Gary and His Demons is an adult animated sitcom created by Mark Little and co-created by Mark Satterthwaite for Mondo Media's channel on VRV. The series follows a cantankerous, aging demon slayer who has nothing left to lose. Burdened by his Chosen One status and backed by a team of specialists he can't relate to, Gary struggles to keep interest in the Earth-saving duty he never asked for and doesn't want. In the series, Gary can not retire until his organization finds a suitable replacement for him. And they have failed to find such a replacement, despite Gary having twice had mandatory retirement parties.

The first season is directed by Mark Little and Louis Solis, and is primarily written by Little. The voice cast includes Little as Gary, Kayla Lorette as Leslie, Kyle Dooley as Hanley, Marito Lopez as Marito, and Miguel Rivas in various roles.

On April 13, 2022, it was announced there would be a second season and the series moved to Amazon Prime Video in Canada. Season 2 was released on October 6, 2022. In the United States, the second season was released on Freevee on July 7, 2023.
