A "Grimm" comeback may turn from fantasy into reality.

NBC is developing a spinoff of the supernatural drama, which ended last year after six seasons.

The spinoff would be written by Melissa Glenn ("Marvel’s Iron Fist"), with original co-creators David Greenwalt and Jim Kouf serving as consulting producers.

The show would reportedly center on a female Grimm, the latest in a line of guardians who are sworn to keep the balance between humanity and mythological creatures called Wesen.

It would introduce new characters, but also bring back some returning fan favorites, as they face new dangers and mysteries. No actors are attached as of yet.

The original series starred David Giuntoli as a Portland detective who discovers he is a Grimm. Giuntoli is now on the ABC drama "A Million Little Things." Other cast members — including Russell Hornsby, Silas Weir Mitchell, Sasha Roiz, Reggie Lee, and Elizabeth Tulloch — have all booked projects since the series finale.

"Grimm" was a solid ratings performer for NBC on Friday nights. The show is also owned by NBC, which is in the spinoff's favor.
