Floormaster

Floormasters are enemies in some Legend of Zelda games

Ocarina of Time Floormasters
Floormasters are enemies in the game The Legend of Zelda: Ocarina of Time. They take the form of dead hands with clawlike fingernails.

Floormasters are rather difficult to defeat at first. When a Floormaster is attacked it will separate into three mini-Floormasters. They need to be destroyed before they unite. If a smaller monster manages to grab Link after two are destroyed, it turns into a new Floormaster. The spinning slash or Din's Fire is especially useful as mini-Floormasters tend to blindly run into Link after retreating. If a Floormaster turns green, it is invincible. Link will need to stay away from it until it goes back to its normal color, or defend himself with the Mirror Shield. Some Floormasters are invisible, so Link needs the Lens of Truth to see them, disabling the use of the spinning slash or Din's Fire.

They are related to the Wallmaster, a giant hand that dwells on the ceiling.

Majora's Mask
Floormasters appear in Majora's Maks too, especially in Ikana's castle. In this game the sunlight is their major weakness and they will be harmed upon contact. They can be also beaten by reflecting light via the Mirror Shield onto them.

The Wind Waker Floormasters
In The Legend of Zelda: The Wind Waker, they are black hands with a violet glow around them. They reside in small holes on the floors of the Earth and Wind Temples, one is also seen at the Forsaken Fortress later in the game. However, these holes are different - they move, wiggle, and perpetually suck inward as would a black hole. Their personality according to their figurine is surprisingly lonely.

A Floormaster's attack in this game is very similar to the Wallmaster's attack in The Ocarina of Time. They will try to grab Link and take him to a previous room, this will also happen to a partner. However, you will be able to see the Floormaster's hole before you are attacked. They can also pick up nearby objects and throw them at Link.
