FLCL Alternative

FLCL Alternative is an original video animation series created by Kazuya Tsurumaki, directed by Katsuyuki Motohiro and co-produced by Adult Swim and Production I.G. It is a sequel to the original FLCL, as well as FLCL Progressive.

On March 24, 2016, Adult Swim announced that it is co-producing, with Production I.G., 12 new episodes of the series FLCL that will air on Toonami. Back for the new seasons are series creator Kazuya Tsurumaki, serving as supervisor with director Katsuyuki Motohiro (Psycho-Pass) and character designer Yoshiyuki Sadamoto (Neon Genesis Evangelion). Also joining this season is writer Hideto Iwai (Last Dinner).

On March 20, 2018, a teaser for the two new seasons was released and it was revealed that FLCL Progressive will premiere on Adult Swim's Toonami block in June of 2018, followed by Alternative in September. Adult Swim initially planned to simulcast the English subtitled version of each episode at adultswim.com as they aired. However, the release of the subbed versions of Progressive and Alternative were pushed back to November to align with the Japanese release. In Japan, FLCL Alternative will air as a feature film, opening in theaters on September 7, 2018.

At 12:00 AM on April 1, 2018, the first English subbed episode of the series unexpectedly premiered on Toonami as a special April Fools surprise. This episode marked the first time a full-length Toonami series or movie aired with English subtitles. The English dubbed episodes began airing on Adult Swim's Toonami block on September 8, 2018 at 11:30 PM. The series is rated TV-14-DLSV on Adult Swim.
