Like the previous two sequels, Subspecies 4: Bloodstorm (1998) begins with Radu's animated limbs grasping the Bloodstone and supplying his mouth with a few drops of Saint's blood. With some renewed strength, Radu manages to find refuge in his crypt. A car accident takes the lives of everyone but Michelle, who is discovered by a stranger named Ana. Upon seeing Michelle's reaction to the sunlight, Ana takes her body to her former professor, Dr. Nicolescu, who quickly determines that Michelle is a vampire. When Michelle wakes, Dr. Nicolescu promises to cure her of her vampirism. With his strength restored, Radu travels to Bucharest to claim the financial wealth one of his previous "fledglings", Ash, has acquired in the Vladislas name. Radu enlists Ash's help to track down Michelle, while Ash's own fledgling, Serena, attempts to play Radu and Ash against each other. Radu discovers Michelle's location, and Dr. Nicolescu agrees to give Radu what he wants in exchange for three drops of blood from the Bloodstone. Radu agrees, but it was only a trick to allow Dr. Nicolescu the opportunity to capture and stake Radu. Michelle arrives, releases Radu, and the two flee to safety. Serena arrives immediately after and gives Ana a key to the Vladislas crypt, where Radu is, with instructions to kill Radu. Ana and Dr. Nicolescu arrive at the tomb, but Radu awakens and kills Nicolescu. Radu turns his attention to Ana, but Michelle slices his throat, allowing Ana enough time to decapitate Radu. They burn his body and take the Bloodstone. Ash and Serena are waiting at the opening of the crypt, but a caretaker, hearing Ana's screams, opens the crypt and spills sunlight inside. Michelle is hidden in a coffin and transported out of the cemetery, while Radu's head sits on a pike burning in the sun.
