Rick Sanchez (Rick and Morty)
He is formally referred to as Rick Sanchez C-137 (alias: "Terror Rick") by the Trans-Dimensional Council of Ricks, in reference to his original universe, "C-137", and penchant for instigating wars with inter-galactic empires. Both Rick and Morty are voiced by Roiland. Volume 1 of the "Rick and Morty" comic series follows the Rick and Morty of Dimension C-132 while most issues of subsequent instalments follow the Rick and Morty of "C-137"; the video game "Pocket Mortys" follows the Rick and Morty of C-123.
Run the Jewels
In March 2018, Adult Swim released a Run the Jewels/"Rick and Morty" crossover music video for "Oh Mama". The music was a remix of "Oh Mama" from "Run the Jewels 3" accompanied by sound effects from a "Rick and Morty" short. The effort was directed by Juan Meza-León, and was released prior to Run the Jewels headlining the 2018 Adult Swim Festival on October 7, 2018.
