A sequel to Kingdom of the Planet of the Apes is already being planned, and here are 10 classic villains from the franchise who could return in Kingdom of the Planet of the Apes 2. Throughout the Planet of the Apes franchise, all kinds of iconic villains have been introduced, each with their own plan to take over Earth for humankind, apekind, or mutantkind. Since there are only four movies in the modern Planet of the Apes saga, plenty of classic villains still haven’t returned, but they could finally appear in Kingdom of the Planet of the Apes 2.
