Nico Olvia

Nico Olvia (ニコ･オルビア, Niko Orubia) is Nico Robin's mother, an archaeologist 20 years ago. After her husband died, she set out on a six year journey in 1496 to research the Ponegylph. At the end of the 6th year in 1502, her ship was caught by the Marines. Her colleagues fought back to defend Olvia but were all killed except her, Aokiji would later use this situation to test the Straw Hat Pirates. Olvia was interrogated by Jaguar D. Saul. She was then set free by Saul who was disgusted by the World Government's Justice system and manage to get away with the Marine's ship.

Upon arriving at Ohara, Olvia went to the Tree of Knowledge library to warn her colleagues. After she failed to, she heared that the World Government ship has docked on shore. She went with an rifle on her hand. As she ran, she was aware that Robin ran past her on the oppsite way.
