How can I start writing a Supernatural alternate universe fanfiction?

25-year-old Albion lived an unimpressive parasitic life of a NEET and otaku, leeching off his loving parent's allowances to enjoy watching animes, reading manga and novels at home. When faced with the cruel reality of contracting cancer through smoking, he selfishly ran away from home and sacrificed his life on a strange day of drastic changes. 'Since I'm going to die anyway, let me save another life in exchange.' Those were his thoughts before shoving a person out of harm's way and getting struck by a truck. 'If I could get a second chance, I want to live a fulfilling life and not waste it like this.' However, Albion's new life resolution was quickly challenged by a stroke of divine providence. "What? I'm not dead yet? Holy cow, I transmigrated into the body of a notorious hidden boss who controls half the world's wealth in an alternate universe after he failed his heavenly tribulation? I never have to worry about money? I can live forever? Lucky me!" Albion thought he had shot to the peak of life, but he could not be more wrong. The immortal body was too strong for a mortal soul like him to control. He can only move for 5 minutes a day! He became immobile and paralyzed for the rest of the time! The Four Horsemen of the Dark Emperor thought he was crippled and turned on him! They couldn't kill him physically due to his invincible body so they dropped him to the bottom of the ocean to drown! His body was immortal. He could not die. Thus, he lived the following life in the dark depths of the ocean before being swallowed into the stomach of a giant sea serpent! Before he could enjoy his new life, he had sunk to the lowest point of his life, literally! However, the world rapidly changed after the notorious True Immortal disappeared for two years! The Apocalypse arrived, and so too, the System! Ding! [You have slain a Lv.1 ancient sea serpent. 100 EXP has been gained.] [You have leveled up.] [You have become a Lv.2 Hunter.] [Title acquired: Hunter.] Albion: ??? "Did the sea serpent get food poisoning and died from eating me or something?" Albion wondered in the pit of the sea serpent's stomach. [System calibration complete. Goldfinger has been activated.] "Never mind, my time has come! With the system in hand, I will take back everything and rule the w--wait, what? This body's cultivation needs to be sealed in order for me to move freely without impairments?" "Sigh, forget it, ruling the world is too hard. I'm a wanted man anyway. Let's just hide somewhere, watch my animes, and reading my manga and novels..." Albion was nerfed harder than the Big Bang at the beginning of time. However, what's his, will still be his. "Until my soul becomes strong enough to fully wield this power, I'll just treat it as a 5-minute Super Saiyan mode I can enjoy once a day..." He was not the Dark Emperor, but the Dark Emperor was now him. The Four Horsemen that turned on him, their day of retribution will come! Little did Albion know, the world had more things in store for him than his quest for vengeance. The dimensional rifts that appeared everywhere and the interdimensional creatures that spilled forth from there are actually...! Find out on the next episode of drag--Ahem, to be continued. =====Author's Note===== [Currently on break] Feel free to check out my other book, Prime Originator (also my first work). The genre is completely different, so you may or may not like it and vice versa for readers coming from there :) You can join me on discord at the link here; https://discord.gg/9SUWMPZ =====DISCLAIMER===== I do not own the cover.

A man from an Earth gets the choice to start over in any Universe and chooses an Alternate Pokemon Universe. Let us see if his journey to the top is succesful and the impact he will have on his new world. Pokemon is owned by Nintendo, Game Freak and Creatures Inc. I just use their sandbox for the plot of my MC and my OCs. This will be a "slow" paced story, in fact it's "super slow paced", so please don't expect the MC to directly start his journey in 20 chapters or so, actually multiply that by like 15. A lot is going to happen before that happens. The first 10-20 chapters or so are information heavy, depending on what kind of reader you are. I try to keep my chapter length between 2000 and 3000 words per chapter. My release rate is 4 chapter/week for now. I have a patre*n for those that want to support me with access to some advance chapters as a thank you. patre*n.com/Azrail93 This is an alternate pokemon universe so there will be differences to the games, manga and anime. So if something in the story is different it is most likely on purpose. The original sources are seen as suggestions not laws. Differences can be: Type variants, evolution conditions, strength mechanics, world building and more. If I am at some point asking for reader input I will do so but otherwise I will ignore most suggestions. So please don't spam things like catch this pokemon or do that next. I have my plot planned and external input will be considered when asked for. If I see a suggestion that I believe fit my plot flow I will use it and will credit the commentor. Comments on spelling and grammar mistakes are welcome. I will try to correct said mistakes with time. Constructive criticism will be read and considered. Insult and hate comments will be ignored or deleted depending on severity. Readers naturally can comment their dislike but one worders will be ignored. If the reason for the dislike is explained I will read it. Like previously mentioned pure insults and hate comments will be ignored or deleted. The same is true for simple hate reviews or insulting ones. Reviews complaining about something I warned about, such as the slow pace, will be deleted as well.

Tang Zhen transmigrated to an apocalyptic world, where humans struggled to survive in various buildings that they built because the ground was covered in lethal dangers that were invisible to the naked eye. Tang Zhen transmigrated along with his mutated cell phone that was packed with miraculous applications. There were all kinds of cities – some could fly in the sky, some could submerge into the ocean while some could become invisible – and shocking secrets were hidden within them. The power of Tang Zhen’s city was… He established a city and quickly leveled up his army with speeding tools. Then, he dominated this alternate world by seizing other cities. He sat at the very top. Beneath his feet was a vast floating city guarded by dragons and surrounded by angels. Countless cannons were also set up at various corners of the city. A million miles ahead, in the depths of the ocean, there was another city as large as a continent awaiting his conquest.

"In the unforgiving corridors of time, I was brought to the brink, my life teetering on the precipice of destruction. But fate has granted me a remarkable opportunity – a return to the past, a chance to rewrite my destiny. Brace yourself, for when our paths cross once more, the world will bear witness to an unrecognizable future!" Enter the realm of Alternate World, a virtual playground where mere mortals are elevated to the status of gods. The moment this game touched the lives of players, our world, our very existence, was irrevocably altered. People discovered newfound abilities, and playing the game became a way of life, a livelihood. Among those players was Manato Tsukasa, an unwitting protagonist whose life was thrust into turmoil on the eve of his wedding. In the shadowy depths of night, enemies emerged, determined to snuff out his existence. He stood on the precipice of death, only to be granted an unexpected lifeline, a return ticket to the past. With the past before him like an unwritten book, Manato seized this extraordinary chance with relentless determination. Armed with the knowledge of his past mistakes, he embarked on a journey to exact revenge upon the architect of his misery. The game that had once been his escape from reality now served as his crucible, transforming not only the gaming industry but also the very fabric of our world. Yet, little did Manato suspect that Alternate World held secrets far more profound than any player had ever imagined. The game's mysteries ran deep, and the truth, obscured beneath layers of illusion, remained tantalizingly elusive. As he delved deeper into the game's enigmatic depths, Manato would soon discover that the lines between reality and virtuality were destined to blur, forever changing the course of his life and the world itself.
