Perhaps a scientific experiment gone wrong could lead to time travel. The Vikings in the HTTYD world are known for their inventiveness. Maybe Fishlegs, being the more scientifically - minded Viking, creates a device that he thinks will enhance dragon communication but instead opens a rift in time. This would send the main characters, along with their dragons, back to a time when dragons and Vikings had a more hostile relationship, forcing them to use their modern knowledge to change the course of history for the better.
One idea could be Hiccup traveling back in time to the era when dragons first arrived in Berk. He could witness how the initial interactions between humans and dragons began and use his modern - day knowledge to try and improve relations even earlier. Another could be Toothless accidentally activating a time - travel device and taking Hiccup to a future where dragons are extinct, making them strive to find a way to prevent such a future.
Writing a good HTTYD time travel fanfiction requires several elements. One important thing is to have a unique concept for the time travel. It could be something like a time - rift caused by a powerful dragon magic. Then, focus on character development. Let's say Hiccup time - travels. He should grow and learn from his experiences in the different time. You can also introduce new characters from different eras. They can add more complexity to the story. Regarding the plot, create a series of events that are both exciting and logical. For instance, if the dragon riders travel to the future, they might find that Berk has become a desolate place. They then need to figure out what happened and how to fix it. This way, you can keep the readers engaged throughout the fanfiction.
The characters would face the challenge of not being recognized or being seen as a threat. If they time - travel to a time when their families or tribes didn't know them yet, they could be considered outsiders. For example, Hiccup might be seen as a strange boy with his un - Viking - like ways of handling dragons. Also, they would have to deal with the different cultural norms of the past. Things like how battles are fought, how the tribe is led, and how resources are shared could all be very different, and they would need to adapt quickly to avoid getting into trouble.
First, you need to have a clear concept of time travel in the HTTYD universe. Decide if it's a one - way trip or if there are rules for coming back. Then, think about how the characters will react to this new situation. For example, Hiccup might be both excited and a bit scared about exploring a different time period. You can also introduce new dragons that were extinct or not yet discovered in the original timeline. And don't forget to keep the essence of the HTTYD story, like the bond between humans and dragons.
One of the best things is seeing the characters' growth. In fanfiction, it might explore Hiccup's further development as a leader. For example, how he deals with new challenges in Berk. Also, the relationships between the characters can be delved deeper. Toothless and Hiccup's bond might be shown in more emotional and complex ways, like their adventures in new, uncharted lands.
It extends the story. After the movie ends, fanfiction can continue the adventures. Maybe Hiccup and his friends go on a new quest that was only hinted at in the movie. It gives fans a chance to keep exploring the world they love and see what could happen next.
A really interesting plot would be if a time - traveling villain from another dimension comes to the HTTYD world and tries to change the past to make dragons evil. Hiccup and his friends then have to travel through different time periods to stop this villain. Or perhaps the characters travel to a time when there were giant, prehistoric dragons that they have to deal with, and they learn new ways of dragon - riding from the ancient Vikings who tamed those behemoths.
In Kagome time travel past samurai fanfiction, the character development can be really engaging. Kagome has to adapt to a whole new way of life. She might learn samurai combat skills, which is exciting to read about. Also, the relationships she forms with the samurai characters can range from friendship to romance, adding depth to the story.
There's a lesser - known but very good one called 'Back to the Targaryen Roots'. The story follows a modern - day Targaryen descendant who somehow time - travels back to the height of their family's power in the past. It's interesting because it shows the contrast between modern values and the more medieval values of the Targaryen era. The character has to adapt quickly and the way they interact with historical figures is really engaging.
