Oh, sorry.

The simple answer to your question is yes. The Mythic system can be applied to both monsters and player characters, and can be found here. (In relation to player characters, at least. I'm not sure if the same system applies to monsters, or if there's a different way to make a monster mythic)

To sum it all up: What I wrote after the "tl;dr" part of the first long post about Cthulhu's abilities lightly coveres how Mythic works. It's basically a seperate set of levels that add to your power and have their own system. They even have "Mythic Paths" which function like Character Classes, but are tied to the Mythic system as opposed to the expirence/class levels system.

They can be present at any point - for example, a Demigod who's never trained a day in their life may have mythic levels, but few, if any, class levels. A human man with an incredible degree of patience and untold years of travel and training may have no mythic levels, but many, if not the maximum amount of, class levels. And then some - the truly legendary - have maximum levels of both.

Whereas Level 20 is comparable in mastery to Batman, L20M10 is Batman if he was the Chosen One, or the son of a powerful God, or similar.

Perhaps what I had initially said was incorrect; Level 20 is not the hight of power every mortal can achieve, it's the height of power most mortals can achieve. A chosen few can achieve Mythic status and become much greater. And when your powers include things like casual planeshifting, the ability to commune with "the source of your power" (sometimes a God) daily, immunity from essentially everything non-mythic, and eventually even immortality that can only be overcome by execution (or critical hit) with a god-forged weapon, your group can do basically anything.
