Linebeck

Captain Linebeck can arguably be considered one of the main characters of The Legend of Zelda: Phantom Hourglass despite the fact that he's not a playable character. During the whole game, he'll take Link across the sea via his steamboat in hope that he'll get a nice amount of treasure in the end. He agrees to go along after he learns that the treasure that he seeks is found on the ship that kidnapped Tetra.
