Donquixote Doflamingo

Donquixote Doflamingo (ドンキホーテ・ドフラミンゴ, Donkihōte Dofuramingo) is one of the Shichibukai, who first appeared in chapter 233 in the manga, and in episode 151 in the anime. He has a former bounty of 340,000,000, the highest bounty displayed so far in One Piece. It is unknown how his bounty became so high.

Personality
Doflamingo seems to have a penchant for drama, as well as a habit of exaggerated posing when giving declarations. He also seems to be the most laid-back of all the Shichibukai. Doflamingo displays rude bravery when he sits on the table during the gathering of the Shichibukai. He also has an odd way of walking.

Like Bellamy, Doflamingo tends to laugh at people's dreams, in preparation for the "New Era." While he appears to regard those weaker than him working mere underlings rather then crew mates, he does still have some pride and a small sense of honor for his old flag and despises the idea of those failing while using it.

Abilities and Powers
He seemingly has the power to control people's bodies like puppets by using some form of psychokinesis (this seems to be dependent on "puppeteer" movement by his arms and fingers), but it is not yet stated whether or not he possesses Devil Fruit powers, or what these powers even are.

Jaya Arc
Doflamingo is initially introduced with his attendance at a meeting held by the World Government as supervised by Fleet Admiral Sengoku after the fall of Shichibukai member Crocodile. After playing with other government agents with his abilities, he states that his "liberation" of other islands was going better than planned and that he only attended this meeting because he was bored. He also noted that Sengoku was speaking too harshly of his liberation, going against his "Great Buddha" image.

Post Skypia Arc
When Doflamingo learned of Bellamy's defeat at the hands of the Straw Hat Captain Monkey D. Luffy, Doflamingo came to Jaya and promptly kicked him out of his crew, forcing Sarquiss' to kill Bellamy in the process. It is as of yet unknown whether or not Bellamy was the only captain under Doflamingo's command.

''The time is almost here. Go and lay the groundwork. A world, where only true pirates can survive will soon be upon us. Those without power, flee while you can. The tide will bring those of unmatched power and the New Era will begin!" Doflamingo's view on the coming of the "New Era".

Curent Events(Spoilers)
He was recently revealed to be the owner of the Human Auctioning House. However he gave it to Disco after it was attacked by the Straw Hat Pirates, stating that slavery was "out" and "smilies" were in.

Trivia

 * Doflamingo is named after Don Quixote, as well as the flamingo, his animal theme (whose brightly-colored plumage is reflected in Doflamingo's style of dress).
 * Doflamingo's flag was the first "smilie" style Jolly Roger seen in the series. Doflamingo also states that slavery is "out", but smilies are "in". The significance of the smilie has yet to be revealed but has appeared in other places since.
