The Buff Riku meme originates from the Kingdom Hearts fandom, featuring an edited or fan-rendered version of the character Riku with an impossibly muscular physique. Contrasting his usually lean and agile design, this 'Swole' version became a viral sensation used to represent extreme growth, intimidation, or the feeling of being massively overpowered after hours of RPG grinding. It gained significant traction on platforms like Twitter and Reddit, where fans utilized the image to joke about difficult boss fights or to personify the feeling of absolute confidence. Today, it remains a staple of the gaming community for any situation that requires a comedic digital flex.
