Edward Hyde from Volume II of The League of Extraordinary Gentlemen.
He waltzes casually to his fate merrily singing 'You Should See Me Dance The Polka', and gets fried by a massive metal alien tripod. He's not down yet, though. He gets back up-now with HIS SKIN MISSING-and proceeds to crush one of the tripod's legs, sending it toppling to the ground, and then tears off the hatch and EATS THE HEAD of the alien inside. It then takes the combined laser blasts of THREE other tripods, fired in one burst, to finally kill him. As Captain Nemo says: "We have no way of knowing if those things feel any emotion... but we can be certain that Hyde taught them terror."
Can't remember the exact quote (I'm tired and too lazy to go into the next room and dig out my copy of the book), but that's pretty much it. And it sums up Hyde's last stand perfectly.
