Peeves was a poltergeist at Hogwarts. Fond of mischief and chaos, he was a constant pain to the school and its inhabitants, especially Argus Filch, with the only ones being able to control him being the Bloody Baron and Professor Dumbledore. In 1995, Peeves, along with most of the Hogwarts residents, opposed Professor Umbridge, the High Inquisitor, and pranked her until she was kicked out of the school at the end of the school year. In 1998, Peeves fought at the Battle of Hogwarts against Lord Voldemort and his Death Eaters. After the battle, Peeves continued making trouble at Hogwarts.
