A villain I've always liked a lot, Vandal Savage, as one small part of his 50,000 year immortal history, in at least one story is very briefly shown to have been the one knifing women in the Jack The Ripper murders in 1880's London. Perhaps expanded on in another story I'm unaware of.

I first came across Vandal Savage in a Mike Baron and Jackson Guice story, in their brief FLASH run (2nd series, 1987), in issues 1-2, and 13-14. What I remember most about that run is Wally West was bagging more women than Hugh Hefner.

And another story I discovered after-the-fact, by Marv Wolfman and Gil Kane, in ACTION COMICS 551-554, that along wih Vandal Savage collects a lot of obscure heroes and villains in one story, and ends with a beautiful tribute to Joe Shuster and Jerry Siegel.

Wolfman and Kane also did great Superman stories in 539-541, and 544-546. Gil Kane provides a dynamic and strikingly different Superman.

Wolfman and Curt Swan earlier did a more whimsical Silver-Age-ish story with Vandal Savage in ACTION 515-516 in 1981. And a second one by the same team in 542-543 in 1983. )
