Dragon Ball Z, the anime series adapted from Akira Toriyama's Dragon Ball manga, made the Saiyan power-up scream one of anime's most recognisable sounds. Saiyans are a warrior race in the series, and characters scream for extended stretches while gathering ki energy before transformations and major attacks. Clips of those scenes circulated online as reaction audio and in fan edits, where the scream became shorthand for charging up, raging, or going all out. Its length and intensity keep it popular for anime memes and battle edits today.
