Protossima

Protossima is a massive Protoss Warship, designated as the Protoss Mothership for all intents and purposes. The ship is rarely seen, only ever being deployed to cleanse planets of Zerg infestation, and when it is deployed it never directly engages the Zerg forces, always hanging back and deploying troop carriers, dropships and gunships to sweep the surfaces of Zerg-infested planets.

Crewed by thousands of Protoss including the revered and feared Protoss Zealots, the Mothership strikes fear into most space travellers when it is seen - as the Protoss often make little distinction between their Zerg foes and other races in the Galaxy. The Protoss will accept help in destroying Zerg planets when they feel it is necessary, but they will usually call upon their allies to carry out surgical strikes on Zerg targets - few non-Protoss ships have ever had the honour of being contacted and invited to aid in the destruction of a Zerg World.
