HTTYD Story of The Exiled.
Dragath the Exiled is considered much to be like a Hiccup - for those who don't know what a Hiccup is, they are the oddballs. Always screwing everything up even if he wasn't completely to blame. His life was horrible, no Viking would want to live like this. That is until it changed... the day of his Banishment he never felt more alive. Claiming what was rightfully his, he built an empire of Outcast warriors.
About 17 years after his rise to power, Dragath had made an empire like no other. At this time Berk had just discovered that Hiccup had managed to train a Nightfury, but instead of tossing him off the island, they made him a hero. He led the village through each raid using his skills to make Berk a better place. Then Hiccup realised that the dragons do not raid on their own... they have a queen located on Dragon's Island.
Using this, Hiccup leads the village into battle and defeats the queen with ease. Without losing a leg, Hiccup had the village of Berk build more houses, bigger docks, and stables for the dragons, as well as an Underground Tunnel system.
