Ohm

Seiyuu: Eiji Takemoto

Skybreeder Ohm (スカイブリーダー・オーム, Sukaiburīdā Ōmu) the fourth priest, punishes criminals with the Ordeal of Iron, where the victims are cut into pieces by barbed wires when they step onto hidden panels. He attacks with a sword made of iron cloud that has a Dial in it that allows him to turn the sword's blade into any shape including a wall or a whip. He is defeated by Roronoa Zoro who, despite Ohm using Mantra to predict his attack, waits for him to attack to give away his position. He then cuts through Ohm's sword using the 108 Pound Cannon attack to defeat him. His ordeal has a 0% chance of survival.

He's a playable character in One Piece Grand Adventure.
