In Naruto, Susanoo is the giant humanoid form made of chakra that Mangekyo Sharingan users such as Itachi and Sasuke Uchiha summon for both attack and defence. The sound associated with its appearance became a recognisable shorthand for overwhelming power among anime fans, and short clips of it spread through soundboards, edits and reaction videos. It remains popular because it instantly signals a major escalation, giving fan edits, gaming moments and memes a ready-made sense of scale without needing context from the original series.
