20 Celebrities You Didn't Know Appeared In Rick And Morty

First Appeared In Season 1 Episode 4 - Shaym-Aliens!

Prince Nebulon is an alien leader obsessed with obtaining Concentrated Dark Matter. When he learns Rick is in possession of this material, Nebulon has him imprisoned until he tells him the recipe.

If you were wondering why Nebulon's squeaky way of speaking sounded familiar, it's because the Zigerian overlord was voiced by David Cross. Cross is best-known for portraying Tobias Funke in the tv series, Arrested Development. Weirdly, both characters have a phobia with nudity. Funke is a self-diagnosed never-nude and Nebulon is self-conscious of his buttflap's discolouration. (It's a pretty thing to be typecast as.)

Nebulon only made a single appearance but has become one of the most memorable villains thanks to Cross' impeccable line-delivery and comic timing.
