Apocalypse v. Apocalypse Battle Royale!

Zeke and his friends are enjoying the city when suddenly, the apocalypse begins. Which one? All of them. Lucky (or unlucky) enough to be chosen as an apocalypse, Zeke sets off to [Devour] his way to the top!

It wouldn't be so bad, but his best friend's out to kill him, that rock has a gun, and everything, literally everything, has gone to hell. Zeke came out here to have a good time, and honestly, he's feeling so attacked right now.

Weak to strong prog fantasy with skills and skill fusion.
