Blind the Thief is a character and dungeon boss featured in A Link to the Past.
Before Blind is met in person, his origins are revealed by a man in Kakariko Village tells Link that his house was once Blind's hideout, and that he was a leader of a Gang of Thieves. Hyrule Historia states Blind, and his gang were among those who sought the triforce, and were transformed into demons by the Dark World's curse.
Blind the Thief resides in Gargoyle's Domain, also known as Thieves' Town, a dungeon found within the Village of Outcasts. Blind is originally disguised as a Maiden which Link rescues from a cell within the dungeon. Upon being rescued, he follows Link around for the remainder of the dungeon. Blind, disguised as a Maiden, asks Link to take him outside. If Link tries to take Blind out the main entrance to the dungeon, Link is stopped and told not to go this way. Blind strongly resembles Stalblind from The Legend of Zelda: A Link Between Worlds, both in name and appearance.
Link needs to blow up a hole in the ground on the top floor, causing light to shine down into the boss room. When Link takes Blind into the boss room and exposes him to light, his true form comes out and the boss battle begins.
Blind hovers around either the top of the screen or the bottom of the screen, alternating, and shoots laser beams at Link. His head is the weak point and can be damaged with the Sword. After a few sword hits, his head splits from his body and floats around the room shooting beams at Link. A new head grows from Blind's body and the battle continues as normal, except with the original head flying around the room shooting beams. After taking more damage, the second head splits like the first one, and a third head appears on Blind's body. After a few more sword strikes, Blind will be defeated.
