Harry Potter • 2905 stories • Updated 25 Jul

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.

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...

What if Harry Potter tracked down Buffy Summers to help her with her prophecy after he finished Hogwarts. Move forward several years and Harry and Buffy were knocked into the Past.

Requirements

When Harry and Buffy end up in the Past they are told, by the powers, that they are not allowed to make contact with any Slayers that had died in their time nor can they enter the British wizarding world.

Buffy and Harry adopt Faith.

Notes

Whether Harry and Buffy save James and Lily is up to you.
Whether they move to Sunnydale and meet the younger Willow ...

Once JK revealed that Snape came from a non-wealthy background did you think that he would want to spend most of the summer in "that house."

As a potion master it would make more sense that he'd go on day trips (at least) to find rare potions ingredients that grow during the times that Hogwarts is closed during the summer.

Willow retired from the demon hunting business and moved to a nice quiet dimension to raise her kids. Unfortunately, just because there isn't a large demonic presence doesn't mean everything is guaranteed to be a bed of roses.

One of her daughters rebelled against their atypical upbringing, probably because her younger sister seemed to have inherited all the looks and gifts of their mother, while the gifted daughter married into a secret world that was in the midst of a Civil War.

Unaware of the war, as her daughter didn't want to alarm her, they were unprepared for an attack...

If you will I have an idea, and perhaps a challenge, that you might try. Specifically a "Harry Potter" in book four challenge. It is common among fanfiction that Harry, or some other principle, with try to argue against his participation by various means. Including either no actual contract or alteration of the tasks in the tournament, but always asking for someone else to act. Perhaps the author in question will have him participate but alter how this done by using minimal effort, over powering him, etc. My challenge is to render the Tournament, and its contract, moot and entirely meaning...
