Draco Malfoy's father and a prominent Death Eater. A rich man, Mr. Malfoy is well connected at the Ministry because he often gives money to charitable causes. Nobody outside of the Order of the Phoenix suspects him of being a Death Eater, however. Harry believes correctly that Mr. Malfoy is trying to figure out how to get into the Department of Mysteries at the Ministry, and it's implied that he's the one who placed Imperius charms (mind control) on Broderick Bode and Sturgis Podmore. He takes the lead in trying to negotiate with Harry when Harry and his friends go to the Department of Mysteries themselves, and Mr. Malfoy and his cronies are sentenced to time in Azkaban prison when Dumbledore catches them.
