that Slytherin au

So remember that post a while back where I had a harry potter au for one piece where all the Strawhats were in slytherin due to their strong ambition present at an early age to achieve their dreams? No? well here it is anyway lol

Check out this post for some more reasoning behind the idea – note that I do headcanon some characters to not be slytherin, but for the sake of this au and the actual technicalities of the Sorting Hat theyre in Slytherin.

Here we go!

AU will start off with Luffy as a first year, and all canon age differences, meaning Usopp is in his grade, Nami’s one year older than them, Sanji and Zoro above her, and the rest Adults!

Save for Chopper – a special case, a mythical creature raised as human by Hiruluk in the northern mountain range. He looks somewhat more human than canon but is definitely a reindeer. When Hiruluk died and he was given to the care of Kureha, she sent him to Hogwarts (after a few years of learning from her) due to his wish to know more. He was accepted as a political ploy as an olive branch to other magical creatures – ‘ we accept you!’. He doesn’t care. He might be furry but he’s here to learn and be the best healer ever!!! Hence, Slytherin, the boys got ambition and needs some powerful families to back him up! He is in Luffy’s grade, even though he’s younger (technically)

The biggest reason for the Strawhats to be in this House is because of their ambition - but there are other reasons too!

Sanji is from a family of Gryffindors – heroes who are anything but. He wants to be the exact opposite of them in any way he can. When Zeff adopts him, he unlearns his family taught prejudices against Slytherins and when he goes to Hogwarts, tells the sorting hat in no uncertain terms that he wants to be in Slytherin.

Nami herself is cunning, and I would place her in Slytherin even if this wasn’t a Slytherin Au. She’s the perfect slytherin down to the T except for one thing – she doesn’t know her magical origin, as she was adopted at a young age. She gets a lot of shit for that, which she gives right back, as well as taking some money along the way! She also doesn’t fall in with the Magic is Superior ideology that many of her peers have – magic didn’t save her town, or Bell-mere, or her orange trees, magic isn’t superior. Magic is a tool to her, not a way of life, and science can help a lot! For instance, she made the Climatact Spell Set, with help from Usopp, which combines her knowledge of weather patterns, the environment, brief weather spells, and heat and cool manipulation spells, to create weather based attacks. For instance – it takes a lot of energy to summon and sustain/direct a storm… but if Nami can create one with use of low power cooling/heating spells and the environment – she can do a lot.

- More Below!

A zoro that is Cursed to always be lost is something that I’ve seen often and Im HERE FOR IT! If someone could direct me to the original creator of that headcanon I would love to credit them for it! To Be Clear AGAIN this idea is not mine, but I want to credit whoever’s it is because I love it.

That aside, Zoro is like Nami in that he doesn’t know his magical heritage. However, as a child he got the misguided idea that more wand equals more power, which he somehow manages to make actually work. Thus, Zoro has three wands, each with powerful beginnings. Im thinking powerful dragon heartstrings core for one wand, Thestral for Kitetsu, and Rougarou hair for the last sword – Zoro’s a bloodthirsty kid and he needs some bloodthirsty wands :/

Usopp’s a halfblood! He’s kinda scared of Hogwarts as his magical parent (Yasopp) has kinda been outta the picture for the most part, but he’s ready for this!! As soon as the kid practically vibrating with excitement to his left doesn’t explode. Usopp originally desired to be part of Gryffindor – house of the Brave, right? But after talking to Luffy, he’s not so sure. He wants to be his own hero – all on his own, not because he part of the hero, brave house. When Luffy is sorted before him into Slytherin, Usopp makes the descsion to follow him, and follow his goal. He’ll show the world he can be the best!!

He grows to be really good at herbology and potions – an odd mix, but you know whats odder? Mixing the two to chuck at people for pranks then turning it into your fighting style. Go Usopp!

Brook’s a cursed ghost – he’s bound to his living body, but the body’s just bones and bones lol. He makes it work – people know him first as the Soul King after all! He can barely remember his school days, but hes vaguely sure he was in slytherin – he remembers many parties held in dungeons, looking out to the lake for sightings of a curious aquatic beast (Laboon!)

Franky’s still a shipwright, but of ~magic~ ships. His brother’s ships are better known, but his are more sought after by… certain people (more on that later.) When he was a kid, he walked straight into Hogwarts, looked for the table that had the people who would buy his stuff, and told the sorting hat he wanted to go there. Later, he runs more with the Gryffindor crowd, regretting his choice, but when he makes friends with a first Year who tells him where to find some Adam Wood in the Forbidden Forest, he stops regretting it so much.

Robin has a very shady past, and she’s only at Hogwarts for a year before disappearing into the world. She has an odd type of magic, somewhat like pareseltoungue, that allows her to read coded and ancient languages with some studying (our girl still puts in a lot of effort though!) She reappears many years later during Luffy’s first (possibly second) year, and becomes the new history teacher (sorry professor Binns!) People find her scary and suspicious, but Luffy likes to talk to her after class, when she tells him history more like a story than a lesson! She’s very good at duplication magic.

LUFFY. This boy. Where to start – he’s from a pureblood family, not that he cares, and has some serious magic talent – which he plans on using to travel the world and find the mysterious One Piece – a fabled artifact said to have one’s wishes granted. Luffy wants it to be free (his home life with Garp isn’t very good.) He has a couple famous brothers who have been through Hogwarts – Ace and Sabo, both Gryffindors and pretty big shots around Campus. No one knew they were brothers til Luffy busted into Gryfindor Dorms one night and looked for them. Luffy is exetremly good with nonverbal magic (something in this universe that will be elaborated on, as it features into Nami’s magic as well), not so much with verbal as the pronunciation trips him up. Potions is also hard and if it were not a required class he’d have been kicked out.

Will touch on Jimbe later once I figure him out

Now. Perhaps you are wondering – why do a bunch of kids have developed fighting abilities? Well – take a look at the plot.

This takes place not only in a Harry Potter setting, but in Harry’s own world as well. Meaning – Voldemort is rising, Harry’s still the chosen one, yadda yadda yadda. But do you honestly think that Voldemort is the only magical evil? That there isn’t a magical underworld not involved with his horrible schemes?

Cause there is one – and Luffy and crew are neck deep in it. While Harry and co. are off fighting Voldemort, Luffy is ‘sneaking’ around fighting big time criminals.

Imagine – this eleven year old child comes up to you, a big mob boss, and absolutely destroys you. That’s Luffy.

Underage Magic? You think Garp, head of something or other in the Ministry of Magic, is going to stop that from training his criminal grandsons to be the best Aurors they can be? He knows how to undo the spell (there must be something at Hogwarts that blocks the ministry from being informed of spell use during the school year!) and Luffy has been casting magic like it was second nature since he was real young. He’s taught it to his friends too!

So plotwise, its basically the school reacting to the Straw Hats, who don’t seem to be friends but are, the odd noticings of what their doing while Canon plot goes on, and the inevitable suspicion from Harry.

But oh? What about the ship thing? What’s Franky Doing with that?

Luffy is forever a pirate – and the sea is one magical thing I have yet to be seen explored in the Harry Potter Universe. Therefore – free realestate!!! Luffy’s going to be a magic pirate when he grows up, he’s been telling everyone this since he first met Shanks, and maybe no one believes him now but it’ll happen! Magic Pirates!! Yay!!!

That’s all I have for now, so send me questions if you have any! I might make this into (another) drabble series, or maybe just one big one shot. We’ll see!!!
