Constantin is a vampire. He appears in What We Do in the Shadows (TV series).
Constantin was an early guest at the 2019 Bi-Annual Vampire Orgy, appearing at the Staten Island vampire residence as the vampires were preparing while fully dressed in bondage gear. The orgy later came to an abrupt end when Jeremy, the supposed human virgin to feast on for the night, was unveiled to them while having sex with Constantin. After all the guests left, he was seen enjoying a card game with Jeremy and Colin Robinson.
