Nymphadora Tonks

Nymphadora "Dora" Tonks is a Metamorphmagus, and an Auror. Her name means "Gift of the Nymphs", similar to "Theodore" ("God's Gift") and "Isidore" ("Isis' Gift"). She despises her given name and prefers to be called by her surname alone.

She is described as having "a pale heart-shaped face, dark twinkling eyes", and is usually depicted with different hair colours, which she can change at will. Tonks is seen to be notoriously clumsy and unskilled at household spells. Nymphadora is the only daughter of Ted and Andromeda Tonks, the latter being sister to Bellatrix Lestrange and Narcissa Malfoy; Nymphadora is therefore Draco Malfoy's first cousin. Tonks is sorted into Hufflepuff, and graduates from Hogwarts one year before Harry enters, after which she begins three years of Auror training; she qualifies as an Auror one year before her first appearance in Order of the Phoenix.

Tonks and Kingsley act as spies for the Order in the Ministry. She helps to escort Harry first from the Dursleys' house to Order headquarters, and later to the Hogwarts Express. Tonks later fights the Death Eaters at the Department of Mysteries, in which she is injured by Bellatrix, and has to be taken to St Mungo's. During Half-Blood Prince, Tonks is stationed at Hogsmeade and assigned to guard Hogwarts. Harry observes she is constantly depressed and rarely smiles. After Dumbledore's death, it is revealed that Tonks has fallen in love with Lupin, and her Patronus has, because of this, changed to the form of a werewolf. Lupin is reluctant to return her affections arguing that he is "too old, too poor, and too dangerous" for her. Because of this, she falls into a depression that disturbs her magical abilities.

However, early in Deathly Hallows, Tonks announces that she has recently married Lupin. Tonks accompanies twelve Order members to take Harry from the Dursleys' home to The Burrow. She flies with Ron, who impersonates Harry using Polyjuice Potion to throw the Death Eaters off the real Harry's trail. During the aerial battle, Tonks fights Bellatrix once again, and injures her husband, Rodolphus. Later in the book, Remus reveals Tonks is pregnant. He leaves her for a brief period, believing that he, through their marriage, has caused her to become an outcast and their unborn child would be better off without him, but changes his mind and returns to her side after a heated argument with Harry. In April of the seventh book, Tonks gives birth to Teddy Remus Lupin, named after her father and husband. Towards the end of the book, Tonks and Lupin join the Battle of Hogwarts. During the battle, Tonks is killed by Bellatrix, and Lupin is killed by Antonin Dolohov, leaving Teddy an orphan to be raised by his maternal grandmother, Andromeda. In an interview shortly after the release of Deathly Hallows, Rowling confessed that she had originally intended for Tonks and Lupin to survive the series ending, but felt that she had to kill them after she spared Arthur Weasley in Order of the Phoenix.
