The Which Character Are You? meme format stems from the long-standing internet tradition of personality quizzes and alignment charts, where users categorize people or fictional characters into specific archetypes. Unlike traditional quizzes, these memes are often satirical, featuring absurd or highly specific traits like 'eats pizza with a fork' or 'has 500 unread emails.' They gained massive popularity on platforms like Tumblr and Twitter as Tag Yourself memes, serving as a social tool for friends to bond over shared quirks. Today, the format is used by every fandom and friend group to humorously define their social dynamics through a visual grid of identifiable tropes.
