Well, obviously Hiccup would be one of the main characters. His character is central to the whole concept of refusing to kill dragons. Astrid could also be a main character. She might initially be on the side of the traditional view of killing dragons but gradually come to understand and support Hiccup's stance. Stoick, Hiccup's father, would be an important character as well. His position as the chief and his traditional beliefs would create a lot of conflict with Hiccup's new ideas. And of course, the dragons themselves, like Toothless, could be considered main characters in a sense. They are the ones that Hiccup is trying to protect and coexist with.
Perhaps a plotline where Hiccup's refusal causes him to be ostracized from the tribe for a while. During this time, he ventures out on his own and encounters a group of dragons that are also outcasts in their own way. Together, they form an unlikely alliance. As they work together, Hiccup learns more about the dragons' intelligence and emotions. This experience strengthens his resolve to change his tribe's perspective on dragons when he eventually returns. He may have to face challenges like convincing the tribe that the dragons are not a threat and that they can all benefit from a peaceful coexistence.
There could be some new characters introduced as well. Maybe a mysterious dragon rider from a far - off land who also has the ability to talk to dragons. This character could either be an ally or an antagonist to Hiccup, depending on their motives. Or perhaps an old dragon trainer who has long - forgotten secrets about the dragons' language that Hiccup has to discover.
Obviously, Hiccup and Toothless would be central characters. Astrid might also be there, as she is an important part of Hiccup's life. Other dragon characters like Stormfly, Hookfang and the rest of the dragon riders' dragons would likely be involved too.
The author could try to rewrite the fanfiction to better align with Hiccup's character. Make sure the dragons are depicted in a way that he would approve of.
Well, obviously Hiccup is one of the main characters. He is the one who has a special connection with the dragons.
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.
Obviously, Hiccup is the main character as the title implies she is the one becoming the dragons' queen.
The dragons that raise the twins are also key characters. They could be of different species, each with their own unique traits. For example, a Night Fury - like dragon could be very intelligent and stealthy, teaching the twins how to hunt and move quietly. And a Gronckle - type dragon might be more about brute strength, showing the twins how to stand their ground in a fight.
In this fanfiction, Hiccup is the central character as he takes on the task of taming the Red Death. Astrid could also be involved. She might be skeptical at first but later see the value in Hiccup's attempt. And the Red Death is the key character that the story focuses on taming. There could also be other Vikings in the background who either oppose Hiccup's idea or are in awe of his courage to take on such a dangerous dragon.
Obviously, Percy would be one of the main characters. He's the target. And then, the hunters as a group would be important characters too. There might also be some side characters like Percy's friends who could be trying to save him from the hunters.
