Gantrithor

The Gantrithor was a protoss carrier, commanded by Executor Tassadar. It is the most famous of several heavily armed "Super Carriers".

The Gantrithor was powerful enough that it single-handedly defeated an entire terran battlecruiser squadron under the command of General Edmund Duke.

History
The Gantrithor was the flagship of Tassadar's Expeditionary Force. It later appeared on Aiur, commanded by Tassadar.

Its final battle was the final protoss/terran combined assault against the Overmind. It was heavily damaged in the battle. The Gantrithor was destroyed when Tassadar used the energies of the Dark Templar and rammed into the Overmind, destroying the ship as well as the Overmind.
