Wyper

Wiper (ワイパー, Waipā, sometimes called Wiper the Berserker) is the leader of the Shandian warriors fighting to take Upper Yard back from Eneru, he fights with a Burn Bazooka. He is a direct descendant of Calgara, inheriting his violent tendencies. Wiper is very rough around the edges and has always hated both the Skypieans (despite Gan Fall's best efforts to attain peace between the two people during his time as "god") and anybody from the seas. He fought against Monkey D. Luffy during the survival game yet their match ended in stalemate. Later, he, along with Nico Robin, Roronoa Zoro, Nami, Eneru, and Gan Fall, survive Eneru's survival game, but Eneru defeats Wiper with his Goro Goro powers when Wiper refuses to join him. Wiper uses a Reject Dial, a powerful Dial weapon that causes great damage to both the enemy and the user, for the kill. However, Eneru simply uses his powers to restart his own heart and strikes the Shandian warrior down once more. Later he uses it for a third time that day-he supposedly should have died after the second use-to help the Straw Hats knock over Giant Jack so Luffy can reach Eneru's ship during the climax of the Skypiea arc.

After Eneru's defeat, Wiper sees peace finally come between the Shandians and the Skypieans. Wiper fights using a Burn Bazooka and a Reject Dial, though he is skilled at close combat, mainly involving the use of Skate-type Wavers to boost his kicks. Currently, he's helping to rebuild the Shandian's village with the others.

In a recent Japanese Fan Poll, Wiper is currently ranked the 37th most popular character in One Piece.

His name was romanized in One Piece: Grand Adventure as Wyper, but in One Piece: Pirates Carnival (and possibly the dub), he was given a name change of "Wyler". But due to the fact his name was Wyper in One Piece: Grand Adventure may mean that he will be called Wyper in the dub.
