Twinrova

The Twinrova appear as two 400 year-old witches named Katake and Komume. Katake is a master of fire, while Komume is a master of ice. They are the bosses of the spirit temple in The Legend of Zelda: Ocarina of Time. They are the surrogate mothers of Ganondorf.

After wandering onto their sacrificial alter, Link is forced to fight them with his mirror shield. Katake launches beams of fire, which have to be reflected at Komume, While Komume shoots beams of ice that must be reflected at Katake. After damaging them enough, they transform into a giant witch called Twinrova. (They call it Katake and Komume's double dynamite attack.) To defeat the Witch, Link must absorb three beams of fire or ice into his sheild, and reflect the attack.
