I know what some of you are thinking. You’re thinking, “What the hell am I talking about?” Well this Stiletto character is from Superman mythology kind of and I have proof. In mythology Lois really didn’t have the name stiletto but she had the name Superwoman. The name "Superwoman" was originally copyrighted by Detective Comics in an effort to prevent competitors from using it. The appearance of the name "Superwoman" in a DC comic was a story in Action Comics where Lois Lane dreams that she has gained superpowers from a blood transfusion from Superman and launches a career as Superwoman.
That isn’t it folks. The story of Superwoman gets more interesting for Lois Lane but I still don’t like the idea of her being a super heroine. This would be revisited in a 1947 Superman comic in whom a pair of magicians cast a spell on Lois, making her believe she has superpowers. Superman is forced to play along with the ruse for a time, using super-speed to invisibly intervene in Lane's adventures, supporting the illusion. She briefly sports a costume modeled on Superman's before the spell is broken. A story has Lois actually gaining superpowers thanks to one of Lex Luthor's inventions, and launches a short-lived career as Superwoman. I hate this just as much as ya’ll do but the facts, sadly, have to be the facts. At least Smallville didn't go as far as Lois and Clark: The New Adventures of Superman. A version of Superwoman appeared on the show in the season three episode, "Ultra Woman." Clark lost his powers when a red kryptonite laser beam hit him and transferred his powers to Lois. Both of them were unaware of the transfer, until Lois pulled down an iron gate with her bare hands. Mrs. Kent made her a costume and Clark introduces her to Metropolis as Ultrawoman.
