Sure, you think you know Wonder Woman. And we know you know Princess Diana. But, dear royals fans, did you know Wonder Woman is Princess Diana?

Yes, the Amazonian superhero is not only royal, but she shares a name and title with one of our all-time favorite royals. So let’s leave the fist fights to the fellas and focus on the match-up we’d really like to see: Princess Diana vs. Princess Diana.

1. They share royal roots.

Both Dianas share a namesake with the Roman goddess of the hunt – and childhood homes set in gorgeous locales. In her tropical homeland of Themyscira, Wonder Woman is known by her birth name, Princess Diana. When she travels beyond her Amazonian nation – which, incidentally, is populated and governed entirely by women with a distinct disdain for men – she is known by her alias, Diana Prince. (See what she did there?) Her mother is Hippolyta, the Amazonian queen from Greek mythology.

Princess Diana – whose childhood was rooted in bucolic Sandringham – acquired her title when she married Prince Charles. Her mother, Frances Shand Kydd, had royal roots that traced back to Ireland in the 16th century.

Title by marriage vs. title by birth? Advantage (slight): Princess Diana

2. They both rock tiaras.

In addition to her bracelets and golden lasso, Wonder Woman wears a tiara – which she occasionally hurls at bad guys as a sort of weaponized royal accessory. Princess Diana wore many tiaras throughout her reign but never threw one. (We’re certain she was tempted.) Still, Wonder Woman has but one tiara, while Diana had many – and hers were far sparklier. With real diamonds. Advantage: Princess Diana

3. They weathered complicated love lives.

Wonder Woman’s first true love is Steve Trevor, a U.S. Army intelligence officer whose plane crashed on Themyscira. (She nursed him back to health.) In Batman v Superman, Trevor is briefly glimpsed in an old photo (he’s played by Chris Pine) alongside Wonder Woman (Gal Gadot). She later hints that something terrible occurred after the WWI-era photo was taken, leading her to quit the superhero biz for 100 years. Other comic book iterations have seen Wonder Woman romance Aquaman, Batman and yes, Superman. (There’s a love triangle with seismic implications.)

Princess Diana’s own love triangle was grounded in the flaws of mortals but would become iconic in its own right. Advantage: Wonder Woman
