Some facts about the character:
Appearance: A stocky and muscular Viking with dark brown hair and blue eyes. During the events of the second and third films, Snotlout appears with a small mustache.
Personality: Self-assured and smug, he often considers himself "the best of the best" among the riders and strives for praise and admiration at any and all occasions. Because of this, other riders consider him pushy, annoying, and possessing a colossal ego.
Dragon: A terrible monster named Hookfang, who is a complete copy of his master in character.

Character
They have similar personalities. They often quarrel, but mostly in jest; together with Bars and Vepr, they can defeat a minor enemy. They are very fond of their dragon, which is very similar in personality to their owners, and each twin is particularly fond of the head controlled by each rider.

Ruffnut and Tuffnut are rather inattentive and often make stupid mistakes, earning them, to put it mildly, a somewhat shady reputation within the tribe. They love danger and dirty jokes. They tease the rest of the dragon crew whenever possible. But most importantly, Ruffnut and Tuffnut had very strong skulls.
