The Power Glove is a type of handwear that increases the strength of Link. It has been seen in a total of three games from The Legend of Zelda series. With the added strength, Link can lift objects that he previously could not. It is similar to the Power Bracelet, as well as the Titan's Mitt.
A Link to the Past
In A Link to the Past, the Power Glove is found within the Desert Palace, serving as the main item of that dungeon. It is found within a Big Chest, meaning Link required the Big Key in order to obtain the Glove. The chest can be within the room in the far northwest corner of the first floor of the dungeon.
With the Power Glove on, Link can lift the white rocks that appear across Hyrule, opening up passageways, hidden entrances, and more. This includes the large and small variations. The Power Glove is required to complete the game, as Link cannot access the second floor of the Desert Palace without it.
Later on in the game, Link receives a more powerful version of the Power Glove, called the Titan's Mitt. This item, found within the fourth Dark World dungeon, Gargoyle's Domain, can be used to lift all different kinds of rock, including the dark green ones which were unliftable with the Power Glove. This mitt, along with the Power Glove, is required to complete the game.
Oracle of AgesOracle of Ages, the Power Glove is found in the Ancient Tomb. It is an upgrade to the Power Bracelet, allowing Link to lift larger and heavier items. Specifically, he can now lift the big blue statues that are common within this dungeon.
A Link Between Worlds
In A Link Between Worlds, the Power Glove is given to Link by Rosso in the Miner's House once he completes the Eastern Palace. They allow Link to lift small gray stones. The Titan's Mitt is an upgrade to the Power Gloves that will allow Link to lift the larger gray stones. They can be found in the Desert Palace.
