The Impostor Link (real name unconfirmed) is a character in The Legend of Zelda: Phantom Hourglass. He can be found in the northwest quadrant, sailing a ship that looks somewhat similar to the King of Red Lions. His outfit is almost exactly like Link's, except with a small white ball at the end of the cap. He is a middle-aged man, with red hair that connects to his beard.

In the fashion of Orca, the player participates in a minigame with him. If Link can hit him (without actually hurting him) 100 times, the impostor will give Link a Heart Container.

Trivia
According to Wikipedia, Imposter Link is a Gerudo.
