When it comes to Superman and relationships, most people automatically think "Lois and Clark". From the very first issue of "Action Comics" way back in 1938, Lois Lane has been a love interest for Clark Kent/Superman. Lois even had her own comic book titled "Superman's Girl Friend, Lois Lane".
But Lois hasn't always been the only woman Superman or Clark Kent has been romantically involved with. The most obvious inclusions are Lana Lang and Lori Lemaris. While long-time fans will list others including Lyla Lerrol, Sally Selwyn, Lyrica Lloyd, Luma Lynai, Cat Grant, and Maxima (just to name a few).
Then there's Wonder Woman. With the 2012 announcement that Superman and Wonder Woman would become romantically involved from issue #12 of "Justice League" (on sale August 29, 2012), I thought I'd look back at previous pairings of this super couple throughout various comic book incarnations.
Superman and Wonder Woman announce their engaged to be married, and are seen kissing and declaring their love for one another in the story "Wonder Woman: Mrs. Superman" from "Superman's Girl Friend, Lois Lane #136" (February 1974). But it was all a ploy to save Lois from the Revenger.
Superman put a kiss on Wonder Woman in "Action Comics #600" (May 1988) in a story titled "Different Worlds", catching Wonder Woman off guard. Superman awkwardly admits to having thought about Diana constantly since first meeting her, even admitting to having had an "intense" dream about her. While Wonder Woman admits to also having feelings for Superman, the two agree to remain friends to give Wonder Woman more time to settle in to "man's world".
In the 2001-2002 "The Dark Knight Strikes Again" by Frank Miller, Superman and Wonder Woman have a daughter (called Lara).
Frank Miller also had the two characters share a passionate kiss in issue #5 of "All Star Batman & Robin the Boy Wonder" (July 2007). Superman wants to arrest Batman while Wonder Woman wants to kill him. It's implied the two have romantic feelings for one another, but the issue over what to do with Batman leads to a heated argument... which ends in a kiss.
The pairing of Superman and Wonder Woman was even the subject of a series of greeting cards for birthdays and valentine's day.
I also found a photo of an unlicensed pin (made in China) that was sold on Ebay showing the two embracing.
