Emperor Zing

Emperor Zing is the main antagonist of the American Dad episode, "Lost in Space." He is the ruler of Roger's home planet. In "Lost in Space", after capturing Jeff with the intention of making him work in a shwarma stand on his ship, Jeff must prove to Emperor Zing that he was always in love with Hayley and win his freedom at the risk of losing his privates. Zing calls upon The Summoner to bring forth The Majestic to probe Jeff's mind. Taking the test, he finds he hasn't entirely treated Hayley well during his relationship. As Emperor Zing declare that he failed, Jeff protests that he really can love her right but they declare that he still lost. Moping at the slave camp, he is tempted to have one last night of sex before losing his privates but finds himself refusing to cheat on Hayley. Lowering himself into the pit, he faces The Majestic and complains that he only showed the bad memories with Hayley.

The Majestic reveals that his instructions are to only show the bad memories. They decide to start a revolution among the slaves when Jeff is about to lose his privates and reveals the Emperor’s treachery to all of the slaves. With Sinbad's help, Jeff makes his way to an escape pod as The Majestic reveals the Emperor's own love life that was ruined by Roger when he cheated on him. The emperor is last seen being pelted with objects thrown by his audience, and it is unknown what happened to him after that.
