Testamonica, also known as Monica, is the chairman of the Galactic Criminal Police Organization (GCPO), which has its headquarters on planet Alesta.
Monica is a large woman with animal-like ears, big breasts, and a braided ponytail.
Monica was one of the girls that Volk picked up on planet Alesta during the flirting contest. Volk got her phone number. Posing as a girl, Geralt began communicating with Monica in order to find information about building or acquiring a time machine. They became friends and Geralt fell in love with her. Monica decided to break off communication with Geralt, saying that her work won't allow her to communicate with people outside of the planet. However, she promised to find Geralt one day.
After breaking off communication, Testamonica vows to take down Geralt of the Qarakhasan space pirate gang, unknowing that this is the same Geralt that she had been communicating with.
