History Characters / AmericanDadRogerSmith

* DependingOnTheWriter: How people perceive Roger changes each episode sometimes people see as completely human sometimes people can see him as the oldly proportioned small gray man he is.

* PsychopathicManchild: A rare one indeed. He's a hybrid of types B, C, and E, and D too. Being an alien, he possesses a supernatural intellect [[DependingOnTheWriter and, on some occasions, physical aptitude (strength and/or speed)]], yet he uses these assets for very childish and simple purposes. He also possesses a lot of childish traits, such as his sweet tooth and his juvenile whining and complaining, and on a lot of episodes, Roger has been called a [[{{Manchild}} spoiled brat despite being a grownup]]. While he is very knowledgeable about this world, or better yet, life in general, he has committed a lot of heinous deeds during his unnaturally long lifespan and doesn't really see it as a big deal; committing a felony is the same as spilling a glass of water in his book (of course, [[MoralMyopia until it's inflected onto]] ''[[MoralMyopia him]]''), and while Roger might not appear as much, he is really a force to be reckoned with, to say the least.

* WouldHitAGirl: He slaps around Hayley and Francine a couple of times.

* MasterOfDisguise: Roger has an entire warehouse full of disguises and usually ends up disguised at least once (if not multiple times) per episode. Of course, many of his disguises are [[PaperThinDisguise Paper Thin]], but no one seems to notice, [[LampshadeHanging most of the time]]. Taken UpToEleven in "Steve, Snot, and the Quest for the Og 4Loko", where his disguises are shown to be so impossibly convincing that, when Steve and Snot borrow a pair, they not only appear to ''be'' those personas to everyone (including people who know them, except Roger himself), but ''show up on video as the characters''.

* MasterOfDisguise: Roger has an entire warehouse full of disguises and usually ends up disguised at least once (if not multiple times) per episode. Of course, many of his disguises are [[PaperThinDisguise Paper Thin]], but no one seems to notice, [[LampshadeHanging most of the time]].

* AmbiguousGenderIdentity: Roger identifies as a man by default, though he is incredibly gender fluid, acting as masculine or as feminine as whatever disguise he's wearing calls for, and he's also able to grow breasts. He also has the ability to impregnate others (both male and female humans) as seen in 'Deacon Stan, Jesus Man' and be impregnated himself as seen in 'Roger's Baby'. It's possible that Roger's species is hermaphroditic and capable of producing both male and female gametes.

* LaserGuidedKarma: Eventually, his heinous acts will end up becoming his undoing. Most of the time, it’s because Stan gets fed up with him and beats him to near-death.

* ForWantOfANail: "Persona Assistant" shows that Roger's multiple personas are what keep Langley Falls from falling apart.

* AllTakeAndNoGive: He expects others to bend ovee backwards to do things for him, yet he is often unwilling to perform even simple tasks or small favors for them without getting something in return.
