One interesting plot point could be how Hiccup adjusts to the new physical form. For example, he might struggle with the different clothing styles and social expectations for girls in his world. Another could be the reactions of his friends. Some might be shocked at first, while others could be more accepting and help him through the transition. There could also be a plot point about how this change affects his relationship with Toothless. Maybe Toothless initially doesn't recognize him and Hiccup has to find new ways to bond with his dragon.
Well, a great plot point might be Hiccup's exploration of the female perspective. As a girl, he could start to notice things he never did before, like the way girls are treated in the village or how they interact with each other. Also, there could be a part where he uses his new form to his advantage. Say, he's able to infiltrate a group that only allows girls, and he discovers some important information that helps his community. And then, of course, there's the whole idea of how he gets turned back. Is it a magical spell that he has to reverse? Or does he learn to accept his new form and that becomes the new normal?
A possible plot point is that Hiccup, now as a girl, faces discrimination or different treatment from some of the more traditional members of the village. This could lead to a story arc about him fighting for equality. Another aspect could be in the realm of romance. Maybe a character who was previously just a friend starts to see Hiccup in a new light romantically. And there could be a plot involving his skills as a dragon trainer. Since he's in a different body, he might have to adapt his training techniques. For example, if physical strength was part of his old training methods, he now has to rely more on other skills like agility and finesse.
One interesting plot point could be the discovery of the pregnancy. Hiccup might initially think Toothless is ill, but then realizes what's actually happening. Another could be the search for a way to reverse it if he's not ready for such a situation. Maybe he travels to a far - off land in search of a wise old dragon or a powerful witch.
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.
In this fanfiction, a plot point could be how Anakin's power manifests in his child form. Since he was already extremely powerful as an adult, as a child, it could be both a wonder and a danger. His raw power might be harder to control, and it could attract unwanted attention. Additionally, the story could focus on how Anakin's experiences as a child this time around impact his view of the Force. He might develop a new and unique understanding that could set him on a different path compared to his original one.
The way Ash adapts to Pikachu's instincts could be really interesting. He might find himself being more drawn to shiny objects or having an urge to store food in a certain way. And his relationship with his own Pikachu (if it still exists in the story) would be very different. They could become like equal partners instead of trainer - Pokémon.
Well, one interesting plot point could be how Harry adapts to his new snake form. Maybe he discovers new abilities like slithering really fast or having a heightened sense of smell. Another could be how his friends react. Do they recognize him right away or is it a struggle? And then there's the whole aspect of how he communicates in his snake form. Does he hiss in a way that can be understood by other magical creatures?
Often, the bond between Hiccup and the Dragon Queen is a central plot point. For example, in many fanfictions, they start off as strangers and gradually learn to trust each other.
One plot development could be the reaction of the Avengers or other superheroes to Peter's transformation. They might be initially confused or even skeptical about whether it's really Peter. And Peter, as a girl, would have to prove herself all over again in the superhero community. There could also be a plot where she discovers new powers or abilities that come with her new form. This could lead to her being more of an enigma in the superhero world and having to figure out how to control these new powers while still maintaining her identity as Peter Parker at heart.
One plot development could be that Hiccup discovers an ancient technique for building stronger dragon saddles. This new saddle design not only gives him better control over Toothless but also allows him to perform more advanced maneuvers. As a result, he becomes a more formidable rider and his reputation as a dragon trainer grows.
One interesting plot point could be how Hiccup adjusts to his new dragon form. He might have to learn to fly and use his new abilities, like breathing fire or having enhanced strength. Another could be his interactions with other dragons. Since he was once a human, he might have a different perspective compared to regular dragons, which could lead to unique relationships.
One possible plot could be that Ash wakes up one day as a girl and has to deal with all the changes in his daily Pokémon adventures. For example, he might have to adapt to new clothing styles and different social interactions. His Pokémon might also react in various ways to his new form.
