He’s Been Dead For Over Six Decades
In the DC Extended Universe continuity, Gal Gadot’s Diana first ventured out into man’s world with Steve Trevor in 1918, with the Amazon princess coming with the soldier to stop World War I. Diana and Steve became quite close during their short time together, but Steve met a tragic, yet heroic death when he flew the bomber carrying Doctor Isabel Maru’s deadly poison to a safe altitude and detonated it. Rather than be overcome by rage like Ares, the God of War, wanted Diana to be after Steve perished, the heroine instead called on her positive memories with Steve, which allowed her to see the good in humanity and ultimately defeat Ares.
