Batman went from fighting Joker, Toy Man, Riddler, Captain Condiment, etc to throwing hands with Darkseid and Superman
The rules are he's a human fighting other humans. Superman is superhuman so he's not fighting the Joker and Penguin.
I swear a kid must have told a Superman writer that Surfer was faster so he went and wrote a story to fix that. People eat that BS up too like dude in here talking about Superman rips dimensions apart and destroys planets by jumping
How is he not decimating earth?
This is why I stick to manga. American comics switch writers, books go on forever, main characters don't age or die (unless it's a gimmick to sell books), they do shyt for cool points at the expense of the narrative, etc.
