Henshin means transformation in Japanese and became famous through tokusatsu television starting with Kamen Rider in 1971. Heroes would strike a pose, shout the word, and change into their suited form accompanied by electronic effects and music. The format spread through Super Sentai, later adapted as Power Rangers, and into wider anime culture. Online, the Henshin sound is now used far beyond its original shows, as a meme cue for any dramatic change, from putting on sunglasses to leveling up in a game.
