Draco Lucius Malfoy was a pure-blood wizard and the only son of Lucius and Narcissa Malfoy, née Black. The son of a Death Eater, Draco was raised to believe strongly in the importance of blood purity.
He attended Hogwarts School of Witchcraft and Wizardry and was sorted into Slytherin House.
During his years at Hogwarts, he became friends with Vincent Crabbe, Gregory Goyle, Pansy Parkinson, and other fellow Slytherins, but he quickly developed a rivalry with Harry Potter.

Draco was a slender boy with sleek white-blond hair, cold grey eyes, a pale complexion and rather sharp, pointed features. He was described to have haughty good looks. As an older man, his hairline was receding, making his features look even more pointed.
In his first and second years he had blonde hair slicked tightly back. Draco is noted to strongly resemble his father. When Draco joined the Death Eaters, Lord Voldemort had the Dark Mark burned into his left forearm, which has since faded to a mere scar upon Voldemort's death.
Draco was, in general, an arrogant, spiteful bully. Like Dudley Dursley, his narcissistic nature most likely stemmed from his being spoiled by his parents throughout his childhood, though according to Harry himself, Draco is even less sympathetic than his cousin.
He believed himself superior to most people because of his family's pure-blood lineage as well as great wealth and social standing. He frequently behaved cruelly to Muggle-borns, so-called blood traitors, Gryffindor students, and anyone who was a supporter of Harry Potter or Albus Dumbledore.
For much of his youth, Draco took after his bigoted father, Lucius Malfoy, as a role model, and frequently boasted about his family's influence and wealth.
During the first five years of school Draco maintained a relatively healthy look. However, in his sixth year onward, when the stress of his mission was getting more intense, Draco's smug countenance was lost, and he became quite thin, with dark shadows under his eyes and a greyish tinge to his skin.

As an adult, Draco let his hair grow long and started wearing it in a precisely placed ponytail.
He was made a prefect of his house and was a member of the Inquisitorial Squad during his fifth year, at the end of which his father was imprisoned in Azkaban following the Battle of the Department of Mysteries.
Lord Voldemort charged Draco with making up for Lucius's failure, and he became a Death Eater at age sixteen, but was quickly disillusioned with the lifestyle. Draco was unable to complete his task -murdering Albus Dumbledore, which was taken over by Severus Snape- and only performed his other duties fearfully and reluctantly. He and his family defected hours before the end of the Second Wizarding War fearing for their lives.

Draco was raised in an atmosphere of regret that the Lord Voldemort had not succeeded in taking command of the wizarding community, although he was prudently reminded that such sentiments ought not to be expressed outside the small circle of the family and their close friends or Daddy might get into trouble.
The Malfoys were very proud of their Pure-blood and social status; they were able to maintain a respectable public image while being allied with Lord Voldemort.
Lucius was a Death Eater who avoided imprisonment in Azkaban following the First Wizarding War by claiming that he have been under the Imperius Curse, while Narcissa merely agreed with the ideology of pure-blood supremacy.
The Malfoys spoiled their son, giving him the best of everything as far as material possessions go. The only two hand-me-down things Draco ever received were the old family prejudice against Muggles, Muggle-borns, half-breeds, and blood traitors -in short, prejudice against anyone who was not a pure-blood wizardkind, or anyone who supports these types of people- and the Malfoy family's waste collection of powerful dark artefacts harking back to the family history.
In childhood, Draco associated mainly with the pure-blood children of his father's ex-Death Eater cronies, and therefore arrived at Hogwarts with a small gang of friends already made, including Theodore Nott and Vincent Crabbe.

When the time came for Draco to attend school, his father wanted him to attend Durmstrang Institute, a school in Northern Europe that taught the Dark Arts and did not admit Muggle-borns. However, his mother did not like the idea of Draco going to school far away, thus they sent him to Hogwarts.
When Draco went to Diagon Alley to shop for school supplies, he met Harry Potter in Madam Malkin's Robes for All Occasions, without knowing who he was. He made a rather intolerant speech about Muggle-borns and Rubeus Hagrid, but otherwise acted in quite a friendly manner towards Harry Potter.
Afterwards, on the Hogwarts Express, he offered his friendship to Harry as his father believed that Harry was a Dark wizard, and Draco wished to impress him and relay some interesting news home.
However, Harry didn't like the attitude Draco expressed towards Ron Weasley, with whom Harry had already made friends, and also found that Draco reminded him of his cousin Dudley, with his disdainful attitude. Thus, he turned him down, creating animosity that lasted through the rest of their schooling.

Once at Hogwarts, Draco was Sorted into the Slytherin House, like many other members of his family. He rapidly formed friendships with fellow Slytherins, while remaining hostile toward Harry to the point of challenging him to a duel.
This was, in fact, an attempt to get Harry into trouble for being out after curfew. He resented the attention Harry received because of his fame and his prodigious flying ability, which led to Harry being permitted to join his house's Quidditch team at a younger age than most.
In his second year at Hogwarts, Draco attained the position of Seeker on the Slytherin Quidditch team. His father bought the entire team new Nimbus 2001s because of this, though Hermione Granger openly speculated that this was in fact what got Draco on the team at all.
Draco responded angrily to this accusation, and called Hermione a filthy little Mudblood, causing the Gryffindor Quidditch team to lash out at him; Ron tried to hex him to vomit slugs, but the spell backfired due to his broken wand.
Draco started off his third year by mocking Harry's reaction to the Dementors that were near Hogwarts that year searching for escaped Azkaban prisoner Sirius Black, despite being terrified of them himself. He also hinted at Black's crimes regarding Harry and his late parents, which Harry was unaware of for some time, and told him that if someone had betrayed and gotten his parents killed -as it was believed Black had done to the Potters- he would seek revenge.

Draco became a Slytherin prefect along with Pansy Parkinson. He was sure to mock Harry Potter for not receiving the same honour, as Gryffindor's prefects were Hermione Granger and Ron Weasley. He also wrote the lyrics to the demeaning song Weasley is Our King, which mocked Ron's Quidditch abilities as Gryffindor Keeper.
It was the invention of this song, as well as insulting Molly and Arthur Weasley and the late Lily Potter to Harry, Fred, and George's faces that prompted Harry and George to get into a fight with Draco.
They violently assault him, which resulted in the pair, as well as George's twin brother Fred, being banned from all further Quidditch matches. Although their bans were later lifted after Dolores Umbridge's sacking from Hogwarts and her being put on suspension for her actions.
Draco's father was seen participating in the battle as a Death Eater and was imprisoned in Azkaban for his crimes. Draco was very upset by this, and mainly blamed Harry, swearing vengeance and attempting to attack him at the end of the school year with the help of Vincent Crabbe and Gregory Goyle. However, other D.A. members came to Harry's defence, resulting in Draco, Crabbe, and Goyle ending up looking like ugly slug-like things after being hit by a number of hexes by all D.A. Members at the same time.

Draco joined the Death Eaters, having replaced his incarcerated father. He bragged about having been given a mission to his fellow Slytherin students on his way to school on the Hogwarts Express.
However, as the year dragged on, Draco became increasingly afraid that he would fail in his seemingly impossible task -to kill Albus Dumbledore. It is implied that Draco was expected to fail and that Voldemort assigned him the task with the intention of punishing Lucius Malfoy for his failure at the Department of Mysteries.
The safety of his family rested on Draco's success with his mission. When Harry overhead some parts of Draco's conversation with his fellow Slytherins about the mission, Draco used a Full Body-Bind Curse to paralyse Harry and stomped hard on his face, crushing his nose, in revenge for imprisoning his father, Lucius, causing Harry to hate Draco more than ever, while disregarding what Harry heard as not important enough to condemn him.
Draco reluctantly participated in Death Eater activities before the beginning of the school year. Due to Draco's helpful role in Dumbledore's death, Voldemort liberated Lucius from Azkaban. He witnessed the murder of Charity Burbage and tortured Thorfinn Rowle on Lord Voldemort's orders.

Judging by later remarks made by Vincent Crabbe, it seems that the Malfoys had lost much of their influence in the Death Eater circles. This is due to Voldemort no longer holding Lucius in high esteem and shifting his favour to Draco's maternal aunt Bellatrix Lestrange and Hogwarts teacher Severus Snape.
Draco attended his seventh year of Hogwarts that year. During the Easter holidays, Draco was seen at home in Malfoy Manor. He was called upon by his parents and aunt Bellatrix Lestrange to confirm the identities of Harry, Ron and Hermione, who were caught by a group of Snatchers led by Fenrir Greyback, but Draco showed great hesitation in doing so.
When Hermione lied to Bellatrix under torture about Godric Gryffindor's Sword, Draco was sent to fetch the goblin, Griphook, from the dungeons to get confirmation of the story, which he did by lying saying it was a fake, but the truth was it was the true sword.
Later in the evening, the prisoners managed to escape, and Draco's wand was taken by Harry. Afterwards, Draco and his family were detained to the Manor by Lord Voldemort. Narcissa would lend Draco her wand; it was powerful, yet it didn't understand him, as he had not won its loyalty.
After Voldemort's defeat, Draco and his parents sat in the Great Hall, looking uncertain of their place during the victory celebrations.
