The world of comic book superheroes is such a massive interconnected web of characters that it's easy to lose track of who is related to whom. So in anticipation of Wonder Woman coming out on June 2, you may be wondering is Wonder Woman related to Superman? With names so similar, there is bound to be a familial connection, right? Well, don't let their titles fool you since these characters with grand adjectives in their names aren't related and come from two very different worlds.
Gal Gadot's version of Wonder Woman was first introduced in Batman v Superman: Dawn of Justice and in that film, it's made clear that Superman and Wonder Woman aren't from the same place. (Superman says that Lex Luthor's monster at the end of the film is from his world and she responds, "I've killed things from other worlds before.") The Wonder Woman movie will show the world that Diana Prince is from and, unlike Superman, her home is actually on planet Earth — albeit in a mythical place.
While it has been well established in film over the years that Superman is from the alien planet Krypton, the origin story at the core of Wonder Woman will show that Diana Prince is really an Amazon princess from the island of Themyscira. Themyscira is an isolated island on Earth that is the home to Princess Diana and her fellow Amazon immortals who are based off of Greek mythology. Her parents in Wonder Woman are Hippolyta and Zeus (yes, as in the Zeus) and her god-like origins help explain her superhuman powers and why she hasn't aged at all between the events of the prequel Wonder Woman and Batman v Superman: Dawn of Justice.
Considering that Princess Diana and Kal-El (Superman's birth name) have supernatural origins and traditionally dress in red, blue, and gold, thinking they could be related is understandable. Yet, you may be confusing Wonder Woman with the other female warrior of the DC universe — Supergirl. Supergirl is related to Superman and is traditionally depicted as his cousin, but Wonder Woman is not related to this "super" family.
Yet, that doesn't mean that the DC comics haven't played with bringing Superman and Wonder Woman together in another way — by having them romantically involved. For example, in Frank Miller's Batman: The Dark Knight Strikes Again, Superman and Wonder Woman have a daughter named Lara and in the graphic novel Kingdom Come, Clark Kent married Diana after Lois Lane died and the two had a son together named Johnathan Kent.
While there's no evidence that the DC movies will make Superman and Wonder Woman romantically involved in the future (plus, Superman isn't quite available right now after the events of Dawn of Justice), it's good to know that the two superheroes aren't related in case the films ever move in that direction. And though they do not come from the same place, their upbringings make them aliens to Earth, so Wonder Woman and Superman will always have plenty to bond about — relatives or not.
