Xander is a mutant, however he was never actually stressed enough for it to fully activate. That is until the Fertilizer Bomb fails to kill the Mayor. When one of his girls is injured/killed Xander's power finally erupts: The Firestorm is born. What happens after he defeats the mayor is up to you.

Firestorm (based on the original Nuclear Man abilities) has a number of powers based around Matter and Energy Control

Known Powers:
-Super human Strength and Endurance: Can lift 10 tons and operated for a weeks without any sleep.
-Phasing: Firestorm can disperse his own mo...

Xander is a Pre-Immortal.
He is found by Kronos, before or during Season 1, who decided to create a Protégé to help spread mayhem across the USA.
What effect would being raised by War have on Xander?

No Male/Male pairings

YAHF
Xander dresses as one of the C'tan (Necron Gods, Warhammer 40k), and unleashes a horror upon the universe never before seen as he is unlikely to retain his identity (but it is not impossible).
Possible X-over with Mass Effect/Stargate later on if the C'tan decides to explore the new universe it has found itself in. (Wreaking havoc upon the citadel races/the Goa'uld and humans alike).

During Halloween have at least three Buffyverse females dress up as at least three species of Monster Girls. This can be a Multi-crossover if you wish and you don't have to but I would prefer at least three females to be paired with the same man.

P.S. check out monstergirlencyclopedia.wikia.com for species list

There are not enough Spider-Man crossovers here. I challenge you authors of Twisting the Hellmouth to write a Spider-Man crossover with:

>Xander having Venom
>Do Not Make It A YAHF! I want you to try using a different episode or even have the event (Xander gaining Venom) happen before or after the show begins or ends.
>You can't have the story happen in the Marvel Universe. Try using different Universes instead. Like Spider-Man and Stargate, or just Stargate with Venom in the story, or the DC Universe, etc, etc. You can use other Marvel Universes in the story like X-M...

We have seen lots of Halloween Stories where Xander changes his mind or convices all of them to change their minds on their costumes....I would love to see one where Willow changes her mind, without having to be convinced to or having the idea that all of them has to.

Must Have:
1. Willow of BTVS choosing a different costume without having to be convinced into it.
2. Willow keeping some or all of the powers, knowledge, etc. of the person she dressed up as.

I've read and loved many of the Ship of the line stories.

the only problem with them is that there are only a handful of (modern) sci Fi shows set in the 90's (Stargate, 2001 a space Odyssey, Anime like Tenchi Muyo, etc.)

I've also recently read the what if the other guy got the Scoobies memories challenge.

Which inspired this little plot bunny.

1 During Halloween (or anywhere else you can think to put it in) a space ship is created.

2 The ship should be a combination of multiple realities. (either the "captain" dressed in a costume that had parts f...

Now that Irrational Games has said their bit and left, those of us feeling they were a bit too cute in trying to wrap up Infinite and make it the prequel to Bioshock have our chance.

If you want to cross someone over, that's fine, but for the larger part this should be about working the DeWitts out of the doom they were each saddled with.

DO:
1) Manage to save Booker and/or Elizabeth, any number of deaths or close calls being allowable given the setting.
2) Give an internal structure or framework to the multiple worlds concept.
3) Include Lutece moments. Pianos no...
