Hiccup Haddock had so many reasons to become a villain. In this story, which i'd like to call a parallel universe, he ran away from Berk and became the most dangerous guy in the archipelago. He grew tired of not living up to his expectations, and when he shot down Toothless, he made a decision to leave Berk for good and run away with the dragons. (WARNING : This is just my idea for a story cuz I've been DYING to see a Villain Hiccup AU. Also sorry for grammar mistakes if any happen, english isn't my first language and I'm trying to improve it as much as I can)
