In How to Train Your Dragon, Snotlout Jorgenson rides a dragon named Hookfang.
Hookfang is a Monstrous Nightmare, a large dragon known for its powerful fire attacks and intimidating appearance. Snotlout is one of the young Vikings training to fight dragons, but the training program gradually becomes a way for the teenagers to understand and ride them instead.
Snotlout’s confidence and competitiveness often contrast with Hiccup’s analytical personality. Hookfang matches that attitude: the dragon is aggressive, strong, and difficult to control at first. Their partnership becomes part of the group’s transition from dragon hunters to dragon riders.
Hookfang is sometimes confused with Stormfly, Astrid’s Deadly Nadder, or Meatlug, Fishlegs’s Gronckle. The easiest distinction is the dragon class: Hookfang is a Monstrous Nightmare, while Stormfly and Meatlug belong to different classes.
