I used to have a cushy Marine job, thanks to my grandfather-grandson relationship with Garp, I could have easily coasted like Kizaru, punching in and out while working a desk job as a low-ranking clerk. But everything changed when I took Garp to that island and ate that fruit. Where did this ridiculous rumor even come from? What's this about me being the illegitimate child of two Emperors, Kaido and Big Mom? PS : A single pairing with Uta and mc will supposedly act as a 'spy' later in luffy ship.

Karl inexplicably transmigrated into the Marvel Universe… This was a world perpetually on the brink of catastrophe. You could be asleep in your apartment when the Hulk rampaged through a city block, reducing concrete and steel to rubble and turning ordinary civilians into collateral damage overnight. Beyond Earth’s borders, alien empires and interdimensional entities constantly set their sights on the planet. From extraterrestrial warlords to reality-warping demons lurking in other planes, invasion or annihilation was never a distant possibility—it was a recurring event.

While many sought peaceful coexistence, extremist factions such as the Brotherhood of Evil Mutants had repeatedly embraced violence and terrorism in pursuit of mutant supremacy. Meanwhile, super-villains with ambitions ranging from domination to total destruction emerged in endless succession. Even S.H.I.E.L.D., the intelligence agency tasked with safeguarding global security, had been deeply compromised in the past by Hydra—a clandestine terrorist network that infiltrated its ranks for decades, manipulating world events from the shadows. After inheriting the original owner’s memories, Karl’s first instinct was to rely on his Chinese nationality and relocate to China, hoping distance might offer a measure of safety.

A world where gods walk among men. People can flatten mountains with their fists, cut in half entire galleons with a single sword, and control mystical abilities that completely tear apart the laws of physics, in the form of tiny fruits that just anyone can eat. In a world like that, what can one even do? Well, when you have the power to cheat, you can do pretty much anything.

Jin was just another model ship hobbyist—until a cosmic glitch dropped him into the world of One Piece... along with his prized aircraft carrier. Within hours, he’d already made a fatal mistake: killing King Wapol. Then things got worse. When his model carrier swallowed the king’s Munch-Munch Fruit, it didn’t just transform—it awoke. A sentient, evolving Demon Carrier, driven by a single, monstrous instinct: to consume other Devil Fruits. It devoured the Mushroom-Mushroom Fruit—and turned itself into a living factory. It devoured the More-More Fruit—and wiped out a Buster Call in one shot. It devoured the Flare-Flare Fruit—and its burning deck became an inferno that melted entire islands. Now, across the Grand Line, a new warning echoes through the ranks of the Marines: Threat Level—UNKNOWN. Target is not human. Target is a nation on wings. DO NOT ENGAGE.
