The 'Canon vs. Fanon' meme is a popular trope within online fandoms, particularly on platforms like Tumblr, Twitter, and TikTok, used to highlight the discrepancy between a character's actual personality in official media and how they are reimagined by the fan community. Often appearing as a side-by-side comparison, it contrasts the gritty or realistic 'Canon' version of a character with the exaggerated, soft, or wildly different 'Fanon' interpretation. This meme serves as a commentary on the power of fan culture and headcanons, allowing fans to mock common clichés, ship dynamics, or the collective drift of a character's identity away from their original source material.
