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.

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...

After Xander dresses as his hero Captain America for Halloween, one important thing sticks around- his memory of where the plane went down. With the help of a locator spell and a trip to the Arctic Xander brings Steve Rogers out of the ice more than a decade before Tony Stark becomes Iron Man. With nowhere else to go Steve returns to Sunnydale to adjust to the modern world and help the Scoobies fight demons.

-SHIELD cannot be aware Captain America is free until after Iron Man 1 occurs.
-Steve will remember the events of Halloween
-Can take place after season 2, when Buffy i...

We've all seen the typical Xander stories: Xander gets powers via Halloween, Xander has a different family, Xander joins an organization, Xander leaves the Scoobies, et cetera.

However, there are no stories in which Xander is an assassin of the Red Room.
I have decided to rectify that mistake.

When Xander is five, he is kidnapped and by an organization calling themselves the "Red Room", and trained into being an assassin. Sent to Sunnydale nine years later to hunt down a traitor, he vanishes off the map and is presumed Missing In Action. Then, just after Buffy defeat...

This would still let him have soldier style memories with better sword skills while not powering him up too much.
If you wanted to with a little help from the Hyena it would allow for crossovers with more versatility giving even what Wade had a boost. Though you would have to stick to Wade before the experiments.
It would even let you put him into the main Marvel Universe without too much adaptation.
Just thought it would be something I haven't read about yet but would fit into any Xander-centric story quite well.
Hope I get the chance to read one that you guys could come up wi...

Tony Stark, Nathan Stark & Xander are all at least half brothers, with Nathan and Tony having known each other previously.

Xander runs away from home as a teenager{14-17(due to abuse, backstabbing, injury...all of the above...)} and runs into Tony, ends up saving his life, which eventually leads to them finding out the family connection.

Tony and Nathan join together to help and get to know Xander, ensuring he gets extensive, effective & excellent Healing, Therapy, Tutoring and Self Defence Training{in case he gets kidnapped}

Slowly they each form a strong an...

Simple idea:
The Avengers have left for a life or death mission in deep space but unwilling to leave Earth unprotected Captain America has appointed Spider Man the new leader of an earth based Avengers. The first stumbling block Spider Man faces is that the Avengers leaving for space have bolstered their ranks with a bunch of earth's super hero population to face this space based foe, which means, Spider Man's got to pick and choose his team from third string super heroes. And from there things only get harder as his team must then face of against Avenger's foes combined with Spider Man'...

YAHF with a twist.

Rather than going as a regular soldier for Halloween, Xander decides to dress as the one eyed leader of S.H.I.E.L.D.

For some reason or another, the Halloween spell screws up and instead of turning into Nick Fury, Xander is transformed into a mix of Nick Fury and the one eyed Xander from the future. Once the spell ends, he is left with the memories and skills of both characters.

Now, what would a Xander with knowledge of the coming future as well as the skills, dedication and experience of a spymaster (a highly paranoid and duty bound one at that) ...

This is mostly for the Agents of Shield TV series that plays a companion to the Marvel Movies.
So here are the constraints
-Xander is added onto Coulson's team
-He plays the role of the supernatural consultant(of sorts)
-Marvel-verse is not necessarily the Buffy-verse
-Xander remains relatively human, no massive power boosts that throw him into the super hero zone
-This is a post or mid- Africa Xander, or at least Caleb has removed his eye
-Pirate jokes are made and possibly references to the similarities of Fury and Xander(Eye patch-wise at least)

hey, you try coming up with a suitable pun for the challenge (to use as your story title, duh.)

Anyway: Put Simply: Marvel Cinematic Universe crossover, wherein Xander takes the place of Tony Stark (Or other character) including all the memories of said person up to the point wherein he's placed.

How or why up to you (a canon event twisted for it, or not.)

See my own response for an example ficlet.

Xander is Agent Coulson.
Willow feels/hears about, Loki stabbing him, goes Darth Rosenberg.
Finds Loki at Stark tower, rips enough magic out of him to heal Coulson/Xander.

Back story: Xander growled under his breath as he and ?, the last two patrons in the store, both glared at the owner, one Ethan Rayne – Snyder, in his infinite troll-dom, had dropped trick-or-treating duty on Buffy, Willow and himself, but they had also been told that a adult would be accompanying them. What made it worse, though, was the fact that when he had gone to get a plastic gun to fit with his fatigues, some brat got the last one and he was out a Soldier Guy costume.

Sadly, the smarmy shop owner, Ethan, had only two costumes left, and they were a paired set. “Do not trifle...

I know there are quite a number of Halloween fic’s where one of the main characters dresses as a specific Mutant (Marvel Comics) and they retain the powers of the Mutant in question. While I don’t claim to be an expert in the comics in question, I’ve never really understood how they could retain the same powers (unless they permanently change into the character - genetics and all) after the spell ends.

Therefore, I propose that the effects of Halloween merely operate to provide the character(s) with the X-gene. Thus leaving the specific powers they are to develop to their own ge...
