A/N: Buffy the Vampire Slayer belongs to WB ans Star Trek TNG belongs to CBS... I do not own these no matter how many quarters I throw in the wishing well.

Past Sins

1

(June 2013- Afghanistan)

The heat was oppressive; it beat mercilessly down on her back as she stood on a rock taking in the desert surroundings, trying to blink sand out of her eye. This was not the first time Buffy Summers cursed her lot in life. For nearly seventeen years she had been hunting down the things of which nightmares were made, putting an end to the supernatural threats to mankind. This, however, was a new type of hell. The only reason she would ever subject herself to this kind of punishment was the fact that her latest slay was completely out of the ordinary. He wasn't a demon... exactly.

The slayer remembered how hard he had thrown her into that wall in Paris. It was strength that rivaled her own, and if it hadn't been for Willow's quick thinking she might have actually lost. Even though the red-haired witch had managed to slow him down just long enough for Buffy to get the upper hand, it was still one of her tougher fights.

"Buffy, have you found anything yet?" sounded Xander's voice in her ear.

Buffy rolled her eyes and sighed as she tapped a button built into her watch. "Sand and heat, Xander, sand and heat."

Xander Harris wiped the sweat off of his brow as he stared at the computer screen with his one good eye. The temporary headquarters A/C still wasn't working properly after the week and a half they had been there. Pulling up the satellite charts Willow had managed to swipe from the feds, he watched the energy output.

"You're within five hundred meters of the installation Buff; maybe it's underground." He could hear the frustration in her voice when she responded.

"I guess I'll start digging then," she said sarcastically.

Buffy closed the channel and continued her trek through the unforgiving wasteland.

"I can't believe they're engineering humans with demon DNA," she muttered to herself. "Didn't Adam teach them anything?"

She remembered the shock when she learned that the happenings that had occurred in Paris were caused by a hybrid who was rallying both humans and demons to form an army. Once the deed was done Giles decided to let the Watchers examine the body, and what they had found had cut Buffy to the core: apparently the Initiative wasn't the only group to practice experimentation on demons. They found hidden records for a "Project Chrysalis" dating back to the sixties, and with their projects came the Eugenics Wars that had been fought in secret during the mid-nineties.

Over the next few months they had run across four others engineered just like the first, and had learned that the project that created them was still operating, despite genetic engineering having become illegal across the globe. However, this was different; instead of trying to make perfect humans, they were bastardizing the species by crossing them with demons. It made Buffy's head hurt to know that there was an entire facility of Professor Walsh's.

Buffy continued searching for some kind of hidden door, but she had to be honest with herself. A mission like this was more suited for Riley or even Xander, but this was something only she could do. Faith, Dawn, and Xander were busy with the other slayers in the area, and Riley was who-knew-where with Sam looking for who-knew-whom. Willow was still in Scotland... How Buffy wished to have her best friend by her side right now.

She made her way up a small, steep hill, wincing in pain as the sun-baked rocks burnt her hands. "I'm thirty-two years old," she thought to herself. "I should be taking kids to soccer games in my minivan, not tracking down another evil that could destroy the world." She pulled herself up the last bit of rock and took another look around the barren land with her binoculars.

Scanning the horizon, she caught sight of a cave entrance. At first glance she almost dismissed it as just another hole in which desert critters scurried around, but in the sand she was able to make out faint tire tracks. For the first time in days she felt a sense of accomplishment and she activated the homing beacon built into her watch."Bingo guys, I think I found it."

The Slayer knew backup was on its way, but she couldn't resist trying to get a closer look. She crept down the rocks and up to the mouth of the caves. The tracks led to the back of the cave where there was just a wall to greet her. For a brief moment she felt like she had simply wasted her time. As she turned around, she felt an unnatural shift under her feet. Kneeling down, Buffy dusted the sand away, revealing what appeared to be a weight sensor. She knew she should wait for the rest of her team, but she punched the sensor anyway. Under the force of her slayer strength the sensor registered a vehicle and the ground beneath her started to move.

It only took a moment for Buffy to realize that she was standing on an elevator, and another thought quickly crossed her mind: she had no idea what kind of people were here, nor how many there were. As the lift descended she reached back for the dagger she kept in her pack. She crouched as the lift cleared the stone, revealing a large cavern with what looked to be an entire military base built into it. She noticed people in the cavern stopping and staring at her as the large lift came down with the small girl on it.

Suddenly an alarm went off and she saw six officers coming towards her. Instantly she fell into a warriors' stance, but when she saw the faint orange hue in their eyes indicative of hybridizing, she relaxed and raised her hands. She knew she couldn't beat them by herself, and to even try was foolish.

A helicopter tore through the blazing air as a strike time was looking for its missing slayer.

"Last contact was four hours ago in this spot," Xander said from the pilot's seat.

Dawn sat next to him surveying the desert. "I wonder if she was spotted and driven off," she said as she peered through a pair of binoculars.

"More likely she went in without us," Xander replied with a grim edge in his voice.

Faith scoffed from the back seat, "Sounds like B. Take the fun and glory before we even touch ground." As they made one last pass, Dawn spotted a large cave opening, making sure to point it out to the one-eyed pilot.

Buffy groaned as consciousness began to return to her. The last thing she remembered was one hell of a shock. She quietly cursed her stupidity as she tried to stand up, only to find she was strapped to a chair.

"Wonderful," she muttered sarcastically as she tried to clear the fog from her mind.

"You're awake," came a voice from behind her. From what she could tell it was a male voice with an Indian accent. "I've got to say, I didn't expect you to be foolish enough to come here by yourself." Buffy tried to look behind her to see who was speaking, but was unable to turn her head that far.

"Who are you?" she asked through gritted teeth. She heard a slight chuckle.

"Why would i tell you who I am if I've taken steps to ensure you can't see me?"

Buffy had to admit to herself that he had a point, so she decided to focus on breaking her bonds.

"What will you do with me?" Silence sliced at her for a moment before she heard him draw a breath.

"That depends on you. The work we do here is invaluable in furthering the human condition." The Slayer rolled her eyes at the statement.

"What does that have to do with me?" Again she could feel him pondering what to say next. Probably trying to avoid giving too much away, she thought when he spoke up.

"Your genetic markers are really quite interesting. They mirror what we're trying to accomplish, but yours seem to be natural. Tell me, what abilities do you posses?"

An instant later she felt the straps give. With a quick thrust she was free, on her feet, and facing her captor. Buffy stifled a giggle to see such a small man.

"There's one," she said smugly before bolting for the door. Just as she was reaching for the handle the door swung open, knocking her off her feet. There, standing in the doorway, was the largest hybrid she had seen yet; however, this one had the telltale facial features of a vampire.

"Really... You should know that adding vampire to the mix is a terrible idea," she said before scrambling to her chair. With a quick movement she smashed the chair against the seven-foot hybrid and with a twirl, jammed the broken chair leg into its chest.

"Missed," it said with a grim smile. "Thicker bones, little slayer." Buffy groaned at the creature and, with a jump kick, sent the makeshift stake into the hybrid's heart, causing him to hit the floor convulsing.

As the creature slowly turned to dust behind her, she turned back to the white-coated man in the room. He was looking at her with elation in his eyes.

"I had heard rumors of the power of the slayer, but I've never actually seen it. Your blood will be the key in creating a more perfect human." Buffy was appalled at the thought of her genetic material being used to create such monstrosities.

"I kind of need my blood," she said. "And I'm not really into sharing," she added with a touch of sarcasm.

The Indian scientist paced. "We already have it. We took it while you were sleeping." Buffy suppressed the urge to rip the man's spine out though his nose.

"Then I'll find it and destroy it." She took a step towards him as the cavern above them shuddered and pieces of rock came falling down. "Looks like my ride's here," she said as the scientist made a mad dash for the door. Buffy attempted to catch him, but another shudder knocked her off balance.

She chased him out the door, but he was already out of sight. What she did see was Faith and six other slayers fighting the hybrids. Deciding the scientist was gone, she ran over to help her fellow slayers. She knew they could search for him after taking care of the grunts. Faith shouted as she snapped the neck of one of the hybrids. She had taken two out already when she spotted Buffy running towards them.

"B, over here!" she shouted and waved. Buffy took up a spot beside the slayer and went to town pummeling the hybrids. After several minutes the flow of creatures stopped as the cavern was once again rocked by shaking; this time, however, it felt like it was coming from inside.

"Guys," Xander's panicked voice crackled over the com link, "They're launching something." Xander and Dawn sat in the helicopter watching as a rocket exited the underground base aimed high towards the sky.

"What are they doing?" Dawn asked as she stared awestruck.

"I don't know, babe," Xander answered. "I just hope it's not a missile." They continued staring until they caught sight of eight slayers running towards the copter. Buffy was the first to make it to the craft and jumped right in.

"The base is going to blow," she said while trying to catch her breath. Xander didn't need to be told twice and as soon as the team was aboard, he fired up the engines and lifted off as the first explosions tore through the ground. They returned to their makeshift base to catch a larger chopper to return them to the headquarters.

Buffy woke up as the chopper touched down at Slayer HQ. The crew disembarked while Xander, Dawn, Buffy, and Faith made their way to the control room where Giles and Willow were working on what happened.

"Thanks for the save guys," Buffy said as she entered the room. Willow smiled and waved at her best friend as she pulled a blueprint off the printer.

"Boy, this was hard to come by," she said as she spread it out on the table.

"Uh, Will, why are we looking at a submarine?" Buffy asked in confusion, looking at the blueprint in front of her. Willow chuckled a little.

"It's not a submarine Buff, it's a space ship." Xander walked over and took a look.

"It looks like a submarine, Will." Willow scowled at him and went over the blueprints.

"It's a DY-100 class ship. It was supposed to revolutionize space travel, but people didn't feel comfortable flying through the stars on a 'nuclear powered tin can.'" Giles perked up and walked over.

"Yes, I've heard of them. Only a few were built. The only one known to have flown was reportedly stolen by the terrorists that followed Kahn Noonian Singh."

Buffy smiled at him. "Always with the knowledge. That's why we love you, Giles." Xander sat playing with his eye patch.

"So if they escaped to space, how do we stop them?" he asked. Willow pointed to a spot in the middle of the vessel.

"It's a sleeper ship, so that means they'll be away for a long time," she explained. Buffy plopped down into a chair.

"But come on, how long can a ship like that really last?" she said skeptically. Giles looked down closer at the blueprints and sighed.

"With a nuclear reactor and the entire crew asleep, I would estimate that they could last quite a long while. Possibly a couple of centuries," he said. Buffy threw her head back in frustration.

"So not only are these freaks are creating human and demon hybrids, but now they have the blood of a slayer to play with," she said. Everyone at the table looked silently at Buffy, who shrank back in her chair. "What? They tazed me and took it while I was unconscious." Xander pressed both hands on the table.

"And tell me, if you had waited for backup like we told you to, could this situation have been avoided?" he asked. Buffy sank a little farther into her chair. When she spoke, it was quiet.

"Maybe."

Giles rubbed the bridge of his nose. "At this point it doesn't matter how they got it, just that they got it. That means that when they return we need to be ready." Willow looked away from Buffy.

"Um Giles, there's no more magic. That means no more slayers to deal with the sitch." Giles smiled lightly.

"Yes Willow. As usual, your power of observation amazes us all, but I think there may well in fact be a solution." At Giles' mention of a solution Buffy perked up.

"Send a missile after them?" she asked hopefully.

"No, not quite," he said with a hint of smugness. "We'll do something they'll never expect. We'll send the slayer after them." Buffy looked at the watcher like he had grown a second head.

"I'll be lucky to make it to forty, let alone two hundred." Suddenly, a familiar British accent came from behind her.

"He doesn't mean just sit and wait, Love. I knew you had your moments, but I thought you could add two and two better than that." Everyone turned to see Spike and Angel making their way into the room. "Luckily, I've managed to acquire what you need in order to do this." Spike motioned as four slayers pulled a cart in with what looked like three mechanical coffins. Giles straightened up.

"These were taken from a facility experimenting with cryogenic technology. When I heard the report, I thought we might need them." Xander looked the capsules over.

"And you just happened to have them here, now, and ready for us. Color me concerned, but that is rather convenient." Spike scoffed and slapped Angel on the shoulder.

"Look at this guy, mate. We brought them from L.A. Charter flights are faster than your heli."

Xander gave him a fake smile. "Leave it to our vamp buddies to bail us out."

"Enough!" Giles shouted. "I called Angel as soon as I thought we might have an issue. Once he got ahold of Spike they were here an hour before you." Suddenly Buffy spun back to face Giles.

"You're going to freeze me!"

Giles nodded slightly. "I think we need to have a team on stand-by in case an issue comes up in which a slayer or two is needed. Therefore Buffy, Willow, and Faith are, in my opinion, to be the perfect team."

Willow Rosenberg's eyes went as wide as saucers. "Wh... What did I do? I didn't get my blood stolen."

"Of course you don't have to go," Giles said, rolling his eyes. "I just thought you would make the best advisor when the time came."

Willow relaxed. "Oh... Well in that case, just call me Advisor Willow." Giles looked around the room.

"Buffy?"

"I guess I should, but Faith?" she grunted.

(Two weeks later)

Buffy, Willow, and Faith all stood in front of the stasis tubes. Willow was beginning to shake a bit and Buffy put her arm over her shoulder to comfort her.

"Hey Will," she said calmly, "are you ready for your nap?" Willow shook her head and looked and Dawn, who had obviously been crying.

"Do we have to leave?" she asked quietly.

Angel walked up behind her and spoke. "You're not leaving. You're just sleeping." Buffy gave Angel a hug and walked up to Spike.

"So Spike, you got elected to be our guardian?"

Spike smiled at the slayer. "Don't get your knickers in a twist, Love. It was this or possibly getting slain by an angry librarian." Buffy chuckled a bit and gave him a kiss on the cheek.

"I'm sorry I couldn't be what you wanted me to be."

Faith looked on with a smirk. "Come on B, give him a ride before the road." Buffy rolled her eyes and punched Spike in the arm when she saw him smiling at the thought.

After a few more goodbyes the trio stepped into their tubes and watched as the tubes were sealed. Willow jumped at the hiss of the anesthetic gas as it flooded the tube. The last thing she remembered before drifting into unconsciousness was taking a deep breath to scream.

Once the process was complete, Giles, Angel, Spike, and Xander looked upon their frozen friends.

"Well gentlemen," Giles said simply, "they'll be here if we need them."
