Dragon Ball: Saiyan Destroyer

Demon Slayer -> JJK In the demon-infested world of Demon Slayer, an ordinary college student, Rin, transmigrates, awakening the [Dimensional Template System]. His first draw? The overpowered [Uchiha Sasuke - Mangekyo Sharingan] template—granting him Lightning Release, Chidori, Amaterasu, Susanoo, and unmatched combat instincts, all without losing his own personality or looks. Armed with a modified Kusanagi sword that slays demons like a nichirin blade, Rin refuses to watch the canon tragedies unfold. Kyojuro Rengoku will live to see another dawn. Shinobu Kocho will smile under blooming wisteria, not fade into poison and regret. Every heartbreaking fate is about to be rewritten by sheer, unstoppable power. From casually one-shotting the Hand Demon to facing Muzan, Rin stands as a purple giant of destruction, Sharingan blazing. "Muzan, what do you take life for?" Fire Release: Susanoo Kagutsuchi! A ruthless yet chill transmigrator shatters the Demon King's world—because this time, the regrets end here. OP MC, system progression, canon fixes, and epic cross-power clashes

In a world where summoners wield the power to call forth vampires, elves, angels, demons, and all humanoid creatures from across the realms, Nathan found himself unable to summon beings except from beasts.  However, those beasts are not ordinary beasts. They are divine beings who once stood at the same level, if not higher, than the legendary creatures the world ever knew.  Casting his gaze to the left, Nathan sees numerous summoners accompanied by the likes of demon kings, archangels, vampire progenitors, and other legendary beings. Turning to the right, a massive army of alien symbiotes is waiting to attack.  There was no fear in his eyes, because standing on his left is a majestic wolf who managed to kill a god, the legendary eight-headed serpent coils on his right, above him is the bird who is glowing like the sun, and behind him is a dragon that once gnawed the roots of the world tree.  “Let the war begin.”

[Harry Potter Fanfiction + Mastermind Genre + Strategic Scheming] [Early stages focus on survival and growth; a slow burn] [Ambition and the desire for conquest hidden behind a trustworthy smile and seemingly sincere words] Tver, the most brilliant graduate in Durmstrang’s history, has arrived at Hogwarts. “One day, Muggles will use science to observe magic, expose our secrets, and build mathematical models for every spell. When that day comes, what will wizards do?” “Be locked away like rare beasts in cages?” “Or…”

They won. The heroes defeated the forces of darkness, and the world entered an age of peace. Crime is rare. Monsters are contained. People live safely, predictably, happily. And for everyone else, that’s perfect. For Oriana, an immortal Forest Fae, it’s unbearable. Where others see peace, she sees stagnation. A world repeating the same safe day, over and over again. Nothing changes. Nothing grows. Nothing *moves*. If the world no longer has a villain to shake it awake…then she’ll become one. Not with death and destruction — she’s not a psychopath — but with clever chaos, illusion, and disruption. From replacing fruit with convincing-looking mud, to unravelling guilds, nobles, peacekeepers, and eventually even the celebrated heroes themselves, Oriana sets out to bring surprise, tension, and momentum back into a world that’s grown far too comfortable. After all, a world that never changes…is already dying.

It's a Fanfic of Gundam Ibo where Mc is the twin brother of Mikazuki Augus. . . . . . . . . . . . . . . . . Check it out. I am way to lazy to write a Sypnosis.

Bunshichi, a morally questionable 28-year-old playboy who dies and reincarnates as baby Goku while retaining his adult memories and consciousness. With no prior knowledge of Dragon Ball, he must navigate growing up as the legendary Saiyan hero while his adult cunning and street smarts clash with Goku's traditionally pure nature.

Ivan was a Seattle programmer until he woke up in Middle-earth wearing the face of Prince Legolas. He wields "Universal Magic Compatibility," a soul-trait allowing him to absorb Elven resonance and Dwarvish craft-song simply by witnessing them. As the Fellowship departs, he uses his meta-knowledge to intercept the Uruk-hai, desperate to prevent the breaking of the group. Deep in the forest, he realizes his presence is a "blank slate" that can either save the world or lead it into a corruption the Valar never foresaw.

She was reborn into the highest bloodline in the world, a Celestial Dragon of the Holy Land. Yet she could not see. To the nobles of Mary Geoise, she was a flaw. To the World Government, she was expendable. But within her lived two souls. One calm as still water. One merciless as a storm. Denied sight, she sharpened her hearing. Denied freedom, she sharpened her will. Denied respect, she sharpened her blade. From the shadows of the Holy Land to the battlefield of Emperors, her sword will redraw the balance of power. The era of pirates will tremble. Because a blind Sword Empress has awakened.

Before you stands the Reborn Laughing Storm, the Legendary Dragonrider, the Supreme Pyromancer, the Superb Water Wizard, the Charismatic Wild Stag, the Breaker of Chains, the Destroyer of the Long Night, the Collector of Dragons, Wolves, and Roses, and the One True Sun across the Narrow Sea. What’s that? Too many titles to keep track of? This is Gendry—the story of a blacksmith’s rise to greatness. This is a fan translation of 权游：雄鹿的风暴 by 稚嫩的刀笔吏.
