Kotake and Koume are witches that when combine their power create Twinrova in The Legend of Zelda series. Twinrova raised the Male Gerudo king, Ganondorf, to turn him into their puppet. Ganondorf becomes very strong then uses his new form of power to try and take over Hyrule in the Link game The Legend of Zelda: Ocarina of Time. Ganondorf, using his Ganon form, becomes stronger than Twinrova and is no longer under their control. Twinrova appears as the Spirit Temple's main boss in this game.
Twinrova has appeared in several Zelda games besides Ocarina of Time including The Legend of Zelda: Majora's Mask, The Legend of Zelda: Oracle of Ages and The Legend of Zelda: Oracle of Seasons.
