* RecycledScript: The short "Time Waits for No Girl" had its premise almost completely reused for the ''WesternAnimation/DCSuperheroGirls2019'' promotional short "[=#TheLateBatsby=]" that premiered with ''WesternAnimation/TeenTitansGoToTheMovies'', with the only significant differences being Wonder Woman replacing Wonder Girl, Jessica Cruz, Zatanna and Bumblebee being included among the heroines and the villain the girls confront being Mr. Freeze instead of Poison Ivy.
* RoleReprise: Creator/TaraStrong previously played Batgirl in ''[[WesternAnimation/BatmanTheAnimatedSeries The New Batman Adventures]]'', though she doesn't use the same voice in this series.
* WhatCouldHaveBeen: Lauren Faust really did try to turn this into a full show and has shared designs for [[https://twitter.com/Fyre_flye/status/631923460265000960/photo/1 Batman, Robin, Wonder Woman]] and [[https://twitter.com/Fyre_flye/status/631971119398940672 Harley Quinn]]. Apparently the [[https://twitter.com/Fyre_flye/status/631976909866270720 reason]] Cartoon Network turned this down was it just wasn't what they were looking for and they already had a show with girls in it. Though ironically enough, they would later pick up the full version of ''WesternAnimation/DCSuperheroGirls2019''. So... [[{{HilariousInHindsight}} yeah]].
* WordOfGod: Though never used in the series proper, Lauren Faust advises fans against mistaking Comicbook/{{Supergirl}}'s [[BigBeautifulWoman bulk for fat]] unless they want her to pummel them.
