The Zigerions are humanoid aliens with four arms with a pink to purple skin tone. They have elongated heads with a small number of spiky protrusions. They also have long antennae-like appendages that could serve as their ears. They are outfitted with a specific type of space uniform that bears resemblance to the Star Fleet uniform in Star Trek.
The Zigerions are known for their deceptive tricks and scamming tendencies. Rick stated that they have been after his recipe for concentrated dark matter for years. The race lives on a large spacecraft that is outfitted with a wide variety of advanced technology, including several machines able to create realistic simulations. While their simulations can generate a life-like environment, the artificial intelligence of the simulated individuals can often be unrealistic. While Rick was always aware of being in a simulation, Jerry was completely unaware.
The Zigerions apear to suffer from Gymnophobia the fear of nudity, and it also seems to affect the whole race. Rick takes advantage of this order to stay unmonitored. However, thanks to the efforts of the Zigerion Kevin, they were able to create a simulated, nude Morty which (nearly) fooled Rick.
On "Arrested Development", the character played by David Cross, Tobias Fünke, was a "Never Nude" syndrome sufferer and wore a pair of tight jean cutoffs under his clothes.
- The Zigerions and their gymnophobic scammer personality may be a reference (and homage) to the nudist scammers in Futurama, another Space-oriented comedy.
