Stalker

The Stalker was an Imperial Star Destroyer that was originally the fastest ship in Vader's Death Squadron. It was originally assigned to the Outer Rim of the Galaxy to find new worlds to subjugate, but it was selected to form part of Death Squadron by Darth Vader himself. As one of the Star Destroyers to take part in the attack on the Rebel Base on Hoth, the Stalker pursued Rebel Transports far out into space in an attempt to take down as many Rebels as possible, and it racked up several kills in this endeavour.

The Stalker later participated in the Battle of Endor, and it was saved from destruction by the wise surrender of the ship's captain following the destruction of the Second Death Star over Endor. However, he never followed up on his surrender terms and later rejoined with the rest of the surviving fleet. However, the Stalker's captain disagreed with the self-appointed fleet admiral and took his ship away in disgust.
