Greer changed her name and had her sexual reassignment surgery at the age of 21, which was paid for by her father's church. Gender and sexuality are recurring themes in her art. Her dolls are created in the likeness of those society calls "freaks", and have often been compared to the surrealist works of Hans Bellmer, who made surreal dolls with interchangeable limbs. She created figures that were simultaneously distressing and glamorous, as if they were both victim and perpetrator of their existence.
