How to handle the theme of Hiccup's mpreg in How to Train Your Dragon fanfiction?

You could start by imagining a unique backstory for Hiccup's reincarnation. Maybe he retains some memories from his past life or gains new powers.

You could have other characters care for him, like Astrid bringing him medicine and soup.

You could have him struggle with daily tasks and rely on his friends for help. It would add a layer of vulnerability and friendship development.

You could explore having a magical artifact or spell cause the mind control. Maybe it's a relic from an ancient civilization with unknown powers.

Well, one way could be to focus on Hiccup's inner struggle and determination to recover. Maybe show how this event changes his perspective on life and his relationship with dragons.

Well, you could describe Hiccup's symptoms in detail and how it affects his ability to ride and interact with dragons. Also, bring in the village healer to add some drama and tension.

One way is to develop a unique sign language for him and the other characters to understand. This could add an interesting layer to the story and showcase the bonds of friendship and understanding among them. Also, you could explore how his muteness affects his relationships and self-perception.

One way could be to have him go on a solo adventure to prove his worth and find a way back.

Well, it varies. Some fanfics might use the injury as a plot device to drive character development, while others might explore how it changes the dynamics within the group.

It depends on the context and the tone of your fanfiction. You could describe it as a tender moment of care or as a comical event.
