(A/N) Got this crazy and most likely awful idea wile listening to the song Demons by imagine dragons.

Story idea timeline: Takes place in Riders and Defenders of Berk.

Bill cypher: I like the idea and will do it, except the meeting Thor and Loki thing because I don't know much about them.

phieillydinyia: I really love that your liking my story. Your reviews make my day.

Story idea: What if Hiccup had A dark side to him? What if Hiccup had some dark stuff hidden in the very back of his mind, and secret powers he never told anyone about that he got after the red death? In this story Hiccup tries to control the darkness in him and use his power for good, but it get's hard and he'll need his friends help.

Warnings/details: Rated K+ For some violence, and injuries. Mild Hiccstrid. Hiccup with powers.

Also!

Hiccup and the other riders look like they do in Riders and Defenders of Berk, Hiccup and Astrid are A sort of couple, and when Hiccup's darker side starts taking over the forest green in his eyes will have some faded red in them wile strength will become much more than normal.

Summery:

Hiccup and Astrid are out racing one night, and decide to land on A part of the island to take A break. Hiccup has A darker source of power within himself that's becoming harder for him to control. How will Astrid and everyone else react to this hidden side of Hiccup, this demon within? Can they help him? Or will Hiccup be forced to isolate himself like when he was younger all over again to protect his friends?

"Shh, what was that?" Hiccup asked. Him and Astrid had decided to land on A part of the island near the forest after night racing. "I don't know." Astrid replied, holding her axe. Suddenly A large wolf pounced on her out of the bushes, and Astrid wasn't expecting it. She was pinned under the wolf, and Hiccup became terrified.

Take it out. Don't let it hurt her. Destroy the beast! The darker force inside of Hiccup yelled. Normally Hiccup would keep it hidden, not listening to it. He'd had to ever since his normal small voice in the back of his head he'd had since he was little became worse after the red death when he started developing strange powers to go with it. No one knew about it.

"Hiccup!" Astrid shouted, kicking at the wolf. The dragons had run off A few minutes ago. They wouldn't make it back in time to help her! Hiccup had to help. "Leave her alone!" Hiccup shouted as anger filled him at the animal attacking his best friend maybe more. A faded red-ish color mixed with Hiccup's forest green eyes, and Hiccup started feeling disoriented. He lifted his hand, A fire raging thorough his veins causing a lot of pain. The fire shot out of his palm, killing the wolf instantly.

Hiccup's eyes went back to normal, and he suddenly felt like throwing up and dizzy. Astrid was shocked by what she just saw, but ran up to Hiccup, catching him when he fell. Hiccup looked exhausted and he opened his eyes slightly to look at Astrid who was holding him. "A-Astrid?" "Hiccup how did you do that?" Astrid asked. Hiccup closed his eyes and shook his head. "I don't know. There's been something in me that's giving me the power to do those things for quiet some time though. I didn't tell anyone because it's been trying to control me and I didn't want to scare you guys away. It's been getting stronger though." Hiccup grabbed his chest witch had A burning sensation in it.

"Hey it's okay, I'm not gonna run away Hiccup." Astrid looked up and see Stormfly and Toothless running up to them. They looked disoriented and overly calm. They were probably in dragon nip but heard there riders yell. Toothless sniffed Hiccup, and began growling. Astrid looked confused. "I think Toothless is able to sense it." Hiccup said in A quiet voice. How long had he been going thorough this? It was all extremely confusing but Astrid had heard of people with powers like this in tales and stuff, just never believed them to be true. Not until now that is.

...

Hiccup woke up the next morning in his bed. He tried to sit up, but his hands were tied to his bed. "What the?" Hiccup looked at his arms and realized he had bandages on them. Why did you tell someone about me and not kill them for it? That voice Hiccup had said, but Hiccup ignored it. "Shut up." He whispered to it.

Hiccup suddenly heard foot steps before Astrid came thorough his bed room door. "Hey Hiccup." Astrid looked at him with A sad face. "Astrid why..." Hiccup tried to move his arms. "You don't remember?" Hiccup shook his head. "Hiccup last night you started having nightmares and you thrashed around in your sleep. That source of power you said you had must have gotten worse because in the nightmares you tried to claw at your arms with your hands in your sleep." Astrid explained, brushing A strand of hair out of Hiccup's face.

"I don't even remember having Nightmares or thrashing against anyone. Maybe I hit my head on something." Hiccup said to no one in particular, sounding confused. "Well now that your awake, I'm sure no one will mind me helping you get your hands out of those ropes." Hiccup nodded, smiling gratefully.

Astrid untied him, and Hiccup sat up. "What do you say we go to the academy?" Hiccup asked. "Actually Gothi came over. She said with the dark energy powers you have and with your episode last night, along with your wounds, she wants you to rest until she can do more research. It's an order." Astrid said sternly. Hiccup sighed and nodded.

Don't listen to her! Don't you know I could easily help you push her aside and get us out of here? Hiccup tried to ignore the voice, but then something in his skin made his wounds under the bandages start burning. "Gah!" Hiccup shouted, grabbing his arm. "Hiccup! Hey what's wrong? Talk to me." Hiccup's breathing was harsh, and when Astrid looked she could see his forest green eyes mix with A sort of dark red color, and his skin grow pale.

"Hiccup common tell me how I can help." Hiccup shook his head biting his lip wile trying to stop the pain in his arms. "You can't help Astrid. I'll be fine." Hiccup hissed in pain, his chest becoming tight. Everything started feeling like he was spinning, and his head hurt like Hell. You'll come around. Hiccup heard an evil voice snicker, before he finally fell unconscious.

...

"Hiccup? Hiccup!" Hiccup woke up wile pouring in sweat. His dad was standing over him, shaking his shoulders. His arms were tied down again, and Hiccup didn't even bother asking. Hiccup opened his eyes, seeing his dad looking at him worried.

"What happened?" Hiccup asked. He looked out his window realizing it was night. "You seemed like you were having A night mare, then you couldn't breath." Stoick said, feeling his son and realizing he had A fever. "Oh. How long have I been out?" Hiccup asked, tugging at the ropes on his wrists but unable to break free. "All day. You fell unconscious when Astrid was here. You wouldn't wake up until now." Stoick explained, taking his sons hand.

Hiccup's expression suddenly looked upset. "Dad...do you know about-" "Yes Hiccup. Gothi's doing the research to figure out something to do. There have been other things like this in legends and tales of other villages, and she say's she's even seen it before. Until we can figure out how to help you need to stay inside and rest." Stoick lay A hand on Hiccup's shoulder.

"Dad...What if there's not something Gothi can do? This...thing in me it-it's been trying to get to me for A wile. After the red death it's been A living nightmare. I don't what I'd do if-" "You won't hurt anyone Hiccup. Gothi's seen what an evil source can do and we're doing all we can to keep you and everyone else safe." Stoick gestured to Hiccup's hands tied to the bed. Hiccup sighed, the ropes rubbing his wrists. "Was I clawing at my arms again?" Stoick nodded and Hiccup went quiet.

"I made dinner. Want to come downstairs to eat or are you to tired?" Hiccup looked up. "I'll come down." No you won't. Hiccup flinched at hearing it. Not this again. Stoick grabbed Hiccup's wrist, but pulled back as his skin burned him. "No dad...d-don't." Hiccup said, moving his hand back. Stoick obeyed, laying A hand on Hiccup's head. He was running A really high fever and pouring in sweat. Hiccup groaned as A wave of pain hit his head and arms.

See what I can do? Hiccup shook his head and bit his lip. He tried to fight it off. He tried to make the surge of power he felt in himself go down. Stoick tried to comfort his son but everything was muffled to Hiccup's ears. Would you stop fighting me?! "Never." Hiccup whispered as the voice spoke. Suddenly he felt A pain in his stomach, and it literally felt as if he'd been stabbed. Hiccup shouted in pain, his vision clouding with red, then black, and he was out.

"Hiccup!" Stoick shook Hiccup but the boy wouldn't wake up. Stoick removed Hiccup's shirt and long pants but left shorts on him before pulling A blanket over him up to the center of his torso and using A wet cloth to try and break his sons fever. In the process, he saw A deep burn mark on Hiccup's stomach that was throbbing as if he'd just been attacked. Hiccup was fighting A demon inside of him, and Stoick felt helpless.

...

The next morning, Hiccup woke up with A headache. Hey sleepy head. Hiccup groaned. "Can't you just knock me unconscious again and be done with it?" Hiccup asked. Nope. If you really wanted me to stop you'd do what I say. You know your going to starve to death at this rate. Hiccup frowned. He was sick of this. It had been going on for to long, and got way worse after he saved Astrid. "Then why don't you just kill me now if you want me dead?" Hiccup heard no response, and realized his words must have been confusing to the force.

"Maybe I should say something like that more often." Hiccup sighed. Toothless, who had been kept downstairs the day before because he got mad that Hiccup was tied down and yelling in his sleep, thinking one of the villagers were the ones who hurt him, walked up to his rider. "Hey Toothless." Hiccup smiled as Toothless licked his hand and wound in his stomach. The Night Fury healing saliva and cool touch really helped. "I'm glad I've got your help bud." Hiccup scratched Toothless' scales.

A little wile later Stoick came home and gave Hiccup lunch. The boy was still tied down and really didn't mind. It was better than fighting with his 'inner demon'. "Thanks dad." Stoick untied Hiccup's wrists so he could eat. Hiccup was surprised his evil side didn't attack. Maybe it was worn down? "Hiccup, I'm really worried about you. If you need anything or are hurting, you tell Toothless to come find me okay? Astrid said she'd come over after training." Hiccup nodded and suddenly felt sick after eating. He knew exactly who's fault it was to.

"Uhm dad?" Stoick looked at Hiccup before he could leave. "I think it would be wise to redo the ropes, just in case if I fall asleep and you know." Stoick nodded and did as told. He didn't like the fact Hiccup was scared something would happen, but he knew nothing about this thing taking over Hiccup. Hiccup though, knew it all to well.

...

A little bit later Astrid walked into Hiccup's home. "Hey Hiccup. How are you feeling?" Hiccup propped himself up on his elbows since his forearms were strapped down, and smiled at Astrid. "I'm fine. Been running A bit of A fever." Hiccup gesture best he could with his hand at his bare torso that was red, sweating, and had A burn on it. "But other than that I'm fine." Astrid smiled and sat by Hiccup, feeling his skin and realizing his fever was really high.

"Here, you need to try and break your fever." Astrid pushed Hiccup down against the bed and used the cold cloth on his forehead. "Astrid you have-" Hiccup was cut off as the cool cloth was comfort to his burning skin and he sighed. "It's fine Hiccup. I want to help you as much as I can. You'd do the same for me." Hiccup nodded in agreement with that last part. He would always protect Astrid. Somehow, his skin felt less hot as he thought about protecting her.

"What the...How is your skin already cooling down?" Astrid asked. "I don't think the fevers because I'm sick Astrid. I think it's...you know." Astrid nodded in understanding. "What do you think cooled it down?" Hiccup shrugged. Astrid ran her fingers thorough Hiccup's hair, and Hiccup leaned into her touch as her hand reached his cheek. His skin cooled off more and another voice Hiccup wasn't used to spoke up. Protect her with your life. It felt like some sort of an instinct, and it felt weird to have another voice in his head. I really am crazy aren't I? Hiccup thought to himself.

Perhaps. Hiccup flinched as that darker voice came into play. He saw Astrid look worried as she felt his hand witch became hot. He remembered what the other voice had said, and tried to pull back. "Astrid move!" Astrid moved and that same fire that shot the wolf encased his hand. Hiccup became exhausted, but held on. He found out, as he held on and focused on the fire, that he could actually control it. No! Stop! Hiccup smiled as he realized that demonic voice was trying to keep this A secret.

"Hiccup! D-Does it hurt?" Astrid reached towards his hand but Hiccup pulled back, and he shook his head. "It hurt like Helheim at first, but now it's more of A numb feeling and not in A bad way. I can actually...control it. Here remove these ropes and I'll show you." Astrid nodded and removed the ropes. Hiccup sat up, and he was right, the fire moved with his hand and is was like he was bending it to his will. "Wow! Hiccup that's incredible!" Astrid watched it in absolute wonder. She'd never seen A person who could control fire before.

Toothless stood by Hiccup, watching the fire. Suddenly it started getting bigger and Hiccup looked scared. "Uh but I don't think-" Toothless cut him off. He blew on Hiccup's hand until the fire went out, and there wasn't even A red mark saying it was once there. "Wow, thanks bud." These are things you can do when you put your mind to it. You're demon within will try to control you, but if you don't let it, then you will have this power. Hiccup smiled as that more gentle voice spoke up. Suddenly he started feeling drained.

"Augh, apparently it has side effects though." Hiccup held his head and Toothless supported him. "You've been thorough A lot of confusing stuff Hiccup. Get some rest and I'll be right here." Astrid lightly kissed Hiccup's fore head who fell into A deep sleep moments later.

...

Later that day, Hiccup woke up to the sound of A dragon roar. He sat up and heard Astrid yell after something fell. "Astrid!" He shouted after Toothless stood up, looking worried. "Common bud, help me get out of these." Toothless bit Hiccups ropes and they both jumped out the window. Astrid was pinned under A monstrous Nightmare near the forest and no one was around other than Hiccup's dad and Fishlegs who were trapped under A few fallen tree's.

"Astrid, Fishlegs, dad!" Hiccup shouted for them and ran over to them. The Nightmare shot at Hiccup who dodged the blast with surprising speed. He then used the fire he could bend and shot at the Nightmares feat. The Nightmare moved, eyes full of confusion, and roared before flying away. Hiccup then ran to his dad and Fishlegs who were still trapped, and tried to move the tree's. At first he couldn't but then his fingers bent an odd way, causing them to look like claws.

This helped him get A grip, and Hiccup moved the tree's after Toothless used all his strength to push them up, Hiccup having to push them forward so they didn't just cause the pile of tree's to become more dangerous and fall over. "Hiccup. How did you do that?" Stoick asked, putting an arm around his son.

"I don't know. I always though I could only do it when I was mad, but now I can control fire like that without it getting dangerous, just so long as Toothless is there to put it out." Hiccup held his flaming hand in front of Toothless who blew it out. "You know, that could really become useful." Astrid said and Hiccup smiled. "Just as long as you guys keep me from getting hurt." And they will. i'll help to. The good voice said and Hiccup smiled having A good feeling about this.

He only rarely heard the demon voice after that, and his skills with elements improved greatly. Hiccup was glad he had his friends, didn't have to isolate himself, and had Toothless when his skills got to hard to handle.

(A/N) I know, I know. This was short, rushed, weird, but I had writers block and was listening to music when Demons by imagine dragons came on. Then demons by starset and this was the only idea I had and I needed to write SOMETHING. So if you do comment, know I already know all these things so don't need hate mail even though I deserve it more than anything. Your amazing, and please review.

Until next time fellow dragon riders, Plasma Snow piece out.
