Gecko Moria is a major antagonist in Eiichiro Oda's One Piece, introduced as the ruler of Thriller Bark, the massive ship island crewed by zombies he creates with stolen shadows. Like many One Piece villains, he has a distinctive laugh written as kishishishi, reflecting his name and sly personality. Clips of the anime laugh have circulated for years on soundboards and in fan edits, where the short isolated cackle is reused out of context for any smug, creepy, or scheming character moment online.
