The 'Mewtwo-shaped Girls' meme is a social media trend that compares certain female body types—specifically those with wide hips and powerful legs—to the silhouette of the legendary Psychic-type Pokémon, Mewtwo. While Mewtwo has been a staple of the Pokémon franchise since Generation 1, this specific internet slang gained traction on platforms like X, TikTok, and Instagram, where users celebrate the 'Mewtwo build' as a striking physique. It serves as a humorous yet appreciative way to categorize body aesthetics through pop culture lenses. The meme often involves reaction images of surprised characters or side-by-side comparisons highlighting the anatomical similarities between the character's iconic design and real-world proportions.
