The name was restricted to his private persona in the original radio series, the two movie serials, and most of the television version (there were two slips in this last medium, one on the "Batman" appearance, the other in the last filmed episode of the "Hornet" series itself, "Invasion from Outer Space, Part 2"; this story is well out of sync with the rest of the run, and the writer, director, and even the line producer are people with no other credits on the program).
