Who could be the main antagonist in a 'hiccup gets struck by lightning' fanfiction?

Well, perhaps in the fanfiction, when Hiccup is struck by lightning, it sends him into a coma. During this time, he has vivid dreams about the history of dragons and their connection to the lightning itself. When he wakes up, he has a new understanding of dragons that no one else has. He then uses this knowledge to help the village in a time of great need, like when a new and more dangerous type of dragon attacks. His experience with the lightning becomes a turning point in his relationship with dragons and his role in the village.

Rachel Berry could be a great main character. Given her ambitious nature, being struck by lightning could add an extra layer of drama to her journey of achieving stardom through the glee club.

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.

Maybe an ancient being that was sealed away long ago but has now been awakened due to Naruto's newfound power. This being has a natural hatred for those who can control lightning and sees Naruto as a threat to its plans of taking over the ninja world. It has the ability to manipulate shadows and uses them to counter Naruto's lightning attacks.

It could be a rogue ninja who was once rejected from the lightning sage training and now wants to destroy the entire concept of the lightning sage. He might have developed his own dark lightning - based techniques to oppose the traditional ones.

It could be a rogue ninja from a hidden village who has also mastered lightning jutsu and wants to prove himself stronger than Naruto. This ninja might have a personal vendetta against Naruto or Konoha.

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.

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.
