Donquixote Rosinante (Corazon)

Who is he? Donquixote Rosinante, better known as Corazon, was the younger brother of Doflamingo and served as a high-ranking member of the Donquixote family. But while his brother became a cruel tyrant, Corazon chose a completely different path: He secretly worked as a spy for the Marines to end the crimes of his own brother.
Corazon was born into a family of Celestial Dragons, but his life took a dark turn when his father decided to give up that status and live among ordinary people. The consequence was devastating, as the family was tortured by the angry citizens. His mother died, and Corazon had to watch as Doflamingo slowly became a monster.
Why is his fate so sad? When Corazon met the young Trafalgar Law, who later became a strong ally of Luffy, he was determined to save him. Although Law was doomed to die due to his illness (the “White Lead Syndrome”), Corazon took him under his wing and desperately searched for a cure.
Ultimately, he managed to steal the Op-Op Fruit – Law finally had a chance to survive. But Doflamingo discovered his betrayal. In one of the most tragic moments of the series, Corazon was coldly shot by his own brother. With his last strength, he used his Silence Fruit to protect Law so that he could escape unnoticed.
