Welcome to my new story Double Sided, every person has two sides to them, a good side and a bad side. Dragons are much better at locking away their bad sides, and Toothless is no exception. But what happens when late one night, Hiccup manages to piss Toothless off enough to make him snap.

Chapter 1: The Breaking


Toothless knew his bad side was the worst part of him, he would only physically see his bad side when he was having a nightmare. And even then it didn't last long.

But on this day, Toothless was scared. Scared of himself. For you see, he had a nightmare the very night before, and his bad side had said something that would forever haunt Toothless until the end of time itself.


Toothless found himself standing in a world where there is no stars or sun, and where the ground was pure flat and had fog covering each and every square inch of it.

"Oh great, here we go. Time to see Nightmare Toothless" Toothless said to himself and shook his head with a chuckle, he figured it would be as easy as all the nights before. But he would soon find himself to be wrong.

Toothless turned around when he heard a deep evil chuckle, he turned around and saw IT, his evil side. His evil side had a completely different personality and looked different, his evil side or Nightmare Toothless was a bit taller and had red eyes instead of green, otherwise, they looked the exact same.

"Well well well, if it isn't you, Toothless. The same person who LOCKED ME UP IN THE BACK OF YOUR MIND!" Nightmare Toothless screeched and swiped to claw at Toothless, except Nightmare Toothless' paw just went through Toothless because this was a Nightmare. Nightmare Toothless takes a minute to calm himself down before starting with a smirk.

"And now...I'm gonna get my revenge" He comments and Toothless laughs, playing it off as just being more nightmares.

"By what? Haunting me for the rest of my life, I'm not scared of you. I know that in a minute I'll wake up in the land of the living and not have to see you until the next night" Toothless said and Nightmare Toothless laughed hysterically.

"That's not what I'm gonna do. For you see, i will find a way to either get control of your body or get an entirely separate body from yours, and then I'll kill each and every last one of the dragons and Vikings on Berk, saving Hiccup until last so i can tear his still beating heart out and then tear him to shreds! And then I'll burn him to a crisp and eat him! All while you'll be screaming in pure agony as everyone and everything you've ever known or loved WILL BE DESTROY BY ME!" Nightmare Toothless yelled and then smirked as he looked at Toothless' horrified and scared face.

"Y-You wouldn't! Y-Y-You can't!" Toothless says horrified at what the other guy was saying.

"Oh, but i can! All i have to do is wait until you get angry enough and then...pop, i come out!" Nightmare Toothless says with a smirk that would send even Stoick the Vast running.

"Then I'll just...i'll just end my life so you can't end the lives of everyone on Berk. 1 Dragon for nearly 600 lives, i think that's a good trade" Toothless says with a bit of confidence. But then Nightmare Toothless smirks harder.

"Oh, but you see. That's the beauty of it! Your survival instinct is too strong! Even if you tried to jump off a cliff, your precious Hiccup would save you at the last minute, and if you tried to slit your own throat, your instincts would stop you. So all i have to do is wait, and then i can destroy everything you love! HAHAHAHAHAHA..." Nightmare Toothless laughs and then everything goes dark.


Toothless jumps awake on his nice dragon bed, he's practically shaking at this point with fear. He looks around the room and spots Hiccup sleeping peacefully on the other side of the room.

Toothless remembers what he said, about ending his existence to save everyone else. He slowly raises his claw up to his throat and try's his hardest to press down into his scales. But he feels something come over him as soon as a little pressure is put on his throat, his arm goes limp and he whimpers, he can't even save Hiccup that way.

Toothless then realized something, if all it took was for him to get mad for Nightmare Toothless to come out, all he had to do was keep calm for the rest of his life. That shouldn't be too hard, Toothless has only ever been angry once or twice in the nearly 17 years he's been alive. It shouldn't be too hard to control his emotions.


At the end of the first day, Toothless was quite happy with himself, he had managed to protect Hiccup from himself perfectly. Now all he needed to do is repeat this for the rest of his life, shouldn't be too hard? Right?

Toothless walked into the Haddock House, it was around time for dinner and he was starving.

He then noticed that Hiccup wasn't as happy as usual, Toothless approached him concerned and sniffed him, that's when he smelled blood and Toothless had to keep himself from getting angry.

"Ooo, Toothless...umm, well, Snotlout may have accidentally stabbed me in the arm when we were training in the forest," Hiccup said and Toothless felt his anger rise a lot, but he caught it just in time and took a few deep breaths in order to keep himself calm.

"Its ok bud, Snotlout apologized, shocking i know, and even bandaged my wound" Hiccup commented and Toothless felt his anger go down majorly, he was far more happy that at least Snotlout had made up for it and apologized.

They went on with the day perfectly, until Hiccup made the fatal mistake of accidentally putting an eel on the floor right next to Toothless. Toothless panicked and quickly started running around, his anger started building to intense levels, Toothless then shot a plasma blast at the eel and felt his anger hit boiling point until something in his head snapped.

That's when Toothless imminently went from burn the eel to freak out. He had gotten too scared and angry, and know he was gonna pay the price.

Suddenly, for Toothless, everything went black.


Hiccup looked down at Toothless, who had collapsed out of nowhere.

"Oh, gods! Toothless! Buddy! Are you ok!" Hiccup yelled and started shaking Toothless frantically, that's when Toothless opened his eyes and stood up straight, except he wasn't leaning to his right like he normally did, and his ear flaps were pressed against his neck.

That's when Hiccup caught sight of Toothless' eyes, they were not green...they were red.

"T-T-Toothless?" Hiccup asked cautiously, worried at what was going on.

"O-Oh H-Hell-Hello Hicc-cup," Toothless said in Norse-somehow-and it was garbled and slurred and stuttering.

"Toothless?" Hiccup asks and reaches a handout, determined to figure out what is going on.

"O-Oh, I a-am not T-Toothless, i a-am Night-Nightmare To-Toothless. Toothless' e-evil side t-that y-your best f-friend, Toothless, d-dreads with a pass-passion" Nightmare Toothless says and starts cornering Hiccup. Hiccup feels his body start shaking with fear and he starts backing up.

"T-Toothless doesn't have an evil side! He is as pure as the air and the water and just all around good!" Hiccup says and Nightmare Toothless laughs in a garbled voice.

"E-Everyone has an e-evil side, e-even you Hiccup. T-Toothless j-just lock his a-away VERY w-well! B-but now i-i am free! And I'm gonna kill YOU!" Nightmare Toothless says and then charges Hiccup, he raises a claw and is about to bring it down on Hiccup and kill him. But for some reason, an unseen force takes over his arms and legs and forces him to back off.

"WHAT? T-Toothless must ss-still have a b-bit of c-control over this form. i n-need another!" Nightmare Toothless screech and then uses a plasma blast to blow a hole open in the Haddock house, he then runs off into the night. Leaving Hiccup scared and alone.


Nightmare Toothless run around the entire island of Berk, he even ate some sheep whole. He then stopped outside of a lone hut on the other side of the island.

"W-Where will i-i find another b-body!" Nightmare Toothless yells and then Mildew comes running up.

"What are you doing here dragon! Get out of here before i turn you into clothes!" Mildew yells and waves a sheep around.

"NO ONE TELLS ME WHAT TO DO! Anyways, do you know where i can find a body so i can kill Hiccup" Nightmare Toothless says in perfect Norse, his speech problem now fixed.

"Why would you, Hiccup's 'best friend', want to kill him. And why would you need a new body dragon, you already have one!" Mildew says while raising an eyebrow.

"I am not Hiccup's best friend, Hiccup's best friend is locked away inside this form. I am Toothless' evil side and i have control over this form, but that blasted Night Fury still has a bit of control of this form. Meaning that i can't kill Hiccup" Nightmare Toothless explains and Mildew smirks, he has a way to get rid of the dragons!

"Let's say with magic i could provide you with a form, a form that you would use to kill all the dragons on Berk and Hiccup. Would you let me give you a form?" Mildew says, believing that he was gonna win. Nightmare Toothless smiled sadistically and evilly.

"Yes, do it now," Nightmare Toothless says and Mildew smiles, he has been practicing magic for months now and was ready to create a form for Nightmare Toothless.

Mildew used a few waves of his staff and some accident words to separate Toothless and Nightmare Toothless, Nightmare Toothless had the same body he had in the dream world, except now it was real and physical.

"Thanks, but I'm afraid i have to announce an extra part of the plan," Nightmare Toothless says and then bites down on Mildew, he quickly kills and eats Mildew before turning to Toothless, who is still knocked out.

"Time to end your life, Toothless!" Nightmare Toothless announces and then was right about to attack when suddenly the sun came up, he had wasted so much time wandering about Berk that the entire night had passed! Nightmare Toothless then felt himself become non-physical, he tried to attack Toothless but found that he couldn't touch him.

"Damn it! I'll have to wait until tonight!" Nightmare Toothless says and feels himself fade away to an empty void where he will wait until tonight, then he can attack Toothless and Hiccup and finally kill them.


The first thing Toothless felt was that he was lying on his side and that his entire body was freezing cold. He opened his eyes and looked around, he was by Mildews house! Why was he there?

Toothless got up and then realized that something was different, he wasn't hungry and his entire body was sore like someone had run him into many trees.

Then he remembered that Nightmare Toothless had token control, and he freaked out considering that he had an overstuffed belly. He felt around his stomach just in case and had a sigh of relief when he only felt sheep.

"That's good...wait...I'm talking!" Toothless says and then falls onto his back, he manages to get back up and he searches for Mildew, he finds no trace of the old man except for his staff and his pet sheep, fungus.

"I need to see if Hiccup is alright, he may not have eaten him using my body but he could have done other things to him!" Toothless yells and then full on sprints to the Haddock House, he makes it there in under a minute and finds that the entire front of the house has been replacing, he also sees some burnt wood off to the side. The wood smells of plasma fire.

"Did he do this?" Toothless mumbles to himself, trying his best to keep his new found voice down. He then pushes the door to the Haddock House open and he makes his way up the stairs to find Hiccup drawing at his desk, shaking. Toothless felt instant relief, Hiccup was alive and just fine.

Toothless slowly but surely walked over to Hiccup, and about halfway there he stepped on a creaky floorboard and Hiccup turned around immediately. The second Hiccup saw Toothless he freaked out and ran into a corner.

"N-No! Please! D-Don't!" Hiccup yelled and covered his face with his hands, Toothless felt guilty as all hell. If he hadn't gotten angry, then Nightmare Toothless wouldn't have been able to scare Hiccup this badly.

"H-Hiccup" Toothless moans and approaches Hiccup slowly. Hiccup recognized the voice, it was really similar to the one of Nightmare Toothless, except for two differences. Nightmare Toothless' voice was as deep as can be, and Nightmare Toothless always sounded crazy. This voice sounded calm and a bit more normal then Nightmare Toothless.

Hiccup slowly peaked out from behind his arms and saw that Toothless' eyes are green, not the red they where. Hiccup imminently felt safer.

"T-Toothless? Is that you?" Hiccup asked scared, he reached one arm out. He just wanted his best friend to come and comfort him. Toothless slowly but surely came over and nuzzled Hiccup sadly.

"It's me, Hiccup. It's me. I'm not going anywhere, and i promise that what happened last night will never happen again" Toothless whimpered and nuzzled Hiccup, Hiccup wrapped his arms around Toothless and cried.

"H-How are you talking, w-what happened last night...i...i don't..." Hiccup tries to talk but Toothless shushes him. Toothless carries Hiccup over to his dragon bed and they both lay down on it, Hiccup curled up against Toothless' belly and chest. Hiccup also noticed how stuffed Toothless seamed.

"W-what did you eat?" Hiccup asks and Toothless lets out a sigh.

"Well, the other guy took control of my body and ate a bunch of sheep. I mean seriously! He should know sheep takes the longest for me to digest! After all, he has all my memory's! Anyway's, i should probably start from the beginning" Toothless says and then retells the events of the past 1-3 days in full detail. Hiccup lays his head on Toothless' paw, uses Toothless' chest and belly as a bed, and Toothless' wing as a blanket.

"Hiccup, I'm so sorry for what happened. I shouldn't have gotten angry because of the eel. If i hadn't, everything would be fine" Toothless moans and lays his head next to Hiccup's head.

"Its, it's ok bud. We all make mistakes, we just have to make up for them. Come on, i bet you're pretty tired and you want to sleep off all those sheep" Hiccup states and Toothless nods, they both fall into a deep, peaceful sleep.

Except Toothless was freaking out inside his mind because Nightmare Toothless wasn't inside his head anymore. And that could only mean one thing, that Nightmare Toothless now had a body of his own and would come after Hiccup and him, it took a while but Toothless eventually stopped panicking. But it did take awhile.


That's the end of Chapter 1! Chapter 2: The Nightmare Night will be up sometime soon. The Nightmare Night will see Hiccup and Toothless up at night and battling against Nightmare Toothless. This story was actually inspired by another story on this site, i just can't remember the name of it.

Anyways, this is JustANormalHTTYDFan, over and out.
