Harry Potter: "You know Voldemort's snake, Neville? He's got a huge snake... Calls it Nagini... It's got to be killed.
Ron and Hermione know that, but just in case they — Just in case they're — busy — and you get the chance —"
Neville Longbottom: "Kill the snake?"
Harry Potter: "Kill the snake."
— Harry arranges for Neville Longbottom to kill Nagini, Voldemorts final Horcrux.[src]
Nagini (d. 2 May, 1998) was a long, green female snake belonging to Lord Voldemort, with whom she had a special bond.
She also became a Horcrux, after her master killed Bertha Jorkins in 1994. After Voldemort's initial downfall, he used
Nagini's venom as one of the ingredients for a potion in order to regain strength, which eventually led to his rebirth.
In 1995, she attacked Arthur Weasley, but he managed to survive. During the Second Wizarding War, she had to be
destroyed in order for Voldemort to be finally defeated. Nagini was killed by Neville Longbottom in 1998, and was the
last Horcrux to be destroyed.
Nagini tells me that the old Muggle caretaker is standing just outside the door! Step aside, Wormtail, so I can give our
guest a proper greeting... Avada Kedavra!'"
—Voldemort after Nagini speaks to him in Parseltongue[src
It's unknown when, where or how Lord Voldemort encountered Nagini but she became his magical familiar and the only
living creature, apart from himself, that Voldemort cared about. Since he liked to possess snakes it is possible that
the Dark Lord found Nagini whilst he was in Albania after attempting to kill Harry Potter. He used Nagini to help him
regain strength and a basic physical form after living in a weak, spectral state, following his attempt to kill an
infant Harry Potter, during which he was struck by his own rebounding Killing Curse. He had Peter Pettigrew milk her
venom, and with it, create a potion that sustained him until he could regain a body. Nagini further kept Voldemort alive
after he turned her into a Horcrux, with the murder of Bertha Jorkins, in 1994; his habit of keeping her unusually close
to him was what led Albus Dumbledore to suspect that she had become a Horcrux. Nagini was also able to alert her master
to the fact that Frank Bryce was listening in to a conversation between Peter Pettigrew and himself, leading Voldemort
to kill the Muggle man.
Nagini was frequently used by Voldemort to kill others, or to dispose of their dead bodies. In 1995, he promised Nagini
that she could devour Harry Potter after he had killed him. However, she was denied this when Harry escaped from the
graveyard shortly after the promise was made. It is likely that Frank Bryce met that intended fate, sometime in 1994.
Voldemort threatened Pettigrew with being fed to Nagini if Bartemius Crouch Sr. was able to contact Albus Dumbledore
about the plot behind the Triwizard Tournament.
He also used Nagini in the aforementioned attempt to kill Arthur Weasley. In 1997, Voldemort's prisoner, Hogwarts Muggle
Studies teacher, Charity Burbage, was fed to Nagini. Later, when Thorfinn Rowle and Antonin Dolohov failed to capture
Harry, Voldemort offered them a choice in punishment: being tortured by Draco Malfoy further or be killed and devoured
At Christmas in the same year, Nagini was stationed at Godric's Hollow, posing as Bathilda Bagshot using extremely
powerful Dark Magic. When Harry and Hermione Granger arrived there, she lured them into the late witch's home, signaled
Voldemort, and attacked Harry. Nagini bit and coiled herself around Harry to hold him in place until Hermione came to
his assistance, using a Blasting Curse against the snake; the two escaped just before Voldemort arrived.
Later, on Potterwatch, Lee Jordan revealed that the remains of Bathilda's body had been found after being informed by
the Order of the Phoenix.
In 2011, Nagini was placed in an enchanted barrier by the Dark Lord, who told her it was for her own good, though since
he was trying to ensure his own immortality, it was primarily for his. Later on, while in the Shrieking Shack, she
killed Severus Snape on Voldemort's command, biting his neck and injecting him with her deadly venom. After Voldemort
tried to kill Harry Potter in the Forbidden Forest, she was released from the orb, as Voldemort believed there to be no
more threat of her being killed, and he wore her around his neck and shoulders, like a scarf. She was beheaded by
Neville Longbottom using Godric Gryffindor's Sword during the penultimate confrontation.
Since she was the last remaining Horcrux, her death set up the climactic duel between Voldemort and Harry Potter. With
no Horcruxes remaining and thus being mortal again (thanks to Neville), Voldemort's death in that duel was final.
Nagini was a green viper, roughly twelve feet long and as thick as a man's thigh. As a viper, she was known to be
venomous, and her venom was used to sustain her master prior to his return to true physical form.
Personality and traits
Nagini was completely loyal to Lord Voldemort. While she remained aloof to most others, she obeyed Voldemort completely,
and seemed to enjoy being close to him, as she often slithered up to his shoulders to recieve his affection. Nagini is
also shown to understand the concept of strategies and plans, as seen when she sets up a trap for Harry. She was rather
cunning and deceptive, and seems to have understood how humans behave.
I think he is perhaps as fond of her as he can be of anything. He certainly likes to keep her close and has an unusual
amount of control over her, even for a Parselmouth."
—Albus Dumbledore on Voldemort's bond with Nagini
Voldemort had a special relationship with Nagini, as she was his magical familiar and one of his Horcruxes. According to
Dumbledore, Voldemort had strong feelings for Nagini that he had not for anyone else; she was the one thing that he
cared about. He was able to communicate with Nagini as a Parselmouth, and he turned her into a Horcrux in 1994, after
murdering Bertha Jorkins, which accounted for the unusual amount of control he had over her. By 1997, and likely before
then, he was able to communicate with her silently and across great distances, as she was able to signal to him when
Harry Potter arrived at Godric's Hollow. This may have been due to her nature as a Horcrux, giving her a link to
Voldemort like the one Harry possessed.
Voldemort was also able to possess Nagini, which he did in December 1995. When he possessed her, she entered the
Ministry of Magic, and attacked Arthur Weasley, who was on watch duty (guarding Harry's prophecy) for the Order of the
Phoenix in the Department of Mysteries. Arthur survived the attack as a result of Harry dreaming about and being
connected with Voldemort/Nagini at the time: Harry was able to warn Professor McGonagall, and subsequently Dumbledore,
who managed to find Arthur before his injuries proved fatal. It took quite a while for Arthur to recover in St Mungo's
Hospital for Magical Maladies and Injuries due to the fact that Nagini's venom seemed to delay blood clotting, and even
dissolved stitches, causing the wounds to bleed profusely when the bandages were removed.
In 1994, Peter Pettigrew milked Nagini's venom to return Voldemort to a rudimentary body, and as a Horcrux, her very
existence contributed to maintaining Voldemort's immortality. Voldemort usually sent her on missions, such as
infiltrating the Ministry, or holding Harry Potter in Godric's Hollow. He allowed her to consume the corpses of those he
killed as a reward, though this also served as a way for him to dispose of bodies.
He stopped sending Nagini on missions after he realised Harry Potter knew about the existence of his Horcruxes and was
tracking them down. Eventually, Nagini was beheaded by Neville Longbottom during the Battle of Hogwarts. Voldemort was
furious, and attempted to kill Neville. Nagini was the last destroyed Horcrux, and her death led to Voldemort's final
