A specific form of Memetic Mutation when the fandom of a series exaggerates a character that is simply Badass, and sometimes not at all impressive, to preposterously epic god-like levels. Despite the name, it doesn't necessarily have to be a widely known Internet meme, and is sometimes just an in-joke among the fan-base. In some cases, the writers agree. Often overlaps with Fan Wank. Fear too the Memetic Molester. In-universe, this can be the result of being Shrouded in Myth, or a God Mode Sue if done poorly. When done to a historical character, it's a Historical Badass Upgrade.
