Nandor the Relentless, played by Kayvan Novak, is a character in the television series What We Do in the Shadows.
Nandor was once the bloodthirsty leader of the fictional kingdom of Al-Quolanudar in Southern Iran and a warrior serving the Ottoman Empire. As the oldest vampire, he is the self-proclaimed leader of the group, and as such frequently calls house meetings for frivolous discussions.
Although he genuinely cares for his human familiar Guillermo, he has difficulty expressing it. Nandor is also quite naive to the ways of modern society and humans, which often results in Guillermo becoming frustrated with him.
