Description
Odr, also written as Ozu in some variant spellings, is another name for the character more widely known as Oars, an ancient giant who appears in the anime One Piece. He is commonly referred to by the epithet Oars the Continent-Puller and was also known by the title the Devil.

In terms of background, Oars lived roughly five hundred years before the main events of the story. He belonged to the Ancient Giant race, and his physique was several times larger than that of an ordinary giant. He had two large horns and long yellow hair that flowed from his head down his back. According to the legends recounted in the series, he conquered countries and physically hauled entire islands across the sea, dragging the captured lands back to his own territory to build what was described as a nation of villains. He eventually died in a frozen region known as the Land of Ice at the age of 159, leaving behind a colossal corpse that became part of his fearsome legend.

During the Thriller Bark arc, the Warlord of the Sea Gecko Moria recovered the body of Oars and used the powers of his Shadow-Shadow Fruit to reanimate it as a special zombie, designated number 900 within his zombie army. Moria placed the stolen shadow of Monkey D. Luffy inside the giant's body, which shaped the revived creature's fighting style around Luffy's rubber-based techniques. Because the corpse carried Luffy's shadow, the zombie could unleash oversized versions of Luffy's Gum-Gum attacks, such as the Gum-Gum Pistol, the Gum-Gum Gatling, and related moves, making him a uniquely powerful opponent for the Straw Hat crew.

As a character, the revived Oars has no independent personality. He is presented as a mindless berserker who acts on Moria's commands and fights on instinct, with no speech, personal goals, or will of his own. The historical Oars, by contrast, is remembered through legend as a ruthlessly ambitious ancient giant whose motivation was to gather conquered lands into a single country of villains, an ambition that defined his reputation as the Devil. The contrast between the legendary figure who once shaped the world and the empty puppet revived centuries later is central to his presence in the story.

In terms of abilities, the zombie Oars possessed tremendous physical strength, powerful enough to knock out large groups of enemies with a single blow, including whole units of Moria's zombie army. Despite being larger than a normal giant, he was remarkably fast and agile, able to evade several consecutive attacks from the entire Straw Hat crew and even perform the high-speed movement technique known as Soru. As a reanimated corpse, he felt no pain, which made him extremely difficult to incapacitate. His main limitations were his dependence on Moria's power and the fact that his body could still be overwhelmed through coordinated, sustained force.

His role in the story is that of the central physical threat during the Thriller Bark arc. The Straw Hat crew, cooperating with one another and with the island's inhabitants, had to stop the rampaging giant in order to recover Luffy's shadow. After an extended battle, the combined efforts of the crew succeeded in shattering every bone in his body, ending the zombie's rampage. His defeat cleared the way for the final confrontation with Moria and for the recovery of the shadows that had been stolen from the crew.

In terms of key relationships, Oars is directly connected to Gecko Moria, who turned his corpse into a weapon, and to Luffy, whose shadow animated him and dictated his combat style. He also stands as the major obstacle faced by the Straw Hat crew in this part of the series. His legacy extends beyond Thriller Bark through Little Oars Jr., a giant who appears later in the story and is described as a descendant of Oars, carrying on the name and legend of the ancient giant.
