Harry Potter • 2136 stories • Updated 20 Aug

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.

Challenge 3763: Faith goes Harry Hunting.
In Season 3 of Buffy the Mayor says he always keeps his campaign promises, what if one of those promises was to Voldemort, To hunt down and Kill Harry Potter, and He sends Faith to do the Job.

Could be set while Harry's at the Dursleys as the Wards protect from Evil Wizards but do they protect against muggles (they never stopped the Dursleys attacks)

OR

Could be Set after Harry killed Voldemort, with Harry more than capable of protecting himself.

Should ideally end up as a Faith/Harry pairing.

Should also include the Line (Faith about Harry)

Challenge 3735: A Helping Paw,
Ok possible a very insane crossover idea,

Willow and Tara had a pet kitten (around season 4 I think) but what if it wasn't really a Cat but was in fact Harry Potter Aurora 1st Class (in an Animagus form) sent by the Ministry of Magic to keep an Eye on the Hellmouth to make sure it stayed shut, so he has to help the Slayer and her friends to guard the Hellmouth but is not aloud to expose the Wizarding world to the Slayers group, so he hides during the day as Willow cat where he can keep a close watch on the slayers group, and by night he discreetly helps them to get rid of all the loca...

Challenge 3722: Harry Potter the Slayer
Just a strange Idea, what if Harry mother Lilly was a potential slayer and when she died to protect her son that potential was passed to him (same as he got some of Voldi skills) and When Willow activates all the Slayers Harry get activated to !!! (though no one realizes it as Harry already has the nightmare dreams and everyone already expects super!harry)

So the Scooby Gang have sent some one (ideally Faith or Dawn) looking for this new "Girl", and find Harry instead, (Slayer Powers could then be the Power Voldie know not)

Anyone willing to Try this?

Challenge 3703: Green eyes to Red
This is a Harry Potter Hellsing (anime/manga/ova) crossover.

Ultimately up to you how you plan it just some points that must be in it.


1. it starts either just before order of the phoenix or really early in that time period.

2. Seras Victoria must be his Sire.

3. The Pairing must be Harry/Seras.

4. Harry has definately got to be a vampire and you must show him having great difficulty adapting to the change.

5. Out of all his friends Hermione will stick by his side during his change and after...the others Ron Neville the weasleys etc ar...

Challenge 3686: Buffy in Azkaban
Buffy/Sirius

Post-Chosen, Buffy and the gang go to England to take over the Watcher's Council, where they work from an old castle (similar to the Season 8 comic, but not following that storyline).

Changing the timeline of Harry Potter (instead of Harry being close to Buffy's age, he's still a kid at the Dursleys, sleeping in his cupboard), Sirius has been in Azkaban for several years, but not enough to have changed significantly. Probably 3-6 years.

The Council gets wind of some strange activity in a small coastal town, and Buffy goes to investigate. She sees a Demen...

Challenge 3661: A Witch in the Buff(y)!
(BTVS/Harry Potter X-Over)

Buffy is not your average ordinary girl, she is a witch just like her grandmother and father before her and is in attendance at Hogwarts. During her fifth year at her beloved school, Buffy's parents divorce and her muggle mother returns to her hometown of Sunnydale, California. Unfortunately for Buffy it happens at almost the exact same time as she is called as the slayer. Surviving all the trials and tribulations of Hogwarts over the next two years, she is sent - by her father - to visit her mother and younger sister in America the summer vacation between s...

Challenge 3627: Through the Looking Glass (BtVS / HP, possibly others)
Harry (or one of his friends) discovers that the Mirror of Erised can show the world as it might be if things were different; for example, if there was no magical community as they know it. One of the worlds shown is another castle, very much like Hogwarts, in which a load of teenage girls seem to be learning to fight monsters. So whoever is looking starts to study their techniques, hoping to find something to use against Voldemort, and gets glimpses of stuff like Wicca magic, maybe starts to fall in love with someone glimpsed through the mirror.

The problems are first that it's entir...

Challenge 3407: The tragic beauty of a cosmic convergence

Challenge 3396: Buffy and Blondes
Buffy and Draco had a secret relationship.
Harry is Buffy's older brother.
Draco and Buffy had a bad breakup.
Maybe this is what leads her to Spike's and maybe even Angel's arms.
You decide how this plays out.. if in Hogwarts or Sunnydale. If the hp gang helps buffy out or the scoobies go to hogwarts.
Buffy's secret love and older brother is exactly that. a secret past that the scoobies don't know about including dawn.
HAVE FUN!

Challenge 3382: The Watcher's Witch
Crossover fic, taking place in England, in which either Giles or Xander is romantically involved with a female from the Potter universe. (Perferably Hermione, Ginny or Tonks.)

Their presence in England is to be explained by their employment with the Council (and the Council's existence is not a secret from the wizard world, though its purpose may be, or it may be assumed that one or both is only a legend).
