Zilo is a gorilla soldier, a loyal follower of Zandar and of Urko. He guesses correctly that Gregor is the human that has been spotted riding horses in the area. He helps plant the traps that ensure Urko wins all his races, but he is stopped from shooting Virdon, to prevent him winning, when Galen places a scorpion on his shoulder.
