10 Craziest Fan Theories About American Dad
4. All The Characters Are Roger Personas
According to Reddit user u/The_FactSphere, Roger is in fact every character in the show, as they are all his personas. The user argues that while the audience does not see this due to being an outside perspective, they believe that all the characters were unleashed after a traumatic event.
This event is in fact Roger destroying all life on Earth, hence why his spaceship cannot destroy all life on Earth in "Weiner of Our Discontent (Season 4, Episode 18), where Roger revealed that he was sent to Earth as 'The Decider' who was tasked with deciding whether humanity should live or perish. Roger believed he could end all life on Earth in the episode due to his psyche blocking any knowledge of destroying all life on Earth from due to the trauma it caused him.
Even the creator of the theory admits it is a bit of a stretch, however it is one of the more outlandish theories from the series and would certainly take the show in a dark direction if proven true.
