Jin got isekai'd into the One Piece world with a model aircraft carrier-and immediately screwed up by accidentally killing King Wapol. But when his model ship devours the dead king's Munch-Munch Fruit, an abomination is born: A living Demon Carrier that hungers for the power of other Devil Fruits. It ate the Mushroom-Mushroom Fruit and became a self-sustaining factory... It ate the More-More Fruit, and its cannons obliterated a Buster Call with a single shot... It ate the Flare-Flare Fruit, and its deck became a sea of fire hot enough to melt islands... Marine Headquarters Alert: "Threat Level-UNKNOWN. Target is not a man, but a mobile, sovereign nation. Do not engage. Repeat: DO NOT ENGAGE!!"

Transmigration brought me into the world of One Piece-but as a mere Earthling with a pitifully low racial stat cap, I was nothing more than a combat-inept weakling. To make things worse, I was exiled to the infamous Marine Branch 157, known far and wide as the Navy's retirement home. And yet... A few years later, what was once a crumbling outpost with only a handful of half-hearted marines- ...has transformed into a sprawling, modernized city that stuns the world.

Part - 1 of this fanfic https://www.wattpad.com/story/400836366-naruto-teaching-makes-me-stronger Mugetsu transmigrates into the world of Naruto as an ordinary Chūnin instructor in Konoha-while secretly serving under Danzō's Root Organization. Knowing that weakness means death, he resolves to change his fate. When the Teacher System awakens, Mugetsu gains power through his students' growth. [First A-Rated Teaching Evaluation Complete - Reward: Mastery in Fire Release Chakra Nature Transformation.] [Student Shisui gained +30 Chakra. You gained +60 Chakra.] From mentoring Shisui, Kakashi, Obito, Guy, and Rin, to researching Sealing Techniques and Breathing Styles, Mugetsu quietly shapes Konoha's future geniuses while growing into a legend himself. But as the Third Great Ninja War approaches and Root's shadow closes in, Mugetsu must decide-will he remain a pawn of Danzō, or rise as the teacher who forges the next generation of heroes?

(Sub: Ninja Scientist: Defeating Gods with Aerodynamics and Dust Explosions) "Don't hold us back, Tetsu," Fugaku Uchiha said, his Sharingan spinning with cold pity. "In this world, bloodlines are everything. A civilian like you should stay in the lab." I didn't argue. I just pushed up my glasses, calculated the precise air density, and flicked a handful of ordinary flour into the air. "In science, Fugaku, there are no miracles-only reactions." Ten seconds later, the invincible Uchiha fire-style met a massive Dust Explosion. As the smoke cleared, the genius finally understood: his eyes could track my movements, but they couldn't see the laws of physics. Transmigrated as Nishikawa Tetsu, a modern researcher in the brutal era of the Second Shinobi War, I have no bloodline and no system. All I have is a PhD-level understanding of the universe. While others waste chakra on flashy hand signs, I'm calculating muzzle velocity and fluid dynamics. From teaching Minato the aerodynamics behind the Rasengan to outfitting Konoha with weapons that make Susanoo look like a toy, I'm here to prove one thing: A railgun at Mach 7 doesn't care about your destiny. What to Expect: [Physics Over Bloodlines]: Dismantling S-rank Ninjutsu using high-school chemistry and advanced logic. [The Genius's Teacher]: Watch Minato and Fugaku go from "protecting the weakling" to asking for homework help. [Absolute Fix-It]: No Uchiha Massacre. No Minato's sacrifice. A high-burn, tactical survival story where science wins. [Smart MC]: No shouting for power-ups. Every victory is a calculated, brutal masterpiece of research.

Thrown away by the Zenin clan before he ever had a chance to matter, Ren awakens a system of eight impossible arts that lets him devour curses, forge weapons, command spirits, and break every chain. Satoru Gojo was meant to stand at the top. Sukuna was meant to be the nightmare at the end. Ren Zenin was never meant to exist. Now the timeline is breaking in this Jujutsu Kaisen AU.

I died and woke up in the shinobi world. An incompetent organization told me there was a way back, but there was one condition. I had to die again. Only then could I claim my transmigration reward and go home rich. Survival was never the goal. All I had to do was find the right opportunity, make it look heroic, and let the world handle the rest. But there was one problem. No matter how reckless I became, the universe refused to let me die.

'Just how long have you been messing around in the Shinobi world? I've been here since the Sage of Six Paths founded Ninshu!' I was there for the battle against Kaguya. I was still there during the clash between Indra and Asura... I have witnessed the rise and fall of eras, sitting idly by as the Shinobi world wages its endless wars. Though I rarely lift a finger, legends of my existence are etched into every corner of this world. Time is a ruthless blade that strikes down even the brightest of prodigies, but I intend to stand taller than time itself. I am the one who knows all there is to know in the Shinobi world-a true Immortal! .............................. "Let's take a look at your 'Shinobi Age'." "Oh? You've already reached a century old? My, you gave me quite a fright!" "Let me give you a baseline number, just so you can grasp the sheer caliber of the veteran standing before you..." "My age in the Shinobi World is.... 5,000 YEARS!!!"

Yuu transmigrates into the Naruto world at the worst possible time: the eve of the Third Shinobi World War. Before he can even adjust, he awakens a Reincarnation Panel that allows him to reincarnate into different eras of the ninja world, live through them, and return with what he has earned. These are not dreams. They are full lives. He once descended into ancient history and built a golden age as the Daimyo of the Land of Ancestors, standing at the beginning of chakra's legacy and becoming the father of the Sage of Six Paths. He later walked into the blood soaked Warring States Period, contending with Hashirama Senju and Madara Uchiha, guiding the Uchiha to the height of their power. And when the era demanded it, he took everything, including Konoha itself, and became Hokage by force and by will. Every reincarnation reveals another hidden layer of the world. Every era leaves another mark on his soul. Now, in the present, as the Third Shinobi World War approaches, Minamikawa Yuu is no longer a single man. He is the sum of countless legends. And all of it begins with his first throne: Daimyoof the Land of Ancestors.
