and he's survived so much , i just don't know lol, that's why i didnt choose, and also, the writers are so unpredicatible (probably because they dont know what theyre doing) that they probably dont even know themselves lol

He's bloody better be, he took a HARPOON to the chest, if a grenade in his hand doesn't kill him I don't know what else will barring a massive nuclear explosion or Smokey.

unfortunately, he can not die ever

That guy never dies!
