There could be an evil dragon that has been corrupted by dark magic. This dragon could be a threat not only to the other dragons but also to the Vikings. Hiccup and Valka would have to find a way to either cure the dragon or stop it from causing more harm. This evil dragon would be a powerful antagonist as it would have its own dark powers and a hatred for anything good, including Hiccup and Valka's efforts to create a harmonious world for dragons and Vikings.
Maybe a rival Viking tribe that has a different view on dragons. They see dragons as a threat rather than friends like Hiccup and Valka do. So they try to disrupt the peace that Hiccup and Valka are trying to build between the Vikings and the dragons. They could be constantly causing trouble, stealing dragon eggs or attacking dragons, which would force Hiccup and Valka to take action against them.
Perhaps in this fanfiction, Hiccup is out exploring on Toothless when they encounter a strange dragon behavior. Valka, who has been observing from afar, comes to their aid. She and Hiccup then work together to figure out what's wrong with the dragons. Along the way, they share stories about their individual experiences with different dragon species, and Hiccup is amazed by Valka's tales.
Mainly, it's Hiccup and Valka. Hiccup is the protagonist we know from the 'How to Train Your Dragon' series, always curious and eager to learn more about dragons. Valka, on the other hand, is a mysterious figure who has her own set of skills and knowledge regarding dragons. When they meet in the fanfiction, their different personalities and experiences collide, creating an interesting dynamic that drives the story forward.
Well, perhaps in the fanfiction, Hiccup is in trouble while on a dragon - riding adventure. Valka, who has been observing from afar, comes to his rescue. This leads to them spending time together, with Valka teaching Hiccup some new dragon - taming techniques she has learned during her time in isolation. They could also have heart - to - heart conversations about Hiccup's father and how Valka has missed so much of Hiccup's life.
The two main characters, Hiccup and Toothless, are what drive the story. Hiccup is the one who takes the first step in approaching Toothless, which is a big deal considering the fear and animosity between humans and dragons in their world. Toothless, with his powerful yet somewhat mysterious presence, is the object of Hiccup's curiosity. Their relationship is the heart of this fanfiction, whether it's about them learning to trust each other, protecting one another, or just having adventures together.
The main antagonist could be Littlefinger. He sees the early alliance between Jon and Daenerys as a threat to his own schemes. He might try to manipulate events to turn them against each other. He could spread false rumors about Jon's intentions towards Daenerys' claim to the Iron Throne or vice versa. His sly nature and ability to play the game of thrones from the shadows would make him a formidable foe to their budding relationship and their plans for Westeros.
Well, it might be about their first encounter. Maybe Hiccup is out exploring and stumbles upon Toothless in a hidden cove. He's initially scared but then realizes Toothless is different from the other dragons he's heard about.
A powerful dragon rider from a far - off land who has a grudge against the Berk tribe (Hiccup's tribe) could be the main antagonist. He or she sees Hiccup and Heather's marriage as a symbol of the growing strength of Berk and decides to target them specifically to weaken the tribe. They might try to steal their dragons or spread false rumors about their marriage to create unrest among the people.
It could be a dragon hunter who sees Hiccup in his dragon form and wants to capture him for study or to use his unique abilities for evil purposes.
A rogue dragon rider who has different ideas about how to treat dragons. He might see them as tools for power rather than friends like Hiccup does. This rider could be causing trouble for Hiccup and his tribe by stealing dragons or using them to attack other tribes.
A new dragon - hunter could be the main antagonist. He might be extremely skilled and ruthless, and Hiccup hides his strength to better understand this new threat and find a way to defeat him without putting his village in immediate danger.
