First Teen Wolf fic. I own nothing except my OC's.

Stiles Stilinski had made it through the first day of junior year without being tardy to a single class. He hadn't fallen asleep in any of the classes either. And he also had heard nothing of any supernatural occurrences bothering the town of Beacon Hills. Overall, he felt like the first day back was a success.
"Stiles! Get over here!" Stiles heard his best friend, Scott McCall yell at him from down the hall. He looked over and saw Scott standing with Isaac Lahey, Erica Reyes, and Boyd. Groaning, Stiles walked over to them. He knew this was going to be bad news. He could tell from the looks on their faces.
"Derek wants us to meet him at his place," Scott explained.
"Why?" Stiles whined.
"Something's happened," Scott said.
"Can you clarify?" Stiles rolled his eyes. "Because in your guys's world, 'something' could literally mean anything."
"An omega is in town," Erica snapped.
"Is he nice?" Stiles asked.
"Well, considering Derek needs us all to confront him, I'm gonna guess no," Scott said.
"Alright, well, do we need to go now?" Stiles asked.
"What, you got somewhere you need to be?" Boyd raised an eyebrow at him.
"No, I just, I mean," Stiles sighed. "No, I don't. But you know, for once I'd like to have one normal day where I don't have to worry about you dragging me into some life-threatening scenario."
"Only in your dreams," Isaac mumbled.

"I don't have much information on him, but from what we know, he's not a friend, he doesn't want anything to do with us, and he has no interest in keeping his being a werewolf a secret from humans," Derek Hale explained when the group had made it to his loft half an hour later. "We need to exterminate him."
"Why can't we just run him out of town?" Stiles asked.
"And let others have to deal with him? No," Allison Argent, Scott's girlfriend, said sternly. "We need to take care of this ourselves."
"Allison's right, that wouldn't be fair to any other city he might end up in if we chase him out," Derek nodded. "Peter has tracked his scent to the river. We need to start there."
"Are we gonna interigate him first, or is it kill on sight?" Jackson Whittemore asked, walking into the loft followed by his girlfriend, Lydia Martin. The two sat on a leather chair, just outside the group.
"Kill on sight."

The group tracked through the muddy forest, weapons at the ready for Stiles, Allison, and Lydia, as they were the only humans. Everyone was on edge, the werewolves tentively sniffing the air, hoping to catch the scent of the Omega. Occassionally, they'd hear a twig snap, but thought nothing of it after they would see (or smell) that it was a small animal that caused the noise.
"Stop," Derek's voice cut through the air. Everyone stopped immediantly and listened. The humans could not hear it, but the wolves could- footsteps. Heavy footsteps.
The footsteps had paused shortly after they did. Derek didn't miss a beat. He was running through the forest after the Omega, his pack following suit. Lydia, Allison, and Stiles ran behind them, though not as swiftly.
Stiles's legs pumped back and forth, in his attempt to keep up with the group, but his breathing grew ragged. His lacrosse training was obviously not working. He sucked in his breathe and tried to push himself a little harder. Just as he was about to catch up with Lydia, his foot landed in a hole. Stiles came to a halting stop as his entire body collided with the hard ground.
Groaning, the teenager lifted his torso off the ground and look up and see that his entire group were now completely out of sight. He could hear them yelling- and growling- in the distance, but besides that, Stiles was now alone in the dark, with only a shotgun that he could barely work. Stiles rolled onto his back and sat up. He grabbed the gun and started to stand up, when the sound of a twig snapping shot through the dark. His head snapped to attention, as his heart started beating faster.
Oh please let that be another raccoon.
Two glowing red eyes shown through a loose cluster of tree branches.
"Oh shit," Stiles tried to leap to his feet, but a searing pain stopped him. His body fell back down, as he grabbed his ankle. Pulling back the pant leg, he saw that it was now swollen. "Oh God no."
Looking back up, the eyes were now behind another tree, this time closer. Stiles tried to stand again, this time hobbling along on his good foot. But another bought of uneven ground sent him back down.
"Shit, are you kidding me?" Stiles hissed under his breathe. He looked back to the eyes, who had now become the silhouette of a werewolf. It stood tall, probably six feet. It looked like a girl, but Stiles could not tell in the dark. All he was paying attention to were the claws that were ready to rip his throat out.
"Oh God, oh God, oh God," Stiles repeated as he backed away as quickly as he could. He didn't get very far before he hit the trunk of a tree. Stiles briefly closed his eyes in disbelief. Why did he always get left behind? When his eyes opened again, the werewolf was only a few feet away. He could see the details. It was a female, with long red hair and wearing a leather jacket and boots. She growled at him, slowly walking towards him, as if torturing him with the fact that in just minutes he would be her late night snack.
The wolf crouched, getting low to the ground and getting ready to pounce. Stiles sucked in his breathe, and watched. The moment the wolf leapt from her position, another figure flew through the air, knocking the wolf into the dirt.
It was a girl. Her back was turned to Stiles, but he could still see. She was short and skinny, that much was obvious. It looked like her skin was olive-toned, and her hair was dark and stopped half way down her back. She wore dark clothing- a leather jacket and pants, and a black shirt underneath. As Stiles observed her, the girl leapt at the werewolf with unnatural speed.
It was a blur, but Stiles could make out not one, but two sets of claws. The mystery girl was moving far to fast to be human. She was also brutally strong, as she had grabbed a hold of the wolf's arm and snapped it backward. The she-wolf would heal within a few minutes, sure, but to break a bone so easily...
The girl seemed to have grown bored with the repetitive moves the two were using. She took a chance and slid along the ground, stabbing the wolf in the leg with her claw-like nails. The wolf howled in anger before trying to make a grab at the daring girl. The wolf must have been in more pain than Stiles thought, because after she failed to grab the mystery girl, she turned tail and darted away.
Stiles stared in awe as the girl started to pick herself up and give chase. She took two steps forward before she stopped. From where Stiles was sitting, it looked like she was sniffing the air. He wanted to call out to her, but he couldn't find his voice. He didn't need to though. She turned around and he realized how very bad of a situation he had gotten into.
The girls eyes were completely pitch black. Tiny grey veins were formed around them, trailing down her cheeks. The eyes stared at Stiles, almost like they were angry. The girl gave out a furious screech, and that's when he saw the two huge fangs that sat front and center in her mouth.
She was a vampire.
Before Stiles could react, the girl was crouching over him, a hand raised as if she would attack him with her- rather small- claws. Stiles lifted his arms to shield his face from the attack, but there was a pause. There was silence. Nothing. Did I die? He lowered his arms back down, and saw that the girl was gone. Just vanished. In the distance, he heard howling.
Stiles scrambled around on the ground, trying to find his gun. In the fight between the vampire and werewolf, it had been half covered by leaves, but Stiles found it eventually. Stiles tried to stand again. His ankle still screamed in pain at any attempt to put even a tiny amount of pressure on it, but he slowly started hopping along on one foot, using trees to balance himself. After hopping for about 10 feet, he became exhausted, and decided to take a risk.
"Scott! Derek! Anybody!" he yelled out, as loud as he could. "A little help would be nice!"
It was only minutes later did he see his best friend come running over a hill to him.
"Stiles! What happened?"
"Dude, you are never going to believe this."
