One Piece: Cutting Down Ace with One Slash at the Start

Accidentally reincarnated into the world of One Piece, he becomes one of the four brats under Garp's care. After fourteen years of mooching booze, he activates the Strongest Template System and unlocks his base template: Kenpachi Zaraki, the King of Basic Attacks. Scissor Seven, White, Sasaki Jiro, Killer B, Himura the Manslayer... A string of templates fuse together, giving rise to the ultimate battle maniac-the King of Basic Attacks. Ace: "I'm Ace, and I really wasn't cut down with a single slash. I swear on my name as Whitebeard's adopted son." Zoro: "I hear the Gotei 13 are all powerful swordsmen. I, Roronoa Zoro, will definitely become the strongest." Hawk-Eye: "My blade has never broken, but from this day forward, I'm putting it away for good." Kaido: "I'm the strongest creature on land, sea, and air. These bandages wrapped around me are only here because I'm too cold..." Blackbeard: "His blade isn't heavy at all. It's just that after its force was doubled, my legs went a little numb and I couldn't walk." This world was never peaceful to begin with. When Bai Yu unlocks his base template to one hundred percent and fuses all those characters together, he will trample this world to pieces. "There is nothing in this world my blade cannot cut."
