Lucius Malfoy

Current head of the Malfoy family, Lucius Malfoy is one of Harry Potter's greatest enemies. High up in the Death Eaters before the fall of Voldemort, Malfoy managed to convince enough people he had not been acting of his own free will and suffered no reprisals. We must assume that Lucius Malfoy is extremely adept at swaying the minds of others, for even Lord Voldemort accepted him back following Voldemort's rebirth. Lucius Malfoy was responsible for all the terrible events in Harry Potter and the Chamber of Secrets, as he was the one who gave Riddle's diary to Ginny Weasley. In Harry Potter and the Order of the Phoenix, Lucius Malfoy leads the Death Eaters who chase Harry and the DA through the Department of Mysteries.
