Nier Automata game director Yoko Taro confessed in his latest interview that his whole idea for the character 2B was based off his love for cosplay.
Speaking exclusively to GameplayX, and translated from Japanese, Taro stated, “I have deep respect for those who have the passion to cosplay. I wanted to give pale skinned girls with delicious fat booties an opportunity to show off what their mother gave them without being judged or shamed.”

Quoted from the man himself.
