Ideo's Manga Color Scheme

Ideo's color scheme in the manga.

Ideo has dark purple hair (black in the manga) pulled back into a tight ponytail and a dark purple beard (also black in the manga). He has a widow's peak, sharply edged facial features, and dark eyeliner surrounding his eyes, with large eyelashes on his lower eyelid, and a bulging vein on the side of his head. As a member of the Longarm Tribe, he possesses very long arms, with an extra elbow joint; unusually for a Longarm, he keeps the extra joint extended past his shoulders over his head.[4] He has his ear pierced three times and has four black crosses tattooed on his chest.

In the manga he is shown sporting a black jacket, with a white stripe coming down each arm. He also wears black shorts that have a white stripe coming down each leg, a large belt, and kneepads. Ideo also has bandages wrapped around his calves and feet, along with light colored gloves.

His anime appearance is largely the same, with the exception of the stripes on his arms and legs. In the manga they are depicted as being white while the anime portrays them as red.


He is confident enough in his abilities to enter the Corrida Colosseum tournament. During the Block C battle royale, he states his one desire: to become stronger, which is the main reason he wants to win the Mera Mera no Mi.[3]

He can also be quite merciless, as he had no qualms attacking an already unconscious opponent.[3]

Unlike most of the people who were freed from Sugar's curse, Ideo is not shown to be swayed by greed as he chose to fight the Donquixote Pirates instead of their enemies.

Abilities and PowersEdit

Ideo is a XXX rank boxer, and a member of the Longarm Tribe. He uses a punching technique wherein he delivers a hit which explodes on impact. His punches are apparently powerful enough to send Hajrudin's massive body flying with a single strike, although it should be noted that the giant was already unconscious at that point.[3]

Being a member of the Longarm Tribe gives him arms with an extra joint and length. He kept the extra joints quasi-hidden by extending them past his shoulders, allowing him to hide them for a surprise attack, stretching them out when necessary for the extra reach and strike;[4] this compression of his shoulders gives him the extra strength to add that explosive power to his punches.[3]

He was confident of his own strength as he entered as a contestant in the Corrida Colosseum. He is strong enough to handle the New World and go toe to toe with Sai, who was personally selected to be the Commander of the Happo Navy by Don Chinjao. However, he was no match for Chinjao himself as he was cast aside by him with ease.[5] The anime revealed that he remained conscious in the water after being knocked out of the arena, which implies he has immense superhuman durability and that he lacks a Devil Fruit power (since he did join the tournament for the fruit).


Destruction Cannon

Hakai Ho

  • Hakai Ho (破壊砲 Hakai Hō?, literally meaning "Destruction Cannon"): An explosive punch that is Ideo's signature attack, and the source of his epithet. It was first seen when Ideo punched the unconscious Hajrudin out of the ring in the Block C battle royale,[3] and named when he participated in the battle against members of the Donquixote Pirates.[6] According to Gatz, the explosive power of the attack comes from Ideo's oddly-shaped shoulders,[3] which are actually his Longarm Tribe joints compressed past his shoulders.[4]



Sometime in the past, he became known as the 2 time (V2) champion of the New World Central Fighting Tournament.[7]

Dressrosa ArcEdit

Ideo entered the Corrida Colosseum to compete for the Mera Mera no Mi. For the battle royale, he was placed in Block C.[1]

After Lucy defeated Hajrudin, Ideo walked over to the giant's prostrate body, stating that this place is a ring and that he can sleep elsewhere, before using his formidable punching powers to knock the giant out of the ring, highly surprising Gatz and the spectators. After this show of strength, Ideo announces his desire to grow even stronger by eating the Mera Mera no Mi, before proceeding to attack more of his fellow Block C fighters.[3]

Chinjao Punches Ideo

After Sai defeated the Funk Brothers, Ideo was then locked in combat with him. The two fought evenly, exchanging blows with each other. The boxer used his exploding prowess while the Chinjao Family member utilized his Hasshoken technique. They clashed until they were caught in the middle of Lucy and Chinjao's feud. Before Ideo can so much as react, an irate Chinjao easily clobbered and knocked him out of the ring, much to Gatz and the spectators' utter shock.[5]

He later went to the underground medical treatment facility to receive treatment for his injuries. While waiting for his turn, he was annoyed with Sai yelling at a doctor concerning Chinjao.[8] Shortly afterwards, he was tricked and thrown into an underground dungeon, alongside Kelly Funk and Boo, where they joined the other disqualified participants.[9]

He was later transformed into a toy and forced to work in the underground trade port. When Sugar lost consciousness, Ideo returned to his original form.[10]

After Doflamingo trapped Dressrosa in his "Birdcage", Ideo and the other colosseum fighters escaped to the surface through an opening created by Pica when he rearranged the land with his ability.[11]

Luffy and the Corrida Colosseum Gladiators Going After Doflamingo

Ideo with Luffy, Zoro, Law, Ucy and the other Corrida Colosseum combatants are on their way for Doflamingo.

When he found Luffy, Zoro, and Law, Ideo stated that he will defeat Doflamingo. He joined forces with Luffy's group alongside the Chinjao Family, Hajrudin, Suleiman, Fighting Bull, Blue Gilly, Cavendish, Abdullah, Jeet, Orlumbus, Elizabello II, and Dagama. When some of the former toys came for the heads of Luffy, Zoro, and Law, Ideo and the allied colosseum fighters fought them off. They later marched towards the royal palace and began to battle against Pica.[12]

When Pica attacked, Chinjao and Elizabello II shattered his stone hand, enabling the group to move forward.[12] Ideo and the other allied fighters fought through Doflamingo's troops. Pica then attacked with his other arm, causing Ideo and some of the other allies to fall back. After avoiding Pica's strike, they were surprised to see Luffy, Zoro, Law, Abdullah, Jeet, and Fighting Bull climbing on Pica's arm. They were also amazed when Luffy shattered Pica's stone head. When Pica's giant stone body stopped moving, Ideo and his allies continued on with their assault.[13]

With Zoro fighting Pica and Sabo fighting the Marines, the colosseum fighters charged up the new King's Plateau and easily defeated the Donquixote Pirates' troops standing in their way.[14]

Dellinger Defeats Ideo

Dellinger defeats Ideo.

After reaching the second level, the colosseum fighters were confronted by four of the Donquixote Pirate officers. The colosseum fighters later banded together to create an opening for Luffy and Cavendish.[15]

Later on after Dellinger defeated Blue Gilly, Ideo faced off against Dellinger.[16] Ideo attempted to attack with an explosive punch, but Dellinger easily dodged it.[17] When he was distracted due to Pica changing the shape of the plateau, Ideo managed to land a hit on him.[18]

Dellinger retaliated by puncturing a hole on Ideo's stomach. Before Dellinger left the second level to assist Gladius, Ideo grabbed ahold of him. Dellinger took off his hat and revealed his fangs, which he used to deal the finishing blow to Ideo.[4]

After most of the Donquixote Pirates' officers were defeated, Pica preyed on the injured, including Ideo.[19]
