Maybe it could be about Hiccup's journey to prove himself worthy of being the king. He might face challenges from other dragons or Vikings who don't believe in him at first. Then he uses his unique bond with Toothless and his understanding of dragons to overcome these difficulties and finally take the throne.
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.
Well, it could be that Hiccup is cursed by an evil sorcerer who wants to turn him into a dragon as a form of punishment. But as he turns into a dragon, he finds that he has a new connection with the dragon world. He starts to see things from a dragon's perspective and uses this to bring peace between humans and dragons in a whole new way.
The plot might start with Hiccup having a strange encounter, like stumbling upon a hidden cave with a magical artifact. This artifact could be the key to his transformation into a dragon god. As he becomes more dragon - like in his powers, he could gain the ability to communicate with dragons on a whole new level, understanding their deepest thoughts and feelings. And he would surely have to use these powers to protect Berk from threats that normal human - dragon alliances couldn't handle.
Well, perhaps the story could be about Hiccup getting magically transformed into a baby Night Fury. Then he has to learn how to survive as a dragon in a world that is both familiar and strange. He might have to rely on Toothless, his friend, to protect him and teach him the ways of being a Night Fury.
One possible plotline could be Hiccup's journey to earn the respect of the dragons and prove herself worthy of being their queen. Maybe she has to face challenges like rival dragon riders or ancient dragon prophecies.
Obviously, Hiccup is the main character as the title implies she is the one becoming the dragons' queen.
Well, it could be about Naruto discovering a hidden dragon realm. He might learn to communicate with dragons and gain new powers from them. Maybe he has to fight against an evil force that wants to control the dragons for its own dark purposes.
Well, one possibility is that Merlin uses his magic secretly to gain the support of the people. He might perform great feats during times of crisis, like saving the kingdom from a powerful enemy. And then, through a series of events, the nobles and commoners alike start to see him as a true leader and he is finally crowned king.
Well, the plot could involve Hiccup discovering his new role as the Prince of Dragons and having to deal with the responsibilities that come with it. He might have to unite different dragon tribes under his leadership and face challenges from dragon hunters who see his new position as a threat.
The plot could start with Naruto already having some ninja skills but being in a strange new world of pirates. He decides to form his own crew with people he meets who share his ideals. They embark on a journey across the Grand Line. Naruto faces challenges like dealing with the weather, which is different from what he's used to in the ninja world. There could be a big arc where he has to rescue a crew member from a powerful enemy's lair. And as he gets closer to the One Piece, more and more powerful foes try to stop him, but he perseveres until he becomes the Pirate King.
