Nobody's Hero [System Apocalypse LitRPG Progression Fantasy]

There's one firm rule in Central City: everyone dies.  Super strength, invulnerability, regeneration, everything else is on the table. Everything except immortality. After all, if anyone was immortal, then Alpha, the completely-legitimately-elected dictator for life of Central City, could absorb their skill and become dictator for forever. It's a good thing no one is immortal, then. Especially not Levi.  Similar vibes to The Boys, Perfect Run, and Astro City, a satirical dark superhero story with a LitRPG twist!
