Truth be told, there doesn't seem to be too much Barbie DNA in these purportedly "Barbie Edition" versions of the Avengers. They seem more like standard Marvel action figures, albeit ones that appear to be based on the film versions of the characters rather than their comic book or animated counterparts.
There's a slightly glammed-up Black Widow, followed by the aforementioned Thanos, who on second glance has hair that doesn't just evoke Ken but seems downright presidential. The Dr. Strange doll has his hands outstretched, presumably ready to perform some arcane gestures, while the Groot figure sits down to enjoy a plate of what appears to be either fruit or some sort of pastry. Gamora (Zoe Saldana) is up next, with an especially small amount of Barbie visual influence, followed by another Ken-like take, this one on Captain America (Chris Evans).
Iron Man, Black Panther, War Machine, and Loki come next, all with a dispiritingly low number of Barbie-esque visual signifiers. It would take a magnifying glass to find any pink at all in any of these images, and it's enough to make one question the utility of artificial intelligence software in creating the next generation of Barbie dolls and action figures.
