The Wind Waker
Zuko appears in The Wind Waker as a member of Tetra's crew, and is also quite short. He has a red hat, very large sideburns, a blue and white horizontal striped shirt, green pants, and a skull buckle. He keeps watch, and uses his Telescope, which resembles Link's, to do so. He rarely speaks during the course of the game.
Zuko looks identical to one of the men in the painting in Hyrule Castle, which depicts the members of the royal family. It is heavily implied that the man in the painting is Zuko's ancestor, who once served a previous Princess Zelda.
During the beginning of the game, he can be seen with the rest of Tetra's crew, and he is looking through his telescope. He spots the Ghost Ship after the fog comes in, and informs Tetra of his discovery. During the end of the game, when Tetra's crew comes to rescue Tetra and Link, Zuko can be seen, along with the other pirates.
