One Piece: Big Mom's Eldest Son, Born with Three Hearts

Transported into the world of One Piece, Rector becomes the eldest son of Charlotte Linlin!

From the start, he binds to the 'Divine Aberration Physique,' gaining three hearts and the ability to perfectly fuse three Devil Fruits! He also awakens the 'Eye of Omniscience,' allowing him to hear the thoughts of all things and see the paths of the future!

It is the age of Rocks, and the battle of God Valley is imminent. Looking at his younger siblings crying for food beside him, Rector decides to lead his family in defying fate!

Nobody would even feed the Mochi-Mochi Fruit to a dog? He directly snatches the Fish-Fish Fruit, Mythical Zoan: Azure Dragon Form, then casually tosses it to Katakuri. "If you're going to be one, be an emperor who transforms into a dragon!"

He steals the Magnet-Magnet Fruit to forge Cracker into a Magneto; he merges flesh, blood, and the frailty of the body to create the mechanically ascended android girl, Smoothie...

Years later, the Paramount War erupts.

Beholding the world-destroying Azure Dragon circling the heavens, Magneto commanding a tide of steel, and Rector seated upon the throne with three god-tier fruits-the Rumble-Rumble Fruit, the Float-Float Fruit, and the Vampire Fruit...

Sengoku and the Five Elders completely collapse. "How is this a pirate crew? This is clearly a mythological family!"
