Tricia (last name unknown) was a human woman who gained green hair, yellow skin and pointed ears when Whistler's plague ball exploded. She was chased by people due to the way she looked, and came to Nadira's shelter because she was told she would be safe there. She was welcomed by Parker, who told her he went through the same sort of thing. The two became lovers. Although they were initially afraid of being excluded by society for their inter-species union, Nadira encouraged them to continue by helping them see that it didn't matter what other people thought.

She was later present during the battle against Archaeus and Drusilla trying to control the magic. Tragically, Parker died in her arms.
