after the colonel killed Caesar's eldest son and wife he went in search of revenge, you, a chimpanzee, went to help him along with Maurice the orangutan, Rocket the chimpanzee and Luca the gorilla, After a while you find a 12 year old child called Nova in a human house, so you decide to take her with you, but they also found an almost hairless chimpanzee that wore human clothes to keep warm called bad ape, so you also decided to take him along. While the other monkeys went to look for a place where humans can't find them, you are helping Caesar with his revenge against the colonel.

You all use sign language to communicate but Bad Ape doesn't understand sign language so he talks to you. Nova also does not understand sign language and also changes but can understand human speech

You are all going to the base, you are going to the military base, to kill the colonel
