Skull Kid

The Skull Kid is a character from The Legend of Zelda: Majora's Mask, but he also appears in The Legend of Zelda: Ocarina of Time. The Skull Kid is a mischievous being from the Lost Woods who uses an evil mask to seek revenge on old playmates because he believes they abandoned him. The mask's power, however, becomes too much, overwhelming and then controlling him. He is the primary source of conflict in the game. He was friends with the Four Giants until they left to the four temples, leaving him behind. This, at first, saddened him immensely, which in result infuriated him. He always had a thrill in pulling pranks on people, and he never understood the reason no one played with him, causing him to start thinking that they simply weren't good enough for him. Eventually, he befriended the fairy siblings Tatl and Tael on a rainy day. They made a close friendship and played together.
