My favorite character from The Legend of Zelda: Majora's Mask is definitely the Skull Kid. Few personas throughout the franchise were as revolutionary as the child perverted by Majora's Mask. It's sad really because in Ocarina of Time the Skull Kid was an easy-go-lucky fellow and the power of the demon contained within this ancient artifact clouded all that was good in him and created an entity hell bent on destroying the world of Termina. In many ways the Skull Kid is the character I and many other youth of the modern world are able to connect with best due to societal pressures often influencing our minds and sometimes for the worse. It was the Skull Kid that led the rampage of NPCs which contributed to Majora's Mask having the deepest, darkest, and most developed story in franchise history.
