One Piece: I Am the Heroic Titch

On the day of Roger’s execution in the Sea Circle Calendar year 1498, Teach was reborn on the eve of reaching the top.

In his previous life, he gathered the Dark-Dark Fruit and the Tremor-Tremor Fruit and rose to become one of the Four Emperors. But his body could not withstand the backlash of wielding two Devil Fruits. His flesh withered and decayed, his strength plummeted, and he ultimately died trapped on Hachinosu, all his ambitions in vain.

Returning with the lessons of his past, Teach no longer fixates on powerful fruits. He first heads to Drum Island, kills Wapol, and takes the Munch-Munch Fruit.

He spends two months in seclusion, consuming metal to temper his body, shedding his bulk and forging a lean, powerful two-meter frame. His entire bearing transforms.

After that, the Dark-Dark Fruit, the Tremor-Tremor Fruit, the Azure Dragon Fruit, and other top-tier Devil Fruits all fall into his hands.
