Hiccup Horrendous Haddock
Hiccup is the son of Berk's chief, Stoick the Vast. His best friend is the night fury Toothless, with whom he experiences many adventures.
Toothless is the only known remaining Night Fury and Hiccup's best friend. Night Furies are known for their speed and are the only dragons that can spout blue fire. On his left tail fin he wears a prosthesis that Hiccup made for him.
Flame sword and helmet
Hiccup's helmet is made of a magical metal that he had personally made by Gobber. His sword is a magical relic from ancient times, which Hiccup has modified so that it now shoots flames with a push of a button.
