Tyrant is an Imperial-class Star Destroyer of the Imperial Navy. She is known for her reputation as the most battle-hardened Star Destroyer in the Imperial fleet, having been engaged in more battles and skirmishes than any other ship of the fleet. Once assigned to Darth Vader's Death Squadron, it has been commanded by the capable Captain Lennox, with Lieutenant Cabbel serving as executive officer. During the Battle of Hoth, Tyrant attempted to intercept the first Rebel transports to flee from Hoth, but was disabled by several shots from the Rebel's planetary ion cannon.
