However, his life takes a dramatic turn when he befriends a dragon, which was considered an enemy by his tribe. This friendship not only changes his life but also the entire Viking community's perspective towards dragons. Hiccup evolves from being an awkward teenager to the greatest dragon master the world has ever seen, proving that strength comes in many forms and that compassion and understanding can be more powerful than brute force.
