>>5310122even their animation is a mess.
You have a lot of the basic doll advertisement animation specials, which don't really have a canon. They haven't been related since the 80s.
You have LITD, which is supposed to star animated dolls, and largely refers to the history of the toys themselves, while making everyone act like an escaped mental patient. It also seems to be a bit self-depreciating, acknowledging that Barbie has had many careers yet letting us think she's unskilled at anything but runway modeling. They made a big deal out of her just getting a driver's license even though she was a racer at some point before.
The recent video blogs treat her as a living person, but she's a teenage girl.
The dolls themselves have never had a consistent canon. 60s Ken had a hunting outfit with a rifle, for fuck's sake. Names are changed due to lapsed trademarks, characters aren't much consistent in name or appearance, if they get a name at all.
