Wyper

Wiper (ワイパー, Waipā, sometimes spelled "Wyper"; also known as 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 voiced by J. Paul Slavens in the Funimation Dub.

History
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.

Enels Survival Game
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.

Enels Endgame
When he saw Luffy trying to ring the Golden Bell he questioned why as it had no meaning to him. It was then that Robin explained hown they had met a man who was searching for the Golden City, and told Wiper, he was a decendant of Montblanc Norland and that the reason why Luffy was trying to ring the Golden Bell was, that he believed it would tell him that the Golden City was in the sky all allong. Wiper became touched and decided to use the Reject Dial one last time to help the Straw Hats knock over Giant Jack so Luffy can reach Eneru's ship during the climax of the Skypiea arc.

Aftermath
After Eneru's defeat, Wiper sees peace finally come between the Shandians and the Skypieans. Currently, he's helping to rebuild the Shandian's village with the others.

Abilities and Powers
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.

Translation and Dub Issues
Wiper's 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.

Trivia

 * In a recent Japanese Fan Poll, Wiper is currently ranked the 37th most popular character in One Piece.
 * The reason why Wiper got mad at Gan Fall when asked for pumpkin juice was because Wiper took this as a religious insult. Pumpkins were originally introduced by Montblanc Norland to the Shandians and since then pumpkins were regarded as sacred by them.
 * Due to his strength, it was speculated when the Skypiea arc was being written that he would join the crew, despite there being no position that he could fill.
