Played by Chris Pine in the film, Steve Trevor is Wonder Woman's answer to Lois Lane. But while fans may be familiar with Trevor from the movie or the 1970s television show that saw him played by Lyle Waggoner, his romance with Diana has had more than a few ups and downs.
After his plane crashed in the ocean near Paradise Island, Trevor, an Air Force pilot, was rescued by Wonder Woman. It was love at first sight for both, and after Diana came to America, she set up a secret identity as Diana Prince, Trevor's assistant. Yet somehow Steve never seemed to figure out that his assistant and his superhero girlfriend were the same person. He only had eyes for Wonder Woman and that star-spangled bustier.
Though he called her "angel" for saving his life in the plane crash, Wonder Woman couldn't save him from every dumb decision he'd make, as Trevor was shockingly killed off in the February 1969 issue of Wonder Woman. And that's when things got really weird.
Wonder Woman and her mother Hippolyta beseeched Aphrodite to return Steve from the dead and she seemingly brought him back, only for Steve to be killed again by a demonic force. Hippolyta was so distraught at her daughter's despair that she later erased Wonder Woman's memories of Steve entirely.
But that turned out to be pointless, because a portal to an alternate universe opened up, and an alternate version of Steve came through, triggering the whole romance over again—until the second dead Steve came back from the grave! Eventually it was revealed that the "resurrected" version of Steve was actually the god of love Eros in disguise; he and Aphrodite then implanted the memories of the original, murdered Steve Trevor into the mind of the alternate universe Steve, merging them into one person. Diana and Steve then got married and lived happily ever after for about one week, at which point the entire universe was destroyed.
After the DC Universe was reformed, a new version of Steve Trevor appeared who was more a brother figure to Diana. He ended up marrying Diana's best buddy Etta Candy. But when that universe was also inevitably rebooted, yet another version of Steve debuted, this time as a bitter ex-boyfriend who acted as a liaison between the government and the Justice League.
All of which is weird enough, but then there's this crazy fact: in the hit TV series, there were two versions of Steve who were both Diana's boyfriend—and they were also father and son, played by the same actor. And you thought comic books were confusing!
