The 'Everything Is Canon' meme originated from the official Sonic the Hedgehog Twitter account in 2021, which responded to a fan query by declaring that all versions of Sonic's history are officially canon. This chaotic approach to franchise lore quickly resonated with internet culture, especially among fans of series with complex timelines like Marvel, DC, and Doctor Who. It is commonly used to jokingly validate absurd fan theories, crossover ships, or contradictory plot points within a fictional universe. The phrase has become a shorthand for the modern multiverse era of storytelling, where no piece of media is ever truly discarded or ignored.
