Donquixote Doflamingo

"Pirates are evil? The Marines are righteous? These terms have always changed throughout the course of history! Kids who have never seen peace and kids who have never seen war have different values! Those who stand at the top determine what's wrong and what's right! This very place is neutral ground! Justice will prevail, you say? But of course it will! Whoever wins this war becomes justice!"

- Doflamingo at Marineford

Donquixote Doflamingo was the main antagonist of the Dressrosa arc/Pirate Alliance saga of the One Piece manga/anime. He is the captain of the Donquixote Pirates and was the king of Dressrosa before his defeat by Luffy and Law. Formerly the most influential underworld broker, Doflamingo's defeat and capture sent shockwaves throughout the New World, enraging his affiliates, including one of the Four Emperors, Kaido.

History
Born a Celestial Dragon in the "Holy Land" of Mariejois, Doflamingo is the descendant of one of the royal families that helped form the World Government. At the age of eight, his father, Donquixote Homing, decided to abandon the splendor of Mariejois and live as commoners in an undisclosed northern country. Still accustomed to his old lifestyle, Doflamingo retained his entitlement and expected civilians to bow to him. Homing's attempt at integration became a fight for his family's lives, as their identity as World Nobles placed them under ruthless persecution by the country's inhabitants, as they burned the Donquixote mansion and drove the family into a makeshift home amidst garbage. Doflamingo and his younger brother, Rosinante, soon took to eating trash. Homing, regretting his decision, contacted the World Nobles in Mariejois as a plea for help, only to be rejected; this greatly upset Doflamingo, as he had overheard the conversation. Not long after, as a result of the family's horrid living conditions, Doflamingo's mother died of illness.

The embittered civilians eventually tracked down the family's refuge. Doflamingo, Rosinante and Homing were lynched and beaten severely; although they ultimately survived. While undergoing torture, Doflamingo swore to kill everyone; horrifying his brother, father and their captors.

Quotes
"Who's going to be happy seeing you safe and sound after running around like a coward? If you can't cut down your foe, take a blow and bleed for yourself! Every human being... even the most pious saint, harbors a latent streak of barbarity that surfaces when he sees blood! Blood and death! This is entertainment!"

"The fact that you miserable brats thought, for even an instant, that you could actually beat me is the highest disgrace! Understand this. I am of the noblest blood in the world... a Celestial Dragon! I possessed the rarest of powers. Nobility by birth! However! One day my father decided that our family of four should give up the greatest power there is and come live in this cesspool of a world! Live like a human, indeed. What a stupid, stupid man! And what do you think happened? I witnessed both heaven and hell by the age of ten. So I killed my father, the root of my suffering... and took his head to Mariejois! But the Celestial Dragons in heaven would not take back anyone from the line of traitors. There was no escape from this hell. And that's when I swore that I would destroy everything they hold dear about the world they control! The lives you've led cannot compare to what I've been through! I don't have time to waste with you miserable brats!"
