In a fanfiction scenario, perhaps Toothless kidnaps Hiccup because he believes it's the only way to protect him. There could be a great danger coming towards Berk, like an army of dragons that are being controlled by an evil force. Toothless thinks that by taking Hiccup away from Berk, he can keep him safe until they can find a way to defeat the threat.
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.
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.
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.
Well, it might be about their first encounter. Maybe Hiccup is out exploring and stumbles upon Toothless in a hidden cove. He's initially scared but then realizes Toothless is different from the other dragons he's heard about.
In the 'Toothless Eats Hiccup Fanfiction', it might be that there is an alternate universe where the relationship between Toothless and Hiccup is completely different. Maybe in this universe, dragons are more savage and Toothless hasn't formed the deep bond with Hiccup like in the original story. So, he sees Hiccup as just another source of food. This could explore how their relationship might have been if things had been different in this strange fan - created world.
The plot could involve young Hiccup's first encounter with Toothless. Maybe he stumbles upon Toothless in a hidden cove while exploring. Hiccup, being the curious and kind - hearted boy he is, tries to approach Toothless despite his initial fear. They gradually build a connection through shared moments like Hiccup offering food to Toothless.
One possible plot twist could be that Drago kidnaps Hiccup to use him as a bargaining chip against the dragons. Maybe he wants to force the dragons to submit to his will by threatening Hiccup's life. Another could be that Drago discovers some special power within Hiccup that he wants to harness for his own evil purposes. For example, Hiccup's ability to communicate with dragons might be something Drago wants to use to control all dragons.
Well, perhaps in this fanfiction, there's a new kind of magic discovered in their world. This magic messes with the natural order and causes Toothless to be able to impregnate female Hiccup. But then, they would have to face a lot of challenges. The village might not accept this strange occurrence, and they would have to figure out how to deal with the upcoming birth and the new life that is about to enter their world.
One possible plot could be that in a magical realm where the bond between Toothless and Hiccup is even more profound, an ancient spell or some kind of strange phenomenon causes Hiccup to be able to conceive. Toothless, being extremely protective, would then go to great lengths to keep Hiccup safe during the pregnancy. He might search for special herbs or a safe place for her to give birth. And along the way, they face challenges from those who don't understand this strange occurrence.
Another idea could be that a new and unknown force in their land has the ability to make the impossible happen, like male pregnancy. Hiccup becomes a target for this force for some reason, and Toothless has to protect him not only from the physical threats but also from the social stigma that might come with such an unusual situation. As they face these challenges, their bond deepens and they discover new aspects of their love for each other.
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.
