Judy Collins
Judy Collins was a human who travelled outside of her own timestream.
Judy traveled with the time traveller Yardley James for five years; they visited the 1700s and the planet Gweuk, and they participated in a bank robbery so Yardley could buy yellowcake. In a jail, they met a robot called Violet, who also joined them on their travels.
Judy spent three weeks in jail on Altos III for being Yardley's friend. Judy did another week in a cell in Longhorn for allegedly rustling cattle. Yardley finally dropped Judy off at home after discovering a terrible truth about the universe.
When the Jalaxian Empire invaded Earth, Judy was captured and imprisoned for being a temporal anomaly. Yardley helped her to escape, aided by Violet and her partner Enigma Tree. (PROSE: Judy's War)
