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 is strong and is capable of wielding two swords.

He seems to be quite well known, Donquixote Doflamingo knew who he was when he encountered him

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 the death of Whitebeard. He joins his crewmembers ready to fight Akainu.
