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.
