#Usagi usually had a male twin if the author was straight and didn't want to break up Usagi/Mamoru

I'm fully aware that the reason that there are two ChibiMoons on many of the musical posters is that there are two actresses playing her. Child labor laws require the switches. However, it amuses me that the posters appear to show identical twin ChibiMoons. So many original moon babies back in the day were either Usagi's twins, ChibiUsa's twins, or ChibiUsa's twin daughters. Hell, I have twin daughters and triplet grandchildren for ChibiUsa!

I've always loved the worldbuilding involved with giving any of the moon sailors a magical sibling, specifically a twin. ChibiUsa especially would have a vastly different life and outlook depending on if her twin was (or wasn't) also age-stunted (in the manga), magically-inert at first, whatever.

It's just a fun thought exercise.
