Skull-Head
Skull-Head was the male alpha of Skull-Head's troop, the largest single troop of monkeys in Monkey Hill and one of the largest monkey troops in the world (with over 300 members), for over 20 years. As a result, he was well-known to humans, even appearing on the cover of a government brochure for Monkey Hill.
Skull-Head was deposed as alpha in late 2021, by then an elderly monkey. However, he was able to remain in the troop, and lived out the rest of his days as a high-ranking male in the troop that bears his name. Even after his ouster, he was still well-respected in the troop, with many high-ranking members still offering fear grimaces and presenting their bottoms (both signals of submission) whenever he passed by.
Despite his name and ferocious look, Skull-Head was quite amiable and approachable, and dealt well with humans. He treated monkey babies with gentleness and care.
Skull-Head passed away on May 14, 2022.
