Po's mother was a giant panda who was the wife of Li and the biological mother of Po.
She was killed during the massacre of her home village by Lord Shen and his wolves. Her only appearance has been in the memories and dreams of Po in Kung Fu Panda 2. Her name is currently unknown.
Po's mother seemed to have a warm, caring nature, and appeared smiling while living her peaceful life with her family in the panda village.
During the attack on their home, she acted swiftly and took her cub, fleeing without question as her husband held off the invading wolves.
She showed an undeniable maternal love for Po when she eventually chose to leave him in a crate of radishes for safekeeping, willfully catching the attention of the wolves to follow her alone and sacrificing her life to save his.
