Twinrova

Kotake and Koume, collectively known as Twinrova, are a pair of Gerudo witches who have appeared in four Zelda games, most notably in Ocarina of Time, in which they act as the Boss of the Spirit Temple. They are also known as the Sorceress of Ice and the Sorceress of Flame, respectively. The two sisters are able to fight individually with elemental attacks or combine together into a more powerful form known as Twinrova. They are both the surrogate mothers of the Gerudo King, Ganondorf, and thus are among his more devoted servants.

Their speciality is brainwashing others to serve Ganondorf (most notably Nabooru ) and merging to form the stronger witch "Twinrova," where their combined power is much deadlier. The brooms the sisters use to fly become scepters with which Twinrova performs her spells.

Ocarina of Time


Kotake, Sorceress of Ice, and Koume, Sorceress of Flame, are the surrogate mothers of Ganondorf. They both have green, wrinkled skin and dress in black robes with white Gerudo patterns near the hems and an obi-like belt around their waists. Kotake's association with ice is noted by a blue jewel on her forehead, blue slippers and the markings on her headband are in red with a blue border, whereas these distinctions are red on Koume to highlight her association with fire.

Koume tends to be leader of the two, usually appearing first and deciding what their course of action should be. She is the first to introduce herself during the boss battle, and is also the one who comes up with the idea to combine with Kotake to form Twinrova.

Strategy
Once Nabooru is defeated as an Iron Knuckle in the Spirit Temple, Link proceeds into the next room. The boss room has four small platforms surrounding a larger central platform. Link must climb the central platform in order to trigger the cutscene. Koume and Kotake emerge from the smaller platforms and tell Link that they will "burn him to the bone" and "freeze him to the soul", before circling above him as the Sorceress Sisters: Twinrova and flying off in different directions.



Koume and Kotake fight using magic bolts of the elements from which their power comes: fire and ice. Using the Mirror Shield, Link is able to redirect the attacks of one sister against the other. After taking a total of four hits, the pair will use their "Double Dynamite Attack" and merge into Twinrova, a single being with the combined powers of both witches.

Once merged into Twinrova, the Mirror Shield remains essential in winning the battle. Link is able to use it to absorb the power of both the fire and ice spells. He is required to collect three consecutive charges of one type of spell, which then allows him to release the spell back at Twinrova. However, since Twinrova frequently alternates between fire and ice attacks, care must be taken to only block attacks of one type at a time; blocking a fire attack followed by an ice attack, or vice versa, will cause all power currently stored in the Mirror Shield to dissipate.

Once Twinrova is injured by the reflected attack, she collapses on one of the four outlying platforms, allowing Link the opportunity attack with his sword. After a sufficient number of strikes Twinrova will be defeated, at which point she will split back into Koume and Kotake. The two witches then say they are going to get "get serious," but realize shortly thereafter that they have halos above their heads. The witches' distress over their defeat fades when their conversations turns into an argument about their age, after which they ascend to the afterlife in a column of bright light.

Kotake
In Majora's Mask, Kotake is the owner of the Magic Hags' Potion Shop, where she sells the standard selection of Red Potion, Green Potion, and Blue Potion. However, she doesn't sell Blue Potions immediately - she requires a Magic Mushroom in order to make them, which she will happily take from Link if offered to her; and she will then use it to create a free Blue Potion for Link, and the Blue Potion will be available for purchase for the remainder of the three days.

Kotake cares for her sister very much. When Kotake hears that Koume was attacked by Skull Kid in the Woods of Mystery, she gives Link a bottle of Red Potion to deliver to Koume. If a whole day passes and Link does nothing to help, Kotake will leave her shop and proceed to the Woods of Mystery herself to search for Koume.

Koume
Koume is the guide for Swamp Boat Tour. She occasionally goes into the Woods of Mystery to look for mushrooms for Kotake to use in the Magic Hags' Potion Shop. However, one day she ran into the Skull Kid and was injured. Link is sent by her sister to find her in the nearby woods. Upon discovering her, she asks for Red Potion to heal her. If Link tries to give her a potion in any form other than his human one, she calls him a "weirdo" and tries to avoid his attention by playing dead. Once Link gives her the potion, she returns to her post at the Swamp Boat Tour, where she gives Link one free tour in return for healing her.

Oracle of Ages and Oracle of Seasons
In Oracle of Ages and Oracle of Seasons, Koume and Kotake send Veran and Onox to cause chaos and light two of the three flames needed to resurrect Ganon; the Flame of Sorrow and the Flame of Destruction. Once the flames are lit, the two kidnap Zelda to light the final flame, the Flame of Despair, by sacrificing her. Link fights the sisters both individually and as Twinrova, as in Ocarina of Time. After Link defeats Twinrova, she chooses to become the vessel for the ritual herself instead of Zelda, so that Ganon can return. Unfortunately for the pair, their sacrifice is in vain as it only allows a mindless, raging Ganon to come forth. Thus, Link is able to defeat it and save the day.

Strategy
Link's battle with the sisters begins similarly to their battle in Ocarina of Time, with the sisters casting magical projectiles at Link that he must deflect back at them. However, Link must use his sword to deflect them rather than his shield. The Mirror Shield, an upgrade that can only be attained in a Linked Game, can protect him from their magic, as it can in Ocarina of Time, but it does not reflect it. After the sisters have taken three hits (it doesn't matter who has taken how many, so long as the total is three), they fuse together and become Twinrova.

Twinrova alternates between two phases of attack, which affect the room around her and Link. In her cold phase, the room's floor is covered with slippery ice and Twinrova materializes spiked ice crystals that she launches at Link and which ricochet off the walls. In her hot phase, parts of the floor become lava pits and Twinrova launches fireballs. Link must strike Twinrova with his sword several times to stun her, and once she is stunned, he must use a Mystery Seed on her to actually damage her.

Super Smash Bros. for Nintendo 3DS
Kotake and Koume make a cameo appearance in the Gerudo Valley stage in Super Smash Bros. for Nintendo 3DS. They appear as a stage hazard, probably creating the fire that destroy the bridge in the middle of the stage.

Trivia

 * It can be assumed that in Majora's Mask, Kotake supplies Clock Town with potions due to the fact that if Link gives Koume a red potion purchased at the Trading post she still states that it smells like one of Kotake's.
 * The writing on Kotake's and Koume's headbands are katakana which simply reads their names.
 * Koume and Kotake are named after the old twin sisters in Japanese mystery novel.
 * "Koume" is a Japanese pickled plum and "Kotake" is a type of bamboo in Japanese.
 * "Twinrova" may a portmanteau of the English word, "Twin", and the Japanese word.
 * The center of the symbols out of which Koume and Kotake rise in the boss room display the Fire Medallion and Water Medallion (theorized by many to originally be the Ice Medallion), respectively.
 * Kotake and Koume are called "" and Twinrova is called "" in the German version of Ocarina of Time.
 * The scene where the Twinrova sisters brainwash Nabooru again is included in the introductory cutscenes of the Ocarina of Time (seen when the player leaves the Start button idle for several seconds).
 * Mago, a fire conjuring witch enemy in The Adventure of Link, bears a similarity to the Twinrova, particularly Koume due to her relation to fire.
