On October 16, 2018, it was reported that a Grimm spinoff was in development at NBC. The potential new series would feature a female Grimm as the lead character and could feature some of the original cast, either as regulars, or in recurring roles. The pilot was written by Melissa Glenn (Marvel's Iron Fist). Glenn will executive produce, along with Grimm EPs Sean Hayes and Todd Milliner. Original showrunners/co-creators David Greenwalt and Jim Kouf would return as consulting producers.
On May 12, 2019, NBC released their upcoming 2019-20 fall schedule, which did not include the Grimm spinoff. Elizabeth Tulloch later confirmed on her Twitter page that the show was not picked up.
