When do Wonder Woman Superman and Batman rule the Earth?

There is no single, definitive instance where Wonder Woman, Superman, and Batman rule Earth. They are fictional characters, and their stories and timelines vary depending on the comic book series, movie, or other media they appear in.

Here are some possibilities, but keep in mind these are just hypothetical scenarios:

* In a dystopian future: A story could depict a future where the heroes are corrupted or forced into power, ruling Earth with an iron fist.

* A temporary situation: Perhaps there's a story where a temporary event, like a global crisis, forces them to take control of Earth. However, this would likely be a temporary measure.

* A "what if" scenario: A story could explore the possibilities of these heroes becoming rulers, but it wouldn't necessarily be a definitive canon event.

Overall, while it's an intriguing thought experiment, it's important to remember that these characters are typically portrayed as protectors of Earth, not its rulers.
