The theme song was re-written to remove references to the Axis, reflecting the series' new present-day setting, and the action depicted in the opening's animated comic book panels was similarly updated. Beginning with the episode "The Man Who Made Volcanoes," the opening title sequence was changed again to an instrumental and more traditional "action scenes" opening. The animated stars used before and after commercial breaks were dropped.
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).

As a child, Steve Jr. had heard his late father's stories of adventures with Wonder Woman during World War II. It is essentially confirmed in the second season première that his father never introduced him to Wonder Woman and that he had never even seen her photographed. It is similarly implied that he and YN1 Diana Prince were unaware of each other. Diana is taken aback by the younger Steve's existence, implying that his father had never spoken of the boy to either Wonder Woman or YN1 Prince. This was particularly striking when she spoke to Steve Jr. about knowing his father well, from the j-shaped burn scar on his right shoulder, to the 20mm shell casing that he used as a paperweight.
