When Kaido merged with the soul of an unlucky transmigrator, he learned that the world he was in was a manga, and that he was merely a stepping stone for Luffy, the so-called chosen one of destiny, to defeat him.

"What kind of bullshit is Wang Luffy, Chosen One, Joy Boy? I'm going to smash you all to pieces..."

'Ding, system loading...'

Kaido: "So this is the cheat code of that unfortunate transmigrator? It seems that after merging with that guy's memories, I not only know the direction of the plot, but I also have a cheat code to use..."

'Ding, system loading complete. You are not the host of this system. The system will automatically unbind you. Goodbye...'

Kaido: "Damn it..."

(Cheerful, cold-blooded, ruthless, bloodthirsty, ambitious. Kaido is the Kaido from the original work, but one who knows the plot; his personality won't change much.) (Completed novel: "One Piece, Me, Marco, Starting with the Marineford War")

Want to know what it's like for the Blood Emperor to not go bald? Then come and see for yourself. A work by the Rebellious King.

[Navy] + [Slightly Abusive Protagonist] + [Justice] + [Transformation Novel]

The girl, who had endured many hardships, became a member of the navy, and sang her own song of justice.

Smoker: As a student of Professor Zeff in the same year, I am ashamed of myself. Am I the mad dog or is she the mad dog?

Akainu: I greatly admire Erza's sense of justice. All evil pirates should be eliminated!

Sengoku Marshal: Erza, can't you obey orders? Sometimes this world isn't just about passion; there's also human relationships involved. Hey, don't give me that pitiful look as if I'm bullying you.

Hawkeye: I never imagined a girl could reach this level in swordsmanship. Erza, you are a worthy opponent.

Wang Luffy: Everyone run! If the opponent is Erza, we'll really be killed!

Erza: My justice is the sword in my hand. Pirates, you can't escape! Hahahaha!

What kind of storm will a powerful navy that hates pirates to the point of madness stir up in this world?

The protagonist is relatively weak in the early stages, but very brave, so he is often beaten up. There is no system, so he may be almost killed many times. The protagonist has two personalities: combat and social. If you don't like this, please do not read.

Good news! I traveled through time! They named me Shinji!

Bad news! I've traveled through time again!

Good news! It seems like it's modern times! I can finally go back to playing games and ordering takeout!

Bad news! I was born in a country where life is pretty good! I heard that Antarctica is melting! This doesn't sound good!

Good news! I—the lifelong friend of the legendary Azeroth Paladin Marcus, the Light of Dawn, Holy Highlord of the Knights of the Holy Light, the Uncrowned King, Grand Mage of Tirisfal, High Priest of the Voidlight Temple, Archbishop of Light and Shadow, Titan Slayer, Maw Walker, Guardian of the Laws of the Universe, Conqueror of the Void (all perish together)—a disciple of the Imperial God of Cangjian Villa. I'm Ye Han, also known by my courtesy name Hehua, and English name John. You can also call me Jehovah—fearless!

Su Ming transmigrated, and luckily he encountered the god in charge of transmigration, but unfortunately this god was not very reliable.

What happened to the promised Gundam 00 world? What happened to the promised recommendation to Celestial Being? What happened to me piloting a Gundam?

In this life, Su Ming is a mecha pilot in a chaotic world who unexpectedly obtains a Haro with a Gundam 00 system!

And this Harrow actually has multiple different personalities.

It would sometimes call itself Tieria Erd;

He then introduced himself as Lockon Stratos;

And there are actually five such personalities!

What would it be like to be powered by a GN Drive-driven Strike Freedom, Nu Gundam, or Wolf King?

Having witnessed the horrors of a chaotic world, Su Ming chose to rebuild the Celestial Being organization starting in Anaheim, vowing to eradicate all conflict in the world.

He declared to the world: "I am Gundam!"

During this process, Su Ming discovered that this world was not so simple. Countless pieces of evidence showed that this world was highly similar to the Gundam 00 world, and more secrets awaited his exploration.

P.S.: This story is set in the Gundam 00 universe and features original mecha. Newcomers who haven't read Gundam can read it without difficulty and can treat it as a mecha novel. Images of the mecha can be found in the comments or book circles.

Reborn as the adopted son of Orb's leader, Yuni Athha, with his foresight into the future and the "Gundam Technology System," vows to reverse the tragic fate of Orb and his childhood sweetheart Flay.

With the otherworldly black technology granted by the system, he built his own Gundam "Dawn" using the GN Drive as its core, and brazenly intervened in history starting from Heliopolis. Saving Frey's father was only the first step in changing his destiny.

In the crucible of war, Frey also sheds her naivety and grows into a top commander and tactical core (BSC) who can synchronize with Yuni's soul. The two join hands, combining the strengths of a hundred technologies, and finally create the ultimate mobile suit equipped with a dual-furnace system and GN Bit - "Destiny Gundam".

When Kruze arrives in the Oracle Gundam, carrying the will to destroy, Orb faces its final battle. Yuni and Frey will pilot the "Destiny," using their mortal bodies to slay gods and usher in a new dawn for the world with steel and willpower.

This is a Gundam SEED fanfiction that blends technological elements, a single female protagonist's deep affection, and intense mecha battles. Watch as the protagonist uses technology to crush fate and protect her beloved and her country!

Book description: "Mr. Lin Feng, there are rumors that you control the Azure Lane and the Crimson Axis, and even bring many faction flagships under your command. Is this true?" Lin Feng: "Of course it's false. This is a slander against me!" "So..." Lin Feng: "Actually, there are also Siren." "???"

Lin Ling traveled to the world of Girls' Frontline and became the forgotten Commander Zero. Without cheat codes, luck becomes the cheat code; without cheat codes, then he becomes the cheat code himself! Other travelers want to reach the pinnacle of life, but he just wants to go home.

(Original title: A pioneer trying to be a hero)

What? Using the Pioneer PF game template to fight in other worlds? Is there such a good thing?

Oh, it looks like a live game broadcast, and the audience are gods?

Then I should be more popular if I play a hero.

Please reward me and pay attention to me.

That's right, I was just pretending to be a hero in order to gain more benefits. I'm just a hypocrite and can't be a hero. It's impossible.
