Arm Mimics are recurring enemies from the Legend of Zelda series. Resembling ghost-like creatures, they move parallel to Link. They have considerable defensive powers, as regular attacks from weak swords cannot harm them at all; when struck, they will merely recoil. However, they can be defeated with Spin Attacks or by using a stronger sword.
Arm Mimics are found within the Dream Shrine. They are also found in a cave located beneath the statue of The Mourning Mermaid. Initially, they are invisible, but after Link obtains the Magnifying Lens found in the same cave, it allows him to see them. They can be defeated while unseen, however.
Arm Mimics are found in various dungeons. They mirror Link's movements while he is near them, and can be defeated with a sword.
