- "O, the world of death is fantastic! I Must tell my family of this wonderful feeling! My lovely wife Mary will be next, then our little Henry and anybody else who drops by to visit! I must prepare all their gravestones! O, great and powerful Dracula! I pledge to be your servant forever!"
- —Message found in J. A. Oldrey's Diary
J. A. Oldrey is described by Mary as having been a good man before he was turned into a vampire by Gilles de Rais and Actrise. Once a vampire, Oldrey began to desire the blood of his wife and son. Cornell first encounters Master Oldrey inside the Villa where Oldrey is pounding on a door telling Mary to open it because he wants a drink. Mary refuses to open the door. At first, it appears to be a domestic issue until Oldrey transforms into his vampire form and attacks Cornell, since he is unable to get to Mary. Cornell defeats Oldrey who turns into a bat and vanishes into mist.
J. A. Oldrey is then found at the end of the stage in a crypt, feasting on his wife, Mary Oldrey. He confronts the vampire hunters one last time. Oldrey does not run away this time and is permanently eliminated. Unfortunately, he left Carrie and Reinhardt with another vampire they must take down. Nothing could be done for Mary, whom he had fed from.
