Scratchmen Apoo

Scratchmen Apoo, also known as "Roar of the Sea", is a longarm and an infamous music-themed pirate and captain of the On Air Pirates. He and his crew originated from the Grand Line. He is one of twelve pirates who are referred to as the "Worst Generation". After the timeskip, his bounty has been raised from Beli198,000,000 to Beli350,000,000.

Being of the Longarm Tribe from the Grand Line, one of Apoo's distinguishing traits is his incredibly long arms. Each of these long arms possesses two elbow joints instead of just one, making them much longer than a normal person's. These arms make it possible for him to utilize his Devil Fruit powers without the need to contort the said limbs, whenever he converts them into makeshift instruments.

Apoo also has a rather broad chest cavity, which may aid him in producing deep and bellowing drum-like sounds. Apoo's lower jaw is also somewhat wider than the upper half of his face, similar to Itomimizu of the Foxy Pirates. Besides these, his most distinguishing attributes are his unique physical characteristics and the objects adorned on him, all of which are music themed or related. His teeth have a unique look to them as they resemble piano keys. His fighting stance is also music themed as he appears like he's moving his hands in the same way a DJ would move theirs when mixing music on turntables.

He wears a set of orange headphones with his name on either side over his ears and hairstyle similar to Jabra's, where the hair on his scalp has been pulled tightly so that his roots resemble lightning patterns. A red Chinese garb with crew's Jolly Roger 音 ( oto?, "sound" or "music"), at the center of a large flower-like print splayed across the chest area, as well as on his back. Apoo also has a yellow scarf around his waist. He also has what seems to be the design of a green rose sewed on front of his left shoulder.

In SBS Volume 64, Oda drew the Supernovas as children. Apoo is shown with significantly shorter hair and a rounder face. His hair was also combed into a pompadour in the front, with his braid in the back. His attire was a less elaborate shirt and bow tie. His teeth also lacked the dark markings that make them resemble piano keys.

After the timeskip, he wears a set of black headphones, and changed to a different garb that has the kanji moved to the right side of his pants, ropes as buttons for the shirt, and epaulets on his shoulders.

Apoo seems to be a passive individual who would not seek to harm others without a good reason. As a result, he is normally defensive during confrontations as seen in his postponed brawl with Eustass Kid at a Sabaody Archipelago bar. Despite this, Apoo can be very ambiguous at times, meaning he cannot deny himself as audience to a good brawl should the opportunity presents itself. When facing an opponent that's too strong for him, he prefers to run away. However, he enjoys provoking and taunting his enemies before leaving.

He also proved to be quite perceptive, since he claimed to have sensed an immense murderous intent momentarily emitted by Roronoa Zoro, shortly before Zoro attempted to attack the World Noble Saint Charlos after the latter attempted to shoot the former. He appears to be reckless and overconfident, as shown when he believed that he could attack Kizaru at Sabaody Archipelago and run away, only to be pummeled to the ground by the Marine admiral.

He hates it when someone tells him the obvious, such as when a crew member stated that the crew was running in the air, while they were running away from a pack of savage boars in the New World.

After the timeskip, Apoo seems to have become very cautious, believing that when summoned by an enemy he should be ready to fight, and when Killer invited him to discuss the possibility of an alliance, Apoo believed Kid to be hiding a sniper, which resulted the On Air Pirates captain to wreak havoc on Kid's base and attacking one of his crew members.
