Linebeck first appears in Phantom Hourglass as one of the main characters who helps Link save the World of the Ocean King from Bellum. He provides transport for Link in his ship, the S. S. Linebeck, and is greedy and self-centered.

For the first half of the game, his goal is to obtain the Ghost Ship's treasure. After the Ghost Ship's treasure is revealed as merely a rumor devised by Bellum to attract people to the Ghost Ship, Oshus, revealed as the Ocean King, promises Linebeck one wish if he continues to sail Link across the oceans, to be granted after Bellum is defeated.

In the endgame, Linebeck saves Link and Tetra from Bellum by stabbing him, showing a rare burst of courage. Bellum, enraged, then possesses Linebeck.
