Blue Eyes is a very intelligent chimpanzee, the prince of the Ape Colony in Muir Woods, and the eldest son of Caesar, who is the king of the apes. He has dark fur and blue eyes, unique among the green-eyed apes of the Ape Colony, though he was exposed to ALZ-113, a man-made cure for Alzheimer's. Blue Eyes is kind, but violent with those he sees a threat, and he cares about his family. He is naive at times, but he is generally mature. He has scars on his right shoulder from a bear attack.
