Tsuze (ツース, ^?), also known as Fang and Tuss, is a minor character in Final Fantasy V. He is a werewolf that appears in the Crystal Room at Karnak. He was first thought to be a monster out to get the Crystal, but soon shows that he was there to stop the Crystal from shattering. Unfortunately, he fails. In the end, he sacrifices his life for the party to escape the crystal room and the impending destruction of Karnak Castle.

He hails from the village of Quelb of the Second World, as one of the werewolves there, noted as his eldest brother in the GBA version, laments the fate of Tsuze.
