Sarah Kerrigan commands a Zerg Leviathan in StarCraft II: Heart of the Swarm.
A Leviathan is a gigantic organic Zerg creature that functions as a living capital ship. In Heart of the Swarm, Kerrigan uses one as her mobile base while rebuilding the Swarm and pursuing the forces responsible for the attack that changed her life. The Leviathan provides transportation, biological functions, and access to Kerrigan’s campaign operations.
The ship’s organic design reflects the Zerg approach to technology: instead of constructing machines, they grow living organisms that serve military and logistical purposes. This contrasts with the Terran Hyperion, a mechanical battlecruiser used by Jim Raynor.
Gantrithor is a Protoss carrier associated with Tassadar, while Norad II is a Terran battlecruiser from the original StarCraft storyline. These names belong to other factions and eras, making them common but incorrect alternatives.
