If we look to something like manga, I'd say that someone like Kenshiro is definitely a "superman" archetype. He can almost always win or at least clutch one even against stronger enemies. But he's not invincible and he has to grow in power over the course of the story, and it's not really treated as a grimdark for-the-sake-of-edge story either for all the gore in it. It's about overcoming callousness with compassion and is very hopeful in tone.
That doesn't mean you have to directly remake him in a superhero setting with martial arts and stuff, but it does mean you can have a "strongest superhero" that isn't a flying brick direct superman clone.
