10 Craziest Fan Theories About American Dad

10. Avery Bullock Is Susie Swanson

Family Guy and American Dad have consistently showcased that they are within the same universe. This would indicate that Stan Smith, Avery Bullock and the CIA as depicted in American Dad exists within the Family Guy universe. As discussed by WickedBinge, it is highly possible that Susie Swanson (the daughter of Joe and Bonnie) is actually an avatar from the CIA used by Avery Bullock.

In American Dad's seventh season episode titled Virtual In-Stanity, (Season 7, Episode 5) the show explores the CIA's use of avatars. Avatars are motion controlled by the CIA, with Bullock even revealing that one of his avatars is a baby that he poses as for personal reasons.

While that may not be enough to believe the theory to be true, the voice of Susie's inner monologue is none other than Patrick Stewart, who also voices Avery Bullock. It also is not very hard to believe then that Bullock would have more than one baby avatar to utilise in order to meet his sexual desires.
