Solar Opposites


Solar Opposites is an American adult animated science-fiction sitcom created by Justin Roiland and Mike McMahan for Hulu.
Originally created for the Fox Broadcasting Company, the project was shelved before being acquired by Hulu. The series premiered on May 8, 2020, and concluded on October 13, 2025, after six seasons consisting of 63 episodes.

Premise

Solar Opposites centers around Korvo, Terry, Jesse, and Yumyulack — a family of aliens who crash land on Earth and are forced to stay there, often disagreeing on whether this is a good thing. The family comes from Planet Shlorp, an advanced alien world that sent out one hundred ships — each carrying 2 adults and their replicants — to colonize new planets shortly before their home planet was destroyed by an asteroid.
The series also features parallel storylines, the most prominent of which follows a society of humans shrunk by the replicant Yumyulack and imprisoned in a terrarium known as "the Wall". Starting in the third season, another storyline follows a group of intergalactic corrupt police officers, known as the SilverCops, that routinely arrest and brutalize Shlorpians fleeing from the destruction of their homeworlds.

Production

Development

On August 28, 2018, it was announced that Hulu had given the production a two-season order consisting of sixteen episodes. The series was created by Rick and Morty co-creator Justin Roiland and Mike McMahan, who were also expected to serve as executive producers. It is distributed by 20th Television.

Writing

The Wall in Yumyulack's room where he imprisons shrunken-down people was, as Roiland has noted, one of the duo's initial ideas for the series, as they were interested in a "B-story" that lasted the entire first season.

Casting

Both shows are distributed by 20th Television, via their 20th Television Animation division. On June 20, 2023, it was announced that Dan Stevens was officially taking over as the voice of Korvo.

Dan Fienberg of The Hollywood Reporter praised the animation of the series, acclaimed the performances of the voice actors, and complimented the humor of the show, writing, "Justin Roiland and Mike McMahan's new Hulu animated comedy Solar Opposites has enough loopy sci-fi elements to appeal to Rick and Morty fans and a distinctly adult sensibility." Alison Foreman of Mashable praised the dynamic and strong relationships between the different characters, drawing comparisons with other families coming from adult animated sitcoms such as The Simpsons while complimenting the humor of the show, calling it a "spectacular gem worthy of its own fanbase." Joe Matar of Den of Geek rated the series 5 out of 5 stars, praised the show for its classic sitcom format, acclaimed the performances of the voice actors, and applauded the comicality, stating that despite the comparisons with Rick and Morty, the series manages to stand on its own. Alex McLevy of The A.V. Club gave the show a B grade and called it "a mischievous cousin of 3rd Rock from the Sun" while saying it doesn't stray too far from the template Roiland set with Rick and Morty. McLevy feels the show is still finding its feet, but "Luckily, the humor is so reliably strong, the pacing so breakneck as it races from one plot to the next, that it's hard not to be won over by Solar Opposites avalanche of charm." Joyce Slaton of Common Sense Media rated Solar Opposites 3 out of 5 stars, writing, "Solar Opposites is an animated show by the brains behind Rick and Morty. It has the same style and vibe, including lots of edgy humor, cheerful gory violence, surreal visuals and plot twists, and wall-to-wall language."
