Metron is a seeker of knowledge. He takes no sides, and therefore rarely ever involves himself in battles/conflict... He's beyond that kind of thing.
But given the universal+ levels that all noteworthy New Gods are currently being portrayed at, I wouldn't at all be surprised if he were beyond RKT. There's really no way of knowing at this point, though. /shrug
Although I will say that he seems completely unharmable while sitting on the Mobius Chair(unless attacked by Mobius himself, of course.)
There are other feats as well, like him weakening the Source Wall and banishing the Black Racer. It has also been stated that his power is "limitless".
I thought he (Metron) was like an abstract entity? Rune King Thor is at least equal to or above Odin who is the very top of his weight class which puts an omniscient RKT at maybe very bottom of abstract tier? I dont know, wanna go for my boy Thor but unlike some people I dont just automatically vote for my fav.
So..those scans or nice but Rune King Thor could tank a superman punch and whatever Atom dished out with utter ease. And Thor is a warrior while Metron is more akin to a Watcher. But i feel like Metron should still be quite a bit above him in overall power output.
Metron 6-7/10. Unlesms he has no answer for Thor's omniscience and time travel then Thor10/10
