Grima (Fire Emblem Awakening)- Can only be killed by a wielder of the Falchion... or himself.

Nyx (Persona 3)- Can't even die unless humanity overcomes its collective desire for Death.

Any Persona character with an Omnipotent Orb- Immunity to every kind of attack. The only exception: Almighty (specific non elemental) attacks that ignore durability.
