Ascended Fanon: In continuities where Wonder Woman does not explicitly have no father he traditionally remained unnamed and entirely unimportant given she was created specifically as a hero that shows what women can accomplish with the support of other women without the interference of men. Fans speculated for years that he had to be Hercules given that he's the only character Hippolyta consistently has a past with. In The Contest arc of Wonder Woman (1987) Diana asks her mother if she was conceived during Hippolyta and Hercules' fling before Herc betrayed the Amazons and her mother is upset, but doesn't refute the claim. Grant Morrison made this canon for the Diana of Wonder Woman: Earth One in 2016.
Complex legal issues resulted in Wonder Woman and her supporting cast being unable to appear in a number of DC television adaptations. For example, she was supposed to appear in "The Call", an episode of Batman Beyond, but had to be written out and replaced by Big Barda, and was also the only JLA member to not appear in Static Shock. The producers of Smallville have similarly said they tried to use her in the show, but were unable to due to legal reasons. Her sidekick, Wonder Girl, was also barred from appearing in the cartoon adaptations of Teen Titans and Young Justice (2010) (though for the latter, Greg Weismanhas said that the issues were eventually lifted). Wonder Girl finally joined the cast in season 2 of the latter series.
During her run on Volume 3, Gail Simone was denied permission to use Veronica Cale, a villainess created by Greg Rucka for Volume 2. Rucka later allowed Keith Giffen to use Veronica as a supporting character in his Doom Patrol run.
Gay Panic: While in Wonder Woman (1942) "Hypnota" and their sister only ever refer to Hypnota using male pronouns—though never come out and say Hypnota is transgender or non-binary—all subsequent appearances of the character call her "Hypnotic Woman" and remove all masculine traits from the character. While this might be excused as not wanting a villainous trans character such a reading is very forgiving, and forgets that Hypnota clearly already went by male pronouns before the betrayal and brain damage that led to their villainy.
Lying Creator: In the days leading up to the New 52's Wonder Woman (2011)Brian Azzarello promised not to change Diana's origin. In the book Diana's traditional origin, in which she has no father and her powers, strength and personality come from her mother and a society of women explicitly designed to show what they could be separate from the oppression of man is tossed out the window to make her the incestuous daughter of Zeus and his granddaughter Hippolyta, with all of her powers due to her father instead and the Amazons themselves certainly not responsible for any of her heroic traits as they're child murdering serial rapists and murderers.
Outlived Its Creator: Like so many Golden Age superheroes Diana's still going strong decades after her creator's death. Wonder Woman was created by William Moulton Marston (1893-1947). He contributed stories from 1941 to 1947. The series continued without him and the character remains popular.
Science Marches On: Originally, Paradise Island was kept hidden from the world by being always covered by clouds. When satellite mapping was invented, someone would have noticed that one spot of the ocean was always cloud covered and would have investigated. So it was changed to magic somehow keeping it hidden.
Several writers have said that they consider Wonder Woman to be bisexual, though it's never been explicitly stated in a story. In fact, her sexuality is usually treated as an Elephant in the Living Room, for she lived on an island with no men for most of her life. Made canon as of DC Rebirth.
Gail Simone wanted to make Hippolyta's attraction to women explicit in the text by marrying her and Phillipus during her run as writer on Vol 3, but as it never came to pass it remained only a bit of trivia.
Other Trivia
Diana's martial arts instructor in the late 60s-early 70s was initially called Ching, not I Ching. When he introduced himself in WW 179 (November '68) he said "Permit me to introduce self. I *CHING!*", that is, I am Ching. Diana addressed him as Ching in that and later issues, and the narration boxes also had his name as Ching. "I Ching" was probably a mistake by one of the writers. Perhaps they went with it because it sounded more inscrutable.
