Nandor the Relentless (Kavyan Novak) is an ancient vampire and former ruler and warrior from his human life. He is one of the main characters of What We Do in the Shadows, a mockumentary vampire comedy series on FX.

Early on in the course of the series, we learn that Nandor, back in his human days, had thirty-seven wives. During season 4, while in search of a new wife, with the help of a djinn, he reanimates these paramours and we discover that many are men, which he casually explains was not unusual for the time. 

Later in the same series, we see Nandor also become enamored of the boyfriend of his familiar, Guillermo, a British man named Freddie. While often unaware and morally bankrupt, Nandor does occasionally have crises of conscience and tries to rectify his wrongs, to mixed results.
