Thanos
Thanos claims millennia of existence, having survived the fall of Titan and accumulated power across cosmic epochs. His physical longevity far exceeds any human technology, with biological processes apparently arrested at peak intimidation capacity.
However, his functional longevity proved remarkably limited. Active engagement with the broader universe lasted approximately a decade before terminal retirement via decapitation. His legacy persists in cultural memory, but his physical presence was eliminated with surprising efficiency by a man with an axe. Immortality, it transpires, has its limits.
