Peeves is the poltergeist of Hogwarts who has been around the school since it was founded. “Peeves is the most notorious and troublesome poltergeist in British history. Unlike the overwhelming majority of his colleagues, Peeves has a physical form, though he is able to become invisible at will. His looks reflect his nature, which those who know him would agree is a seamless blend of humour and malice.”
