He traveled to the world of One Piece and merged with the world's strongest creature to become the new Four Emperors: Kaido, the King of Beasts.

Logically speaking, this is an absolutely high-end time travel, invincible from the start!!!

But when he thought that he had come to the world of One Piece, and as the villain, he was about to face the unreasonable Child of Destiny, Master Joyboy, the user of the Nika Fruit, and the only designated savior: the Sun God.

Kaido felt as if he was invincible.

Sit-ups, version update, and martial spirit awakening!

Is he destined to follow Kaido's old path and become a stepping stone for Luffy to become the emperor?!

Fortunately, you are the child of destiny, and I am a time traveler.

If you have Nika, I can cultivate immortality.

Watch how I, the new Kaido, cultivate my immortality and defeat Nika, and restore order to the pirate world!!!

Traveled through time.

Takro looked at his reflection in the water: a spiky head, a ten-year-old body, and a dangling tail...

Got it! A true Saiyan start!

With the system in hand, the world is mine!

Becoming stronger? Super Saiyan? Bulma on the left and Chi-Chi on the right? It's just around the corner!

However...

"Haki is also qi! I've practiced correctly!"

"Although I can transform when I see a full moon, I'm not a fur tribe!"

"What is ONE PIECE? What is One Piece? Where are my Dragon Balls?!"

......

Day 1 of the journey: The Dragon Ball world is too dangerous! Stay safe and develop!

Traveling through time: Huh? It seems just like that?

After traveling through time for N years: What kind of bugs are the Celestial Dragons? This is my Earth!

[Arrived at Raftel at the beginning] [Shanks and Buggy's lifelong enemy] [Black Gun Red Hair Clown King] [Observation Kill + Tyrant + Sea Stone Bullet] [Do Not Move Fruit Ability User] [Supreme Big Pants]...

Throughout his life as a pirate, Oss's achievements are countless, but the real turning point of his fate is the desperate cry in his childhood,

"Kid, why do you have to board our ship?" The man who hid the great secret treasure at the end of the sea, the Pirate King Gol D. Roger smiled and asked Oss in front of him,

"Hahahahaha... Of course it's to turn the world upside down!"

After boarding the ship, Roger was shocked to find that he seemed to have another monster-like kid crew member, whose

strange power far exceeded that of the giants? Born with awakened observation Haki!...

[At the age of eighteen, just debuted as a pirate, you met the current overlord of the sea in the pirate world, Rocks D. Zibek. Now what you have to do is to find a way to survive in his hands. 】

Reach out your hand.

Bang!

"Captain, what are you doing!?"

The West Sea is a sea area ruled by gangs, but it also has countless powerful pirates.

Ever since Andy got the bounty point system, the guys with bounties in this sea area became his targets!

Ghost Assassin Moon, Enchantress Luna Meiyan, Bonebreaker Bruno, Flame Fist Royce, Mad Axe Tobias, these long-famous pirates in the West Sea have all been defeated by Andy!

But this is just the beginning!

Killing pirates was no longer enough for Andy, so he teamed up with the richest man in the ocean and began to offer rewards to the navy and the Celestial Dragons. Thus, the terrifying God Killer was born!

Besides killing, the protagonist also has some tenderness, is passionate, and may also do some treacherous things...

If there are any bad parts in the writing, please tell me in the comment section. I can see it in the background and make reasonable changes.

P.S.: There's no justice in this book. Regardless of whether they're pirates or navy, they're all treated as pirates. As long as there's a bounty, the protagonist will kill them all, pirates or navy alike. Anyone who provokes him will be killed! It doesn't matter if the other party is guilty or not! If you mind... forget it, mind it!

Luen journeyed through the pirate world, gaining access to the most powerful stat system, allowing him to plunder other people's stats. Looking at the golden stats on the Deserter King Coby, Luen exclaimed, "You clown, you deserve it? Take it!" Then, Luen plundered even more powerful stats. Marine Headquarters: "He is a monster capable of devouring and robbing everything, the most vicious esper in history. Without permission from the highest levels of the World Government, you must not engage him! The world's most dangerous man! 'King', Luen! Live or die! Bounty: 3.9889 billion berries!"

After inheriting Roger's legacy and Ski's Float-Float Fruit, Wayne discovered that he was terrifyingly strong.

He beat Mary Geoise and became the worst criminal in history in the eyes of the World Government!

But in addition to this, Wayne has multiple vests.

He is the founder of Candy Baby magazine, runs the World Beauty Pageant, and is the man behind all the Miss Worlds;

He is one of the Seven Warlords of the Sea. The arms company he founded single-handedly sparked the world arms race, earning him the nickname the Arms King.

Kazufu traveled to the Naruto world and became a member of the Uchiha clan.

Countless attempts to open the Mangekyō Sharingan failed, and the time had come less than a year after the night of the genocide.

In order to survive, he deduced several plans.

Defected from Konoha and joined Akatsuki.

He abandoned evil and turned to good, becoming close to Sarutobi Hiruzen.

Build a good relationship with Uchiha Itachi and establish a bond.

However, no matter which plan is chosen, the final result is a dead end.

In desperation, Hefeng complained to his ninja cat that there was no way to survive in this world.

However, he didn't expect that his own ninja cat would steal a thunder fruit for him.

Hefeng was completely confused.

But the more outrageous thing is yet to come...

Ninja Cat thinks your physical skills are too weak, so he stole the Navy's Six Styles Secret Manual overnight!

Ninja Cat thinks your mental strength is too weak, so he stole the golden bug arrows overnight!

Ninja Cat thought your swordsmanship was too weak, so he stole it overnight...

Hefeng: Lie down or push forward, this is a question worth thinking about!

This book is also called "Why Can't I, the Great Uchiha, Become Hokage?"

Traveling through the pirate world, he was swallowed by the King of the Sea at the beginning, and then awakened the god-level [Cube Fruit]!

Everything in the world can be decomposed and reassembled! Others work hard to develop fruits, I directly read the data and synthesize it with one click!

While the navy was still showing off their pacifism, my 100-meter Diamond Gundam had already been assembled.

Everyone thought I was adventuring on the Grand Line...

They don’t know that every time I arrive at an island, I copy the data of the entire island!

The Battle of Marineford breaks out, and the eyes of the world are focused on the execution platform...

I printed a "Sky Island" directly above the Navy Headquarters! ?
