Is there a capeshit character who's only power is invincibility? like they're completely unremarkable in every other aspect, no super strength, no flight, no lasers, no heightened intellect, no bells or whistles. Not even accelerated healing per se, don't need to heal if you're completely invulnerable to physical harm in the first place.
I feel like theres interesting story potential in that.
There was a character in JMS' series, Rising Stars, like this. He was totally invulnerable, nothing could hurt him, but the same power that make him impervious to any physcial harm meant he could never feel the touch of another person. He tries to become some sort of celebrity, but fails miserably, and so takes solace in eating, since taste is one sensation he still possesses. He becomes a fat, miserable, lonely fuck. Then someone murders him by suffocating him.
