Roiland, who voiced two of the animated TV show characters and created the video game High on Life, pleaded not guilty to the charges.
Justin Roiland, who co-created the animated series Rick and Morty and provided the voice of two of the title characters, is awaiting trial on domestic violence charges against his ex-girlfriend.
The criminal complaint obtained from prosecutors in Orange County, California charges Roiland, 42, with bodily harm and sham imprisonment by threats, fraud, violence or fraud against the woman, who was living with him at the time.
The woman was not identified in court documents.
Roiland pleaded not guilty.
The incident occurred in January 2020 and Roiland was charged in May of that year, but the charges apparently went unnoticed by the media until NBC News reported on them Thursday, when a pre-trial hearing was held on the case.
Emails seeking comment from attorneys for Roiland and representatives for Cartoon Network, which airs Rick and Morty, were not returned immediately. Roiland will return to court in April. A trial date has not been set.
Roiland and Dan Harmon created an animated science fiction sitcom about a mad scientist and his grandson, both voiced by Roiland. It has aired for six seasons on Cartoon Network as part of the Adult Swim evening programming block, and has been renewed for a seventh.
Roiland also created the video game High on Life, described as a comedic alien shooter set in a science fiction world.
