Patricia Walker was born to a low income family. After her father left her mother, Dorothy Walker began putting her daughter through acting school, which would later land Patricia the role in the TV show "It's Patsy", making her the most famous child star in the world at the time. For a publicity move, Patricia's mother adopts a classmate of Patricia's who has been in a car accident, making Jessica Jones her adoptive sister.
In her adult years, Patricia reinvents herself as "Trish Walker", trying to wash away her teen star years, running a talk show by the name of Trish Talk.
Trish is endlessly supportive and true friend. She always has the best interests of her best friend at heart, even if the situation between the two of them becomes strained.
She has an impulsive side, with a personal mission to make herself strong enough so as she can protect herself from the dangers of the world, and be a hero like how she knows Jessica is.
- "Patsy Walker" was created by writer Otto Binder and artist Ruth Atkinson in Miss America Magazine #2 (Nov. 1944). Alongside Namor the Submariner, and Captain America, Patsy is one of Marvel's oldest characters. In universe, she would later take on the mantle of "Hellcat", joining The Avengers, and would later become a founding member of The Defenders.
