Some sources credit this as his introduction and others say he was in a comic strip? I've searched Google, but I haven't found any information on his first appearance. All I found was that, in the original story, Rogers fought the "Han" or the "Mongols." Any Rogers fans know just where he came from?
shareLong ago I read a book of old Buck Rogers comic strips.
Killer Kane was a rather comic, bumbling villain in them. In fact he started out as one of Buck Rogers's comrades but went bad.
From what I remember, his nickname didn't mean "murderer" but was short for "Lady Killer". A lady killer wasn't a female who murdered or a serial killer of women, but a playboy who "killed" women's reputations as virtuous ladies, I think.
And here is a link to an article about Killer Kane.
