Argus Filch in Harry Potter and the Prisoner of Azkaban

Argus Filch

The mean Hogwarts caretaker, Filch is always on the lookout for students to punish. He had the Marauder's Map in his office, having confiscated it at some point. Fred and George Weasley relieved him of it in their first year at Hogwarts, though.
