>>95407609It was actually revealed before the movie, waaaay back in season 1 or 2 of the original show.
I assumed though that they meant it's never been mentioned in the new series, which is a new continuity. They occasionally act like it's a sequel show, but they contradict the original show in too many little ways, especially with this new retcon.
In the movie, the Professor was shocked when the girls had superpowers, whereas in this show, he already had created one superhuman child.
