ZombieCleo, known as Cleo for short, is a YouTuber and member of the Hermitcraft server. They joined at the start of Season 2 after being invited by JoeHills. They are trained as a high school science teacher, and have also taught primary school-aged students with both a kindergarten class and a year 6 class. While some of their students watch Hermitcraft, none knew the online identity of their teacher. She wastes no breath making snarky comments to everyone on the server.
