Gecko Moria is a major antagonist in Eiichiro Oda's One Piece manga and anime, introduced as the captain of the Thriller Bark Pirates and one of the Seven Warlords of the Sea. His unique laugh style, written as kishishishi, is a trademark shared by many One Piece villains who each have a personal laugh pattern. Clips of Moria's laugh spread through anime edits, soundboards, and reaction videos, where its theatrical tone made it a shorthand for an overconfident bad guy.
