Wallmaster

Wallmasters, also known as Clutches, are recurring enemies in the The Legend of Zelda series. Depicted as oversized, zombified hands, they have the ability to transport Link back to the entrance of a dungeon if he is grabbed by one. Also, there exists a similar enemy known as the Floormaster, which resides on the floors of dungeons, rather than the ceilings.

The Legend of Zelda
Wallmasters appear as giant blue hands that come out of walls. If one hits Link, it drags him back to the entrance of the dungeon, no matter how deep into it he is. As an additional annoyance, if Link picks up a clock, any Wallmasters in the room who has not yet left the wall are rendered unreachable until he leaves the room. Wallmasters are one of the most loathed monsters in the game by many fans; however, they have a fairly high rate of dropping Rupees.

The Legend of Zelda: A Link to the Past
Wallmasters are found in Skull Woods and certain areas of Ganon's Tower. While they can be killed, a room can never be cleared of them, as they seem to regenerate after a certain period of time, even if Link never leaves. They are, however, fairly easy to avoid. Their fall from the ceiling is preceded by a dropping sound, and their shadow can be seen on the ground before they land.

The Legend of Zelda: Ocarina of Time
Wallmasters take the form of zombified hands with clawed fingernails. They can drop from the ceiling and onto Link with little warning; the only sign of a Wallmaster attack being steadily growing shadow beneath Link and an ominous sound reminiscent of howling wind. While troublesome, Wallmasters drop more Rupees than most other monsters in Ocarina of Time.

Navi warns Link to "watch for the shadows of monsters that hang from the ceiling" when he enters a room with a Wallmaster in it. They can be found in the Forest Temple, the Bottom of the Well, the Shadow Temple, the Gerudo's Training Ground, the Spirit Temple, and Inside Ganon's Castle.

Interestingly, if the Link looks up in first-person while the Wallmaster begins to fall, it will disappear, probably because the shadow and sound are made before the Wallmaster is actually loaded on-screen.

The Legend of Zelda: Majora's Mask
Wallmasters are similar both in appearance and attack method to their Ocarina of Time counterpart. They can be found Beneath the Well and in the grave opened on the Final Day in Ikana Graveyard. When they drop from the ceiling, they drag Link to the beginning of the dungeon. Unlike Navi in Ocarina of Time, Tatl does not inform Link about the presence of Wallmasters when he enters a chamber where one dwells.

The Legend of Zelda: Oracle of Ages and Oracle of Seasons
Wallmasters are depicted as large, red hands. They fall from the ceiling in an attempt to take Link back to the beginning of the dungeon. They are seen more often in Oracle of Ages than in Oracle of Seasons.

The Legend of Zelda: The Minish Cap
Wallmasters are similar in appearance and attack method to Floormasters from The Legend of Zelda: The Wind Waker. Arrows are extremely effective against them.

The Legend of Zelda comics
In one storyline, Link is teaching Princess Zelda to fight in one of the dungeons, and soon realizes they are hopelessly outclassed. Telling Zelda that he needs to know she is safe because he loves her, he pushes her into the grasp of a Wallmaster, the result being that she is deposited back at the entrance to the dungeon. In a different storyline, a Wallmaster breaks Link's sword.

Freshly-Picked Tingle's Rosy Rupeeland
Wallmasters appear, but not as enemies. When Tingle encounters a statue of a hand with blue flames coming out of it, he can pour Hand Potion on it, causing a Wallmaster to appear and return Tingle to the beginning of the dungeon. This marks the first time that Wallmasters -- although they essentially do the same thing -- can be thought of as helpful rather than an enemy.

Super Smash Bros. Melee
Wallmasters do not physically appear, but they are mentioned in the description of the Like Like trophy. It states that Wallmasters are considered by fans to be the second most annoying enemy in the Legend of Zelda series, with Like Likes being number one.
