In the 2010 film How to Train Your Dragon, Hiccup attends dragon training with the young Vikings.
The training sessions are organized by Gobber after Hiccup joins the group of Viking teenagers who are learning to fight captured dragons. The lessons take place in an arena and involve dangerous species such as the Gronckle, Deadly Nadder, and Monstrous Nightmare.
Hiccup’s private experiences with Toothless give him a different understanding of dragon behavior. Instead of attacking blindly, he studies what frightens or calms each dragon. This knowledge allows him to succeed in the arena, although his methods initially seem strange to the other students.
The subject is not a conventional school class such as shipbuilding. It is a practical combat-training program shaped by Berk’s long conflict with dragons, and Hiccup’s success eventually helps change the island’s traditions.
