Harry Potter • 2354 stories • Updated 18 Mar

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.

Set post "Chosen" for BtVS, and sometime just before or during The Half Blood Prince for HP. The Council is rebuilding in London, and Giles is renewing old Council contacts, including those he's just discovered in the wizarding world. In a PR move to assure the people and ministry that she's no longer a danger, Giles encourages Willow and the coven that helped her to do an interview with The Quibbler (even Giles knows The Prophet is a bunch of hooey).

Dumbledore reads the interview and notices that the first spell Willow actually cast was a soul restoration spell on the infamous Ang...

Weasleys' Wizard Wheezes has recently obtained a very interesting product; chocolate bars that make the eater behave like a teenager.

You make this as funny or disturbing as you want, and the change doesn't have to be purely mental.

(Adding a certain group of enchanted Halloween costumes may increase the fun, or horror, if your into that kind of thing)

The Shadow Men used magic to create the Slayer, and to prevent the Slayer line from being tampered with. For the sake of this challenge, assume only someone way stronger than all the Shadow Men combined (like Willow) could tamper with the Slayer line.

Now, the challenge: The monks that created Dawn started too late. Glory found them, making all but one use as much magic as possible to keep her away while the remaining monk created Dawn and put the Key in her. Only, alone, the one monk didn't have enough power to create Dawn from Buffy (since the magic the Shadow Men used saw it as ...

Hopefully someone wants to write this:

A field trip to the Hellmouth leads the Golden Trio to meeting the Scoobies. Two of them (one from each group) find out that they are soulmates. They decide to take it slow (no immediately falling in love, please), and mail (owl) each other over the next few years.

Sometime Post Chosen, the member of the Golden Trio breaks it off, claiming to be in love with someone else. Naturally, the Scooby in question finds this to be suspicious and, possibly with the rest of the Scoobies and Mini-Slayers in tow, heads off to Hogwarts to find that...

Harry Potter/BTVS Crossover.

Challenge Summary:

The events on the Hellmouth (which events are up to you) have attracted the attention of the Ministry of Magic. Desperate for information, they kidnap an unsuspecting native of Sunnydale for a little while and send in a everyone's favourite doppelganger as an undercover agent to find out what's going on.

Requirements:

1. Tonks must take over the identity of a human member of the supporting cast - of either sex - not a main cast member.
2. No BtVS characters or entities have any prior knowledge of the wizarding world
3. No need to try and match time lines between HP an...

Okay, here is my idea.

Doyle is the PtB's pawn, right? And so is Cordy, right? Well, they were sent to help Angel and died doing just that, but they died too young for the Powers. They don't want them to go to waste, but they can't excatly go back to Angel, can they? They did their jobs with Angel and now it's the Boy-Who-Lived's turn to have helpers who will truely help him.

Doyle waits up there in Heaven, or where ever the PtB's are, for Cordy. When Cordy finally dies in the hospital she is given a second chance at life, love, and family. Doyle had already made the choice...

Xander in an HP crossover. You can decide when to put him but my idea? Everything plays out just the same in BtVS world or maybe a bit more gruesome? At the 'end' Xander wakes up screaming. He has a latent seer gene (parents are squibs or descended from a squib years ago - none have shown potential. Maybe that kicked out ancestor moved to the Hellmouth in the hopes that his line would pick up some of the free floating power, thus making them magical again?) That gene kicks in, in combination with the Hellmouth (sentient and connected to itself - past, present, and future - not wanting to go ka...

We've all read the stories about Harry Potter being raised by someone other than the Durseys. This challenge is different. I don't want Harry raised by anyone other than the Durseys.
Instead... Sirius Black, the imprisoned godfather we meet and love in book three does not make an appearance. The criminal relative of Harry Potter who escapes prison and decides to meddle is Ethan Rayne.
Or Giles, whose parole was strictly under Council guideance and he finally decides enough is enough when he sees Wormtail's rat form in the paper, on the shoulder of a good friend of his godson.

Ron isn't the youngest of the Weasley sons, no, no -- nothing so pedestrian as waving a stick and saying a few words! He's the (adopted) younger brother of either of our favorite Sunnydalean redheads -- Oz or Willow, take your pick.

When he's eleven years old, Ron gets letters from both an American school of magic or Hogwarts, but declines to go, thinking it's a joke. Now, given Dumbledore not being the lackadaisical sort, he can't understand a Weasley (or not, in this case) attending any school other than Hogwarts.

Given Ron's different upbringing, of course, his persona...

There's loads of HP crossovers where someone from the Buffyverse drops into Hogwarts.

This is a bit different, have a girl from BtVS or AtS drop into the school in 1945.
Dumbledore's just a professor, more or less young. Has color in his beard.

Tom Riddle is a seventh year Head Boy. Has just started dabbling in the Dark Arts, but still has some humanity left.
Dangerous as hell though.

Have the girl sorted into Slytherin.
Of course there should be tension with Riddle, bonus points if the girl can fluster the future dark lord with sexual innuendo.
It ...

The myth of the Vampire Slayer goes as follows: "In every generation there is a Chosen One. She alone will stand against the vampires, the demons, and the forces of darkness. She is the Slayer."

Analogue to the Slayer legend, there is a Hunter myth: "In every generation there is a Chosen One. He alone will stand against the warlocks, the mages and the forces of darkness. He is the Hunter."

So at any moment in time, there is a Vampire Slayer and a Warlock Hunter in existence, both overseen by 'separate' branches of the Watchers Council.

When Buffy becomes a Slayer, Ha...

Desperate to give Harry as much protection as possible, Dumbledore, Upon finding out about the Halloween Soldier possession, hires Xander as a Muggle Weaponry Training professor.

It can be any type of het or slash pairing or a gen fic.

Bonus points if Draco, Snape and or Lucius, get hit by a learning curve-ball, maybe even a bit of a fright, IE seeing a bullet shred through a shielding charm most spells wouldn't penetrate.

So here's the challenge, write a twist on Harry and Buffy being related. there are a ton of Buffy as Harry's twin/sister/cousin but i would love to see Harry ( or one of the younger HP characters) as Buffy's father. I don't care what season or book you want to set it in or who you want to make Buffy's mom. I only ask that there is no Ron/Hermione, that ship makes me want to hurt things.

i posted this challenge the other day but it vanished so I'm trying again. sorry if you have already read this!

love!

Ok, authors here are the details for this challenge.

1. Xander is Snape's son.
2. Severus never knew he had a son until the boys adoptive parents died and he is notified by the ministry.
3. Not only does he come to the attention of his father but also to the dark lord.

Well thats everything the story must have. Anything else I will leave to the author who decides to take up this challenge. Thank you for reading this challenge and I can't wait to see what it becomes.
