Chapter 12 people, here it is to ease off your suspense. Just to explain, when you see Hiccup's name like that: Hiccup" the it's with him normal. But if it's in bold, it's him as the bad dragon...soooo without any interruption, enjoy (well try to) ;)

"W-what...Wait, I helped you.." Magness began, backing away from Hiccup who was now the Fanged Fury.

"Yes you did, but last year when you were tesing out this vessel for me...You nearly got rid of it in one move...If it wasn't for the three signs of heart, you would have failed on getting my vessel..." Hiccup growled with his dark monstrous voice, walking closer to the old man who was backing away.

"B-but that boy, he chose to kill himself that time," Magness tried to reason, but Hiccup ignored him, changing into a deadly nadder with one glow! "Yes but if you hadn't over done the whole testing, then we might have not have to end it like this.."

"Did Hiccup just..." Astrid began, until Alvin explained he legend to her.

"The Fanged Fury...One of the most legendary dragons I've ever studied about back in the day. It was said that this demon can talk and transform into any dragon species, either extinct or alive...The Fanged Fury will also possess the abilities of the dragon he turned into." "But there was only one species of the Fanged Fury, and it was killed by the king of dragons, another legend.."

"If he could change into any dragon...Oh thor, he's not going to.." Fishlegs gasped, getting a sick feeling on what Hiccup was planning on doing.

"Let's see if you can dodge these poisonous spikes, at ultimate speed!" Hiccup laughed, sending his spikes down like a hard sorm while Magnus dodged almost all of them, while some made an exit for him to get out of the cave.

One of the spikes hit his right shoulder, causing the poison in that spike to spread through his arm while he covered the wound. The others followed, seeing this scene unfold, unwilling to believe that Hiccup would try to kill someone...Especially Hiccup.

"That was too easy for you old man...Oh, you look dirty, how about I help wash out that dirt!" Hiccup then went from a Nadder, to a Scauldron!

Magnus only had less than five seconds to step aside before Hiccup blasted a maxium amount of boiling water, but some of the wate burned the old man's left arm, causing it to bleed.

Stoick couldn't believe his eyes, he tried to step in front of Hiccup but the scauldron then turned into a flight mare! He flew everywhere, paralyzing everyone with the frozen mist, even Magness. He was about to strike down at Magness but was distracted by Toothless,shooting plasma blasts since he forgot to freeze the dragons!

Hiccup, aggravated, the froze Toothless but the others were already unfrozen so he turned into a whispering death, digging underground, blocking everyone's way, including the dragons!

"Hiccup!" "Stop...STOP IT RIGHT NOW, THIS ISN'T THE REAL YOU!" Astrid screamed, trying to still get to Hiccup, but he keep digging down and resurfacing, throwing rock spikes all over the place.

He then threw some to pin Magness to the ground while the old man struggled, scared for the first time in his life! "No you will die!" Hiccup then threw some spikes all over the old man's body, causing him to scream bloody murder! He was about to fire but then he felt a strong force pull him down a bit. "What!?" "What's happening to me..."

"Looks like we've...both been betrayed...You see...Two drops of he lad's blood fell in the lava...So that gives you a time limit...A limit of ten minutes...until the real Hiccup takes over his new body." Magness coughed out some blood, smiling at least. "Once Hiccup takes control, you'll have to wait until the next day and there you'll choose when to strike back, skip a day and you'll get an extra ten minutes for each day you skipped..."

"However, the lad can still fight his way out of your control, but only having five minutes of your time before you take control again." "But not now..."

"Only three more minutes...Choose wisely.."

(WARNING: This part includes some bloody moments...)

Infuriated in a million ways, Hiccup made a loud gruesome banshee like roar before turning into a monstrous nightmare, and clawing Magness to his death. "DIE!"

Each swing, more blood flew from Magness's body, while Hiccup keep using his claws with such force.

Fishlegs fainted to the ground along with Snotlout and the twins, since they've never seen so much blood since the days they used to kill dragons.

Stoick couldn't believe what he was witnessing...Hiccup, his own son...Committing murder...No, this isn't Hiccup, the murderer is the Fanged Fury, not Hiccup, my son.

Hiccup kept changing into every dragon with strong, sharp talons every second. From a typhoonerang, whispering death, gronckle, to a timberjack! Drops of blood fell on to his tunic, while his crimson eyes fired in fury. For the finale, he turned into the Red Death, causing everyone to back away, and he fired down at the dead body, leaving nothing but ashes and a helmet...

Finally he stopped while he held his head, shaking it until he back into the half human half dragon with his eyes back to being forest green. "What happened..." Hiccup looked up, seeing his friends, and their dragons stare at him petrified except for Stoick and Toothless, who looked at him in worry.

Hiccup looked to the right, and saw ashes and blood all over the place, along with Magness's helmet...Beginning to tremble violently, he slowly looked down at himself, at his dragon paws...

His tunic was covered in bits of blood, and his claws were full of the old man's blood. "No...I didn't...How could I..."

You killed Magness Hiccup, you are a murderer...A dark voice whispered through his mind. "No..." Hiccup then realized that it was true, the evidence was as clear as a bell, no wonder everyone is backing away from him.

His eyes were shaking, as he just sat there, staring at the burnt spot, never noticing someone approaching him until he felt someone touch his shoulder. Alarmed, Hiccup growled at the intruder, stopping only to realize that it was Toothless...And his father.

"Hiccup, calm down...We'll figure this out together and then.."

"NO!" "GET AWAY FROM ME!" Hiccup interrupted, pushing both father and friend back, confusing the two. "Just go away!" "Go!" "If I come stay with you then I'll end up killing you...without even knowing.." He then got up, looking down sadly. "I'm no longer you're son Stoick, I'm just a murderous demon...A monster..."

Stoick couldn't believe his son's words, he didn't want Hiccup to be afraid of himself, not in a million years.

"Just stay away...Don't come after me or anything!" "I have to leave!" Hiccup then turned himself into a night fury, and quickly ran off, but Stoick and Toothless ran after him.

"No Hiccup come back!"

Stoick touched his shoulder before Hiccup roughly pushed them both back, shooting two plasma blasts.."JUST GO AWAY!" "Before you get yourselves hurt.." With that, Hiccup flew off as fast as he could, away from everyone...Ignoring the heart breaking cries of his father, Toothless, and his friends.

He flew as fast and far as he could, trying to hide from the world so the Fanged Fury wouldn't have him commit murder again...

You're not that boy they used to know Hiccup...Cause you belong to me...And me only...

Hiccup ignored the dark voice of the Fanged Fury that haunt his mind, never noticing several ships following him from the shadows.
