Tuffnut Thorston

Although never said throughout the show, Tuffnut seems to be the dominant twin. Together, he and his sister love to get into trouble, even if it means getting scolded by the chief of the village. Tuffnut likes the idea of Ruffnut being in danger, as he states when Ruffnut was on fire one time, he just watched for a while before he decided to help put her out. Tuffnut enjoys the chance to argue and wrestle with his sister, although it usually ends with Ruffnut overpowering him, either verbally or physically. He shares many similar traits with his sister. The only thing that seems to be apparent in difference is he enjoys gross things as opposed to his sister as seen in Gift of the Night Fury, when he smiled as Toothless put Hiccup's drool-covered helmet on his head and she grimaced.

Despite having a close sibling relationship, Tuffnut is understandably frustrated when he has to share everything with his twin sister, but he's willing to make amends with Ruffnut to save their dragon. Although sharing a rivalry with his sister, on occasion, he will help her if she is in trouble. He often thinks highly of his own skills, claiming that he is the world's deadliest weapon. Ruffnut and Tuffnut seem to actively cultivate the impression of being completely crazy; competing between themselves to outdo each other's outlandish behavior. He always makes a joke in situations and loves being the center of attention. This, along with downplaying his intelligence and exaggerating his difficulty of paying attention, dramatically lowers everybody's expectations of him, allowing him to get away without being productive.

Tuffnut has sectoral heterochromia; most of his irises are a dark grey-blue, however, towards the top they are a yellowish-brown color. For unknown reasons, his eyes are a solid and brighter blue in all other appearances in the movie franchise.
