After an ordinary guy from his world wakes up in the body of Ash Ketchum the night before his Pokémon journey begins, he realizes he's not just in any world - he's in the world of the Pokémon anime, standing in Ash Ketchum's shoes. Armed with years of fan knowledge, Yuri is determined to rewrite destiny, make smarter choices, and blaze a path to becoming a true Pokémon Master. But in a world where every choice has consequences, one wrong step could change the entire story... for better or worse.

On an ordinary afternoon at the Ninja Academy, Naruto Uzumaki accidentally unlocks something impossible - the Future-Life Simulation System, a mysterious power that lets him live through countless lifetimes, each one testing his choices, skills, and destiny. Every simulation brings victory, failure... and death. But each one also leaves him stronger, smarter, and more determined. To become Hokage, Naruto won't just train - he'll rewrite his fate one simulation at a time. When the line between reality and simulation begins to blur, what kind of shinobi will he become?

Reborn into the world of Bleach, I became Kyoraku Shunsui's nephew-Kyoraku Shimo. I also bound a check-in system: each time I check in, I grow stronger-and that's how I obtained a one-of-a-kind Time-Type Zanpakutō. Time Reversal, Time Stop, Severing Timelines... But in a world as dangerous as this, for the sake of survival, I decisively chose to join the Fourth Division. What? You think I joined because I'm lusting after Captain Unohana? Nonsense. I just want to deepen my skills in Kaidō (healing arts)! ...Damn. She smells amazing. Really *What to Expect: -Overpowered MC -Broken System -Time-Space Abilities -Multiverse PS: There is World Travel here. Dont limit the power scaling on just bleach verse alone.

Ken transmigrated into the world of Naruto and took the place of Nawaki, Tsunade's younger brother who was originally fated to die during the war. However, he gained a strange "Lord God System" that allowed him to designate others as his "Reincarnators"-he could assign them missions, essentially turning them into his workers, earning him points in the process! [Mission Objective: Act out an ecchi scenario with your own brother.] [Mission Reward: Wood Release Kekkei Genkai.] [Mission Failure: Erasure.] Tsunade, who had been forcibly turned into a Reincarnator, stared at the system prompt with a deeply conflicted expression. After a long silence, she picked up the phone. "...Little brother, come over here for a moment." "Hm? What is it, sis?" "...Forget it. I'll come to you instead..."

Naruto Uzumaki-Namikaze a child neglected and scorned by his family and village he found himself in a strange forest. There he had met someone who like him was alone and sad.

( Credits to @AustinKelly526 for the idea ) Y/N thought he signed up for a normal job. Something quiet. Something safe. Something that didn't involve angry gods, sword-wielding tsunderes, and overdramatic kings with god complexes. But no. He's not a Master. Not a Heroic Spirit. He's... the therapist. Now trapped in Chaldea, Y/N has one mission: fix the Servants. (Or at least stop them from killing each other in the hallway.) From calming down Jeanne Alter's weekly meltdown, to dodging BB's chaotic matchmaking attempts, to surviving "family therapy" with Karna and Arjuna, Y/N's job is pure madness. No powers. No weapons. Just a clipboard, coffee, and sheer mental willpower. Pray for him.

Fujimaru Kyouya, a 17-year-old high school student, suddenly finds himself transported to another world, equipped with the "Hero Simulator," a mysterious system that shapes his destiny. A/N: This is more of an AU but might follow some historic events.

What if Issei had manifested his sacred gear earlier in life? What if he and Ddraig became friends with Great Red before meeting Raynare? Trained from a young age to be a badass delinquent and the wingman of Great Red, Issei kept his power a secret in anticipation for the day he would finally fight the white dragon emperor. Things don't go quite as expected however, when his infamous rival turns out to be a beautiful silver-haired foreign girl who just transferred to Kuoh Academy with her pale blue-haired friend. How will the devils and angels deal with three extremely powerful dragons going to the same high school? ---------- I do not own anything everything goes to it's respective owner.

Inspired by Arsenic Blues by 11QueenSupreme11 and Young Gods by phoenix1770, but with my own plot. This is a mix of reactions (WTS/WTM) and story. What happens when Percilla "Percy" Jackson got kidnapped by an alternate version of her father Poseidon that is more fearsome, cold-hearted, and bloodthirsty? How did he know about her? Why does he desperately want to claim her as his? Read and find out. Warning: Mature themes and some bad grammar and mistakes (I am not a pro writer). This is my first crossover so please go easy on me. It has been a while since I read the PJO series. *Cover art not mine* Percy Jackson belongs to Rick Riordan. Shuumatsu no Valkyrie (Record of Ragnarok) belongs to Shinya Uemura and Takumi Fukui.

Percilla Rhea Atalanta Jackson has always gone through hardships since the day she was born. Nothing was ever easy and life became more and more cruel as she got older. From being the youngest hero to have ever made it this far to the most powerful of demigods, from a Legendary hero to an enemy of the Gods, from friends and love to betrayal... and finally the last straw was the death of her baby sister and step father. She couldn't take it anymore how long does she have to be the puppet of the Gods and yet suffer because of them, unfair justice... she hated Gods. All of them, some day she will have her revenge. . . . . "Are you Percilla Rhea Atalanta Jackson?". A tall beautiful woman with flowing midnight blue hair and hair pinned back on the side with a wing shaped hair pin asked. "Depends on who's asking". Percy's eyes narrowed as the intruder gave her a calculative look before giving her a friendly smile which Percy wasn't gonna fall for. She didn't trust this strange woman. "I am Brunhilde, the eldest of the 13 Valkyrie sisters and nee-". "No". Brunhilde's eyes widened in surprise as Percy glares at her with hatred and hostility. "Look here woman. I know what you are and I don't give a flying fuck, I'm not helping or going on another quest just so your lazy devine ass can sit around and do nothing. You divine beings are all the same". Her usual sea green eyes glows, like the sea beautiful yet held deadly intent. Brunhilde shivers, she was playing on thin ice and she knew it. Although she hates to admit it, this girl frightens her... just like 'him'. Unpredictable.
