[2][3] He had also voiced Earl of Lemongrab in Adventure Time, Blendin Blandin in Gravity Falls, and Oscar in Fish Hooks.

[8] In 2002, Roiland moved to Houston, Texas and, in 2004, got involved with Channel 101, an L.A. media collective started by Dan Harmon and Rob Schrab, where he made and acted in numerous movie shorts (such as 2 Girls One Cup: The Show, House of Cosbys and a small role as musician Christopher Cross in the series Yacht Rock) and in the VH1 television show Acceptable TV.

On August 25, 2016, Roiland launched virtual reality studio Squanchtendo, a portmanteau of the company Nintendo and Rick and Morty character Squanchy.

[21] In August 2020, Roiland was arrested and charged with felony domestic battery and false imprisonment in Orange County, California, in connection with an alleged incident in January 2020 involving an unnamed woman he was reportedly dating at the time.

[24][25] After the charges were announced, multiple people came forward with their own allegations of abuse by Roiland in the #MeToo movement, including claims on Twitter of predatory behavior towards minors.

"[28] Earlier, he had been accused of sexual harassment of a female writer on the third season of Rick and Morty and other uncomfortable behavior in the workplace; these claims were formally investigated by Cartoon Network and Adult Swim in 2020 and were not reported until 2023.

[28][29] Adult Swim announced later that month that Roiland had been dismissed from Rick and Morty, and that his roles would be recast for future seasons.

[30] On January 25, 20th Television Animation confirmed that he had also been removed from Solar Opposites and Koala Man, which will also continue to be produced without his involvement.

He released a statement on social media saying he is "determined to move forward and focus both on my creative projects and restoring my good name".
