Dr. Kreitzer is a psychologist who worked as the head doctor of the Catwell Rest Home and Spa. He disguised himself as the ghost of Dr. Nathaniel Catwell, the rest home's founder, in order to keep his patients at the rest home.
Physical appearance[]
Dr. Kreitzer is a balding Caucasian male with yellowish skin and white hair on the sides of his head. He wears a doctor's outfit consisting of a brown collared shirt, a black necktie, and a white coat with notch lapels.
Personality[]
Dr. Kreitzer posed as a misguided but well-meaning psychiatrist. Dealing with many mentally-unstable patients in his career, he, like his colleague, dismissed his patients' claims of ghost sightings as hallucinations. However, he was later revealed to be a greedy man concerned with profiting from the rest home. Seeing the rest home as a business, he exploits vulnerable rich people, institutionalizing perfectly-healthy and sane people in order to maximize his profits. As such, while he poses as a dutiful man of service, he is really a deceptive businessman.
History[]
Scooby-Doo (DC Comics)[]
As the head doctor of the Catwell Rest Home and Spa, Dr. Kreitzer participated in a scheme to convince his patients they were mentally ill so they would stay at the rest home. Kreitzer disguised himself as the ghost of Dr. Nathaniel Catwell, the rest home's late founder, and terrorize the patients, so their experience would be dismissed as a hallucination. He also institutionalized the members of Mystery Inc. when they claimed to know a "talking dog," which he and his colleague, Dr. Faraday, described as a mass hallucination.
Dr. Kreitzer unmasked.
While he and Faraday performed a psychiatric evaluation on the members of Mystery Inc., Kreitzer continued to terrorize them as the ghost. However, while attempting to terrorize another patient, Mrs. Voorhees, he fell into a trap prepared by Mystery Inc. and was captured. He was subsequently unmasked, exposed for his crimes, and handed over to authorities. Faraday, uninvolved with the crime, assumed authority over the rest home in Kreitzer's place and discharged all its patients after Mystery Inc. proved they were sane.
