Hay guy's just want to tell you that I'm thinking of starting a new story once I've finished the first volume of (Reincarnated as the demigod of Fenrir). of course the story will continue after I've thought of an idea for the second volume since I've just been winging it this hole time without a ending in mind, but I digress.
I have a few ideas all you have to do to pick is just comment the number beside the idea.
(1)... The MC dies saving a stray dog from a bear and meets the god of dogs, as a think you for saving one of her people she grants him some wishes and the option of what world to reincarnate into, after making his wishes and picking the world of Naruto her begins his new life but what the goddess forgot to mention was she can only reincarnate him as a dog, he then strives to become the worlds strongest, respected and feared ninja dog in all of the hidden villages.
(2)... In the year 2025 once everyone was sure the pandemic was over it happened a world wide message, the message read "Congratulations Earth No-972323b5!c, you have been selected to receive the system", this system gave ordinary people unimaginable power and the world fell into chaos, as the world fell around him the MC with no time to open his new system and gain the same unmatched power he ran for shelter to escape some people but little did he know what he ran into was an abandoned prototype cryo facility, he is then steps into a cryo chamber trying to hide but when he leaves the world has changed. long after what's come to be called the "System wipe Riots" du to all knowledge in the past being destroyed nobody knows what happened. The MC hinds himself lost in this futuristic world filled with flying cars, futuristic gadgets and aliens? but from what he can tell is that there is a new jobs revolving around the system though people seem to have forgotten how to abuse the system like the people were back in his time.
(3)... Truck-kun seems to have it out for this MC but he survives... forrrr~ a few seconds before being hit by a bigger Truck-kun and dying, as he walks up the narrow path to heaven he is accidentally knocked off and falls into the lake of reality's and collides with another soul from an unknow world and fuses together his mind being the strongest of the 2 and the others body being stronger than his, he transmigrates into the world of "Star Wars" in to body of a... WHAT THE HELL AM I, AM I A FURRY?!? WAIT NO, WHAT THE BEEEEEEP AM I?!?!?! (NOTE... any swearing will not be censored in any of my story's don't like that tuff you're not the one writing HAHA)
(4)... whilst climbing mount Everest suddenly truck-kun comes out of nowhere and kills the MC he then meets a very peculiar god who seems to be obsessed with slot machine's which he uses to decide on his species, powers/ability's and even the world he will reincarnate into, he then pulls the lever and his power's/ability's and world are decided. "Okay cool the world of Ben 10 I can deal with that It's been awhile but I should remember most of the plot... WAIT!... I'M A POKEMON??? (NOTE... If picked you'll have to decide whether the story starts at the beginning where ben gets the omnitrix or the story starts where ben puts the omnitrix back on)
(5)... Dying alone of old age in a home, the old man meets a god who tells him the there is such a thing a good and bad karma, too much bad karma means you go to hell for a few millennia and a lot of good karma means you have a choice to either go to heaven for a few millennia or reincarnate, the old man chooses to reincarnate, unfortunately there is a price, every wish costs karma points and yes that includes picking the world, (karma points being the amount of good karma points minus the amount of bad karma and that's how much you have to spend), and the old man only had enough karma points for either 2 wishes or 1 wish and a choice of what world he goes to, being an otaku in his past life he chooses to reincarnate in the world of MHA and surprising the god in front on him by choosing luck as his wish.
(6)... A master at mixed martial arts win's the world tournament for the 8th time in a row which some people weren't very happy and sent someone to assassinate him and because he cant dodge a bullet he dies and meets a ROB which gives him 3 wishes and will be reincarnated into a "random" world, which turns out to be "Highschool of the dead", his wishes being, 1. his muscle memory and skills from his past life. 2. a pair of gauntlets that can absorb impacts and dish out a lot of damage. 3. super fast proception, though processing and reaction speed.
(7)... in a world where our MC dies and is reincarnated into a... normal?... world?... after years of going through life like normal he starts to notice things the seem familiar to him... then one day as he was at his job at a wildlife sanctuary feeding the wolves and listening to the radio he hears something oddly familiar... "We're here at Star labs for the grand opening of the practical accelerator"... Star labs? where have I heard that bef... THE FLASH!?!? OH SHI(*BOOOM*).
(8)... While sky diving the MC gets a notification that reveals that his GF cheated on him and is dumping him, being an orphan and nothing left to live for he then decides not to open the parachute and plummets to his death, he then wakes up at an office desk with a man in a business suite, apparently he fell on a guy who was about to kill someone very important for the future of that world, as a reward he is given a chance to reincarnate into another world of his chose with his memory's in takt and three wishes , he choses to reincarnate into the world of "Fairy Tail" with the wish's of all of Gojo's power and knowledge of six eye's and limitless which was denied but he was allowed his appearance the second wish being special and or dimensional magic which was surprisingly approved and the last whish being the most loving family he can get but little did he know that that last wish would have 2 outcomes that he didn't see coming.
(9)... the MC dies in the army during a fire fight he was sniped and was sent into the line of reincarnation and meets the god in charge of the reincarnation cycle, he is then given the chose of the world as well as 1 wish, he then picks the world of Pokémon but choosing that world resulted in 2 randomizer wheels appearing 1 being whether or not he will be a human or Pokémon, with his fingers crossed hoping to be human so he could be a trainer, unfortunately it landed on Pokémon he then sighs accepting his fate and makes his wish, wishing for an OP Pokémon system that he can acquire item's through a shop as well as through levelling up and quests, he then spins the wheel to choose what kind of Pokémon he will be, as it slowed down and stopped it landed on ??????, then begins his new journey as a Pokémon but he forgot to specify where and when he wanted to reincarnate.
(10)... the MC is a gamer playing professionally and winning prizes such as money, medals, certificates and popularity amongst other gamers, unfortunately he is seen as a waste of space to his parents, the only person in his family that sees any worth in him is his step sister from his mother's third marriage, who like's him a little too much, unfortunately for him he dies in an "accident", he then blanks out and wakes up in a forest in a world of monster's, dungeon's and adventurers with a system there's just one problem... I NOT HUMAN!?! little did he know that was the least of his problems, in this new world he will meet someone he knows very well.
(11)... The MC dies of a heart attack and meet's the god of reincarnation and is given 3 wishes... or that's what should have happened, apparently the god of reincarnation was busy and didn't have time for him, he totally wasn't slacking on the job... anyway he is reincarnated into the world of "one piece" in the forest of Dawn island as an orphaned kid without any wishes or badass powers, surviving in the forest for awhile unaware that he was in the world of "one piece" he finds a strange looking fruit, starving he didn't hesitate to eat it not caring for it's taste, after awhile of surviving he off the land and stealing from people unaware of the world and what he ate as well as the changes that it caused, he make's a big mistake by trying to steal from an old man walking in the forest and get's a fist to the head, he then realised the world he's in as well as what it was that he ate when seeing the old mans face, it was Garp the hero of the marines, Garp then drags he off to the bandit's where he meet Luffy, Ace and Sabo and practicing his Zoan "Devil Fruit" (NO SPOILERS), deciding to become a pirate and start his own crew, as a captain his journey begins.
(12)... our generic Otaku pre-protagonist crosses the road after shopping and is hit by Truck-kun and is reincarnated in to a fantasy world of magic and mythical beast's, she is then reincarnated into the royal family Phenex of the Phenex Kingdom, she was born as the daughter of one of the concubines and is the one of youngest of 14 children, in this world when a child come's of age they awaken power's that are a representation of that persons soul, these power's can be anything from controlling an element and even manipulating the law's of this world such as life, death, time, gravity, etc. and even just the power make your skin smoother or the power to blow bubbles. although the power's can vary person to person most of the noble family's have a power that their family is known for, the Phenex family was known for is power to control the element of fire, but what will happen when the power she awakens is not the typical element of fire.
(13)... waking up in a dark place, our MC is surprised by a screen that popped out in front of him out of no where to asking him for what world he wants to go to and gives him 2 wish's, he chooses to go to the world of Naruto and wishes for the chakra and life force of the Uzumaki clan, the kekkei genkai version of the op-op devil fruit, after choosing his wish's he is then told that the world will have to choose when and how he receive the wish's.
Those are all my ideas so far but if I come up with more then I'll put them on the list.
