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.
A fanfiction could center around Hiccup and Toothless time - traveling. They end up in a different era where dragons are feared even more than in their own time. They have to find a way to get back home while also trying to change the perception of dragons in this new time period. This would involve a lot of challenges as they would be in an unfamiliar world with different rules and beliefs.
One characteristic is the exploration of their deep bond. It often delves into how they communicate without words, like their special connection that goes beyond the normal human - dragon relationship. Another is the adventure aspect. Writers may create new quests or challenges for them to face together.
One great 'hiccup x toothless fanfiction' is 'The Bond Beyond Words'. It beautifully explores the deep connection between Hiccup and Toothless in a new adventure. The author does an amazing job of capturing their unique relationship.
There might be some out there. Fanfiction communities are full of creative and sometimes out - of - the - box ideas. However, this particular 'hiccup pregnant by toothless' concept is not something that is likely to be mainstream. It could be a very rare find, or perhaps it exists in some more experimental or less - known fanfiction circles. You may have to dig deep into different fanfiction archives and websites to see if it exists.
Another theme is adventure. Since they are often in the world of dragons, many fanfictions use their adventures to strengthen their bond. They face dangerous situations together and in the process, their love for each other deepens. It could be fighting a new and powerful dragon or exploring an unknown land. This adventure aspect adds excitement to the relationship.
Love and romance can also be a prevalent theme. Writers might imagine a romantic relationship between Female Toothless and Hiccup, exploring how their different species might overcome obstacles in the name of love. It could involve how they communicate their feelings, given their unique natures. There are also themes related to self - discovery. Both characters might learn more about themselves and their places in the world through their interactions with each other in these fanfictions.
I'm not really into this specific concept, but in general, fanfiction often explores unique relationships. In this case, it might involve a very different take on the characters' bond, perhaps with Toothless in a more human - like form. However, it's a very niche and often not a canon - compliant idea.
There are some out there. You can try searching on fanfiction platforms like Archive of Our Own. However, keep in mind that mpreg (male pregnancy) is a very specific and often fictional concept within fanfiction, and the quality can vary greatly.
