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.
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.
His relationship with Astrid would become really strained. She'd be heartbroken that he doesn't remember their relationship, and she'd have to work hard to make him fall in love with her all over again. It would be a journey full of mixed emotions for her, from sadness to determination.
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 common theme is self - discovery. Since Ichigo has lost his memories, he has to figure out who he is again. Another theme is the importance of relationships. His friends play a crucial role in helping him regain his memories or adapt to his new state.
Friendship is a very common theme. Her friends usually come together to help her, like in many fanfics where they use their unique skills to try and jog her memory. For example, Rainbow Dash might show her some of their flying adventures together.
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.
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.
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.
