Koume and Kotake

Koume and Kotake are twin witches that are recurring characters in the Legend of Zelda series. They initially started off as antagonists, being surrogate parents to Ganondorf, but in the parallel world in The Legend of Zelda: Majora's Mask, they are friendly. Koume, the red, has power over fire, while Kotake, the blue, has power over ice.

In Super Smash Bros. 3DS/Wii U
Koume and Kotake appear as stage hazards on the Gerudo Valley stage in Super Smash Bros. for Nintendo 3DS, and use their respective powers of fire and ice. It is not certain how they affect the players.
