~ Caesar describes the dreadful past Koba suffered. From humans.Koba learned hate (hatred).but nothing else. In Dawn of the Planet of the Apes and War for the Planet of the Apes, he was voiced/portrayed by Toby Kebbell in motion capture, who also played Doctor Doom in Fant4stic and Drake Stone in The Sorcerer's Apprentice. In Rise of the Planet of the Apes, he was voiced and portrayed by Christopher Gordon in motion capture. While initially a tragic character and a compassionate friend towards Caesar, over time Koba's misanthropy corrupted him, turning him into little more than a hypocritical tyrant. Harboring a vendetta against humanity for torturing him in the past, he betrays his former friend and ultimately plots to eradicate mankind, with or without the support of his fellow apes going far enough to endanger the ape colony altogether. He was formerly the right-hand advisor and brother-in-arms-turned-archenemy of Caesar. He is an aggressive, dangerous, vengeful, and violent Bonobo ape who is considered to be an evil counterpart to the main protagonist Caesar, whom he formerly respected. He is a supporting character in Rise of the Planet of the Apes, the main antagonist of Dawn of the Planet of the Apes, and the posthumous overarching antagonist of War for the Planet of the Apes. Koba is the main antagonist of the Planet of the Apes reboot trilogy. ~ Koba appears to Caesar as a hallucination, taunting his friend-turned-enemy on his apparent failures to save the ape colony.
