Famous, well-loved stories with ridiculous power and lots of fighting?
Where do we STOP? It's not like this is a short list. We can go back to at least the 19th century, and that's if we DON'T consider mythology at all whatsoever, which carries its own set of things.
Consider anime (and adjacent things that people will get super mad at me if I just call them "anime" even though there's no functional difference). There's dozens of different works out there that you could EASILY use as source material for a D&D-alike game: My Hero Academia, ATLA, YuYu Hakusho, Naruto, Sailor Moon, Cardcaptor Sakura, InuYasha, Pokemon, Digimon, Fairy Tail, Ghost in the Shell, Transformers...frankly, JUST animated action media would furnish opportunities for years, possibly decades.
But there's also plenty of other spaces too. The Underworld film series, for example. Or The Witcher. Or Dragon Age. Or Brian Sanderson's books. He-Man. Or (as much as it pains me to say it) Harry Potter. Or, hell, Lord of the Rings.
Point being, name an action series. You can probably do something D&D-alike with it, at least with a little massaging.
