In this fanfiction, Hiccup might escape through a combination of his own skills and the help of his friends. Astrid, for example, could lead a rescue mission. Hiccup, while being held captive, might leave some subtle signs for his friends to follow. He could also try to build a small weapon or tool from the things around him. Once his friends arrive, they could create a distraction, allowing Hiccup to break free from his restraints and join them in the fight against Viggo.
Well, Hiccup is very resourceful. He could use the environment around him to his advantage. If he is locked in a place, he might find a weak spot in the structure, like a loose board or a hole in the wall. And he could call for Toothless secretly. Toothless, being highly intelligent, could find Hiccup and rescue him. Also, Hiccup could befriend some of Viggo's minions and convince them to help him escape.
In a fanfiction scenario, Viggo might kidnap Hiccup out of jealousy. Hiccup has a special bond with Toothless, a very rare and powerful dragon. Viggo, who has always been obsessed with dragons, may be envious of Hiccup's connection. He kidnaps Hiccup to try and take Toothless for himself. He might think that by having Hiccup in his control, he can make Toothless obey him. He could also use Hiccup as a bargaining chip to get more dragons from Berk.
Hiccup's friends would be extremely worried. Astrid, being Hiccup's closest friend and love interest, would probably be the first to take action. She would gather the other riders and start planning a rescue mission right away. Snotlout might initially be a bit hesitant, but the thought of losing Hiccup would push him to join in. Fishlegs would use his knowledge of dragons to figure out where Drago might be hiding Hiccup.
First, you need to have a clear idea of their characters and the setting. Then, think of an interesting plot that could involve both Hiccup and Viggo. Maybe start with a conflict or a mystery for them to solve together.
Perhaps the ending involves Hiccup actually being the key to saving Toothless from his own actions. Hiccup manages to communicate with Toothless on a deeper level, and they work together to defeat the real enemy that was causing Toothless to act out. In the end, their bond is stronger than ever, and they continue to protect Berk side by side.
Well, it varies a lot in fanfiction. Sometimes Hiccup and Viggo become unlikely friends, while in others, they remain bitter enemies. The plot depends on the author's imagination and creativity.
You might have the dragons play a crucial role. They could sense Hiccup's distress and lead the others to where he is. Or, there could be a secret weapon or magic that the heroes discover to defeat Viggo and free Hiccup.
He might be shocked at first. After all, finding a baby out of the blue is not an everyday occurrence.
A hiccup can change fanfiction in various ways. For example, it could be a unique character trait added to an existing character. If a character in a fanfiction suddenly has a hiccuping problem, it can add an element of humor or vulnerability. It might also be used as a plot device, like a hiccup being a sign of a magical spell gone wrong or a side - effect of some new power the character has acquired.
One possible plot could be that Toothless is under some sort of spell or mind control. Maybe a new villain in the How to Train Your Dragon universe has the power to manipulate dragons. Toothless, being a powerful Night Fury, is forced to kidnap Hiccup. Hiccup, of course, tries to figure out why Toothless is acting this way and how to break the spell.
His character could also develop in terms of his understanding of different kinds of magic. He starts off knowing only about the magic related to dragons. But in the fanfiction, as he watches and interacts with the Guardians, he begins to understand their magic. This could lead to him becoming more open - minded and adaptable. He might start to think about how the different magics could work together to protect both his world and the world of the Guardians. And this new knowledge could also change how he approaches problems back in Berk. For instance, he could try to incorporate some of the Guardians' ideas or magic - like things into his dragon - training methods.
