Link's first appearance was in The Legend of Zelda, Link was designed with a green tunic and a green hat which (like Mario's design) was due to limitations in the NES hardware. This appearance has since been traditional for Link. One thing that has varied with Link is his age. In some games such as The Wind Waker and the first part of The Legend of Zelda: Ocarina of Time, Link is a young boy around the age of 12 whereas in The Legend of Zelda: Twilight Princess and the second part of Ocarina of Time, Link is depicted as a young adult around 17.
