Roger's disguises on American Dad are without a doubt one of the best aspects of the show. He’s been everything from Lord of the Rings’s Gollum to a Bond Villain. The Roger Smith personas are a necessary part of his existence, since he is an alien after all, he can’t very well go out and mingle with the general public. Things have definitely evolved from "Roger the alien in disguise" to the disguises becoming an integral part of Roger’s personality.
Very little is known about his past. Viewers know he landed in Roswell years ago and his only mention of his parents was that his mother suffers from arthritis and he wishes she could figure out Skype. Apparently, he ate his father at 14 years old and he still has bits of his leg. Roger’s many fictitious identities have contributed to his journey of discovering what his true identity is now… even if that means exploring what it’s like to be a Jacuzzi salesman that smokes crack out of a Rubix Cube. Keep reading for some of Roger's best disguises on American Dad.
