His bond with Toothless, the last known Night Fury, changed the relationship between Vikings and dragons forever. Though sometimes uncertain of himself, he inspires others through creativity, courage, and empathy. Hiccup constantly searches for new dragon species, protects the Dragon Edge outpost, and works to keep dragons safe from hunters and those who would exploit them.

Snotlout Jorgenson A boastful, competitive Viking who constantly seeks recognition for his strength and heroic deeds. Snotlout rides Hookfang, a fiery Monstrous Nightmare that matches his bold personality. Though arrogant and often overconfident, he proves himself dependable when his friends truly need him. His rivalry with Hiccup and attempts to impress Astrid often lead to humorous situations, but beneath the swagger is a brave warrior with genuine loyalty. Over time, Snotlout matures into a capable fighter who values teamwork despite his oversized ego.

Astrid Hofferson A fearless Viking warrior and one of Berk's strongest dragon riders.

Though tough and competitive, Astrid deeply cares for her friends and will risk everything to protect them. Her determination, quick thinking, and unwavering trust in Hiccup make her an essential member of the Dragon Riders.

Ruffnut Thorston A mischievous, unpredictable Viking who thrives on chaos and confusion. Ruffnut rides Barf, one half of the two-headed Hideous Zippleback she shares with her twin brother, Tuffnut. Clever in unconventional ways, she often surprises others with unexpected insights hidden beneath her wild behavior. Ruffnut enjoys teasing her friends, exaggerating stories, and making situations more dramatic than necessary. Despite her antics, she is fearless, resourceful, and fiercely protective of both her dragon and the Dragon Riders.

Tuffnut Thorston An eccentric, fearless Viking with a bizarre sense of humor and an endless supply of strange ideas. Tuffnut rides Belch, the second head of the shared Hideous Zippleback with his twin sister, Ruffnut. He often embraces danger with reckless enthusiasm, creating confusion through absurd logic and outrageous plans. While he appears foolish, Tuffnut occasionally demonstrates surprising instincts and bravery when it matters most. His unpredictable personality and unwavering loyalty make him both a constant source of comic relief and a dependable member of the Dragon Riders.

Fishlegs Ingerman A gentle, intelligent dragon expert whose extensive knowledge makes him invaluable to the Dragon Riders.
