Steve Trevor, Wonder Woman's ally and love interest.
Golden Age[]
In the original version of Wonder Woman's origin story, Steve Trevor was an intelligence officer in the United States Army Air Corps during World War II whose plane crashed on Paradise Island, the isolated homeland of the Amazons. He was nursed back to health by the Amazon princess Diana, who fell in love with him and accompanied him when he returned to the outside world. There she became Wonder Woman (and also his coworker, Diana Prince).
Modern Age[]
The 1985 comic book storyline "Crisis on Infinite Earths" retconned, or rebooted the fictional continuity of the DC Universe. At the end of the storyline, the Wonder Woman and retired four-star General Steve Trevor of pre-Crisis Earth-Two traveled to Mount Olympus to live with the Greek gods and goddesses, as many of the other pre-Crisis Earth-Two heroes died or merged into a new streamlined continuity. The Wonder Woman of pre-Crisis Earth-One was devolved back into the mystical clay from which she was formed (technically dying), thus allowing Wonder Woman and her supporting characters to be re-introduced with new origins, backgrounds and plotlines. With the restart of the series in the second volume after "Crisis on Infinite Earths", Steve Trevor was revamped to be considerably older than Diana. In addition, the two of them never had a romantic relationship. Years before Trevor's crash landing on Themyscira (the modern name for Paradise Island), his lost mother, Diana Rockwell Trevor, a pilot for the Women Airforce Service Pilots, had also crashed there, finding the Amazons battling a large monster. Seeing they were close to defeat, Diana Trevor used her pistol on the beast, giving the Amazons an advantage in the battle. Trevor dies as a result. After her death the Amazons considered the outworlder to be an honored hero for her sacrifice. It is from her that Queen Hippolyta named her daughter Diana and also from her that the Amazons came into possession of a gun originating from Man's World. It is this familial link that led the god Ares to manipulate Steve into bombing Themyscira to eliminate the Amazons. However while in flight and guided to the island, Trevor realized he was about to needlessly bomb civilians and attempted to abort the mission. Steve's co-pilot, a minion of the war-god, transforms into a monster in an attempt to continue the attack. Diana rescues Steve from the resulting disaster.
The New 52[]
In the aftermath of the 2011 "Flashpoint" storyline, DC Comics cancelled all of their monthly books and relaunched them with a rebooted continuity, in an initiative called The New 52. In this continuity, Steve Trevor is a long-time advocate for the Amazons, having lobbied the U.S. government for peace with the Amazons, arguing that they are benevolent. Steve then becomes Wonder Woman's U.N. liaison during her stay in Washington, D.C. and later becomes the head of the newly formed A.R.G.U.S., (Advanced Research Group for Uniting Super-Humans), as well as the UN's liaison to the newly formed Justice League. Promoted to the rank of Colonel, his assistant is Etta Candy and he has made his feelings and attraction to Wonder Woman clear to her, although his feelings were not reciprocated. The hero Black Orchid is revealed to be A.R.G.U.S. Agent Alba Garcia, working covertly for Justice League Dark to monitor John Constantine.
Media[]
The cartoons Super Friends and Batman The Brave and the Bold, do not tell how they met, and in the first he is an astronaut. The original plot was used in the old series Wonder Woman. An episode of the cartoon Justice League, alluded a little to the way they met in the plot of the golden age. In the animated film and in the film with actors who have the same name "Wonder Woman" they said that Steve when he landed on the island was thought to be part of an attack, but when in the interrogation (via rope of truth) it was revealed that he did not even dream that one day he would discover this island, he just fell by accident, and in both cases the appearance of the wonder woman was a mixture of her having to escort him back to America with her having to defeat the villain Ares. Appears in DC Super Hero Girls (web and cartoon).
