He transmigrated and became the nephew of Gol D. Roger, the Pirate King.

He recruits the sniper King, eats the Ancient Zoan Original Bird Fruit, and becomes a sky-bound sniper. He wields a rifle that has eaten the Mythical Zoan Black Tortoise Fruit, and wears a belt infused with the Bomb-Bomb Fruit.
