This is my first fanfic so I hope you all like it! I have tones of ideas for where I want to add my OC, and where I want this fanfic series to go! But requests are always welcome! Basically a HTTYD fanfic where Hiccup has a Sister! Here's a little description of her!

Hadley Haddock: Age 13, Auburn hair braided down the left shoulder, green eyes, freckles, green long-sleeved shirt, brown skirt, dark green leggings, brown boots, Dark green braided headband, and a brown braided belt.

I tried to make her look like Hiccup's sister as much as I could. I was going to dive right into the TV series showns and add Hadley in, along with making some of my own 'episodes', but decided to start with where it all began! Enjoy!

Chapter 1

This is Berk. It's twelve days North of hopeless, and a few degrees South of freezing to death. It's located solidly on the meridian of misery. My village. In a word? Sturdy. It's been here for seven generations, but every single building is new. We have fishing, hunting, and a charming view of the sunsets. The only problems are the pests. You see, most places have mice or mosquitos, we have…

The door to the Haddock house hold is pulled open by a fifteen year old boy, and thirteen year old girl, then quickly slammed shut when they see a Monstrous Nightmare blast at them. The two siblings share a glance.

"Dragons…" They say in unison.

Most people would leave, not us, we're Vikings. We have, stubbornness issues.

The two teenagers run out of the burning house dodging around several Vikings fighting to get through.

My names Hiccup, and that's my sister Hadley. Great name, I know. At least my sister's got a normal one. But it's not the worst. Parents believe a hideous name will frighten off gnomes and trolls. Like our charming Viking demeanor wouldn't do that.

A Gronkle lets out a blast, sending a Viking flying into Hiccup, who falls into Hadley.

"AHHHH, Morning kids!" Said Viking leaps up off of the siblings. The two head off through the village getting multiple looks and comments.

"What are you two doing here?"

"Get inside!"

"What are you lot doing out?"

"Get back inside!"

A Deadly Nadder suddenly flies in front of the two, blasting the pathway with fire. Before they can run into the inferno, two large, meaty hands reach out and grab hold of the siblings.

"Hiccup! Hadley! What are they doing out aga- what are you two doing out? Get inside!" The man holding them releases them, tossing them to the side.

That's Stoick the Vast. Chief of the tribe. They say that when he was a baby he popped at dragons head clean off its shoulders. Do we believe it? Yes we do.

"What've we got?" Stoick turns and asks a Viking standing behind him.

"Gronkles, Nadders, Zipplebacks, oh and Hoark saw a Monstrous Nightmare." A blast from another dragon send the Viking ducking behind his shield.

"Any Night Furies?" Stoick asks, swiping a stray burning ember off his shoulder guard.

"None so far."

"Good."

Meanwhile back in the middle of the village, Hiccup is met with the blacksmith, as Hadley runs off to the village healer.

"Oh, nice of you two to join the party! We thought you've been carried off!" the blacksmith exclaims, translating the village healer's ruins written in the ground of the forge/healers hut.

"Wha? who us?" Hadley exclaims.

"Come on, I'm waaayyy to muscular for their taste! They wouldn't know what to do with all, this!" Hiccup turns to the blacksmith, gesturing to his none existent muscles, making his sister laugh.

"Oh don't you even start! You've got as much muscle on you as I do!" Hiccup says turning to Hadley with a laugh.

"Well they need toothpicks don't they?" The blacksmith jokes, making Hadley laugh even harder, earning a wack on the head by the healers staff for not focusing.

Hiccup runs over to the window, throwing open the shutters to gather broken weapons, as Hadley heads to the healer's part of the building to start making medicine for the injured.

The meathead with attitude interchangeable hands is Gobber, and the little old lady with a staff and anger issues is Gothi. We've been their apprentices ever since we were little, well, littler.

Back with Stoick, the Vikings run down the pathway to the catapults.

"We move to the lower defences, we'll counter attack with the catapults!" The Vikings run of to do as ordered. A Monstrous Nightmare glides low and sets a building on fire.

See? Old village, lots and lots of new houses.

"FIRE!" A Viking yells out for the fire brigade. Said teams runs by the window of the forge, and Hiccup leans forward to get a better look.

"Come on! Hurry up!" One of the teens on the fire brigade shouts.

Oh and that's Fishlegs, Snotlout, the twins, Ruffnut and Tuffnut and…

A Viking girl with blonde hair puts out a fire and turns around, just as another blast is thrown behind her.

Astrid! Oh there job is so much cooler.

Hiccup leans out of the window, hoping to catch another glimps of what the teens are doing only to get pulled back in by a curtain blacksmiths hook hand.

"I don't think so!" Gobber teases, hauling Hiccup back into the forge.

"Oh come on, let me out, please! I need to make my mark!" Hiccup exasperated. Gobber droped him to the ground to stand next to his sister who came over to see what they were arguing about now.

"Oh you've made plenty of marks, you and that sister of yours, all in the wrong places!" Gobber points to the two, pushing Hiccup back to his station.

"Come on Gobber! Give him a chance!" Hadley complains, moving to stand by her brother in support.

"Yes! Please! Two minutes, I'll kill a dragon, my life will get infinitely better! I might even get a date!" Hiccup exclaims.

"Astrid? Really?" Hadley turned to look at her brother, a look of bewilderment on her face. Astrid had hated the both of them, thinking they were just the village screw-ups everyone made them out to be. Sure they had a few contraptions and inventions gone horribly wrong, but everybody messe up from time to time, they just do it more… frequently.

Ignoring Hadley's comment, Gobber continues with is rant.

"You can't live a hammer, you can't swing an axe, you can't even throw one of these!" Gobber counts of the items of things Hiccup can't do, then picks up a bola, which a Viking hurriedly runs to the window and grabs and throws up to the sky, effectively trapping a Gronkle. Hiccup rushes to the back of the forge to another one of his contraptions he made.

"Ok fine, but this," He says gesturing to the 'Mangler', what he named his invention, "will throw it for me!" Hiccup gives his invention a tap, accidently letting a bola fly out of the machine. Hadley ducks, the bola just missing her head, and sailing past Gobber, hitting a Viking in the head. Hadley and Gothi rush to the Vikings aid.

"You see, now this right here is what I'm talkin' about!" Gobber advances forward on Hiccup.

"He's got a point Hiccup, we've already caused enough damage the past four raids, let's just let everyone have one raid 'Haddock kids free'." Hadley states, back at her brothers side. She loved her older brother, even though at times he was rather overprotective, he meant well.

"Mild calibration issue! And Hadley, you're supposed to be on my side!" Hiccup look towards his sister, a pleading look in his forest green eyes.

"No! Hiccup, if you ever want to get out there, to fight dragons, you need to stop all… this." Gobber stood back gesturing to Hiccup in no general area.

"But you just pointed to all of me!" Hiccup said, flabbergasted, not knowing what else to say.

"Yeah, Gobber. How is he supposed to stop all of him. To be frank, I don't think that's physically possible!" Hadley shot back. Gobber sometimes got out of line and she had to straighten him out to keep him from going too hard on her brother. But seeing as he completely ignored her, again, she figured four raids of causing havoc must have pulled the last straw.

"Yes, that's it! Stop being all of you!" Gobber continued.

"Ohhhh,"

"Oh yes."

"I see what you're doing. You sir are playing a dangerous game. Keeping this much raw, vikingness contained! There will be consequences!" Hiccup shouted.

"I'll take my chances. Sword. Sharpened. Now." Gobber said turning to grab a sword on tossing it into Hiccups arms. Hiccup turned to Hadley, giving her an exasperated look. She had to help her brother. She winked at him, and laughed at the confused look on his face. Hiccup just kept walking to the sharpener and raised the sword onto it.

One day I'll get out there. because killing a dragon, is everything around here. A Nadder head is sure to get me at least noticed. Gronkles are tough, taking down one of the those would defiantly get me a girlfriend. A Zippleback? Exotic. Two heads, twice the status.

Up on one of the catapults, Stoick and his men are witnessing the damage.

"They found the sheep!"

"Concentrate fire over the lower bank!" Stoick bellowed, moving the catapult to aim and take out a Nadder.

And then, there's the Monstrous Nightmare. Only the best Vikings go after those. They have this nasty habit of setting themselves on fire.

"Stay low! I'll take care of this." Stoick stood up, facing the Nightmare with his hammer in hand. He started nocking the dragons head back and forth until a familiar whistle could be heard in the distance. Stoick looked up into the sky.

But the ultimate prize, is the dragon no one's ever seen.

Hiccup and Hadley dropped what they were doing and rushed to the window of the forge.

We call it the…

"NIGHT FURY! GET DOWN!" A purple blast is shot at the catapult Stoick and his men were standing on, forcing them to jump.

"JUMP!" Stoick called to his men.

This thing never steals food, never shows itself, and…

Another blast is shot at the same catapult and a black shadow zoomed through the sky.

never misses. No one has ever killed a Night Fury. That's why I'm going to be the first.

Hiccup and Hadley stood back from the window after the display the Night Fury put on. Hadley looked over to her brother and saw the determined look written clear on her face. Time to put her plan into motion.

"Hey! Gobber! I think they need your expertise out there!" Hadley shouted to Gobber. She then turned to Gothi and called out, "Gothi, I think someone's hurt from the fall from the catapult! I can stay and make some pain ointment." Gothi nodded and headed to the scene of the crime. Gobber was a little more hesitant as he turned towards the siblings.

"Stay. Put. There. You both know what I mean!" With that he turned and ran into battle with the signature, Hooligan war cry. Hiccup turned to Hadley, staring at her, a look of surprise and confusion.

"What are you waiting for? Let's go catch a Night Fury!" Hadley ran over to the Mangler, yanking Hiccup with her as they both lifted the contraption and started to run to the outskirts of town.

"Thanks Had. I didn't think I'd ever get a chance if Gobber didn't let up." Hiccup said stopping her just before they left the front door of the forge/healer's hut.

"Hey, don't mention it. I saw that look of determination in those eyes. You were going to go no matter what. Might as well go with you to make sure you don't get killed!" They looked at each other, sharing a knowing smile, and rushed out the forge.

As they ran through the village they got more shouts and annoyed looks as they passed with their invention.

"Hiccup, Hadley, what are you doing!"

"Come back here you two!"

"Kids!"

While the two Haddock kids were running through the village, Stoick was having problems of his own. A group of Nadders surrounded some sheep, but before the could fly off with them, a weighted net was thrown over top of them. On particularly brave Nadder stood up, firing out a blast.

"Mind yourselves! The devils still have some juice in them!" Stoick shouted as he jumped on the Nadder, clamping its jaw shut.

Meanwhile, Hiccup and Hadley just reached the top of the hill overlooking Raven's Point. They set up the Mangler and Hiccup stood in his place ready to shoot when the dragon showed itself.

"Come on, give me something to shoot at, give me something to shoot at…" Hiccup chanted to himself. All of a sudden, Hadley looked to the sky as well, seeing some stars disappear, and then reappear.

"Hiccup!" Hadley whispered, pointing to the sky where she saw the Night Fury. Hiccup looked at where she was pointing, and aimed in that direction. When they heard the tell-tale whistle of the Night Fury, Hadley stood behind Hiccup as he got ready to shoot. The Night Fury dove down, firing a purple blast right in front of the Haddock kids. Hiccup aimed and took his shot. The momentum of the shot knocking him off of his place on the Mangler, and crashing into Hadley who was standing right behind him.

"Woah!" They both shouted as they fell to the ground. Hadley got up quickly, hauling Hiccup to his feet, just in time to, as they watched the Night Fury fall out of the sky and land near Raven's Point.

"Oh I hit it… YES I HIT IT! Please tell me somebody else saw that!" Hiccup exclaimed, pumping his fists in the air and turning towards Hadley. If only he saw what Hadley say as he turned around.

"Um… Hiccup? Don't. Move." Hadley whispered, putting her hands up in a defensive position.

"Huh?" Hiccup said, turning around in confusion, only to come face to face with a Monstrous Nightmare. "Except for you…" Hiccup turned to Hadley and grabbed her wrist, pulling her away from the dragon.

"HADLEY RUN!" Hiccup screamed as they both ran for their lives towards the village. Hiccup's scream got the attention of Stoick as he was tying up some Nadders.

"Ugh… Do NOT let them escape!" He called out as he ran to the children's aid.

Hiccup and Hadley ran through the village, running from the Nightmare hot on their trail. They came across a support beam. Hiccup saw this and yanked Hadley to hide behind it. Hiccup wrapped his arms around her to protect his little sister as they both looked around the edge of the now flaming pole. Had only they looked the other way they would have seen the Nightmare, getting ready to have a little morning snacks on the two. All of a sudden, Stoick jumped out and tackled the Nightmare to the ground. The two Haddock kids moved to the other side of the pole as Stoick threw punch and kick at the dragon making it flee.

Oh, and there's one more thing you need to know…

The pole now completely destroyed at the bottom collapsed and leaned to the side, exposing the two teens, Hiccups arms still wrapped protectively around his sister. They turned around to watch as the flaming tower fell down to the docks, making worried faces at the destruction. Hiccup let go of Hadley and they gave each other a nervous look as they turned to the chief.

"Sorry, Dad." They said in unison.

"Ok, But I hit a Night Fury." Hiccup quickly blurted out. He gave a yelp as he was picked up of the ground and carried back to the plaza, Hadley following quickly behind.

"It's not like the last few times Dad!" Hadley said, trying to reason with him and lower his anger.

"Yea, I mean you guys were busy, and I had a very clear shot, it went down just off Raven Point. Lets get a search party out there before it-" Hiccup never got to finish his sentence as Stoick roughly set him down and turned to him.

"STOP! Just… stop. Every time you two step outside, disaster falls! Can you not see that I have bigger problems!? Winter is almost here and I have an entire village to feed!" Stoick shouted. Hiccup and Hadley looked at each other, then around at the Vikings around them.

"Well between the three of us, the village could do with a little, less feeding, don't you think?" Hadley said, trying to make a joke out of the whole thing.

"This isn't a joke Hadley!" There goes that plan, Hadley thought to herself.

"Why can't you two just follow the simplest orders and stay where we put you!?"

"I can't stop myself! I see a dragon and I just have to… kill it, ya know? It's who I am Dad." Hiccup explained.

"And wherever he goes, I go." Hadley stated.

"Oh Thor," Stoick muttered, putting a hand on his forehead, rubbing at the headache to soon occur. "You are, many things Hiccup, but a dragon killer is not one of them." Hiccup lowered his head in defeat.

"And Hadley," Stoick continued, "You are still too young to be following your brother into whatever trouble he inevitably gets himself into. Get back to the house you two. Make sure they get there!" Stoick said, directed to Gobber.

"I have this mess to clean up." Gobber walked up to the two distraught siblings and pushed them towards the Haddock house hold. As they were walking, they just happened to pass the other teens.

"Quite the performance!" Tuffnut stated in between laughs.

"I've never seen anyone mess up that badly, nice going you two, that helped! Snotlout laughed at the two.

"Thank you, thank you, we were trying so," Hiccup said quietly.

"Ow!" Snoutlout yelped as Gobber pushed his helmet over his head and shoved him away from the siblings.

When they reached the steps to the chiefs house, they started the trek up.

"I really did hit one." Hiccup said, turning to look at Gobber over his shoulder.

"Sure Hiccup."

"He never listens." Hadley complained, walking with her brother in front of Gobber.

"Well it runs in the family."

"And when he does, it's always with this disappointed scowl, like someone skimped on the meat in his sandwich." Hiccup turned around as they were met by the door, to Gobber. "Excuse me barmaid! I'm afraid you brought me the wrong off spring! I ordered and extra-large boy with beafy arms, a skilled girl with stronge muscles! These kids here, they're walking, talking fishbones!" Hiccup stated in an impersonation of their Dad. Hadley had to try really hard to stifle her giggles.

"Now, your thinkin' about this all wrong It's not so much what you two look like, it's what's inside that he can't stand!" Hiccup and Hadley stood at the door, staring at Gobber looking thoroughly confused and hurt.

"Thanks Gobber. Way to brighten our spirts." Hadley said, sarcastically.

"Thank you, for summing that up." Hiccup said with the same amount of sarcasm used. They both turned to open the door to their house when Gobber stopped them.

"Look the point is, you two need to stop trying to be something you're not." Gobber softly explained.

"We just wanna be one of you guys." Hiccup said sadly turning and walking into the house with Hadley hot on his heels. Gobber sighed and started walking back down to the village.

Inside the Haddock house, Hiccup started rushing around grabbing his dagger, sketchbook and charcoal pencil.

"What are you doing? And where are you going?" Hadley asked, though knowing full well where her brother was headed.

"You should know," He looked up with a smirk. "You coming?" He turned and started walking towards the door. Hadley chased after him as they ran into the woods. Hiccup turned to Hadley and smiled.

"Let's go find us a Night Fury."
