The aliens of Solar Opposites are set for their last mission.

Hulu announced Tuesday that the forthcoming sixth season of Solar Opposites will be its last. The final episodes of the animated series are scheduled to premiere in the fall, with a specific date to be announced later.

The show has also lined up a guest cast for the final season that includes Tiffany Haddish, Kieran Culkin, Christina Hendricks, Ken Marino, Alfred Molina, Natalie Morales, Jerry OConnell and Beck Bennett. They join regulars Dan Stevens, Thomas Middleditch, Mary Mack and Sean Giambrone.

Stevens joined Solar Opposites in season four, when he took over the voice role of Korvo from series co-creator Justin Roiland, whowas oustedfrom the show in the wake of domestic violence allegations. Charges were later dismissed due to insufficient evidence to prove the case beyond a reasonable doubt, the Orange County, California, district attorneys office said.

The final season will feature the usual chaotic behavior from Korvo, Terry (Middleditch), Jesse (Mack) and Yumyulack (Giambrone), all while the final chapter of an epic drama unfolds for the shrunken people theyve imprisoned in their Wall, according to the season logline.

Solar Opposites is produced by 20th Television Animation. Mike McMahan, Josh Bycel and Sydney Ryan executive produce.
