Koba

Koba is a major recurring antagonist of the Planet of the Apes reboot franchise, starting off as an anti-hero in Rise of the Planet of the Apes, the main antagonist of Dawn of the Planet of the Apes, and a posthumous antagonist in War of the Planet of the Apes.

He is an aggressive, dangerous, vengeful, and violent Bonobo ape who is considered to be a dark counterpart to the main protagonist, Caesar, whom he initially respected.

He was formerly the right-hand adviser and brother-in-arms of Ceasar, but later betrayed him upon harboring a vendetta against humanity for tormenting him in the past and ultimately plots to wipe them out with or without the support of his fellow brethren; thus going as far enough to endanger the ape colony altogether.

In Rise of the Planet of the Apes, he was voiced by Christopher Gordon in motion capture, and later by Toby Kebbell in Dawn of the Planet of the Apes and War for the Planet of the Apes, who also played Doctor Doom in Fant4stic and Drake Stone in The Sorcerer's Apprentice.
