X-men, the X-Gene and various elements involved in that belong to Marvel Comics.
Buffy the Vampire Slayer and it's various characters belong to Joss Whedon. The Show itself was a Fox thing.
This is a piece of fanfiction that is not intended for profit of any kind, anyways, on with the show.
It had been a long night of explanations, recriminations and even a few accusations, but things were mostly sorted out between Buffy and her mother. Joyce certainly wasn't happy that her daughter had been keeping secrets, even if she wouldn't have believed it without a substantial amount of proof.
Xander's... additions as well as a few simple demonstrations of her daughter's advanced strength and dexterity went a long way towards convincing Joyce that her daughter wasn't crazy after all.
There were some concessions of course. Buffy wasn't allowed to patrol by herself, which in all honesty Buffy didn't mind now that she had backup in Xander. The teen had survived and healed something that probably would have killed her.
Another concession was that she had to accompany Xander to church on a weekly basis. Joyce felt that if her daughter was going to be fighting the forces of darkness on a regular basis, she needed to be reminded of the other side of the equation as well.
Aside from these concessions and that she'd have to cut back on training if her grades slipped the final concession was that the two teens were to help out in Joyce's gallery whenever there was a considerable amount of heavy lifting involved.
“Oh that's not right.” Willow said as she stared at the two teens who were playing an impromptu game of Frisbee.
The Frisbee in question was actually a 45 pound weight they'd appropriated from the school's free weight room for this very purpose. Both teens had sufficient strength to throw the weight, the real trick was to maintain their balance as they caught and threw the weight around.
“You're right.” Giles said from where he was sitting. “Could the two of you take that outside please?”
“Sorry.” Xander and Buffy said unison before heading out to the empty parking lot.
“So are you guys looking forward to the trip to the museum?” Willow asked the two teens when they were finished.
“Not so much, no.” Xander said with a bit of a shudder.
“Why not? I've seen the exhibit, it's quite nice.” Giles asked.
“The last field trip I went on I was possessed by the primal spirit of a Hyena and ate a pig. After that my mutation kicked in.” Xander said as he wiggled his fingers, claws extended. “I really don't want to see what this one can throw at us.”
“I think you're being a bit paranoid.” Giles said.
All three teens stared at Giles.
“I'll sign up as a chaperon then.” He said with a sigh.
“Thanks.” Xander said, looking relieved.
At the Museum....
“Get it off! Get it off!” Xander screamed as he tried to claw at the decrepit corpse clinging to his back.
He suddenly felt very tired and fell to his knees.
Buffy pulled the hair of the girl that used to be a mummy and managed to get her off of Xander who collapsed to the floor and began snoring quite loudly.
“He should be dead.” The mummy girl said aloud.
“You speak English?” Buffy asked her.
“I guess.” the girl said with a shrug.
“Was this feeding a one time thing?” Buffy asked her.
“ I don't think so.” The mummy girl said after a few moments.
“Then I'm sorry.” Buffy said to her.
“For what?” the girl asked.
“For this.” a male voice behind her said.
The Incan Mummy felt a tug on her neck before the world around her began to spin.
Giles and Buffy stared at the headless body as it began to mummify in front of them.
With a shaking hand, Giles put the sword back at in its display case.
“Field trips...” Giles began.
“Never again.” Buffy agreed.
Xander snored loudly from his position on the floor.
“Come on, let's get him back on the bus.” Buffy said to her Watcher.
“You'll do the lifting right? He's gained some more weight.” Giles asked her.
“Fine, you big baby.” Buffy said as she rolled her eyes.
“I'm not a baby, I just don't want to throw my back out again.” Giles said as they tried to get the slumbering teen off of the floor.
A week and a half later everyone was more than a little surprised by the apparent downturn of activity of the supernatural variety on the Hellmouth.
Buffy said something about it one night when she and Xander were on patrol and Xander just looked at her.
“You know you just screwed us right?” He asked her.
“What do you mean?” Buffy said.
“Have you heard about my friend Murphy?” Xander asked before looking off in one direction. “I smell blood. You had to say something didn't you?” He said before following his nose.
“What have you got?” Buffy asked him as Xander squatted down and picked something up.
“A bracelet. It's from the girl's preparatory school here in town.” Xander said as he held the bracelet up to his nose to get a better..taste of the scent. “She was very afraid when this fell off. Two, maybe three men were chasing her.”
“Can you track her?” Buffy asked, concerned.
“Yep.” Xander said as he began to jog at a moderate pace.
Shaking her head, Buffy stifled a laugh and followed him.
“A frat house.” Buffy said in confusion. “She's been taken to a frat house.”
“There's something...wrong with it.” Xander said.
“What?” Buffy asked him.
“I don't know, something's raising the hairs on the back of my neck. Something here is old, and wrong.”
“Let's go and see what's up.” Buffy said, walking towards the door.
“Woah there.” the large frat boy at the door said as the two teens walked up.
“What? I heard there was a party.” Buffy said.
“You can come in. The townie can't.” The meathead told her.
“I guess now is the time to use that thing Giles taught me from his rugby days.” Xander said with a sigh.
“Huh?” The frat guy said.
Xander head butted him and the older male dropped like a sack of potatoes.
“Subtle.” Buffy said with a snort.
Xander rubbed his forehead. “I need to practice that some more.”
“I'm sure there are loads of guys inside you can try that on.” Buffy assured him.
“Promise?” Xander pouted.
Xander looked around the room and sniffed the air.
“Do me a favor” he said into Buffy's ear.
“What's the favor?” Buffy asked him.
“Don't drink anything. The beer doesn't smell right.” Xander told her.
“Gotcha. You smell anything else?” Buffy wondered.
Xander paused and sniffed the air. “Yeah, and you're not gonna like it.”
“What?” Buffy said.
“Cordelia and Harmony are here.” He said with a depressed sigh.
“Super. Let's go find them.” Buffy said with an equally depressed tone in her voice.
“Now that is one ugly bastard.” Buffy said as she and Xander saw the half snake thing rise up out of the water.
“Dibs.” Xander called before leaping at it.
“What? No fair!” Buffy whined as Xander leaped up to fight the giant snake.
“Do me a favor and get those two airheads to shut up would you?” Xander yelled at her as he tried to wrestle with the supposed snake god.
Buffy broke Harmony and Cordelia's chains as the two teens continued screaming in terror while staring at Xander who had successfully managed to gouge out the snake being's eyes and and was working on trying to dig his claws into the demons tough hide.
“Are you still trying to kill it?” Buffy called up to him.
“Fine, I'll do it the easy way.” Xander said before snapping the creatures neck and he continued twisting the things head as it's body began convulsing.
“Took you long enough.” Buffy called.
“I didn't pack a short sword tonight.” Xander said before wrenching the thing's head off causing black blood to spill onto the floor. Xander tossed the head behind him before jumping over to Buffy and the girls who'd been lined up for sacrifice.
“Ladies.” Xander said with a nod. “I think it'd be best if we all left this little shindig a bit early tonight. It's pretty obvious these fellas here didn't invite you here with the best intentions in mind.”
“Yeah, let's do that.” Cordelia agreed while Harmony nodded frantically. The other girls who'd been brought here were murmuring agreements as well.
“They can be taught!” Buffy half crowed.
“No more older guys.” Cordelia promised mostly to herself.
“Agreed.” Harmony said.
“Where have you been?” Joyce asked her daughter as Buffy came in a half hour after her curfew.
“I had to crash a party.” Buffy told her mom as she took her jacket off.
“It was a frat party.” Buffy said as a way of explanation.
“You're not helping your case Buffy.” Joyce told her daughter.
“They were sacrificing a bunch of girls to a snake demon. I didn't drink anything. Xander said the beer was drugged.”
Joyce blinked. “Oh, that's okay then. I've made some cocoa, would you like some?”
“Do they have those little marshmallows?” Buffy asked her.
“I think I can scrounge some up.” Joyce told her daughter.
“Awesome.” Buffy enthused.
Principal Snyder made his way towards the student common area. “All right! Harris, Summers, Rosenburg, Chase and you, the one with the funny hair.” Snyder said as he pointed at the short teen by the soda machine.
The teen in question raised an eyebrow in response.
“I need you to be escorts for Sunnydale Elementary's trick or treating next week. Try and dress as a group.”
“What? I've got a party I'm supposed to go to. I can't be seen with these losers!” Cordelia said.
“Actually, Devon can't make it.” The short teen said quietly.
“What? Oh he is so dumped!” Cordelia huffed.
“Whatever. I've got a some coupons for a new costume shop in town. If you don't do this, Saturday detentions the rest of the year.” Snyder said before handing Buffy the coupons. “And no funny stuff.” Snyder said before storming off.
“Well there goes my quiet night of snorting Pixie Sticks.” Xander said.
Buffy and Willow laughed while the short teen raised his eyebrow again.
“So what's this costume shop called.?” Cordelia asked.
Buffy looked at the coupons. “Ethans.” Buffy told the others.
