Hilliard

Hilliard was a four-legged lifeform resembling a large green dog. He was the bodyguard of the Curator of the Museum of Missing Ships. Despite his appearance, he was basically harmless.

Hilliard accompanied the Curator when he welcomed USS Enterprise (NCC-1701) officers James T. Kirk, Spock and Leonard McCoy to the Museum. When a group of Klingons seized the Museum and captured its inhabitants, he tried to attack them, but was shot by a sonic disruptor. He survived this and later freed the Starfleet officers from their bonds. Hilliard died along with the other inhabitants of the Museum when Limbo exploded.
