- “Oh, this is going to be such a mindf**k!”
- —Prince Nebulon[src]
Prince Nebulon was the leader of the Zigerions in Rick and Morty. He appears as the main antagonist in M. Night Shaym-Aliens!. He has a long-standing grudge against Rick and is committed to stealing the recipe for concentrated dark matter from him. He is apparently concerned with discoloration of his butthole flaps.
He drafts a plan to abduct Rick into a simulated reality in order to trick him into giving up the formula. He employs Kevin to research human nudity in order to create a convincing Morty to help bring Rick's guard down. Despite putting Rick through several layers of simulations, he was tricked by Rick into blowing up the entire Zigerion spaceship.
After tricking the Zigerions by giving them the wrong ingredients for concentrated dark matter, their entire spaceship explodes.
- Prince Nebulon and the Arrested Development character Tobias Fünke, also played by David Cross, both share an aversion to nudity. In Arrested Development Tobias has a condition called "never-nude syndrome" where he wears cut-off jean shorts underneath his clothes so that no one, not even himself or his wife, can see him nude.
- Along with Jerry's voice actor Chris Parnell, David Cross is the second voice actor featured in Rick and Morty to have appeared in Archer. Parnell voices comptroller Cyril Figgis, and Cross voices anthropologist Noah.
