Different versions of the characters (including the bespectacled genocider, President Morty Smith) inhabit other dimensions throughout the show's multiverse, with their personal characteristics varying from one reality to another.

They encounter Mr. Nimbus, who explains the sword seals the dark energy and fighting spirit of the planet inhabitants at the beginning of the series.

The short stars Yōhei Tadano as "Rick WTM-72" and Keisuke Chiba as "Shogun Morty", the pair reprising their roles from the Japanese dub of the animated series.

[citation needed] Another eight-minute short film titled Rick and Morty vs. Genocider aired unannounced on Toonami on July 26, 2020, debuting on YouTube slightly after.
