Wonder Woman's character was created during World War II; the character in the story was initially depicted fighting Axis military forces as well as an assortment of colorful supervillains, although over time her stories came to place greater emphasis on characters, deities, and monsters from Greek mythology. Many stories depicted Wonder Woman rescuing herself from bondage, which defeated the "damsels in distress" trope that was common in comics during the 1940s. In the decades since her debut, Wonder Woman has gained a cast of enemies bent on eliminating the Amazon, including classic villains such as Ares, Cheetah, Doctor Poison, Circe, Doctor Psycho, and Giganta, along with more recent adversaries such as Veronica Cale and the First Born. Wonder Woman has also regularly appeared in comic books featuring the superhero teams Justice Society (from 1941) and Justice League (from 1960).
During the Silver Age, under writer Robert Kanigher, Wonder Woman's origin was revamped, along with other characters'. The new origin story increased the character's Hellenic and mythological roots: receiving the blessing of each deity in her crib, Diana is destined to become as "beautiful as Aphrodite, wise as Athena, strong as Hercules, and swift as Hermes."
Steve Trevor died at the end of Wonder Woman after sacrificing himself to ensure that a plane full of deadly gas couldn’t harm anyone on the ground. Is this Steve Trevor the same Steve Trevor that we saw in Wonder Woman who was transported to 1984 because of something like time travel, a descendant of Steve Trevor’s who is also named Steve Trevor (and looks exactly like Pine), a clone, or something else entirely? (It’s a comic book movie, so anything is possible.)
