A great thanks to everyone who reviewed, favorited and followed.

A great thanks to KillerGeishaYumi for suggesting I use Book!Toothless.

I have changed some things on last chapter, mainly added a stutter to Toothless, like in the book, and corrected grammar mistakes, if you didn't understand some parts of it last time, I advise you to go read it now.


Cami wasn't expecting to find five tattooed and scarred, dead men as she walked into the morgue, she had been called mid-morning, the Night Fury had been seen on the scene of the murders, and she wanted to know if the murders could be useful or not for her investigation.

She looked at the dead men and saw two were missing their heads, one had a hole in his stomach area, another had his throat cut and the last one didn't have any outer damage.

She walked towards the coroner who was waiting for her, clipboard in hand.

"Good morning detective." He greeted Cami politely.

"Morning doctor. Did Night Fury kill these men?" Cami asked, going straight to business.

"Well, these three," He gestured to the beheaded men and the one with the stomach hole, "Were killed by some sort of laser blast, that one," He pointed to the one with the cut throat, "His throat was slashed by five small and very sharp objects, by the direction and position, I was able to assume they were made by some sort of clawed glove and the user used it in his right hand, while that one," He pointed to the remaining one, who showed no signs of outer damage,"Much like the last man with these tattoos, he was missing his lower jaw, left first molar tooth, and I found traces of cyanide in his stomach, so I assume this man killed himself while the other ones were attacked and killed."

"So..." Cami gestured with her hand, she hadn't gotten her answer yet.

"That's all I can tell you detective, I know for sure the last one killed himself the very same way our first John Doe did, the other ones, well that's why you're here." The coroner said simply, like five dead weren't a big deal.

"So I assume you haven't been able to identify any of them?" She rubbed her temples, these dead men were starting to annoy her, and they were dead!

"That is correct. There's no record, on the police files for their DNA or finger prints and I didn't find any dental records." The coroner nodded.

"Do you think you're friend could help us identify the cause of these injuries?" She gestured towards the beheaded man.

"He might if you give him a call I'm sure he'll come check them out." The coroner nodded again.


A few hours later, Dr. Moriarty Neil went to the police morgue to inspect the bodies, as per Camicazi's request.

"Good morning doctor, thank you for coming." Cami shook his hand and motioned for the bodies, "As I said on the phone, there have been five murder victims, three of them show injuries of a weapon we don't recognize, can you help us in that department?"

The Dr. examined the bodies, mainly the injuries, looking closely and touching the wounds with his glove-covered hands.

"At what temperature were the bodies when you found them?" He asked Cami, who opened the file.

"They were at," Her eyes widened, "150ยบ F." Dr. Moriarty nodded, not looking surprised at all.

"It was some kind of weapon that heated infrared so much that it shot out a sort of laser."

"Can you tell who built it?" Cami asked, hopefully it would lead her to the killer or Night Fury.

"I'm sorry, I can't. Many people have tried to develop this technology for a long time, I doubt you'd easily find it out on the streets."

Cami nodded, said her thanks and shook the scientist's hand. Moriarty went out of the morgue and grabbed his phone, quickly dialing a number, a smirk on his lips.

"Model 83A is in Berk."


"And you learned all of that from a talking raccoon? I'm sorry Hiccup but that's kind of hard to believe." Fishlegs told him after Hiccup finished his explanation, they were in his computer room, basically the only place they could talk without Astrid hearing them. It was now mid morning.

"You should have seen him Fishlegs, he was... amazing, he spoke, he actually had felling like sadness and anger." Hiccup tried to convince Fishlegs once again.

"Alright," Fish sighed,"So what do we do now?"

"We need to find this guy." Hiccup clicked on a few keys and a police file appeared on screen, he was tall, had red hair and brown eyes, his jaw was sharp and his check bones were quite low, he had glasses sitting on his nose, "Dr. Moriarty Neil, he's a genius basically, the only reason he's in the police files is because of a parking ticket three years ago. He's the leader's right arm, and from what I understood, he oversees and partakes in the genetic mutation operations."

"How do you intend on finding him, may I ask?" Fishlegs questioned his friend, he thought it was stupid, going after this guy based on the information given to them by a talking raccoon, he didn't even believe there was a talking raccoon, and now he had to believe in what it said?

"Well Gustav's analyzing faces that pass through camer-" Hiccup started explaining, but a kind of robotic voice interrupted him.

"-Sir, I have spotted Dr. Moriarty Neil, he is in the police morgue-"

"He's dead?" Hiccup, incredulous.

"-No, sir, he's talking to a detective right now-"

"Show me." he spun his chair so he was facing the monitor instead of Fishlegs, who took a seat beside him. On screen appeared the morgue, in it Dr. Moriarty Neil was analyzing the bodies left by Toothless, but Hiccup focused his attention on the short blonde girl. "Gustav, who's that?"

"-That's Detective Bog-" A file appeared on another screen, showing the picture of the blond girl with blue eyes, "-She's the new detective on the Night Fury case-"

"Why is she talking to him?" Hiccup asked, Fishlegs looked away from the camera feed and looked at the Dr.'s file.

"He's an expert in Bionic Technology, perhaps she asked him help to analyze that shotgun weapon and because the two cases are related she asked him to help again." Hiccup looked at him at with a some-what astounded expression.

"I don't understand you Fish, sometimes, your a genius and sometimes, your thicker than Snotlout." Fishlegs, seemed proud at the start of Hiccup complement, but his face turned into a frown and a scowl at the end, meanwhile something seemed to dawn on Hiccup, and turned to the monitor again "Gustav, wasn't Snotlout on my case?"

"-Yes, sir, he was, but the captain, his father, changed his case for the lack of information-"

"Dammit, this new detective seems more keen in catching me, more so then Snotlout, he never asked for help." Hiccup scowled.

On screen Moriarty shook hands with Cami and headed out the door, "Gustav, don't lose him, I need to know where he's staying." The room fell quiet has the screen changed from camera to camera, keeping track of the doctor, he entered a cab and the cameras followed it, they were both silent, patiently waiting to see where he was going, after a few more minutes he entered a ten story building. It read 'Science Research Facility', a large clearing stood in front of it, probably preparing to build something there.

"That must be where he's working." Hiccup said as the man entered the edifice.

"Are you going there right now?" Fishlegs asked, dread quite clear in his voice.

"No, I'll wait till night fall and I'll go get Toothless before I go in." Hiccup nodded to himself.

"Are you sure you should trust him?" Fish asked, playing with his hands, clearly nervous, he always was when it came to Hiccup going out as Night Fury.

"No." Hiccup told his friend.


"Alright I'll go to the sixth floor and you go to the third floor, since it's lower." Hiccup told Toothless has they stood in the clearing in front of the building Moriarty had walked into. The building had the third and sixth floor lights on.

"So what if the sixth is higher, I can jump!" Toothless honestly looked offended, and Hiccup sighed, giving in to the small raccoon.

"Fine I'll go to the third floor and you go to the sixth one." He said, clearly annoyed and opened his wings, Toothless smirked and ran across the clearing with astounding speed, jumping and grabbing onto pipes and window sills to climb up to the sixth floor, Hiccup couldn't help but feel slightly awed at the raccoons movements.

With one beat of his wings he jumped into the air and flew into a third floor open window, he walked down the hall quietly and entered the room at the end, where a man was happily humming a song and moving some plates around.

"Moriarty Neil. Raise your hands and turn around." He said with his fake voice, the man stopped humming and slowly turned around raising his hands. "Why is the Red Death here?"

"Red Death? I don't know what you're talking about." He tried to look innocent and insulted, but failed at it.

"Cut the crap, I know you're the leader's right hand." Hiccup snapped at him.

"Ah, a little raccoon told you that, ugh?" The scientist smirked and Hiccup had to wonder why.

"Just answer my question."

"Dear, Night Fury, we're here..." He paused for dramatic effect, "...For you."


Toothless walked down the lit hallway, the hook-like stock of his laser weapon around his shoulder, as he moved silently, he kept on moving until he heard and door squeak behind him, he turned around to see a large man, at least seven feet tall, and with shoulder as wide as Toothless was tall, he had dirty brown hair and brown eyes, his arms covered in bulging muscle, at least the size of Toothless' head, he was carrying several boxes.

As soon as he was fully in the corridor, he noticed Toothless and dropped the boxes, looking at Toothless in a funny way. That's when Toothless noted, he had a tattoo on his neck '79A' the Red Death marked all of their models, meaning their experiments, most didn't survive, so even though there were around 80 something models only a handful were alive. This made Toothless have conflicted feeling about attacking the man, he was just like him, an experiment, but he was one of them, a member of the people who hurt him.

Should he attack or not?

His question was answered when the giant man suddenly charged at Toothless, in a quick maneuver, the raccoon aimed his gun the head of the mutant and fired, it hit, but only seemed to leave a burn, the man stopped and ran a hand down his face.

"You hurt Gronckle, Gronckle even more angry now!" He charged again, and Toothless, likewise, shot again, but this time the man - Gronckle - didn't stop, so Toothless had to jump out of the way, almost hitting the wall on his roll.

Gronckle rocketed past him and stopped at the end of the hall, Toothless began to fire his weapon, only succeeding on getting the man more and more pissed, Gronckle grabbed one of the door frames and pulled it out of the wall, bringing some concrete with it, then he threw it at Toothless, who ducked, the door and the frame flew out the window, shattering it in the process.


Hiccup mind was in overload, so much so that he didn't notice the scientist lower his arms or hear the window shattering a few stories above.

Him. They wanted him. Why? What was so special about him? Well yea, he had powers but that didn't explain why they wanted him. Did they want his powers? That was certainly a plausible explanation.

"Why me?" He asked, his voice quiet, barely above a whisper, but Moriarty seemed to catch it.

"You see, Night Fury, you hold, in your genes, the key to fire breathing!" The doctor seemed very excited.

Hiccup realized that nobody knew the truth about his fire, he could almost laugh, they thought it was some gene mutation that made him breath fire, when in truth it was a mechanism in his throat.

"What?" Hiccup asked, he was still confused as to why they wanted him.

"We have been trying to create fire breathing humans for a long time now, and you might just be the solution were looking for." Hiccup finally snapped back to reality and just in time, too. Moriarty, in a quick move, grabbed gun from the table and fired, by instinct Hiccup covered his front with one of his wings. What a mistake that was.

Instead of a bullet the gun fired a net, which covered and pushed Hiccup to the ground so he was sitting awkwardly, it was sticky, so he couldn't really move, he also couldn't fire his blast, since his wing was still in front of his face.

"Did you know spider web is one of the world's strongest materials?" Moriarty started to say, as he grabbed a syringe, "I know, right? That material made in spiders, who would have known?"

He started walking towards Hiccup.

"Now, all I need is a little blood, and we'll be able to re-create your genes, isn't that good?"

He was about to sting Hiccup with the syringe, Hiccup knew his suit was resistant but it couldn't take bullets or stabs, that's why he used his wings for protection, why not make a new suit? Well, Hiccup didn't really have the materials, but he was seriously reconsidering that option now.

But before the syringe touched him, something entered - more like crashed - into the room.


Toothless looked back at the giant man has the window was broken, a few pieces of glass stabbed him, but his fast metabolism quickly healed his wounds and pushed the shards out of his flesh, the man's face was red, either from anger or from the blasts he had received, Toothless had no idea.

Gronckle rushed at him again, and Toothless ran to him, he jumped, landing on his back and skidding across the floor, under the mutant's legs, he shot a plasma blast to his man parts, but it seemed to do little damage, he rolled and stood, now next to the stairs.

He wondered if he should make a run for it, but decided against it for now. Instead he grabbed one of the little packages he had stolen from the lab before running away, he threw it at Gronckle who blocked it with his forearm, getting it stuck there, he tried to remove it, but it wouldn't budge, soon he became so enthralled in trying to take out the the weird box thing that it was almost comical, well, it was comical, Toothless let out a chuckle and clicked the button, it made a clicking sound and spewed out acid in every direction.

The acid seemed to have more of an effect on the brute that the laser blasts, some of it hit is face and it burned quite a bit, he now had, patches of skin missing on his arms and face, a few holes in his shirt has well with the missing skin on his torso.

He ran towards Toothless, who was still laughing and didn't notice that fast approach, has his only option he jumped to his side, into the stairs, he placed the weapon on his back and got on all fours, running down stairs and halls, when he crashed into a room

He looked up and immediately, red filled his vision, Moriarty, he thought.

"Model 83A!" The scientist shouted, overly excited.

"I will have your head." Was the only thing Toothless said - shouted - before he took a few steps forward and started firing his gun, Moriarty kept dodging the laser blasts with a grace Hiccup had never seen, he was like cat jumping from side to side, avoiding the red flashes of light.

Hiccup saw a man come into the room, and couldn't help but be awed by him, he was tall and broad, more so than his father, which was no easy feat, mind you. The man walked to the distracted Toothless and was about to grab him, "Toothless! Duck!" The raccoon heard Hiccup's shout and ducked, the hand passing just above his ears.

"Toothless! Free me!" The mammal in one swift move spun on his heel, jumped, shot the net that trapped Hiccup in an open patch, and, as he kept spinning, pierced the giant's eye with the claw of his foot, er, paw.

"Well, time to take my leave." Moriarty said, as he took off towards the door, but a smirk played on his lips. Toothless was going to follow him.

"Toothless!" Hiccup said right after he ducked a table thrown at him, "Leave him! I need you! We'll find him later!" Toothless hesitated, pain and anger evident in his eyes, "I promise!" Hiccup finished, he charged a blast in his throat, and shot, noticing it had barely any effect.

"Distract him." He heard Toothless' voice beside him, it was different than before, it was determined, strong. Hiccup nodded, the raccoon took off through the door Hiccup had walked in through, he really hoped his partner wouldn't leave him.

Gronckle charged at him, Hiccup charged a blast, this time a kill-able one, he took a little more, so when he fired the mutant was already close, in a desperate attempt to get farther away from him Hiccup beat his wings, leaping backwards and accidentally enhancing his blast's speed, this time, it hit the man and knocked him a few feet back, but he still stood.

The giant roared in anger and challenge, then used his two fists to punch the wall, creating two holes, Hiccup started shooting him with stronger blasts, but he held on, he gripped the wall through the holes, and pulled out a piece of concrete and metal frames out of the wall.

Hiccup only had enough time to widen his eyes and fold his wings around himself, until the rock, bigger than him, bigger than Gronckle himself, hit him.

The piece of wall kept going, Hiccup flushed against it's front, it collided with a wall and broke through it, sending Hiccup and the rock out of the third floor into the clearing in front of the building.


Toothless heard the roar, Gronckle he presumed, the explosions, which he assumed Night Fury had made and moments later the two loud crashes, the last two worried him.

So he finished planting the last 'Acid Sprayer' has he called it, and ran up the floor, as soon as he came close to a window, he was terrified, a large boulder, with iron rods sticking out laid on the clearing, but that wasn't what made him afraid, it was the body laying in front of it, wings covering his torso and face, the boulder laying on top of his legs.

He broke the window and jumped out, landing neatly on the balls of his feet, and rushed to the boulder, but before he moved it, he turned back to the building, he clicked the button and after a few moments the building collapsed on it self, the acid doing wonders to edifice foundations and with any luck the Gronckle was dead. He turned back to the boulder and tried to move it but it was hard, even with his enhanced strength, he barely moved it an inch, so he grabbed his gun and shot the boulder, making a cloud of dust rise. He cleared away the now small, lighter pieces.

He was astounded when he found him still awake, and he knew one thing. This man was strong, more so than normal people.

"Astrid... take...me...to...Astrid..." And he passed out

The sight was discussing but he had seen worst if he spoke the truth, mainly because he had caused it, Night Fury lay on the floor, his left lower leg completely crushed, he grabbed the part under his knee that wasn't crushed and pressed hard, he ripped a part of his suit and enveloped the bleeding stump.

Then he heard it, a small noise, barely above a whisper. Beep, Beep, Beep.

He followed the noise with his keen hearing, only to take a few steps and stop on the side of Night Fury's head, he removed he mask, and was surprised to find such a young man, he had been expecting a guy in his forties, not twenties.

He located the beeping in his ear and grabbed the small device it was a small nub barely bigger than a thumb nail, it was beeping and flashing green, he placed in his hear, and clicked the light.

"Hello?" He said, felling kind of crazy talking to himself.

"Who's this? Where's Hiccup?" The squeaky, but male, voice asked from the other side.

"I don't know a Hiccup but I retrieved this from Night Fury. He's injured." He said mater-of-factually.

"Injured!?" The man squealed.

"Pretty bad too. He was mumbling something about taking him to a... Astrid? Or something." He said in the same tone, trying to hide his slight worry.

"Why would he... Oh, she must have medical training! Gustav! Gustav, take control of Hiccup's wings and take him to his home, NOW!" Toothless heard a kind of robotic voice answer on the other side. "Toothless, thank you, if you want to go with him, you need to get on his back now."

Toothless looked to see Night Fury was now standing, kind of, his wings were beating lightly to keep him a float, Toothless, without thinking, jumped onto his back, grabbing his shoulders, "Go."

They flew above the city, and Toothless' eyes widened with wonder and awe at the sight, he was delighted, flying was... amazing, was the only word he could use to describe it.

They entered a pipe above a lake, and the smell of rot and dirt entered Toothless' stronger sense of smell, Gustav lead them across the sewer and into an opening on the roof, they entered a room with a car and tools sprawled about, Toothless jumped down grabbing Hiccup and laying him on a table, he heard a door click and drew his gun, only to come face to face with a chubby blonde boy.

"Toothless! It's me you spoke with me!" The squealed again and Toothless recognized the voice and lowered his gun.

"What now?" Toothless asked.

The boy sighed, "Now this. ASTRID!" he shouted the last part, the name Toothless had heard Night Fury telling him to take him to. A blonde girl came rushing down the stairs, in her pajamas, gun in hand, she flicked on the light and yelped at seeing Toothless. "Astrid, Hiccup needs help, now!" The blond boy had tears in his eyes.

Astrid face turned into worried at the mention of Hiccup needing help. They must be mates, was Toothless first thought but he pushed it back, it wasn't important now.

What was important was to help this Astrid girl save Hiccup so Toothless could have his revenge on the Red Death, and deep down, Toothless didn't want to lose his first friend.


It was still night has Moriarty walked across the clearing towards what used to be his building, he could hear whimpers coming from the scene of the downed edifice.

As he closed in he saw the source of the whimpers, Gronckle, completely trapped under what was probably tons of concrete.

"Brother, Gronckle needs help!" He waved his hands around, his body was full of scrapes, and even some scratches, which was no easy thing, his eyes were glassy, holding back tears.

"I will help Gronckle, but first swallow this." The scientist grabbed a vial from his pocket, filled with white dust, and Gronckle opened his mouth, Moriarty poured the dust into his mouth and told him to swallow, which he did.

In a matter of moments the mutant was dead, foaming out of his mouth. The doctor smirked evilly grabbing his phone and dialing a number.

"Bring me Model 37A, code name: Nadder."


Sorry this chapter is later, slight writers block and finals keeping me occupied, however this is the second longest chapter in this story and had more action, so I hope it was worth the waiting.

Also please tell me what you thought about the fight scene, I hope it wasn't too confusing or anything.

I hope you enjoyed and have good day!
