Koloktos

Ancient Automaton: Koloktos is a boss in SS undefined. It is an enormous automation created to defend the Ancient Cistern from intruders.

Strategy
As Link enters the final room of the Ancient Cistern, he immediately encounters Ghirahim inside. Ghirahim supplies the dormant Koloktos with cursed energy, giving it the mobility and the power to battle Link.

Koloktos is held together by the red cores in its arms and torso. Aware of its weakness, Koloktos covers its torso with its bottom two hands. The uppermost arms carry sharpened blades that it occasionally throws at the young hero, which he can dodge or block with his Shield. When Link is near the automaton, it tries to crush him with its giant arms. By dodging this attack and using his Whip to grab the arms' joints, Link can break off the cores from its arms. After breaking off the first two arms, Koloktos will eventually use its lower hands to attack, giving the hero a chance to break them off as well and attack its chest core. Koloktos will reanimate and reattach its missing arms afterward and attack Link again.

After the boss has suffered enough damage, it pulls itself out of the floor and reveals its legs, giving it the ability to chase Link around the room. It also pulls out six cutlasses and cages its chest core to prevent Link from attacking it. The contraption will occasionally try to attack the hero with a barrage of slashes, which he can dodge by running away. This attack can destroy the stone pillars in the room, revealing Hearts inside. It can also summon three Cursed Bokoblins which will pursue Link. After dodging an attempted strike, Link can pull the cores out of its arms as he did with its first form. He can then pick up the boss' cutlass and use it to destroy its various parts, including its legs. Link must then slice its cage apart with the cutlass, exposing the core to attack. As before, Koloktos will eventually reanimate its broken parts and reattach them.

After defeating Koloktos, its cursed energy will combust. Link can then proceed to power up the Goddess Sword with Farore's Flame, turning it into the Goddess Longsword.

Trivia

 * In alignment with the Ancient Cistern's apparently theme, Koloktos's overall design seems to take inspiration from the deity.
 * At the beginning of the battle, Koloktos's facial expression is neutral. The more it is attacked, the more its face seems to twist into a mischievous smile. Furthermore, when Koloktos is defeated, it seems to laugh like a child before exploding.
 * Even though it has a cage to cover its weak spot, it only uses it once Link has damaged it considerably.
 * Koloktos can be damaged with Link's regular Sword even during the second phase of the fight, but it will not be defeated until its core is struck at least once with its own cutlass, even if its health is at zero.
 * If Link returns to the boss room, he will still be able to use Koloktos's cutlasses, but he will not be able to exit the room with them.

Nomenclature
Koloktos may be derived from "koło ktoś", a Polish phrase meaning "Round One". This can refer to its round torso and orb-like red cores.
