The Shocking One Piece: Marshal Chinjao

[Worlds covered so far: One Piece, Bleach, One-Punch Man, Dragon Ball...] His soul transmigrates into an 18-year-old Chinjao. From the start, he has Naruto's Eight Gates technique. He won't be a pirate: he's going to become a Navy admiral. Mock my cone-shaped head? I'll kill you! He activates the face-slapping System and spends five million Shock Points to exchange for the Zanpakuto Ryujin Jakka!

“Ding! You captured Rocks and looted his treasure, along with his Tremor-Tremor and Float-Float Devil Fruits. You're more of a pirate than the pirates, shocking the New World and earning five million Shock Points!”

“Ding! You awakened Conqueror's Haki, shocking Navy Admiral Kong, and earned 1,000 Shock Points!”

“Ding! You opened the fourth gate and used Hasshoken to instantly defeat the three-way assault by Garp, Sengoku, and Tsuru, shocking a thousand people aboard the admiral's battleship. You earned 3,500 Shock Points and successfully exchanged for a body that can eat multiple Devil Fruits without exploding!”
