Unkillable...

[SckizoBoy]

Yeah, so, reading through the Wolverine thread... there're quite a few ways to kill him, really, even with 'real world' methods.

Anyway, not the point.

Question: Which fictional character do you think is the most difficult to kill... (or just plain up unkillable) and why?

For one reason or another, I thought of Lucius the Eternal (but get a necron to kill him and problem solved, so never mind).

 

[MercurySteam]

Commander Shepard.

"The Collector killed you once and all it did was piss you off. I can't imagine that it'll stop you this time." - Garrus Vakarian

Not to mention that he will beat the shit out of you if you step out of line:

 

[Dalek Caan]

The Master Chief of course. Has survived 3 Halo's and an Ark. A whole Covenant Armada couldn't take him out. He stole a Covenant Destroyer. Thats how hard to kill he is.

 

[RGman]

God.
For obvious reasons.

 

[Casual Shinji]

Griffith the Absolute One from Berserk.

After becoming a demon god in a seperate dimensional pocket of Hell, he's reborn in the physical world as the anti-Christ, the little s.o.b.

 

[TiloXofXTanto]

Miles "Tails" Prower

Why?

Arguably, the most immortal character of all.

Fawkes from Fallout 3 can take multiple nukes before he goes down, so he may be the most difficult.

 

[9thRequiem]

Alucard from Hellsing.

SCP-682 from SCP.

The One Above All, The Living Tribunal, Jesus. Those are the three that come to mind.
