Cornelia was an evolved chimpanzee, the wife of Caesar and queen of the ape colony. She was a fellow inmate of Rocket, Maurice and Buck at the San Bruno Primate Shelter. She met Caesar during his stay at the shelter and formed a romantic bond with him. After Caesar's rise to power, she became his wife and bore him two sons, Blue Eyes and Cornelius. Because she was the queen of the ape colony, she was the matriarch of the Royal Ape Family. When humans are rediscovered, Cornelia becomes the ape counterpart of Ellie.
