The Infinite Hand is an enemy that appears within Ocarina of Time. These hands are usually found alongside Dead Hand and they will grab Link if he walks by. These arms will rise from underground and it is unclear what they are actually connected to. Link is able to defeat an Infinite Hand with his sword, but it proves to be rather difficult as the reach of the hand is longer than that of Link's range. Furthermore, upon being defeated, a new Infinite Hand will appear in its place a few moments after.
While it appears that an Infinite Hand is connected to that of a Dead Hand, in the Water Barrier corridor of Ganon's Castle, an Infinite Hand can be found without the presence of a Dead Hand.
