Masked Elder is a character from The Legend of Zelda: A Link Between Worlds. He is Sahasrahla's Lorulean counterpart and the leader of The Masked who worship the monsters that inhabit Lorule following the destruction of Lorule's Triforce.
Unlike his Hyrulean counterpart, the Masked Elder leads his followers in opposition to the Royal Family of Lorule, convincing them to worship and follow the monsters instead. This is implied to be the result of him and most of the inhabitants of Lorule having lost faith in the Royal Family due their role over the misguided destruction of their world's Triforce, which result in the ruination of the kingdom of Lorule.
As part of the A Link Between Worlds DLC, Skull Kid's Standard Outfit (Lorule) is a Masked Elder Recolor. It can be unlocked on a square located on the Hyrule portion of the Lorule Adventure Map.
