Looking for absolutely bonkers, top of the food chain MCs

I don't mean a MC that just got an insane cheat, a guy who can punch above his weight class, or someone destined to be stronger than everyone else. I don't want Jake from Primal Hunter, I want the Snake God guy (sorry it's been years since I read this lol) but just maybe not so big in scale in terms of power levels.

If possible I'd prefer Audible recommendations but I'm also fine with Kindle/RR. And bonus points if they just came out of some kind of long form of isolation and the world has forgotten about them. I appreciate y'all 🙏
