Kage Bunshin no Jutsu is the Shadow Clone Technique from Naruto, the long-running manga and anime created by Masashi Kishimoto, where Naruto Uzumaki creates solid copies of himself to outnumber an opponent or complete several tasks at once. The technique became one of the series most recognisable signatures, and its accompanying sound has travelled far beyond the show through anime edits, gaming videos and short-form memes. Creators still use it because the idea of suddenly having extra versions of yourself is instantly understood, funny and easy to reuse.
