This was a request from mimifoxlove who wanted to see another NonHuman!Stiles fiction (a hellhound version though). So here it is, following the story of Hellhound!Stiles from Season 1 of Teen Wolf… The Hound of Beacon Hills (title based on the story titled called 'The Hound of Bakervilles' from the Sherlock Holmes stories which had a hound that could shoot flames from its mouth).

Disclaimer: I do not own Teen Wolf nor anything affiliated with it.

Disclaimer #2: The pic I used for the cover photo is one I found on the internet. It is one that I edited a bit to make it relate to the story. The original is by HanMonster on deviantart and it is called "Generic rainbow dog". It's not mine!

Summary: AU. When Laura and Derek Hale went to their home that night, they saw it in flames, but they also heard a small yipping from one corner of the woods. Following the sound they discovered a small puppy, but this was no ordinary puppy, it was a hellhound, one who went by the name of Stiles. Sterek with Scott/Stiles friendship. Warning: BoyxBoy love, possible smut in later chapters, and eventual mpreg.

*The Hellhound of Beacon Hills*

"Oh no…" Laura gasped out as she and her younger brother Derek came around the bend and saw their home, the Hale Manor, up in flames. They had smelled the smoke and sulfur in the air… as well as some wolfsbane. It was coming from the direction of their home and they had hoped—prayed to God—that it was not their home that was attacked—but another—and that they had mistaken the wolfsbane for something else…

They did not.

It was their home in flames. And the flames were indeed started with wolfsbane. This was a murder of their family; a family that wasn't just made up of werewolves but of humans as well. The only ones who could commit this mass murder were the hunters… and Derek felt a pang at his gut for he knew that it was his fault. He was the one who let her in, despite her being an Argent. He was the one who allowed her to get close to him and as a result his family. It was he who killed his family and he was feeling all the repercussions of it… of betraying his family.

"Derek…" his sister spoke to him, her eyes glowing red. She was the alpha now; the alpha of a pack size of two—and that was including herself. "… we need to leave. Now. There's no more place for us here in Beacon Hills."

"But Laura, where will we go?" Derek asked his new alpha. They were only teenagers; he being sixteen and she eighteen. Where could two teenagers possibly go after their whole family's been murdered?

"I don't know. Somewhere… outside of town maybe… New York?"

"Laura… I just don't see—"

Yip. Yip.

The sound interrupted Derek's sentence and both werewolves turned to the sound of that strange crying. The two siblings glanced at each other and followed the sound to its origin. A little bit of a ways' in the woods there was this tree, and under this tree was a single brown, moving mass, very small in size with a short bobbed, pale yellow tail with short pale yellow legs. It was a puppy, but a strange one indeed. The small brown ball of fur looked up when the two werewolves arrived, the home burning behind them in the distance behind a few rows of trees. Immediately the puppy stood and got into a pose that should be a threatening one but instead just looked really adorable. It began to growl behind small white fangs, ruby red eyes staring up at them. "What… in the world… is that?" Derek asked, looking down at the dog (?) with a questioning gaze, the current dilemma of the Hale Manor in flames pushed to the back of his mind.

For a moment Laura remained silent as she tried to comprehend what she was seeing and looking at. "I think it's a hellhound."

"A hellhound? What's that?"

"It's kind of like a werewolf, like us, only it's not affected by the moon." Derek made a small sound that sounded off his intrigue. Laura then noticed blue and red lights flashing, lights heading down the road that lead to their home. She then heard the sirens. "Come on Derek. We need to leave. Now." With that she began to walk away, heading west towards the opposite end of the United States. But Derek didn't move. He started at the pup as Laura began to walk away. When she realized that her brother wasn't following her, she stopped and turned around to look at him. "Derek." She called to him, urging him to move.

"Where is its parents?" Derek heard himself ask… almost out of worry.

"I don't know but I'm sure they'll come back. Now come on."

"… We can't leave it here… the humans could find it like we did."

Laura was about to refute him but sighed instead, seeing his point. It would be best if the humans didn't know the existence of mythical creatures and even a blind man could see that this puppy was no ordinary dog. "Fine. We'll move it farther away from the house but then we're out of here." Derek nodded and bent to pick up the puppy when instead it snarled, a red light appearing behind its mouth. "Derek!" Laura called out to him frantically, moving towards him. "Watch out! Even the puppies are danger—"

Suddenly the puppy sneezed and a puff of flame and smoke erupted from its mouth towards the floor, propelling the puppy back into the trunk of the tree. It hit the tree and fell onto the ground, red eyes blinking in confusion as it looked around. It looked up at Derek and as if it forgot that it was (trying) to threaten him, it yipped happily and flashed its fangs at him in a smile, the pale yellow tail wagging gently. "Dangerous?" Derek completed Laura's sentence with obvious doubt. "This hellhound looks like he can't even harm a fly much less me."

Laura sighed and placed her hands on her waist. Glancing back towards the house the lights of the emergency vehicles were already at the house and she could faintly see shadows of the humans there trying to put a stop to the flames. What does it matter? Laura thought bitterly. Our family's already dead. "Derek, let's move." She said for one last time as she began to once again walk away.

Derek reached forward and picked up the hellhound puppy. It struggled a bit in his arms before relaxing, nestling its head on the crook of Derek's elbow. Derek followed behind Laura, they walking for a while until they reached the two mile mark away from the Hale Manor. "This should be good." Laura stated as she pointed to a tree's roots which created a basket of some sorts.

Derek nodded and looked down at the pup in his arms… a pup which was sleeping. He sighed and pulled the puppy away from him, a movement which woke up the tiny hellhound. Derek held the puppy before him at face level, staring at it intently. The puppy was panting happily, unbeknownst to the fact that it was about to be left behind. Instead the pup reached out and licked the werewolf's nose with one silky, wet tongue. Laura chuckled and crossed her arms before her chest. "Looks like it likes you."

"Shut up." Derek said as he knelt and put the puppy down between the roots. The puppy laid down and rolled onto its side to stretch. Derek watched the hellhound for a few seconds before looking up at Laura. "What will happen if its parents don't come back for it?"

Laura thought about it for a minute. Trying to think back on what she read about hellhounds. "Well… they're more like wolves in the way that they need a pack to survive, to learn and live and such. Without its parents it'll probably die."

Derek sighed heavily and looked at the hellhound once more before standing. He said nothing as both he and Laura began to walk away from the puppy. When a small whimpering sound arose the two werewolves nearly hesitated in their walk but continued on nonetheless. The whimpering continued, getting fainter and fainter as the two Hale siblings walked away. When the sound finally disappeared Derek felt his eyes close shut and he sighed as he came to a stop. Laura too sighed and she turned around to face him for she continued walking when he stopped. "Derek… no." She said simply, understanding the reason for why Derek stopped. When he said nothing she continued. "No. We can't take it with us. We're alone and we're about to go on a long journey far away from here. We simply can't."

"Laura…" Derek sounded. He felt uneasiness with the hellhound pup. Both Laura and Derek knew straight out that the puppy was abandoned already by its parents. It was probably the runt of the litter since it was so tiny already. The parents wouldn't come back for it. It was an orphan on account of its own family and Derek felt that connection since they too were orphans now (on his own account due to his own stupidity). Derek wasn't usually one to be noble but he couldn't just let another being die, not when he can do something about it.

Laura said nothing. She merely rolled her eyes and began to lean on the nearest tree, a silent approval. Derek turned on his heels and backtracked to where he had left the hellhound puppy, as he went the whimpering returning, though much softer and more spaced out than before. When Derek reached the tree the puppy was curled up in a ball, obviously feeling abandoned yet again, it's whimpering slowly dying out. "Hey hellhound." Derek greeted it as he knelt on the ground. The pup's ears rose and it then lifted its head, its red eyes staring into hazel ones. Derek could see the bobbed tail begin to wag again and Derek felt a warm feeling grow inside of him. "Sorry for almost leaving you." Derek apologized as he picked up the hellhound and held it close to him. The pup licked the underside of his chin and face, its sign of an apology well accepted. "Come on hellhound, let's go."

"Stiles…" The word was softly whispered out. Derek looked down at the pup in his arms with a questioning gaze. The puppy was smiling up at him, pink tongue hanging out form the side of its mouth. "Stiles… name is Stiles…" The sound seemed to be coming out from the puppy's open mouth but the mouth wasn't moving, only the body as the hellhound panted and breathed.

"You can talk?" Derek asked, almost not believing it himself if he wasn't actually there listening to the hellhound speak.

The puppy continued smiling up at him, panting heavily in excitement and happiness. "Stiles… name is Stiles…!"

"Is that all you can say?"

"Stiles!"

Derek sighed and one corner of his lips turned up slightly. "Alright Stiles… let's go."

"Stiles! Stiles!"

As Derek once again met up with Laura and the two once again resumed their journey to find a new home, the puppy was already fast asleep in Derek's arms, the tiny brown creature breathing softly as it slept. Derek couldn't help but to watch over that tiny sleeping form as their journey progressed. Though that night their home had been set aflame and their entire family was murdered by some hunters, one of which Derek practically invited into their home… Derek found a reason to keep going on in one tiny little ball of brown fluff.

A hellhound named Stiles.

*The Hellhound of Beacon Hills*

Nine years later…

In the end, Laura and Derek never went to New York. Instead they stayed in Beacon Hills and together they tried to put the ones responsible for the fire in jail with no such luck. Instead the case was put on hold and no suspects were ever found nor trailed. There were people who thought that Laura and Derek had actually set the house on fire but they were not sure of a motive. Still, without any true evidence the case really had no leads.

And of course, Kate Argent, the one who had tricked Derek and started the Hale Manor fire left town immediately after to save her own hide.

Regardless, Laura, Derek and Stiles live in small house in a residential area in downtown Beacon Hills, living as normally as possible… with all the cautious stares and blaming glares and with all the suspicion that hung around their broken family. Especially that of the hellhound Stiles, who had proved himself to be truly a remarkable creature.

"Derek have you seen Stiles around?" Laura asked her brother as she was preparing the dinner for them.

"He went outside a moment ago."

"Derek."

"What?"

"Was he in his hellhound form? In broad daylight?"

"I wouldn't say broad daylight." A third voice arose from the front door. "The sun is setting out there… not really as bright as in broad daylight." In walked in the hellhound Stiles, his paws padding across the linoleum floors of the kitchen.

The hellhound had grown into quite a beautiful creature. The first major change that the two werewolves noticed as the hellhound pup grew was that his brown fur began to have color in it. It began to change color at the tips of the fur, at first colors of reds and oranges, and then eventually yellow, green, blue and purple. The hellhound was in fact a rainbow colored hellhound, his base fur still being brown but now that he was fully grown, waves of those rainbow colors swept over his body… except for the bottom half of his legs and tail. This was the second major change the Hale siblings had noticed. The pale yellowness of these particular body parts began getting scaly… very similar to that of a snake's body. The color was also becoming brighter, and brighter, changing from a pale yellow to a bright dandelion yellow. The tail had also lengthened to about two feet in length and had actually turned into a snake, the first half of an eyelash viper to be precise. One that did in fact hiss and snap at the Hales at time without any accordance with Stiles himself… it was a true legit snake at the end of Stiles' tail and it had a mind (and attitude) all its own.

The other changes were more subtle. The third change came around Stiles' first birthday when the hellhound who had four toes on each paw, suddenly developed a fifth claw extending down from the pastern and the hock of his legs. And of course the front new claws were shorter than the ones in the back. While the claws on Stiles' front legs were about an inch in length, the ones in the back were about two point five to three inches in length. Why? For no apparent reason for those claws seem to have no real value at all and the Hales not being hellhounds (and hellhounds being so rare a species), didn't know why the claws were even there. Another change was that Stiles' tongue transformed from a regular rounded tongue at the end to one with a sharp point, much like a demon's tongue (when it isn't forked like a snake's). It also became longer and redder in color.

The other change was in the fire aspect. Before the hellhound couldn't even so much as lite a match but now the hound can easily lite a fire in the fireplace or even burn the woods down (maybe even the town). He had gotten significantly stronger and more agile as well, rivaling that of Derek (though the hellhound was still more wolf like in nature and would never be stronger than Derek and especially Laura). Another huge difference (not only from Stiles' younger version but from everyone else, human or non-human) was Stiles' aging process. Over the past nine years it became apparent that hellhounds age differently, at least in their first few years of life. From the moment the Hales found him to the age of six the hellhound had aged much quicker than the werewolves (and as for that matter humans). This was more apparent when Stiles shifted into his human form (another change that came with age).

That very same hellhound that just padded into the house through the doggy door in the front (yes there were doggy doors, one in the front and one in the back, extra-large doggy doors for Stiles in his hellhound form stood as tall as a husky and even then he barely fit through them) shifted into a human and sat himself down at the kitchen table. The human was already sixteen for when he had turned six, in human years he was already thirteen. From that moment on the hellhound began to age normally, needing a year to gain a year, no more, no less.

Stiles stretched his arms above his head and yawned. When he opened his brown eyes (another change only apparent when he was human) his view was that of two identical pair of death stares from Laura and Derek Hale. "What?" The teen asked as he let his arms drop to the table.

"How many times do we have to tell you?" Derek began. "Don't go outside in your hellhound form in daylight."

"I wasn't seen."

"That's not the point Stiles!"

Laura sighed and began to plate some food. "Derek." She crooned to him. "If he isn't seen then we have nothing to worry about."

"But Laura—"

"Now let me finish." Laura walked over to the table, two plates of food in hand and placed them before the boys. "Stiles, that does not mean you can keep risking yourself like that. It's dangerous out there and if you're seen you could be in big trouble, trouble that could lead to death and neither one of us wants that… right?"

"Right…" Stiles sounded in a defeated tone. "I just… I just want to socialize with people… I've been home-schooled all my life by you guys… not that I don't appreciate it 'cause I do! Honest! But I don't know…"

Laura and Derek glanced at each other. Laura went around a placed a hand on Stiles' shoulder. "Hey… you know that it's dangerous for you out there. One false move from you and you'll get angry or scared and then poof! There goes the town… literally."

"I know." Stiles sighed with dejection. "I know…" He repeated again in a sadder tone.

A few years ago the three of them went camping; this was when he was still just a small puppy. And like the idiot that he is, Stiles got separated from the Hales and still being unable to shift into a human, the hellhound found himself pinned between a cliff and a hungry bear. Fearing for his life the young hellhound spontaneously combusted, his body being engulfed by flames, efficiently scaring off the bear but the fire couldn't be put out. It caught on some trees but luckily Laura and Derek showed up and calmed him down (and of course put out any lingering fires). It was definitely a close one.

Laura came back to the table with her own plate and drinks for herself, her brother and pet (?)/friend/adopted son mix. "Eat up guys." Laura said as she began to cut into her steak and mashed potatoes.

"Thanks sis." Derek said as he too began to eat.

"Yeah, thanks Laura." Stiles added. Stiles sighed as he began to eat, his heart longing for some companionship that didn't come from Laura and Derek. It wasn't like he didn't appreciate them for being there for him, but a person needs more than two people in their lives. Even Laura has her friends from work (Derek on the other hand doesn't socialize much so even at work he doesn't have any real friends but he's got acquaintances).

The hellhound eventually in the middle of his meal sighed again and looked out the window in the kitchen to look at the setting sun as it dipped behind the earth. He continued to watch the setting sun, unbeknownst that the two Hale siblings were watching him carefully, Laura feeling a bit dejected from Stiles' lack of companionship and Derek being unsure of what to think of Stiles confession of wanting other friends. On one hand he felt relieved that he wouldn't have to spend so much time with the talkative, energetic hellhound (they found out that Stiles actually has ADHD a while back and thus they got his Adderall to help calm him down); but on the other Derek just felt really uneasy about the idea of Stiles hanging out and rubbing against other people, people that probably couldn't be trusted, or want to hurt him or worse…

…take Stiles away from him.

Derek closed his eyes and shook his head, thus shaking his head clear of that last thought. Stiles wasn't his, nor did Derek think that Stiles was his. They are simply roommates with his sister, they all sharing a bond of being orphans, the three of them making up their own little family. Stiles was nothing to him. At least nothing of great importance. Derek opened his eyes and looked at Stiles once more, his gaze still looking out the window in a far-away look.

If Stiles wasn't important to Derek… then why was he feeling so unbearably uneasy…?

*The Hellhound of Beacon Hills*

Well there's chapter one. Scott will be introduced in the next chapter along with finally getting on track with the beginning of Season One (hint, hint, nudge, nudge).

So mimifoxlove, how'd I do on the first chapter? Under your expectations, right on par, or exceeded them?

As for the rest of you… please review!
