In StarCraft, Tassadar commands the Protoss carrier Gantrithor.
Tassadar is a Protoss Executor who becomes one of the original game’s central heroes. The Gantrithor serves as his flagship during the struggle against the Zerg and in the campaign to defend Aiur.
The carrier is especially significant near the end of the Protoss storyline, when Tassadar joins forces with former enemies to confront the Overmind. His willingness to use both conventional Protoss forces and forbidden Dark Templar power becomes a decisive part of the campaign’s resolution.
Gantrithor is not the name of a general Protoss carrier unit; it is the proper name of Tassadar’s individual ship. The Aleksander belongs to the UED, while the Hyperion is associated with Jim Raynor in StarCraft II. This makes the ship name a lore detail rather than a standard unit label.
