Is slaying in two dimensions easier or harder than in three? Do Acme make stakes? And how do you kill characters that can withstand dismemberment, frying pans to the face, being flattened by steam rollers and blown up by fizzing sticks of dynamite on a regular basis? These are just some of the questions you probably won't find answers to in the Twisting the Hellmouth collection of cartoon crossover fanfics.

We've classic Disney and Looney Tunes, as well as more modern fare such as Gargoyles and of course no cartoons section would be complete without The Simpsons.

A Crossover of BTVS/Biker Mice From Mars. I would love to see this. You may use either the old version or the newer version.

Willow and Xander, being bone tired of all the fighting and the many expectations of them, leave on a road trip together after the collapse of Sunnydale, they end up meeting the Biker Mice and....??

Must Have:
1. Willow and Xander of BTVS.
2. Throttle, Vinnie and Modo.
3. Willow still having her Witch Powers, but also being a good Ass Kicker.
4. Xander being a good Ass Kicker, whether or not his eye is gone is up to you. There has to be ...

When sent away for safety by those who love them most, Dawn and Connor each end up in the Land of Ooo.

Finn and Jake, however, are not the first people or citizens of the Candy Kingdom they encounter, however. Funnily enough, particularly since the Ice King has that penchant for kidnapping while in search of a wife, Dawn ends up in Marceline's house -- the Ice King wouldn't dare hurt her there, after all.

Connor, of course, instead ends up in the company of Princess Bubblegum -- something that certainly makes Finn jealous if Ricardio the Heart Guy (also thanks to Ice King, o...

Here is a crazy challenge for you all.

What would it be like if the characters and events from the BtVS series took place in the Duck Tales/Darkwing Duck/Tale Spin universe?

What will the characters look like? How will the events of the Buffy series affect the other series and vice versa?

I was looking at the Scooby Doo stories and I was disappointed at how few there are. The gang constantly use Scooby references so I would assume that more people would try to incorporate Scooby into their stories. My challenge is kind of simple with only 3 basic "rules".

1. One or more of the Buffy gang dresses up as a member of the Scooby gang. (Preferably Xander)

2. They either buy a toy Scooby or his collar and put it on a toy or real dog. Bottom line is a member of the Doo family (Scrappy or Scooby) joins the Sunnydale crew. This means that they stick around after the spe...

Another Halloween Genderbender fic request.

This is mostly because I see a disturbing lack of Powerpuff Girls crossovers (which actually has a whole lot more potential than you'd expect), where Xander dresses as a Powerpuff Girl on a dare or lost a bet.

Not original, I know, but I thought, why not, since it has almost no action.

Anyway, I thought about making Xander Bubbles, or even Blossom (though Buttercup would be totally hilarious).

There are no age requirements for which outfit he picks, whether it's the kindergarten version, or the Powerpuff Girls Z ve...

The Powers that be should have known better. They really should have. You do not steal a child from one reality to have it grow up to full fill responsibilities in another. Not when his parents are still alive and kicking. Especially not these parents.

Now you have Eris and Hoss Delgado coming to Sunnydale looking for their little boy. A little boy who is all grown up named Alexander L. Harris.

Yes this idea came to me and well it does explain all of the chaos and his hatred of evil quite nicely. I leave it open to you if you want other fandoms mixed in. But the basis is ...

A Yet Another Halloween Challenge

Xander is ordered by Snyder to coordinate his costume with his youth group which turns out to be Dawn and four of her friends who decide to go as the Planeteers forcing Xander to dress up as Captain Planet.

I would like for everything to be retain including Xander being Captain Planet only being let out when the Planeteers let their powers combine. Maybe have Aura dress up as Gaia :)

And maybe a cross with Marvel.

Quite a few fics have used Willow as Gaia's chosen avatar, but they all seem to lack any real work ethic. It's all power no responsibility. I say we balance that out by giving her an actual job!

1. Willow is regularly summoned by a group of teens wielding artifacts that allow them to manipulate the elements. These ecoterrorists don't take no for an answer when faced with corporations that seem to consider polluting the environment to be their main goal, rather than an unfortunate side effect. Willow's job, when summoned by them combining their talismans, is to try and accomplish the t...

I was writing another story and I suddenly had a flash of inspiration to mention the Gummi Bears. After which, I felt like reading a Gummi Bear story. Alas, none were to be found on TTH. So, I am posting this very simple challenge to everyone to write a Gummi Bear story.

Rules:

-You can't call them Gummy Bears (with a 'y')
-Not YAHF
-No Slash. In fact, this is a kid's show. Try to keep it PG.
-I think a Scoobies go to Gummi Glen will work better than the other way around, but seeing Princess Cala in modern America could be interesting too.
-Have Fun!

As you can probably guess from the challenge name, this is for a Zuko/Buffy pairing. Now if they meet at some point during the series (when he's trying to find the avatar, his 'fugitive'/refugee time, or his travels with Aang and co., etc.) or after their journey is completed (though I'd like it if they met during the journey, at some point), I'll leave it to you to decide. Along with the fact if Buffy is a fire-bender or not. Though I'd like it if she kept her 'Slayer abilities'.

The time for Buffy-universe: After "The Gift" (meaning Buffy got de-aged a bit). A possible loss of memor...

YAHF. Xander dresses as a barbarian hero for Halloween, trying to be Conan, but instead for the night he becomes 'Dave, the Barbarian'.

Afterwards, he retains Dave's herculean strength, as well as bringing his enchanted sword, Lula, into reality... but also becomes a complete and total wuss who's first instinct to danger is to run away and hide rather than fight.

Bonus: After the change, Xander argues with the Narrator about whatever direction the story happens to take.

Bonus 2: Buffy basically gains Fang's mentality that, since Xander is easily strong enough to smas...

Xander "dressed" as actor Jackie Chan buying a stupid mask. What he did not expect, was that he became an archeologist Jackie Chan instead. Also, he did not expect powers and creatures from the show to make their way into reality due to Ethan's unfortunate choice of toys and props. Or for them to stay there, tryng to bring on their own mark of the Apocalipse. Still, at least he kept his possessors skills. Probably due to kicking statue of Janus to the ground himself.
Though the most disturbing moment was appearance of "Uncle" - demoted due to his part in Ethan's scheme Janus - and a cute ...
