crossover

Not Harry, in the Harry Potter world who is quite frankly about to get f****d by the anomalies in the world.

After dying from overwork, a young man is reborn in Teyvat… as Jean Gunnhildr, the Acting Grand Master of Mondstadt. Burdened with duty, secrets, and a mysterious entity known only as “D,” she discovers that her new life isn’t just about protecting Mondstadt—it’s part of a larger game spanning multiple worlds. Reincarnators, hidden systems, and forces beyond even the Archons begin to move. This time, Jean won’t just endure the workload. She’ll control the game.

Orion, a college student who was unexpectedly sent to another world by Truck-kun, discovered that he wasn't reincarnated as a humanoid creature, but as a giant ORT monster! But it didn't matter. He knew that ORT possessed all sorts of strange abilities, and mimicking humans, naturally, wasn't a problem. However, the most urgent task was to discover what kind of universe he was in. Does Iron Man exist? Or a Batman? Or perhaps in some Xianxia world? Huh? Wait a minute, what the heck is "Extreme Evil Rider"? And what do you mean by telling me to find your apprentice? What on earth is this travel assistance system I have in my head? If I'm the one traveling, who is that blonde beauty shaking my hand? A player who had almost forgotten the story of Genshin Impact calmly accompanied Luminus and Skirk on their journey through the Seven Nations, possessing enough power to destroy a star. Why do you need to travel when you can already destroy and forge stars? If I don't supervise this golden retriever's journey, who will compensate me for the system rewards I miss and the encounters with beautiful girls all over this world? ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Warning: The power levels are way out of whack; Surtalogi is way too powerful: he's been at the peak of his power for hundreds of chapters.

Warning, the first 5 chapters were very info heavy. They had info for how the overall world/power structure will work. That info is now in the auxiliary chapter. The story proper starts on chapter 6. Rule #1: When a Random Omnipotent Being offers you a custom character sheet and a cross-dimensional fast pass, read the fine print. Rule #2: There is no fine print. Only chaos. Blessed, balance-tested, cartoon-fueled chaos. Welcome to the prototype run of The Game. You weren’t meant to be a player. You didn’t get a tutorial. And yet here you are armed with a half-finished system, a backlog of suppressed media knowledge, and a growing suspicion that the GM is just making it up as they go. (Spoiler: they are.) This isn’t just a story. It’s a template. A Save/Load checkpoint. A cosmic draft folder. It’s where R.O.B. 37 the most dangerously curious of the Random Omnipotent Beings starts testing out what happens when a wish-fulfillment engine gets smart. And bored. And possibly a little nostalgic. Worlds will be revisited. Tropes will be broken. AUs will be built, explored, then immediately patched. Nothing is sacred. Everything is permitted. (Except for linear plot structure. That died on page one.) --- Disclaimer: Only the main character and the occasional OC are original. The rest? All properties belong to their respective creators. This is fanfiction with a capital F, and fanfiction with a capital F is legally obligated to go completely off the rails by arc three. You’ve been warned. --- Why limit yourself? If "nothing is true, and everything is permitted", is true then why limit yourself? The first few chapters are the template I'm putting in place for Random. Omnipotent. Being. (R.O.B.) 37. He is a true craftsman of wish fulfillment and balanced chaos. From a young age he studied the toons. As he grew his entrance to the litany of written works started early. By the time he finished formal schooling (k-12) he was aware of more media than he could ever truly finish in his life. So many worlds, so many stories. By the time he had reached his early 30's his eyes had seen so many takes on familiar stories and had written on so many posts It's an AU, that he decided to make his own Alternate Universe(s).....

Uchiha Kaoru!!! After transmigrating into a member of the Uchiha clan, I discovered that my Sharingan could use skills from League of Legends. For medical ninjutsu, I have Soraka's skills! For genjutsu, I have Shaco's fear! For taijutsu, I have Lee Sin's "Iku"! Ninjutsu is even easier; with over a hundred heroes, I will have over a hundred kinds of hero-based ninjutsu!

My Anime Crossover Life Is Completely Broken! Satoru Mikami thought he knew what a normal life was. Then he woke up in a completely unfamiliar world. At first, he assumed he had simply been transported to another universe. But after encountering supernatural beings, sorcerers, vampires, devils, and characters who definitely shouldn't exist in the same world, Satoru realized the truth— This world is an Anime Crossover! And as if that wasn't strange enough, Satoru has awakened with a mysterious Trait System. Unlike ordinary systems that simply grant skills or rewards, his Trait System allows him to acquire, evolve, and combine extraordinary traits—giving him the potential to overcome almost any obstacle standing in his way. Sounds great, right? There is only one problem. Something is seriously wrong with this world. Why is Yuji Itadori suddenly a girl? Why is Kiba Yuuto... Yuki Kiba?! Satomi Gojo. The gender-bent version of the strongest sorcerer. Satoru's reaction? "...Yeah. That waifu is mine." And why are so many familiar characters completely different from the versions Satoru remembers? As Satoru explores this bizarre world, he gradually discovers that the boundaries between different anime universes have completely collapsed. From the vampires and supernatural battles of Strike the Blood, to the devils and fallen angels of High School DxD, the cursed energy of Jujutsu Kaisen, and the chaotic romantic comedy of Saekano: How to Raise a Boring Girlfriend— they have all become part of the same world. With a broken Trait System, countless supernatural factions, gender-bent characters, and multiple worlds colliding into one ridiculous timeline, Satoru's new life is destined to become anything but ordinary. The crossover has begun. And Satoru intends to become strong enough to stand at the very top of it. Note — This is Not a Translation This is An Original Fanfiction with A similar plot To a Chinese Poison Dead Braincells Fanfiction. Worlds Currently Known: - Strike the Blood - High School DxD - Jujutsu Kaisen - Saekano — How to Raise a Boring Girlfriend - The Testament of Sister New Devil And more worlds will continue to join the crossover...

In the universe of Honkai: Star Rail, geniuses shape the fate of worlds. Lin Yi… is not one of them. Yet somehow, after transmigrating into the cosmos, he receives an invitation from Nous and becomes a member of the legendary Genius Society—a gathering of minds capable of rewriting the laws of the universe. There’s only one problem. Lin Yi is a fake genius. Surrounded by monsters of intellect, he can only survive by proposing increasingly outrageous ideas: Imprison Abundance abominations in a pocket dimension and launch them as cosmic weapons. Turn the Propagation Swarm into an infinite biological supercomputer. Create a moral “Sword of Damocles” to force the followers of Abundance into family planning. Every plan sounds insane. And somehow… they work. As his chaotic ideas begin reshaping the cosmos, Lin Yi slowly realizes a terrifying truth: The universe may be saved by geniuses— —but the disasters threatening it might have started with him. The story only really enters its full chaotic ‘scheming genius’ mode after around a hundred chapters, and the trouble-making genius group continues to grow larger and larger.

( Vol. 001 ) The Red Emperor & The Demon King of Sixth Heaven ( High School DxD/Fate ) Falling into a magic circle is one thing. Meeting a scary gun lady inside of it? That was scary. But turning into her, succeeding her, and inheriting her legend? Yeah, that was the icing on the cake. Namikaze Haru was perfectly fine with that, though, and if anything, the gender change was secondary. (Or so she learned.) ( Vol. 002 ) The Red Emperor & The Great King of Destruction ( High School DxD/Fate ) Namikaze Haru found himself involved in a figurative "holy war". A grail that can grant omnipotent wishes? Fast way to become a Harem King! ... if he can survive the other enemy Masters first. Hey, at least he's got a smoking hot Servant with him! ( Vol. 003 ) The Red Emperor & The Fox Priestess of Peerless Beauty ( High School DxD/Fate ) Namikaze Haru was always normal. And a pervert. The odds of him ever finding a girl were slim. So when Yuuma Amano approached him, there were no words that could describe the happy feeling in his heart. And then she attempted to kill him, revealing her true nature. At that moment, however, Haru's desperate pleas for someone to save him woke something inside of him. A secret that he was not aware of. Something that a certain vampiric troll is watching with great enthusiasm. ( Vol. 004 ) Flutter of the White Emperor ( High School DxD ) Ambition is a flame that is to be handled with utmost care. Ambition can, will, and has scorched the very world we claim to love. The fuel of ambition, more often than not, is power. What happens when the White Dragon Emperor has power and ambition in abundance? Well, the end of everything. With few he can trust and no knowledge of his future, things will be bleak without change. ( Vol. 005 ) Levia-tan's☆Harem King ( High School DxD ) Uzumaki Ruto used to be a normal, healthy teenager. His life was good. He was smart, strong, and very popular with the ladies. He knew his life was supposed to be simple. He was supposed to live normal lives, get a normal education, perhaps someday give up the foolish notion of building his own harem and settle down with a nice girl. It would have been nice... It could have gone on forever. Then some S&M-wearing Fallen Angel shit came around and messed everything up. A retelling of High School DxD with the focus on my OCs Haru and Ruto replacing Issei and Vali. ( Vol. 006 ) The Delinquent Queen & The Oppai Dragon ( High School DxD/ God of Highschool ) Naru is reborn into the universe of Highschool DXD with a Sacred Gear that belongs to another universe? And... did I mention that her Sacred Gear is too OP? AU-OP/OC-SI/OC-Reincarnation-High School DxD and The God of Highschool Crossover. ( Vol. 007 ) Love, Friendship, and Heart of Cards! ( Yu GI Oh! ) 16 year old Naru Scarlet finds herself in Yugioh season 0 after being electrocuted. She wakes behind a school and immediately bumps into Yugi. It’s a dream come true for her. Though she soon finds herself scared for her new friends. And why is she the one being rescued instead of Tea? Why do they all have American names and not Japanese? Is it the Manga or Anime? What’s happening! ( Vol. 008 ) Love, Friendship, and Heart of Cards! II ( Yu GI Oh! GX ) After 10 years after the match between the King of Games and Atem, Domino City opens the Stadium doors, to give new students a spot to join the prestigious school of Duel Academy island. Ruto and Haru are contestants with dreams to achieve by passing the exam. What does a new Generation do to an Island full of adventures? A retelling of Yu-Gi-Oh! GX with the focus on my OCs Ruto and Haru replacing Jaden and Syrus. ( Vol. 009 ) Beloved Daughter of Konoha ( Naruto ) Kakashi fell to his knees, trying his hardest to stem the flow of tears from his eyes and clutching a hand to his chest, trying his hardest to stop the ache coming from his heart. Neither was successful. "Best. Team. Ever." He declared, weeping tears of j

In his freshman year, Max-weeb and two-time Otaku League champion-got exactly what he wished for: Truck-kun sent him straight into the DanMachi universe. The catch? He's in a Devil's body. The world? Filled with monsters, blessed adventurers, the legendary OEBD, and gods desperate for entertainment. Surviving seemed hard enough-until a goddess decided he was worth her personal attention. Shit!

Transmigrated into Funina... From then on, a strange sect appeared on the Douluo Continent. Other sects relied on fighting and killing to establish themselves. The Water God Sect started with a cake. Three martial souls that looked like they had escaped from a drama troupe. Plus an ultimate weapon that was always asleep. Spreading the faith mainly relies on: "Are you hungry? I have some cake here." "Can't awaken? Come and try it. If it doesn't work, you don't have to pay... oh, it's free to pay anyway."

By the will of the gods, or perhaps their mistake, Zorn was thrown into the world of Fairy Tail. Blessed with the power of light itself, he awakened the abilities of the Pirate Admiral Kizaru, absolute speed, overwhelming attacks, and an untouchable body of light. On top of that, Zorn mastered Holy Light Magic, a sacred force feared by demons and dark mages alike. Rising at an unbelievable pace, he became the youngest S Class wizard in history and soon claimed a seat among the Ten Wizard Saints. In a world ruled by magic, Zorn walks the path of pure light, not as a hero, but as a domineering pioneer who stands at the forefront of a new era. ---------------------- Advanced chapters at p@treon

Transmigrating into the whimsical world of Gensokyo, Haruto thought he had it made. As the newly minted younger brother of the all-powerful Sage of Youkai, Yakumo Yukari, his days were filled with leisurely naps, teasing the local shrine maiden, and enjoying the peaceful life of a Boundary Youkai. But his relaxed everyday life shatters when a cold, mechanical voice echoes in his mind, forcibly selecting him as a player in a brutal, infinite-flow 'Death Game.' Thrust into terrifying horror instances where ordinary humans struggle to survive against malicious spirits and deadly puzzles, Haruto quickly realizes the game has made a fatal miscalculation. He isn't just some helpless mortal—he's a youkai with the power to manipulate boundaries! Armed with a spatial 'Gap' ability, an arsenal of overpowered talisman cards crafted by his swordswoman girlfriend, and the ability to drag the immortal, NEET Lunar Princess Kaguya into the fray as his personal meat shield, Haruto turns nightmare-inducing survival games into his own personal vacation. While other players scream in terror and betray each other to survive, Haruto is busy setting up folding chairs, sipping tea, and blasting ancient ghosts into oblivion with world-destroying Magic Cannons. But as the Death Game's instances grow increasingly twisted and intelligent, Haruto discovers that the game might be harboring a deeper, darker secret. With the ultimate powers of Gensokyo backing him up, can Haruto conquer the Death Game and uncover its true purpose, or will the escalating horrors finally find a way to challenge the ultimate cheat?

Matthew is your average transmigrator — except he's somehow ended up as a shareholder in Umbrella Corporation. In the Marvel Universe. Don't ask how. He doesn't know either. With Thanos on the horizon, the Avengers and S.H.I.E.L.D. breathing down his neck, and his fellow shareholders actively trying to kill him, things aren't looking great. His one saving grace? A system that rewards him for raising people's "Happiness Index." The catch: every reward the system hands out is a bioweapon. T-Virus. G-Virus. Extremis. Blacklight. The list keeps growing, and none of it screams public welfare. Fortunately, his system comes with a workbench — perfect for turning weapons of mass destruction into something a little more... palatable.

Reborn in the world of High School DxD… was that supposed to be a joke? Because I wasn’t laughing. Still, it’s not the worst place to end up—if you stay away from the supernatural, that is. Except fate wasn’t about to let me sit on the sidelines. When I woke up, I didn’t just get reincarnated as some random guy. No, I looked exactly like Nate Adams from Yo-kai Watch… complete with the watch. At first, I thought it was some kind of bizarre prank universe. But the Yokai didn’t see it that way. To them, I wasn’t just some kid with a fancy watch—I was their prophesied King, the one destined to restore their pride and lead them out of the shadows. Great. Another “Chosen One” gig I never signed up for. The Yokai treat me like royalty, Yasaka’s staring at me like I’m the moon itself, and the prophecy says I’ll fix everything that went wrong with their world. And honestly? I can’t just ignore it. Like many DxD fans, I hated how the Yokai faction got shoved to the side. Guess what, Devils, Angels, and Fallen—you won’t be able to ignore us anymore. With a harem of powerful Yokai girls (and maybe a goddess or two), I’ll carve out a future where my people won’t be treated like pawns or second-class citizens. And when I eventually cross paths with Issei Hyoudou, I’m not going to hate him. No, I’ll sit down with him and talk about what it’s like to actually handle a harem. Because unlike half the fandom who whine about him being a pervert, I get it. This is my story. This is the rise of the Yokai King. ----- MC: Nate Ship: Nate X Harem (because it's DXD No-NTR (No of the girls in Issei Harem is gonna be in Nate Harem) DxD X Yo-kai Watch

Death was his end… but also his new beginning. An ordinary man, ripped from his life by a heart attack, awakens in a world he once only knew from stories—a Marvel universe where movies, series, and comics collide, forming a dangerous and unpredictable reality. Now, trapped in the frail body of a fifteen-year-old homeless boy, with the Omnitrix strapped to his wrist, he carries a power capable of saving… or destroying everything. In a world where heroes are living legends and villains are threats that can level entire cities, he must carve out his own path. He’s not a spectator. He’s not a fan. He’s a player in the most dangerous game of all. To survive, he’ll have to become more than a hero: a symbol of hope. NO HAREM, MC HERO
