The 100-Series Observational Realians were a series of artificial humanoids in the Xenosaga series. They all had the appearance of a young girl with light skin, light Blue Hair, and yellow or Brown Eyes.
They were the successor series to the 99-Series Realians and were modeled after their prototype, MOMO Mizrahi.
