Jinzouningen 18-gou

人造人間18号
Jinzouningen 18-gou is a cybernetic human, modified by Dr. Gero. She is often referred to in the original Japanese as a jinzouningen, which literally translates as "artificial human." She is not entirely an android; she refers to both herself and her twin brother as having been "constructed from a human base." (Source: Wikipedia)
