Another character could be Astrid. In the fanfiction, she might play a role in Hiccup's journey to get stronger. She could be his training partner or offer advice based on her own skills and experiences. Also, there might be new characters introduced, like an old dragon trainer who has a lot of wisdom to share with Hiccup.
One plot development could be that Hiccup discovers an ancient technique for building stronger dragon saddles. This new saddle design not only gives him better control over Toothless but also allows him to perform more advanced maneuvers. As a result, he becomes a more formidable rider and his reputation as a dragon trainer grows.
There may be some extremely creative and boundary - pushing fanfiction out there with this premise, but it's not something that is typically found in the more well - known or widely - accepted "How to Train Your Dragon" fanfiction. Usually, fanfictions in this fandom focus on things like their adventures, friendship, and the development of their bond in a more traditional sense. So, while it's possible, it's not a common plot line.
One great 'Hiccup Gets Amnesia' fanfiction is 'Lost Memories' on FanFiction.net. It really delves into how the other characters react to Hiccup's amnesia. They struggle to bring back the old Hiccup while also dealing with the new, confused version of him. The story is full of emotion as Toothless tries his best to re - bond with Hiccup, which is really heart - warming.
I'm not sure if there is such a specific fanfiction. There are countless fanfictions out there, but this particular one might be quite rare or even non - existent. You could try searching on major fanfiction websites, but don't be too disappointed if you don't find it.
Astrid is likely to be one of the main characters to interact with Hiccup. She might be initially very confused or even a bit jealous depending on how she perceives Hiccup's new form. Stoick, Hiccup's father, would also have significant interactions. He would probably be shocked at first but then try to support his child in this strange situation. And of course, Toothless. Their bond is so strong that Toothless would surely be involved, perhaps trying to understand what has happened to his rider.
Astrid is an obvious choice. She already has a close relationship with Hiccup in the original story. Then there could be Ruffnut and Tuffnut's sister, who might see Hiccup in a new light and be attracted to his growing confidence. Also, some new characters from unexplored Viking tribes could be part of it. Maybe a healer from a far - off land who is intrigued by Hiccup's connection with dragons.
Well, perhaps in the fanfiction, when Hiccup is struck by lightning, it sends him into a coma. During this time, he has vivid dreams about the history of dragons and their connection to the lightning itself. When he wakes up, he has a new understanding of dragons that no one else has. He then uses this knowledge to help the village in a time of great need, like when a new and more dangerous type of dragon attacks. His experience with the lightning becomes a turning point in his relationship with dragons and his role in the village.
A common plot is the struggle of his friends to make Hiccup remember who he is. They might show him his old inventions or take him to places that hold special memories. Another plot is Hiccup having to relearn dragon training from scratch, which is interesting as he has to rediscover his own skills. And often, there's a plotline about his relationship with Astrid being put to the test since he doesn't remember their history.
One common scenario could be during a dragon fight. Maybe Hiccup's dragon Toothless accidentally knocks him off during a tricky maneuver, leaving Hiccup with a sprained ankle or some bruises. Another situation might be when exploring new, uncharted lands. He could step on a hidden trap and get a leg injury. Also, in some fanfictions, he might be hurt while trying to protect his village from a new threat, like getting hit by a stray weapon.
