Nandor's Familiar is a character from the television series What We Do in the Shadows. In the show, familiars are human servants who assist vampires, often performing tasks like gathering information or running errands. Nandor, one of the main vampire characters, has a familiar named Colin Robinson, who is unique in that he is an energy vampire, feeding off the energy of others rather than performing traditional familiar duties. Colin's role as Nandor's Familiar adds a comedic element to the series, as he often engages in mundane conversations to drain energy from those around him. This dynamic highlights the quirky relationships between vampires and their familiars in the show's humorous take on supernatural life.
