Atmos

Atmos is the commander of the 13th division of the Whitebeard Pirates. He is known as the Water Buffalo.

Appearance
Atmos is a huge man, roughly the size of Jozu, whose choice of clothing he somehow mirrors: he is dressed in sleeveless gray and golden armor, and wears an old-fashioned Asian-themed gray helmet that has bull horns on it, that makes him resemble a water buffalo, as per his epithet. He has long, mane-like black hair, reaching down to his waist, and his beard is just as long. He has two teeth resembling those of a walrus, but square-shaped and pointing upwards. On each of his arms, he bears the tattoo silhouette of Whitebeard's Jolly Roger.

Abilities and Powers
As the commander of the 13th division of Whitebeard's crew, Atmos has command and responsibility over the pirates within his division. He seems to be quite well known, as Shichibukai Donquixote Doflamingo knew who he was when the two encountered each other on the battlefield.

Weapons
Atmos carries around two large swords, and can apparently deals devestating blows with them, as seen when, under Doflamingo's control, he attacked his own men.

Marineford Arc
Seeing Doflamingo laughing at Oars Jr.'s sacrifice, Atmos and his men decided to confront the Shichibukai. However, before they could do anything, Atmos found himself being controlled by the Shichibukai. Unable to control himself, Atmos was forced to fight his own men.

Eventually he was freed from Doflamingo's control, and continued on with the battle. He made it onto the black paddle ship and was later seen standing next to his fellow Whitebeard Pirates.

Atmos is seen later along with some other division commanders and Jinbei taking a defensive line behind Whitebeard to cover him. He is last seen along with Marco and Vista, looking in shock as Akainu's fist penetrates Ace's body. He later cries and mourns over the death of Whitebeard. He joins his crewmembers, ready to fight Akainu. This battle was never shown, but he is shown to be unharmed later on. Upon the arrival of Shanks and Sengoku calling the war coming to a close, he and the rest of Whitebeards crew left.

Post-War Arc
He, along with the rest of the crew attended the funeral of Whitebeard and Ace on a undisclosed location somewhere on the Grand Line.
