What Is Rule 63 in Internet Culture?

If you have spent any time browsing fandom spaces online, you have likely stumbled across artwork or fiction that flips a beloved character's sex entirely. This widespread phenomenon is formally known as Rule 63.

Originating within informal internet and fandom slang, Rule 63 is the satirical yet remarkably accurate proposition that for every fictional character, a genderswapped version exists. Whether it is turning a historically male hero into a woman or reimagining a female lead as a man, the internet waste no time bringing these alternate designs to life.

While the concept initially spread through viral online memes and community lists, it quickly became a staple of modern fan culture. Today, you can see Rule 63 thriving across multiple creative mediums, heavily driving fan art, fan fiction, and cosplay worldwide.
