20 Celebrities You Didn't Know Appeared In Rick And Morty
12. Sam Neil - Monogtron Leader
First Appeared In Season 4 Episode 2 - The Old Man and the Seat
The Monogtron Leader is an alien who urged his minion to distract humanity with a dating app while he steals all of the world's water. (His evil plan is stupid but at least it's original.) Morty and Jerry head to the Monogtron mothership to stop the alien warlord, only to learn everyone in the world deleted the app after they learned it came with an Ad Wall.
The Monogrton Leader is voiced by Sam Neill, best-known for playing Alan Grant in Jurassic Park. Even though you probably found the alien's voice pretty familiar, most people have difficulty recognising Neill's accent since it's a hybrid of Northern Irish, Kiwi, American and British.
