Lucilla was a gorilla from Ape City, the daughter of Marcus, eight years before Taylor's arrival. When the chimp Timon arrived in Ape City preaching the word of Aleron, he found a willing follower in Lucilla, who took to wearing the eyepatch emblem of Aleron's disciples. To help spread the message, Lucilla even agreed to use her voice to make it seem as though the human girl Pin was talking during Timon's addresses. She was beaten by gorilla soldiers when Ursus broke up one of their meetings, and fled with Timon, Cornelius and the injured Pin, but returned to Ape City to implore her father to prevent a war among the ape factions.
- Lucilla is exclusive to the continuity of the Planet of the Apes comic books published by BOOM! Studios.
