Solar Opposites Season 4 Cast Guide: Who’s Replacing Justin Roiland When Korvo & Co Return

The Solar Opposites season 4 cast brings back some of the biggest names from the animated series, but there is also one major change that shakes up the entire show. Created by Rick and Morty co-creators Justin Roiland and Mike McMahan, the show is about aliens who ended up landing on Earth after their home planet was destroyed by an asteroid. These aliens then set up on Earth, pretending to be humans and fit in, all while ending up involved in crazed hijinks and extraterrestrial battles. Korvo and Terry, and their young replicates Yumulack and Jesse, along with their Pupa, have to figure out how to survive while growing closer as a family.
