Portgas D. Ace : Soverign of Flame

After reincarnating into the world of One Piece, a modern-day soul finds himself reborn as Portgas D. Ace, the adopted brother of Monkey D. Luffy and son of the Pirate King, Gol D. Roger. But this isn’t the same Ace doomed to fall at Marineford—this Ace has memories of a past life, scientific knowledge, and a burning ambition to surpass every limit. Determined to change fate and rise above the constraints of the Mera Mera no Mi (Flame-Flame Fruit), Ace embarks on a path of relentless self-improvement. As he trains his elemental flames to new extremes, develops never-before-seen fire-based techniques, and challenges the very nature of Devil Fruit powers, Ace seeks to become something more than just a pirate. With the specter of Akainu and the World Government looming on the horizon, Ace forges new weapons of flame, discovers hidden potential within his fruit, and sets out to become not just a commander—but a Fire Emperor. In a world where strength defines destiny, can a reborn Ace ignite a revolution and blaze a new legend across the seas?
