With another Gal Gadot-led Wonder Woman coming in 2020, fans of the superheroine have a lot to look forward to in the next year as "Wonder Woman 1984" is set to premiere on June 5. While her Lasso of Truth and bright red and blue outfit have become well-known staples of the DC universe, there are also a lot of lesser-known facts about Diana Prince and the man who created her.

1. The man who created the character also invented the Lie Detector Test.

William Moulton Marston, commonly known as Charles Moulton, was not only the inventor of the polygraph test but also a Harvard graduate-turned-psychologist, reports Ranker. Additionally, he was reportedly a practicing polygamist and cited both his wife, Elizabeth Holloway, and the woman they both lived with, Olive Byrne, as inspiring Wonder Woman.

2. Her origin story is quite unique.

According to Tonsoffacts.com, Diana was originally formed out of clay, as stated in the first comics. In fact, it is said that the material she was created from was made out of the souls of women who had been abused or killed.

3. In 1942, she was banned for not wearing enough clothing.

At the time, Wonder Woman's book "Sensation Comics" was blacklisted by the National Organization for Decent Literature, which prompted the publisher to pen a letter to the bishop who ran the organization asking why the ban had occurred. His reply? "Wonder Woman is not sufficiently dressed," reports Cosmopolitan.

4. Her tiara has also doubled as a weapon.

It has been stated that her tiara is so sharp that it was even once used to cut Superman himself.

5. In most adaptations of the comics, Diana wore earrings. However, in Patty Jenkins' 2017 film, she does not.

In the 1970s live-action television version and in the Hanna-Barbera 1973 animated series "Super Friends," the superheroine sports earrings of some sort. Additionally, it has been noted that she wore white star earrings in Cartoon Network's 2001 television series "Justice League." However, the accessory was eventually dropped from the story as Wonder Woman's abilities were increased.

6. Marston found inspiration in other unusual places as well.

Marston, who believed having more women in charge would lead to a "more peaceful world," was inspired by the Suffragette Movement. This is why Wonder Woman would send many female villains to Reform (Transformation) Island as she believed they could one day be returned to society.
