These are just some ideas I had for some fanfictions, mostly Harry Potter and Naruto fanfiction but may have some for My Hero Academia and One Piece. If you find one of these interesting feel free to use it as honestly I have severe ADHD and will probably never finish these even if I did start them. That is why I always will leave you, if interested enough, to use my ideas. At least that way I have the chance to see my ideas be brought to life and hopefully finished. So if you see one of these ideas as interesting and want to use it just let me know because I would love to read it when you do start on it :)

1.) Naruto and Wreck-It-Ralph crossover. This is an idea I had when I read about Naruto either stumbling into or summoning a creature from another series like one of the Xenomorph Eggs or the Zerg. Only in this it is a Cybug from Wreck-It-Ralph. In this I planed for Naruto to have just escaped the Villagers on the night of the Uchiha Massacre. Danzo would have a Cybug egg he got when he tried unspecified summoning. The egg would hatch and the Cybug would devour the Sharingans and the arm made from Hashiramas cells. The cybug would then escape into the forest where it would find Naruto and swallow him. Now normally this would cause the Cybug to absorb the boy like he did with turbo but the Fox intervenes and causes it to reverse making it so Naruto absorbs the bug instead and gaining some of the bugs features (Such as wings) along with the sharingan and wood release. He would have the ability to eat anything and adapt it into himself like when he eats ramen he could be able to bring out Ramen Whips from his fingers or something like that, Eats a kunai and is able to turn his fingers into blades etc etc.

2.) Harry Potter Puppet Master. This is where Harry makes dolls and puppets that his magic animates or brings to life. I got the idea from Sasori of the Red Sands in Naruto. Where Sasori tried to build parents a young Harry tries to make friends, literally. He gets this idea from either a puppet shop he stumbles on or comics/anime he saw his cousin reading or watching. So Harry gets a puppet or doll whatever he can find and wishes it was real and his magic reacts to his wish and brings it to life or just animates it. Harry would be a bit introverted and smart and would use his puppets for things such as survellience as I would have the puppets technically be part of Harry so anything they saw or heard he would learn about. It would probably end with Harry having a puppet army that could be used to take over the wizarding world. I would have Harry be a Slytherin though and start with small puppet but then have him make larger and more unique coughdeadlycough during his years of hogwarts after he uses money from his vaults to get materials to make said larger constructs.

3.) Devil Fruit Ideas. a.) Deal Deal fruit/Contract Fruit. This is a paramecia fruit that I came up with based on the saying about dealing with the devil. This fruit allows one to make bets, deals, contracts that are quite binding so long as two sides agree to the terms anything and everything the other two parties own can be gained. Anything from berries to crew to life span and even devil fruit abilities. Say someone makes a bet where the Deal Fruit user and some other fruit user and the other fruit user loses then the Deal Fruit user can either gain their DF ability or strip them of their ability and get the Devil Fruit. As I said anything can be gained and if you make your Deal Fruit user cunning enough he can trick people into verbal contracts or bets and then take everything from them. b.) Wish Wish fruit/Djinn Fruit. This fruit would do one of two things. One it would grant the eater one wish every year either on their birthday or the anniversary of the day they ate the fruit. Two it would grant the eater three wishes either by knowledge of the fruit or by summoning a genie. Now I would put limits on what can be wished for but it is up to you. But I would also have it be a "careful what you wish for" type deal. If anyone has watched Wishmaster or seen Norm the Genie from the Fairly Oddparents they will know what it means to phrase your wishes in a manner where it can't backfire on you. I would make it so the eater CAN'T wish to be the strongest but can wish to have unlimited potential. Plus my user could bring back the dead but it is one person per wish

4.) BNHA Quirk. Matrix Quirk which would allow the user to see the world around them as computer code. The user could change or manipulate said code to change the world around them or themselves. My user would change the 'Code' in himself to allow him to have at most 6 other quirks by copying the code of others or use his quirk to upgrade other peoples quirks. Such as Momos Creation Quirk could be upgraded to Alchemist which would allow her to not only create things from her body but also change her surroundings like in Full Metal Alchemist. Or Ochacos quirk would be upgraded to allow her to also increase gravity on the object she touches or to be able to freely manipulate gravity in a certain area around her body. Or take that Kurogiris quirk to teleport and change it to having a separate dimension where the user could store items. Etc etc.

Quirk: Data. Allows one to freely enter into cyber space and move through electrical currents. This was going to be the Matrix users mothers quirk and she would be Cyber Hero Porygon. Quirk: Ope Room. Basically this quirk gives the user all the abilities of the Ope Ope fruit from One Piece. This would have been the Matrix users fathers quirk also known as Operation Hero Frank N Stein. Quirk: Doppelganger. User creates a clone of himself. Whatever the clone learns the original will learn upon fusing back together. WARNING user has to fuse together with clone within a set time or clone may begin to experience it's own sentience. Based on Shadow Clones. Quirk: HIVE. User can absorb and store insects in their body and release them at will. User will have full control over the insects. I thought this quirk would be like the Aburame clans Kekkei Genkai or if you want it more powerful like the ability the MC from Death Mage Doesn't Want a Fourth Time where he can store really powerful insects in his body like that huge centipede that creates lightning

5.) Prank King Naruto. This one is how Naruto goes slightly insane but in a fun way due to some tragic thing that happens such as a mob. His goal isn't to become Hokage but to pull the ultimate prank that will go down in history not just in Konoha but in the whole elemental Nations. Naruto can manipulate the world around him like in cartoons, subconsciously, and would use seals to help him pull pranks. I got many prank ideas he would pull on others one being somehow getting the juubi in a giant sombrero with moustache. Or panting the Uchiha Distract pink. Getting the Hyuugas labeled as peepers. Placing a huge amount of catnip in the inuzaki compound etc etc. I would pull out some jokes from Hellsing Abridged and DBZ Abridged. Anyway so long as naruto is a prankster whose goal is to prank the whole elemental nations you can do whatever you want with him.

6.) Kissed Harry Emotionless Harry. This would have been after that trail in 5th year where they find him guilty because Dumbles doesn't arrive in time and they decide to give him a much harsher sentence because they are corrupt bastards. So Harry would get sent to Azkaban but one dementor would give him the Kiss either by accident or design. But due to the Horcrux Harry Surives with most of his soul due to the Horcrux holding part of it back. This has two effects one even though Harry wouldn't be a souless husk he loses the vast majority of his emotions. Two it makes the dementor his Horcrux since it contains part of his soul rather than the full thing. Though the second thing is only something I recently thought of applying. Harry would then befriend Bellatrix as he fakes his emotions. Voldemort would come and break his followers out and Harry would go with him since he no longer feel hate or anger towards the dark lord and the Dark Lord finds this new Harry Potter intrigueing. I was going to have Voldy and his death munchers open Harry's cell only to find him sitting there with a large blueberry muffin in his hands thus confusing them all. He would then get up and act real excited to see them and either kiss Voldy or Bella. Then be crucioed only instead of pain Harry would feel pleasure from it. Anyway it would be a slightly insane and apathetic Hary trying to gain his emotions back with perhaps some romance thrown in.

7.) Harry and D. Gray Man Crossover where Harry becomes an Akuma after trying to bring back Sirius. He retains his sense of self because of the Horcrux taking Sirius place as the battery and tethering his own soul to the mortal plane due to the prophecy. This causes either Harry to level up instantly to a higher level due to the amount of corruption in Voldemorts Soul or has him level up quicker. You can do whatever you want with Akuma Harry but he still has to kill people. Kill anyone hell if you want Harry to still be a good guy make him only target evil people. Or you can make Harry be the Earls favorite with all kinds of Harry and Noah interactions. Due with it what you will.

8.) Naruto SI. This is an idea where a sniper/hunter dies and is reincarnated into the Narutoverse as a Hyuuga. Instead of Gentle Fist he creates a bow (Or gun) and uses his eyes to snipe down enemies from affair. I mean really the Hyuuga see 360 degrees and can see incredibly far distances and through objects so I think a sniper Hyuuga would be bad ass. Though my Hyuuga OC would have been born outside Konoha due to a main branch members drunken escapede with a hunter clans female who had a dojutsu that allowed her clan to see far distances and air currents.

9.) BNHA Izuku with the quirk Sin of Greed. The quirk would grant him all the abilities, other than immortality, of Ban from the Seven Deadly Sins. He can use this to take items as I think this quirk would make him be a Kleptomaniac. He can use it to also temporarily take the quirk of others or their physical strength, stamina etc. I think the closer he would be to a target the more he is able to take from them. I figured a Hero would catch Izuku stealing absently and confront him but instead of arresting he puts him on probation and enters him in UA to use his quirk to be a Hero rather than a thief.

10.) Twins. I had this idea for several series to have a reincarnation of someone into a world and be the twin of a character. Separated Sands was all focused on the twin brother of Gaara who was given to Konaha as a political move but in reality was moved because they thought Shukaku may have tried to escape into the Twin to break free of the seal. My MC would have a Metal Release Kekkei Genkai which allowed him to absorb and create metal from his chakra. He could create any metal he had absorbed before. He would also have a Psychic Link to Gaara and by extension Shukaku.

Separated Seas was about the twin of Ace who got left behind because of a nurse misplaced him and then adopted by Vegapunk he was going to have a DF called Void Void Fruit which gave him some power of space such as a storage space, allowing him to Void Walk to transport himself and objects to any place he had seen with his own eyes and allowed him to negate the DF abilities and Haki of those he touches. He would also have the ability, when he got stronger, to Void the DF Ability of others forever. He would have gone off to be a Merchant with a large empire.

Then Separated Snows was about the twin of Ye Ziyun from Tales of Demons and Gods. He separated from the group when the city was abandoned and went on his own where he found a temple with an Art that allowed him to use a Yin Yang based art which allowed him to have two Spirit Beast souls so long as they are opposite such as fire and water or dark and light. As he trained in this art his soul beast would evolve and grow stronger. Then he would fight Nie Li due to him having entrusted Nie Li with his sister and finding out she was dead set him off. Though the two would team up against the Sage Emperor and due to certain things he would be flung back to his younger selfs body like Nie Li. He vows to protect his sister this time and hopefully find some happiness himself.
