Lucius Malfoy

"I assure you, my Lord, I have never renounced the old ways. The face I have been obliged to present since your... absence...that is my true mask."

- Lucius to Lord Voldemort in Harry Potter and the Goblet of Fire.

Lucius Malfoy is one of the major villains in the Harry Potter series. He is a Death Eater and the father of Draco Malfoy, Harry Potter's school enemy. He is portrayed by Jason Isaacs, who was also the voice of Ra's Al Ghul in Batman: Under the Red Hood, Satan in Castlevania: Lords of Shadow and at one point Captain Hook in the 2003 Peter Pan film.

Chamber of Secrets
Lucius first appeared as a main antagonist ( along with Tom Riddle) in Harry and the Chamber of Secrets, where he slipped Tom Riddle's Diary to Ginny Weasley - causing the release of the Basilisk - forced the Ministry to fire Dumbledore and Hagrid and tried to discredit his rival Arthur Weasley. He was defeated after Harry tricked him into freeing Dobby from slavery and Dobby blasted him away in self-defence.

Goblet of Fire
Lucius appears at the beginning of Goblet of Fire when he attends the Quidditch World Cup with Draco and Narcissa. In the climax, Lucius is revealed to be a Death Eater who works closely with Lord Voldemort and is seen on the night of his return with other Death Eaters.

Order of the Phoenix
Lucius is seen in Order of the Phoenix as one of the Death Eaters who were sent to retrieve a special prophecy that was about Voldemort and Harry Potter. He leads the group that consists of himself, Bellatrix Lestrange, Antonin Dolohov and a few other unnamed Death Eaters. After unsuccessfully retrieving the prophecy, he is seen fighting members of the Order of the Phoenix and is stunned by Sirius Black, who is killed moments later by Bellatrix. He is sent to Azkaban at the aftermath of the battle

Deathly Hallows
escapes in Harry Potter and the Deathly Hallows, in which he lends his house to the Dark Lord as his headquarters. When Voldemort and the Death-Eaters came to Hogwarts for the final battle, Lucius came along too along with his wife. Because Lucius' wife, Narcissa, lied to Lord Voldemort about Harry Potter being dead and it helped Harry to defeat him, the Malfoy family could use this to get a pardon.
