Battle Spirits: Fighter Force

Battle Spirits: Fighter Force is a Japanese animated television series based off the Battle Spirits card game, and a spin-off of the main anime series. The anime was produced by Studio Trigger and the first season aired on Nagoya Broadcasting Network between 2016 and 2017 in Japan. The anime has been licensed by NickFamily Studios and YTV Family, who are dubbing the series into English. YTV Family aired the series in Canada, while SurgeAnime TOO aired the series in the United States.

The series has had two sequels: Battle Spirits Fighter Force X and Battle Spirits Fighter Force Rumble. Following the end of Rumble, Nickelodeon Family announced the cancellation of Fighter Force in order to focus on the co-production of several Studio Aura anime.

In November 2022, Nickelodeon Family has mentioned that they are seeking to greenlight a reunion season which would feature the protagonists of each Fighter Force series (and serve as a conclusion to the spin-off series in general). If greenlit, the reunion season would be animated at BN Pictures (who also handled co-production for the rest of the spin-off series) and possibly Venga Tokyo, with some animation assistance from Studio YanYan.
