Here are some possibilities and why they might be mistaken for your search:
* "Batman" TV series (1966-1968): This series featured the iconic duo, Batman and Robin, but it ended in 1968. While they faced many villains, including some with supernatural elements, a "Queen of Vampires" episode never aired.
* "The Adventures of Batman" (1943): This serial was a much earlier iteration of Batman and Robin, but again, a vampire-themed episode isn't known.
* "The New Adventures of Batman" (1977-1979): This animated series featured Batwoman (in a separate episode from Batman and Robin). However, it aired in 1977, not 1972.
* Fan-fiction or a forgotten movie: It's possible your memory is pulling from a fan-made creation or a very obscure film.
To help you further:
* Do you remember any specific plot details or scenes?
* Are you sure about the year 1972?
