The Rasengan was introduced in Masashi Kishimoto's Naruto manga and anime as a signature technique created by Minato Namikaze and mastered by Naruto Uzumaki. Formed by spinning chakra into a dense sphere, it became one of the series' most recognizable attacks. Clips of its charging sound spread through anime edits, AMVs and soundboards in the 2000s and 2010s, alongside other staples like the Naruto Sad Song. It remains popular because the rising swirl instantly signals effort and power without needing any visual context.
