Gyaro
ギャロ
Gyaro is a member of the Macro Fishman Pirates. He is a pop eyed goldfish Fishman. He is a swordsman, reportedly using a style called “goldfish fencing”. Like many characters in One Piece he has a distinct laugh: eheheh. [1]
He was taken out with one punch along with Macro and Tansui by the newly freed Hachi.
