Season 1 of Teen Wolf. Derek summons a friend, who just happens to be the mythical first werewolf.

Harry withdrew his hand after he and the half-mad werewolf landed and glanced around. He could smell the left over smoke scent from seven years ago and death, that too he could smell. The Hale house was still standing, but just barely.

"So, this is what came from Kate Argent's handy work, huh?" Harry asked under his breath. He turned to look at Peter, who was staring at him with a kind of fearful awe.

"What do you want with me?" Peter gulped, already starting to grow facial hair.

"Just to provide a reminder that I'm still around," Harry replied. "And to threaten you."

"Threaten? I'm an alpha, you can't threaten me!" Peter exclaimed, a bit hysterically.

Harry sighed and frowned at the werewolf. "You have to know that won't work on me. And besides, didn't your parents tell you about me? Derek certainly seemed to know about me. Derek, who you were about to attack. Derek, your nephew. Brother of Laura, your niece, whom you killed in cold-blood."

"Know about you? You're just a werewolf!"

Harry rolled his eyes and took a step closer to Peter. "I'm not just a werewolf. I'm the original werewolf. The First."

Peter's eyes widened then he narrowed his eyes. "There's no such thing."

"Oh, there is. The Fates really love to play around," Harry remarked. "BTW, time travel is a bitch. Don't do it."

Harry sighed again as Peter started to growl and he watched as the werewolf started to grow claws on his hands.

"Don't," Harry said, a hint of a growl in his voice. "It won't end well if you attack me." He felt his eyes start to glow and he closed the distance between the two of them and once again, reached his hand to grasp Peter's neck.

He forced Peter to the ground, not even straining. It had been a long 2,000 years since Fate and Destiny had unceremoniously taken him from his own time, changed him into a... He called himself a super-werewolf and dropped him off at the beginning of time. He was stronger, faster, easily more powerful than other werewolves and he had had a long time to test his power. Peter was a very small man in comparison to himself.

"I don't take well to werewolves killing their own kind," Harry commented, staring right into Peter's eyes. "Even if you were in a coma just a couple days ago or whatever, it doesn't mean you can kill your own family. Are you going to behave yourself now?"

Peter meekly nodded and Harry withdrew his hand, admittedly after stroking the nape of his neck reassuringly. He also cast the spell he usually performed on crazed werewolves that he deemed dangerous; he pushed down their wolf until it was almost not there, dampened it in other words. Peter wouldn't be able to shift at all or have the strength or the senses that came with being a born werewolf, not until Harry said otherwise.

"Good. Now, back to business. You say this is hunter territory now?" Harry asked, thoroughly looking around at their surroundings. Harry wondered how Derek could stand it, living here when there was a constant reminder of his dead family.

"Yes. What..."

Harry turned to look at Peter who had stood up and was looking around.

"Go on; I don't mind if you ask questions now."

"What are you going to do with me? And what am I suppose to call you?"

Harry grinned sheepishly. "Ah... I forgot to tell you my name! You can call me Harry for right now."

"For right now?" Peter stared at him like he himself was crazy. Which, Harry supposed, might not have been far off the mark.

"I usually change my name every hundred years," Harry replied. "Keeps the humans and mortals from growing suspicious. Right now, it's Harry. But as for what I'm going to do with you... Usually when I take a crazed werewolf under my metaphorical wing, he or she sticks with me for a few years. If I deem them less crazy and more... human after that, then they are free to go."

"You've done this before?" Peter asked as the night grew on and more stars came out.

"Of course. I take care of my kin," Harry replied. "Now, we'll leave the hunter business for tomorrow as it's getting late. And I don't want to leave this town alone for one night so we'll get a room."

Harry reached out a hand, palm up. "Your hand, please."

"What?" Peter questioned. "Why do you need my hand?"

"You are coming with me. I'm not leaving you alone," Harry calmly replied. "Now, do you want to be werewolf shishkabob for the hunters that are almost here or not?"

Peter startled and quickly, frantically, surveyed the clearing behind them. "What the hell did you do to me?"

"I just dampened your wolf," Harry remarked, grabbing Peter's hand and apparating them out of there.
