Scratchmen Apoo

Stratchmen Apoo  is an infamous music themed pirate from the Grand Line and captain of the On Air Pirates. He is one of eleven pirates who have been referred to as "The Eleven Supernovas" on Sabaody Archipelago whose bounties are higher than 100,000,000 when the Straw Hats arrive in the place.

Appearance
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. Other than these, his most distinguishing attributes are his unique physical characteristics and the objects adorned on him, all of which are music themed or music related. He typically wears a head phone and a chinese garb with kanji "音", which means sound or music, written across the chest area. He also has what seems to be a rose placed in front of his left shoulder. His teeth have a unique look to them that they resemble piano keys. His fighting stance is also music themed as he looks like he's moving his hands in the same way a DJ would move theirs when mixing music on turntables.

Abilities and Powers
Scratchmen Apoo is a martial artist of sorts. His fighting stance generally consists of him waving his hands in front of him like a DJ. Not much much is currently known about his abilities as has so far had not demonstrated any fighting skill as the other Supernovas had save for his brief brawl with Eustass Kid, where the two caused a building to tumble down

Apoo also appears to have a Devil Fruit connected with sound and music. This ability allows him to transform his body into various musical instruments (such as piano keys on his teeth or turning his arm into a clarinet) which he can play. Furthermore, the ability also allows him to release attacks based on various sounds, such as an explosion when he states the word "Don", or a swift cutting effect with "Shan".

History
After a long voyage following one of the Log Pose routes of the Grand Line, Apoo and his crew came to the Sabaody Archipelago to prepare themselves for the New World. While there he had a little squabble with Eustass Kid in Grove 24. Knowing full well what would happen if they caused an incident in Sabaody, Apoo asked Kid to postpone their battle until they got to the New World. The latter fortunately agreed to Apoo's terms. As Apoo continued his stay in Sabaody, he and his crew witnessed some of the cruelty opposed on the inhabitants by the World Nobles. During the little scene with the World Noble, Apoo was suddenly shocked as a then arrived Roronoa Zoro tried to attack the Noble. Fortunately for Apoo and his crew, Jewelry Bonney stopped Zoro and faked the swordsman's death in order prevent an incident from happening. Though danger was averted, Apoo sensed a strong killing intent from Zoro as he witnessed the entire scene.

Upon hearing of Luffy's attack on a Tenryuubito, he seemed reluctant to leave, asking if only the Straw Hats will be targeted by the coming marines. Also, like X. Drake, he seemed eager to find out which Admiral will be dispatched due to the Straw Hat Crew's recent course of action. Despite the best efforts of his crew to get him off the island, Apoo has insisted on seeing the Admiral in action, and feels that he should anger Kizaru before he runs away. Later on, a brawl starts to erupt between Kizaru, Bartholomew Kuma (likely not the real one), Basil Hawkins, Drake, and Urouge, which Apoo excitedly plans to watch.

As the battle unfurls, Apoo gets to witness the thee captains true power, including Drake's dinosaur Zoan, which Apoo states he has never before seen until now. However, he also has to watch Urouge be felled by Kizaru, and Hawkins be blinded by the Admiral before nearly being killed, if Apoo didn't make good on his intentions, by playing on his bodyparts, which were being used as instruments, in order to not only cut Kizaru's right arm off, but also blowing the Admiral up.
