- Ascended Fanon: Maybe someday. On Faust's DeviantArt page for Ceres, she mentions that she'll consider suggestions for Ceres's symbol in the comments section below.
- Creator Backlash: In 2021, Lauren made a series a tweets showing off new designs for the girls, stating she no longer liked their original appearances and wanted to give them more diverse body types.
- Development Hell: Lauren Faust has pitched multiple animated series for Galaxy Girls over the years (one such pitch leading to Friendship is Magic), and back in 2007 she claimed to have been working on a short and shared some storyboard art. As of 2018, whatever progress has been made hasn't seen the light of day (probably because the following year Lauren got a certain job with Hasbro). Lauren has said that Galaxy Girls is currently "in stasis" until she can find the right partners. When asked about re-pitching the series on Twitter in December 2021, she said "not yet, but who knows?"
- God-Created Canon Foreigner: While they don't have toys, Lauren has drawn designs for a few other characters, namely Milky Way's little sister Andromeda and Pluto's bandmates Ceres and Eris.
- Keep Circulating the Tapes: New toys are not in production, so you'll need to buy them second-hand.
