Hypnovision

Hypnovision is a form of subliminal advertising used by Robotnik in the episode Sonic is Running. Along with his Robowife and Robodog, it was used to help Robotnik gain support in his campaign election.

History
The Hypnovision was first used in the Robotnik commercials to gain support in order to defeat his rival Henry Walrus. Sonic while watching it from Bert's Diner was unaffected by the commercials as he was fast enough to see through the hypnosis spiral. However he learned the hard way that the Hypnovision causes its victims to lash out at anyone who insults Robotnik as the customers in the diner (including Bert and Roxy) chased him out by throwing utensils and food at him. This event leads Sonic to run for president himself.

The Hypnovision however has a flaw; if the victims are insulted by the person they support or if that same person causes a disaster of epic proportions, the Hypnovision will wear off. It was this flaw that Sonic used to defeat Robotnik and help him gain support to win.
