Tall man (Dream-Eaters)
From Tardis Wiki, the free Doctor Who reference
This Tall Man, along with the rest of London, was sent to sleep by the Bodach. He later became part of the Bodach's sleeping army which assaulted Gryffen Manor. The Bodach were soon defeated by K9, causing the Tall Man, along with the rest of the army, to be freed from its control. (K9TV: Dream-Eaters)
