The Dragon Radar first appeared in Dragon Ball, the manga and anime series created by Akira Toriyama, where Bulma builds the handheld device to locate the seven Dragon Balls scattered around the world. Its short electronic ping became closely linked to searching and discovery in the series, and fans later lifted the sound for edits, reaction videos and gaming montages. Because the radar is so central to the early adventures, the blip still works instantly for Dragon Ball fans and for viewers who simply recognise it as a found-it cue.
