[Marvel/DC/etc] Are there other planets out in the multiverse that have a Hero/Villain situation or a lot of attention similar to Earth?

Has this situation been explored? Has it been commented how much traffic Earth gets in terms of all the different systems of the universe appear on the planet? How it is the center of different universal and multiversal events?

Are there other planets and civilizations that has a wide array of super people with different origins and power systems? Like the planet has its regular people, and it has people that are just good with weapons like Hawkeye? Or people just really strong because of experiments like Captain America? Genetic freaks? Tony Stark like inventors? Does the planet have outside alien interference, whether that alien being the hero, or the alien is the origin for one of the people getting powers? Are there magic users? Talking animals? Time travel? Villains? Gods?

My question, being, is there a planet or civilization within the fictions that has a similar stated complexity as Earth, even if the details of which are not as much as Earth’s origin stories? Without it being a mirror Earth?

Superman's run into quite a few heroes from other planets, such as Vartox or the Superwoman of Staryl. Green Lantern's made it clear that, just as there are the Green Lanterns across the cosmos, some of them have their own rogues to worry about.

You've also got the Legion of Super Heroes, an interstellar group of heroes, and their many foes. Other Legion-era teams include the  Uncanny Amazers of Xanthu, where Star Boy hails from, or the Legion of Substitute Heroes. The Amazers were limited to Xanthu, but the Legion and the Substitute Heroes fought crime on many planets. Many of them had powers due to scientific experiments or magic. Villain-wise, you've got the Fatal Five, various crime gangs, the Superman Revenge Squad, and the Legion of Super Villains.

Meanwhile, over in Marvel, you have the Super Skrulls, the Shi'ar Imperial Guard (which consists of superpowered beings drawn from many of their member planets), the Starjammers, the Nova Corps, the Fraternity of Raptors, the Star Lord, Beta Ray Bill, the Guardians of the Galaxy, the *future* Guardians of the Galaxy, the Space Knights of Galador, the Dire Wraiths, and more.

In both universes, space is populated by aliens, and among those aliens you have heroes and villains with all sorts of powers.
