Donquixote Doflamingo, nicknamed "Heavenly Yaksha", is the captain of the Donquixote Pirates. Prior to his imprisonment, he was a member of the Seven Warlords of the Sea with a frozen bounty of 340,000,000, as well as the most influential underworld broker under the codename "Joker". He is also a former World Noble, descended from the Donquixote Family.
He is the first son of the late Donquixote Homing and the older brother of the late Rosinante, both of whom he killed out of feeling betrayed by them.[18][17] Doflamingo became the King of Dressrosa after taking the throne from Riku Doldo III eight years before the start of the series. He ruled the country tyrannically until he was stripped of his positions as a Warlord of the Sea and king after he was defeated by Monkey D. Luffy near the end of the Dressrosa Arc. After Doflamingo was arrested by Admiral Fujitora along with most of his crew, he was locked up at Impel Down and placed in Level 6. Vegapunk later cloned Doflamingo as one of the Seraphim to replace the Warlords.
He is a major antagonist in the Marineford Arc where he took part in the Summit War of Marineford and sided with the Marines, along with most of the other Warlords of the Sea, and the main antagonist of the Dressrosa Arc and the Dressrosa Saga as a whole, being the impetus for the entirety of the saga's events.
Doflamingo ate the Ito Ito no Mi, a Paramecia-type Devil Fruit which allows him to create and control strings. His strings are incredibly durable and razor-sharp, making them able to cut, pierce, block, bind, or bash his opponents. The strings are extremely thin, and some may even be invisible, making it almost impossible to notice and avoid them.
The strings have incredible cutting power, which allow Doflamingo to effortlessly slice off his opponent's body parts and cut weapons apart. He could even use his strings to slash a gigantic meteor into tiny pieces. Depending on how he uses his power, Doflamingo can go as far as to cut an entire country to ribbons. He can also shoot strings at his opponent like a bullet, giving them great piercing power.
He can combine and compress a large number of strings into rope, allowing him to attack with blunt force. He can also use strings to create an immensely sturdy protective barrier web, which can halt debris and powerful Haki-enhanced blows in their tracks. In the case of an emergency, Doflamingo can use strings to repair his internal organs as a crude way to staunch the worst effects, though it is not considered actual healing or regeneration.
Doflamingo can attach strings to his opponent's body, allowing him to puppeteer their body; he can make his victims move to his will by moving his fingers accordingly. Doflamingo mainly uses this power to force comrades to fight (and even kill) each other, while Doflamingo himself sits at the sidelines and watches. His victims are unable to resist his puppet strings and are therefore rendered completely helpless. He has shown himself capable of controlling large amounts of people at the same time without any apparent effort. This ability is even powerful enough to stop the incredibly physically strong "Diamond" Jozu in his tracks.
He can also travel in midair by attaching his strings to clouds, as seen when he did so to cross over the seas to reach Punk Hazard from Dressrosa.Currently the only known limitation of his sky traveling ability is that he cannot use it where there are no clouds, meaning that if the sky is clear, he loses his ability to fly.
Doflamingo has achieved Devil Fruit Awakening, granting him the power to transform non-living things in his surroundings into strings that he can freely manipulate.
Doflamingo is a capable user of Haoshoku Haki, as shown when he knocked out the majority of the G-5 Marines at Punk Hazard. Doflamingo's Haoshoku Haki first awakened when he was around ten years old, when being pursued again by North Blue citizens who tried to continuously torture his family in revenge, knocking them all out, thus saving him.In a clash with Luffy, their Haki created a notable effect similar to lightning.
Doflamingo is an extremely skilled user of Busoshoku Haki, which he used conjunction with his Devil Fruit ability to cut Smoker, a Logia user, seriously wounding him at Punk Hazard. He was also able to instinctively harden parts of his body and clothing enough to resist Luffy's Jet Gatling without any visible injury and counterattack with a Haki-enhanced punch that injured Luffy and sent him flying back a considerable distance. His Busoshoku Haki is strong enough to counter Law's spatial slicing powers, though it was still not strong enough to defend against the sharpness of Law's sword, as he cut his hand slightly after grasping the blade.
