Beamos

Beamos are recurring enemies in the Legend of Zelda series. They are depicted as stone statues with rotating heads and a single glaring eye. Beamos attack anyone that comes within their field of vision with a ranged energy beam.

The Legend of Zelda: A Link to the Past
Beamos can be found in dungeons; however, they cannot be destroyed. They can only be avoided by hiding behind a rock or ledge.

The Legend of Zelda: Ocarina of Time and Majora's Mask
Beamos can be stunned with a Deku Nut, making their eyes shut for a few seconds. They can be killed by throwing a bomb at its head, causing it to explode followed by its body. It takes two bombs to kill larger Beamos.

The Legend of Zelda: The Wind Waker
Beamos react faster, and their beams can send Link flying. The most effective weapons are arrows; while timing can be difficult, they can also be destroyed with a bomb. However, the glowing ball only appears right before, and during the time it is firing its energy beam. There are two types of Beamos, red and blue, the blue being the weaker of the two. Amusingly, outside the Tower of the Gods, Kargarocs can be hit, or killed, by a Beamos's beam.

The Legend of Zelda: Twilight Princess
The appearance of Beamos in Twilight Princess is similar to those from The Wind Waker, resembling a column similar to typical Ancient Greek architecture for support and a bright, red eye which shoots laser beams. In this game, the eye present is inside a halved, rotating dome which rests upon the column, whereas in The Wind Waker, the eye spins levitated above it. Additionally, in Twilight Princess the eye is only seen in red, whereas in Wind Waker, Beamos's eye comes in shades of both red and blue. As in The Wind Waker, Beamos can be be defeated by shooting an arrow into its ruby crystal eye. They can also be moved in some dungeons to help solve puzzles.

The Legend of Zelda: Phantom Hourglass
Beamos in Phantom Hourglass are similar to those from A Link to the Past. Although their eye moves slower than in previous games, they have an almost 100% accuracy rate at hitting their targets. To avoid the beams, Link must either sneak behind the eye on them or temporally disable it with a bomb or arrow.
