Hiccup (voiced by Jay Baruchel) is the son of the great Storick (voiced by Gerard Butler), the leader of the tribe. He wants to slay dragons like his father - these dragons are the main natural enemies of the Vikings on the island - but every time he appears in the battle of slaying dragons, he only adds trouble to everyone. In a battle against dragons, Hiccup secretly injured the most mysterious "Night Fury Dragon" with a dragon shooter, and released, raised, and even tamed the dragon without the knowledge of the tribe, and named it "Toothless". Hiccup's mysterious behavior aroused the suspicion of Astrid (voiced by America Ferrera), a girl who was training dragon slaying skills together. Astrid discovered Hiccup's secret, but was also shocked by the wonderful experience of riding "Toothless" and flying in the wind. Gray decided to tell the truth to Stolic and his people who had returned from the expedition at the dragon slaying ceremony, and persuade them to give up slaying the dragon. However, he failed miserably and Toothless was captured. A greater disaster was imminent...
