Summary
'Hiccup took her hand and yelped again as she pulled him out of the crowd and onto Berkian soil, just to the side of where the docks met the village. They continued on around the mingling Berkians and Berserkers, Rytin making a beeline for the forest.
“Come on, Hiccup!” she called back at him, grinning toothily. “It’s a beautiful day!”
As Rytin whooped gleefully, dragging him along, the fog and clouds seemed to lighten like Frigg herself was smiling. Hiccup couldn’t be sure what for, but he would soak in the sunlight while he could.
Berk rarely did anything but rain, after all.'
Or, Hiccup and Dagur become friends—brothers—the moment they meet.
This changes everything.

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?”

In which, six years later, the dragon raids are a thing of the past, but now a madman with a dragon army is threatening Berk. In which Astrid, now heir to the Chiefdom, convinces Stoick to ask the mysterious Dragon Master for help.
Hiccup obliges. It's his fight, after all.
However, he may have forgotten to anticipate how hard it would be to prepare for war alongside his old friends and family without letting them know it was him. But then again, what other choice does he have?
Toothless is finding the whole situation highly amusing.
Useless reptile.

Summary
From taking on multiple hunters on his own, including Viggo himself, to knocking out Snotlout, a very resilient viking, in a single punch, while also making him lose three whole teeth, to being the greatest blacksmith and inventor on Berk, there is very clear proof that Hiccup has got some STRENGTH behind his small frame. The Riders slowly realize that there's even more of it behind him than they had already known. An amount they're certain Thor himself would raise his fist to.
Or
Five times the Riders got a glimpse at Hiccup's hidden might, and one time they just had to ask about it.
