Miro is the son and heir of the human leader Brun. He follows the traditions of the village without question, even when his girlfriend Talia is selected in the lottery to be handed over to the ape garrison as a slave. He is eventually persuaded by the astronauts to challenge his father by releasing the astronauts and Talia. When his father is killed, Miro says the slave lottery will end and he will ally with the other human tribes against the apes.

The character's name was "Trung" in early scripts.
