Human-Human Fruit, Model: Shapeshifter, Merge with the Merry

No sucking up to the protagonist, and no System!

The real world of pirates is completely different from the manga. Everyone has two sides to their nature.

..

Who was the biggest winner of the Summit War?

Buggy the Star Clown? Blackbeard?

Neither. It was Zhou Yangfan, who devoured Whitebeard's ship, the Moby Dick, turned its mast into a scabbard, and sheathed the Murakumogiri inside it.

..

Devour and fuse with Devil Fruit abilities.

Absorb metal to increase strength, absorb wood to boost stamina. Absorb special ship equipment to gain special abilities.

Install a steam engine to gain the Steam Explosion Fruit skill.

Install an air-current radar to gain the Airflow Sense Fruit skill.

..

Modify the interior of the ship.

Merge the infirmary with kidneys and a liver to improve the recovery of the wounded and reduce the chance of fatal injuries.

A super-kitchen, a pressurized physical training room, a research lab for the two colors of Haki...

And this is all before the Human-Human Fruit, Model: Shapeshifter, has awakened.
