In the film adaptation, Bellatrix casts the Killing Curse on Sirius instead of this unidentified spell. This spell may have been the Impediment Jinx.
Cruciatus Curse ('Crucio')
Repeated use of the Cruciatus Curse is torture and Bellatrix Lestrange subjected the Longbottoms to such extremes of pain that it sent them insane.
Avada Kedavra (the Killing Curse) was not vividly identified as the spell that hit Sirius Black. According to the circumstances mentioned in the book, Bellatrix Lestrange most likely used a stunning spell against Sirius.
She was remorseless and was cackling in glee after she had murdered Sirius. Bellatrix couldn't stop raving about it and showed it by singing “I killed Sirius Black” multiple times.
Albus Dumbledore arrives and stops most of the fighting, but Bellatrix and Sirius continue. She casts a powerful curse, blasting him in the chest and sending him through the veiled arch.
5 Bellatrix Lestrange: The Cruciatus Curse.
If you've read Harry Potter and the Order of the Phoenix or seen the movie, you already know that it was Bellatrix Lestrange who defeated Sirius Black.
In Deathly Hallows, Hermione faced a real test of her physical and psychological stamina. After being on the run from a bunch of Snatchers, the gang were taken to Malfoy Manor, where Bellatrix proceeded to torture Hermione using the Cruciatus Curse.
Draco's refusal to reveal Harry's identity to Bellatrix was not because he liked him. It was because he believed that Harry was the only chance they had at defeating Voldemort. At first, Draco admired and revered Voldemort until he threatened his family's safety.
The answer is that Sirius wanted to deflect attention from the real Secret-Keeper. He probably hoped Voldemort would go after him so he could steer attention away from Pettigrew.
The darkest of the Dark Arts, Harry Potter unforgivable curses are the Cruciatus Curse, the Imperius Curse, and the Killing Curse. Although the curses are highly illegal, Harry using Unforgivable Curses happened, but he uses them once he was thrust into the Second Wizarding War.
History Of Avada Kedavra
The Killing Curse was created in the early Middle Ages by Dark witches and wizards. Primarily, the curse was used to quickly slay opponents during a duel.
The three Unforgivable Curses in Harry Potter are Crucio, Imperio, and Avada Kedavra, and all three are available to Hogwarts Legacy players. Crucio subjects the victim to extreme torture, while Imperio puts them under the control of the spellcaster.
We know that they did not use Avada Kedavra.
Though Harry encountered many opportunities that deemed Avada Kedavra necessary, it remains as one of the Unforgivable Curses Harry Potter never cast. For one, he viewed the spell as an immoral practice commonly used by users of the Dark Arts.
Harry Potter and the Deathly Hallows
In this book, Rowling reveals that Bellatrix is the guardian of Helga Hufflepuff's cup (though she is unaware that it is a Horcrux), which Voldemort has entrusted the Lestranges to keep in their Gringotts vault.
Narcissa Malfoy's Very Dangerous Lie
But she was also a mother, which meant she was willing to risk everything to make sure her son was safe. When Harry survived Voldemort's Killing Curse for the second time, Narcissa pretended he was dead so she could get to Draco.
Narcissa's greatest moment, however, was when she chose to betray Voldemort in Harry Potter and the Deathly Hallows. Not knowing whether Draco was alive or dead, Narcissa chose to lie to the Dark Lord rather than risk losing her son.
The Cruciatus curse is named by Neville, who has reason to remember it as his parents suffered greatly under it. And the third, the Killing Curse, is named by Hermione; Moody mentions that it can't be blocked, and only one person is known to have ever survived it: Harry Potter.
For example, despite being furious with Bellatrix Lestrange for her murder of his godfather in 1996, Harry Potter was only able to cause her a brief moment of pain with the Cruciatus Curse because he used it out of "righteous anger", though he was still able to knock her off of her feet with it.
In the film Harry Potter and the Deathly Hallows: Part 2, this duel has some noticeable differences: In the film, Bellatrix casts a blue spell at Ginny Weasley instead of a Killing Curse, who deflects it using a Shield Charm.
Winner: Snape
Bellatrix would be in the top pile of witches and wizards of all-time based on powers, but her reliance on the same moves and lack of wit means she would be defeated by Snape after giving him an initially tricky time.
Bellatrix is (kind of) in her prime, while McGonagall is old. We should also know that although Bellatrix is evil, it doesn't mean she's stupid. But seeing that McGonagall is old, we can correctly assume that she's experienced. I'd say McGonagall wins the duel, no questions asked.
He did not love anyone, and did not care to be loved. He felt nothing for his family, and only wanted his friends in school to rally around him because he wanted to hold power over them. Bellatrix Lestrange was obviously in love with him and worshiped him, but he only cared for her servitude, not her.
