Sabo

Sabo is the sworn brother of Monkey D. Luffy and the late Portgas D. Ace, and the Chief of Staff of the Revolutionary Army — the organization's No. 2, second only to Dragon. Believed dead after a World Noble shot his fishing boat as a child, Sabo survived but lost all memories of his past until the news of Ace's death at Marineford triggered their return. He inherited Ace's Mera Mera no Mi at Dressrosa and has since become one of the most wanted men in the world, framed for the attempted assassination of King Cobra of Alabasta at the Reverie.
