Majora

""According to legend... the troubles caused by Majora's Mask were so great... the ancient ones, fearing such catastrophe, sealed the mask in shadow forever, preventing its misuse. But now, that tribe from the legend has vanished, so no one really knows the true nature of the mask's power... ...But I feel it.""

"A puppet that can no longer be used is mere garbage. This puppet's role is finally over..."

Majora is the primary antagonist of The Legend of Zelda: Majora's Mask. It inhabits a cursed mask that was used by an ancient tribe in it's rituals. It's intent is to destroy the town of Termina by bringing down The Moon on top of the city. For the majority of the game, the mask is worn by Skull Kid on the Clock Tower, drawing the Moon to Termina. Although the Skull Kid was unaware, Majora's Mask gradually began to take complete control of his mind, turning his harmless pranks on people to acts with malicious intents. Before the game's events, Skull Kid used the power of the mask to prank and curse others around him, such as Kafei.
