Harry Potter • 2893 stories • Updated 30 Oct

Hot chicks with pointy sticks meet young wizards with, er, pointy sticks. Lots of pointy stickiness all-round as Harry, Ron & Hermione get a little help in the war against Lord Voldermort. And what will the Ministry of Magic make of wandless witches and DADA teachers that take a more direct approach to the defense aspects of the job?

On the other hand, see what happens when the Hogwarts student body gets exposed to not quite so muggle life in Sunnydale. All this and more to be found in our massive collection of Harry Potter crossover stories.

Hello All,

I'll get straight into it. The 'idea' in question is that Xander Harris is the last Scion of Family Black. He is the Son of Regulus Black and Satele Shan. Yes....The same Satele Shan from Star Wars the Old Republic. Basically, sometime post War she crash landed on Earth with no way to return home. Regulus found her and was immediately taken with her strength, her power and her beauty. Hell fell in love with her and the attraction was mutual. They secretly wed and had a child together. Alexander. But before they could run away together tragedy struck. Regulus died (as per Ca...

So what if Lilly Potter had another sister besides Petunia? What if that sister was Jessica Harris?

OPTION ONE: In an effort to make Harry's life better yet still provide him with Blood Protection, Dumbledore locates (Season 5) Xander in Sunnydale who takes in (Post Book 1) Harry?

OPTION TWO: Dumbledore thought that having the Boy-Who-Lived halfway around the word would be an added protection so he was sent to live with his other aunt and his cousin Xander. *Follows regular timeline for both*

The Dursleys decide that they can’t care for Harry. This reasoning must (for once) put the Dursleys in a positive (or at least neutral) light.

Possibilities:
1) Vernon and Petunia don’t feel qualified to raise a young spellcaster and so they send Harry to a distant cousin of Lily’s that is a spellcaster (Options: Willow; Tara; Mrs. Maclay; Amy; or Catherine)
2) Vernon and Petunia feel that magic is evil and so they abandon Harry in a church or some other place of worship, hoping that the religious person in charge will be able to cleanse the evil from the child’s soul ...

Must have:

A one-night stand between Buffy and Harry you can treat however you wish, i.e. a drunken fling, or just two stressed out Chosen Ones trying to relieve pre...

THIS IS THE SAME CONCEPT THAT MARVEL COMICS/DC COMICS HAVE USED. YOU MUST RECREATE THE CHARACTERS INTO A NEW AND DIFFERENT VERSIONS OF THEMSELVES. THIS CHALLENGE DOES USE SPECIFIC CONDITIONS THAT ARE THERE TO BUILD UP A FOUNDATION FOR YOUR STORIES TO START FROM.

Conditions:

Harry Potter's first name must be Henry, with Harry as only a nickname his friends use.

Hogwarts School for Witchcraft and Wizardry must only accept children from Ancient and Noble Houses; the only exception to this rule are first born witches and wizards attending under a Scholarship.

Harry leaves the wizarding world after he defeats voldemort but before he leaves he gets one or more degree in computers from a pensive. Also give him special forces training that he got during the war. So the premise of the story is that harry gets PTSD from the war so He leaves the Wizarding world because of the fame. He eventually befriends Neal and maybe even start to date. Harry is sharing a two bedroom apartment with a US Marine who is on leave and is helping him get over it. Harry is running a small computer company along with the marine who occasionally helps out. So bad guys kill mari...

OK, simple idea here Hermione Grangers parent are not exactly who she tells everyone they are, they are in fact one Alexander Harris and some female of the writers choice though my personal preference would be for one of the girl Scoobies. The whole my parents are dentists thing is just a cover story as they are concerned that some Wizards might come after her even more than the usual "supposed" muggle born if they new she was connected in any way to the Council and Slayers.
One of the results of Hermione's parents being who they are is her knowing a great deal more about the Wizarding W...

Magic learns, spells become common, because at they're cast they become easier to cast. Magic becomes predisposed to respond to certain things in certain ways. Harry's magic has been trained too. His mother's 'ward' that saved him from Voldemort was simply her teaching his magic how to respond to an attack. And his magic learned... attacks were meant to be hit back even hard, much harder.

It was a couple of years before his magic recovered enough from his first outburst, but oneday when Vernon raised his hand, like He-who-must-not-be-named, Vernon, ceased to be. No body, simply V...
