In StarCraft, which Protoss hero pilots the carrier Gantrithor?

In StarCraft, the Protoss hero who pilots the carrier Gantrithor is Tassadar.

Tassadar is a major Protoss character and the central hero of the original game’s Protoss storyline. He begins as a high-ranking executor tasked with fighting the Zerg, but his experiences lead him to question the rigid orders of the Protoss Conclave.

Gantrithor is Tassadar’s carrier and serves as his command vessel during the battle against the Zerg Overmind. Near the end of the original StarCraft campaign, Tassadar combines Protoss and Dark Templar energies in a decisive attack that destroys the Overmind.

Artanis later becomes a major Protoss leader, while Zeratul is the celebrated Dark Templar warrior who guides Tassadar. Fenix is another prominent Protoss hero, but he is not the pilot associated with Gantrithor.
