Gear Fourth is a transformation used by Monkey D. Luffy in One Piece, the manga and anime series created by Eiichiro Oda. The form debuted in manga chapter 784 in 2015 during Luffy’s battle with Donquixote Doflamingo, then appeared in anime episode 726 in 2016. Its combination of Haki, inflated muscles, speed, and exaggerated movement made it a recognizable power-up across anime fan communities. Gear Fourth audio remains popular in edits because it quickly signals escalation, determination, and overwhelming strength.
About this sound
A dramatic One Piece audio clip built around Monkey D. Luffy's Gear Fourth transformation, used for anime edits, power-up reveals, and battle memes.
This short clip captures the heightened energy associated with Luffy entering Gear Fourth in One Piece. Its dramatic anime delivery and power-up atmosphere make the transformation feel larger, faster, and more dangerous than an ordinary attack. The audio works especially well when a character reveals unexpected strength or a video suddenly shifts into an intense confrontation. For viewers familiar with the series, it immediately recalls Luffy’s inflated, Haki-covered fighting form; for everyone else, it still communicates a clear surge of power and determination.
