Najix

Najix is an alien who works for the Nerzod Productions and is the main producer of the hit intergalactic reality TV show Earth; which has made it to over one hundred episodes. He also has the ability to shape-shift from his original form based on the the thoughts of those around him. The boys get taken to the alien ship where the show is broadcast from in order to fix Cartman anal satellite probe; seen in the episode "Cartman Gets an Anal Probe", that happens to be only one of 500 on the planet used for documenting life on the planet. Najix tells the children that Earth is going to be cancelled due to a downturn in the ratings, which means Earth is going to be destoyed. The children meet with the Joozians, network heads of Fognl, to plead for then not to cancel Earth.

In an attempt to appear more appealing, Najix transformed into anything the boys can imagine. Cartman decided on the taco crapping ice cream. Others forms include:
 * Randy Marsh
 * Santa Claus
 * Saddam Hussein
 * Michael Jordan
 * Frank Sinatra
 * Don King
 * Mr. Roarke and Tattoo
 * Missy Elliot
