The Fat Pikachu meme, often referred to as 'Chonky Pikachu' or 'Classic Pikachu,' pays homage to the original 1996 design of the iconic Pokémon from the Red and Blue era. Unlike the modern, more athletic version of Pikachu, the original artwork featured a rounder, more rotund silhouette. This version resurfaced in internet culture as a symbol of nostalgia and a relatable reaction image for overeating or feeling 'extra.' It gained massive traction on platforms like Reddit and Twitter when fans began comparing the original design to the current one, often jokingly claiming the 90s version was at 'peak performance.' Whether used for wholesome nostalgia or self-deprecating humor about body weight, Fat Pikachu remains a beloved staple of the Pokémon meme community.
