Io Jasper was a female resident of the Capitol and a student of the Academy. She was one of 24 top-performing seniors at the Academy selected to be a mentor for the 10th Hunger Games. She was assigned the male tribute from District 3, Circ.
She was a natural when it came to biology and partnered with Coriolanus Snow at the high biology class at the Academy. Coriolanus felt that the she must have been born with a microscope attached to her eye. He hated working with her, but nevertheless behaved graciously around her, resulting in her adoration.
Her parents were scientists of some sort. Her tribute, Circ, died after being bitten by snake muttations sent into the Capitol Arena by Dr. Volumnia Gaul. Snow regretted the loss of her presence, as she tended to be clinical rather than combative.
- Io was one of the many mortal lovers of Zeus, the chief god of the Greek pantheon.
