Ryomen Sukuna is the King of Curses in Jujutsu Kaisen, created by Gege Akutami as a manga in 2018 and adapted into an anime in 2020, where he is voiced in Japanese by Junichi Suwabe. His laugh clips spread through anime edits, TikTok and soundboards because the performance captures his sadistic personality in a few seconds. Fans pair it with other iconic shonen moments like the Mangekyo Sharingan reveals in Naruto, using the sound to signal overwhelming cursed power, possession by Yuji Itadori's inner demon, and a fight turning hopeless.
