Twelve Forever was a animated pilot short created by Julia Vickerman (Supervising Director for Clarence and Animator for Yo Gabba Gabba), which premiered in 2016 as one of many potential shows to be given a full series order by Cartoon Network. Twelve Forever was sadly cut, though Vickerman continued working on Cartoon Network as writer for the Powerpuff Girls Reboot. Twelve Forever would find a new home on Netflix, when the latter announced the series order in 2017.
Shadi Petosky, who is currently one of the writers for the Netflix series, has made tweets that the show has completed production and it's all up to Netflix as to its eventual release date.
The story of Twelve Forever is of Reggie and her friend Shane engaging in adventures within Reggie's created outer world, where she is seen as the superhero Twelve.
