He was voiced by David Tennant.
Spitelout is a tall, muscular Viking with a stubble that eventually grows into a beard. He also wears a helmet decorated with yak horns and a gray tunic.
Spitelout takes great pride in his son Snotlout, but he often pressures the latter to become a great Viking and to always be a winner. Spitelout is also a rather stubborn Viking who sometimes likes to do things on his own, though it is revealed that his actions are ways to prove his worth to Stoick. He seems to be rather relaxed in the face of familiar danger, which is proven when he did not flinch when the Singetails tried to attack him in order to free the captured Deathlout.
