Summary
Son of Stoick, Heir to Berk, talking fishbone, the first ever Viking who can't kill a dragon but never known as Hiccup Haddock.
Hiccup had enough of everyone and once he came across a particular dragon, he can't help but fill his mind with ideas. Ideas such as,
Running away.
He leaves and strives for a living outside in the Archipelago, but years after his success in befriending dragons, he's forced into a nostalgic predicament; forced to see familiar faces he wishes to erase from his mind. Especially the one and only girl he has yet to move on from.
What will Hiccup do? With his past catching up to him once more, with an upcoming danger from the dragon hunters?
"Maybe something stupid."
Or,
Hiccup runs away before fighting Hookfang without anyone noticing and leaves for the outer archipelago. He rises to an anonymous saviour of dragons and is soon forced to see the people of Berk that he left behind. They face an upcoming danger and maybe the Berkians will finally come to understand Hiccup and his dragon antics.

Summary
“Just got that feeling. The one where you’re pretty sure you’ll crawl out of your own skin if you stay in place for one second longer.”
Dagur snorted. “You’re talking to the king of being unable to stay put. Trust me, I know what you’re talking about.”
The silence that followed felt like prompting. Hiccup sighed, drawing his knees close to his chest.
“Do you ever feel like there should be… more?”
“More of what?”
“Just,” Hiccup vaguely gestured, “more. This can’t be all there is, right?”
(A scene rewrite of HTTYD 2 where Heather, Dagur, and Hiccup are siblings, featuring one son of Eret)

Summary
__𓆩ꨄ︎𓆪__
"Not all monsters are born. Many are made."
__𓆩ꨄ︎𓆪____𓆩ꨄ︎𓆪__
Bitten by an unknown dragon and forever changed, Hiccup learns fate can be crueler than he ever imagined. Now he finds himself haunted by uncontrollable powers and desperate for an impossible cure.
After a near-fatal mistake, Hiccup vanishes. Fleeing Berk with Toothless, as the bite awakens something dark and untamed within him. Presumed dead, he disappears into the mists, knowing he can never return without endangering not only himself, but his dragon... and his people.__𓆩ꨄ︎𓆪__
Over the next six years, whispers spread: of a monstrous, nameless rider who frees captured dragons and burns hunter camps to ash, leaving only the blackened earth and obsidian scales of a dragon no one seems to recognize, or so they say. Some have taken to calling him a child of the Gods. Others, a curse sent from Hel to plague the living—riding into every battle with an army of undead dragons at his back. They call him Ragnarok.Series

Gods, Mortals, and Those Left Behind by Sarnai4 for Nilva123, Abyss_Ower

13 Jun 2025
Tags
Summary
Ancient Greece is a brutal place, only becoming more dangerous as monsters attack city after city. It is up to heroes to stop them. Maybe even the aspiring hero, Heracles (Snotlout), can prove he has what it takes, but what about his cousin, Daedalus (Hiccup)? Goddesses and gods like Athena (Astrid) and Zeus (Stoick) often dismiss him when he enters their temples. Disliked by the mortals and immortals, Daedalus seemingly has no way to survive when he too is targeted by the monsters. A hero can only be made on a battlefield after all, never near a forge…at least all but one fierce god feels this way.

Summary
His back was throbbing and he was 100% sure he had a migraine. He grumbled in annoyance and rest his head on the ground. He was laying on his side as he felt the pressure on his right arm, which curiously didn’t hurt anymore. In an effort to control his limbs, he tried to move his legs which ended up to be successful, yet they felt…off. A little heavier. He thought none of it, he was probably tired after that whole fiasco. Whatever venom that dragon had injected in him, must not have been the killing type. He shook his head and reached his hand up to fix his hair.
Until he saw a jetblack paw in place of his hand.

Danny's Bizzare Adventure: Those After by DeerlyQueery
Fandoms: Danny Phantom, How to Train Your Dragon (Animated Movies), DreamWorks Dragons (Cartoon)
28 Apr 2025
Tags
Summary
A collection of short stories about Danny's time after the events of the movies have concluded. Each chapter will have its specific potential triggers marked beforehand. Some will be sad, some will be happy, some will be chaos, as the Riders get to find out what Danny's world is like and old enemies appear to discover the new. Each chapter is loosely-connected but for the most part, should stand on its own unless otherwise stated. Unknown number of chapters, this could theoretically go on forever if I think of things.
Tags to be updated as chapters are added.

Summary
The Riders never considered they'd one day rescue a prisoner of Viggo, just around their age. Baffled at how little they knew of the Barbaric Archipelago, how home wasn't in their recollection. But in reality, the former captive had a secret to keep. And it certainly wasn't an easy thing to be pried from his lips.

Summary
This is my first fanfic on A03, it's about the Netflix series RTTE (Race to the Edge), in the Universe of HTTYD (How to Train your Dragon). It is a Viggo Grimborn x Fem!Reader.
An old friend of the riders pays a visit to the Edge, reigniting an old passion of adventure that burns through the complacency that watered down her fire. She grasps her new life and doesn't let go, finally feeling the freedom of fight and flight. Her curiosity grows as she gets the chance to live life on the wild side, even more so when one late night she happens upon the chance of a lifetime. However, in heeding her friends encouragement to enjoy herself, she finds herself in an unexpected and unique situation. Finding herself in more adventure than she bargained for, she embraces it, dancing with the life-threatening dangers most find terrifying, toying with the balance of her life daring it to send her into the deep end.
