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 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.
