The 'Let's See Who This Really Is' meme originates from the classic animated series 'Scooby-Doo, Where Are You!', specifically depicting the recurring climax where Fred Jones removes the mask of the episode's villain. Online, this four-panel template is used to expose the 'true identity' of a concept, brand, or trend that is pretending to be something new or different. It serves as a visual metaphor for corporate rebranding, political shifts, or simply pointing out that two seemingly different things are actually identical. Its longevity in internet culture stems from its perfect encapsulation of cynical reveals and the nostalgia of the mystery-solving gang.
