10 DC Alternate Universes You Won’t Believe Exist
4. The One Where Everyone's A Fish Person - The Flash #265
A universe that raises many, many questions, and answers none, Earth-265 is a planet where humanity evolved from cetaceans, known better as aquatic mammals such as dolphins and whales.
While this has ample potential for a species of badass looking fish-people, the cetacean-humans are... just blue people, really. They're also weirdly prejudiced against humans who've evolved from primates - possibly because of their lack of sweet gills - and thus hate our heroes when they show up on the scene.
As it turns out, they hate primates so much they also want to destroy the main universe, setting up for one of the most jarring rivalries in comic history.
That said, the potential for some kickass whale folk is still very much potent, so we still have our fingers crossed that the evil fish-people of Earth-265 will surface from the murky waters of their planet to grace us once more.
