So Sasha was actually a life sized doll brought to life. She was made to be about the same size as a teenage girl (even tho she's 18). Her creator brought her to life, thinking that the children would like to talk to a living doll. But society had different plans. They all stated that Sasha and her kind was dangerous, but her creator didn't care. So he made more dolls like her. But then an incident occurred when one of the other dolls went crazy and burned down a house, and the doll was discontinued. The creator destroyed the other dolls, but Sasha survived. She escaped the incinerator through the window. A few days after she escaped however, her creator got arrested for child endangerment (he went crazy and started to make killer toys). So yeah, she's literally the last of her kind.
