Roughly translated, Expelliarmus – the Disarming Charm – means 'to drive out a weapon' and that's what it does: forces the subject to drop whatever they're holding. Usually that's a wand, which is why it's often seen in duels, and Harry definitely took that to heart, given how much he used it in combat.
Harry's signature spell is red, possibly representing gryfindor and everything good.
So, the moment Harry cast Expelliarmus, it collided with Voldemort's own Killing Curse, the spells connected, Elder Wand finally realized and recognized Harry as its true master, and made the curse rebound. The Killing Curse rebounded on Voldemort, hence finally killing him.
Why does expelliarmus cause snape to fly into the bed in Prisoner of Azkaban film? expelliarmus is used to disarm an opponent. It's used over and over to cause the wand to fly out if peoples hands.
The Expelliarmus spell is the Disarming spell; it knocks the victim's weapon (usually a wand) out of his/her hands. It can also be used to knock other items out of the target's hands, but we seldom see this use.
Malfoy spots Harry and casts a Cruciatus curse; Harry, defending himself, using the Half-Blood Prince's Sectumsempra spell without knowing its effects. To his horror, it gashes Draco's face and chest, spilling his blood everywhere. Moaning Myrtle flies off, screaming.
Cruciatus Curse ('Crucio')
Harry tried to use this spell himself. The first time was against Bellatrix after she had killed Sirius. His attempt was unsuccessful because, as Bellatrix mockingly explained: 'You need to really want to cause pain – to enjoy it – righteous anger won't hurt me for long…'
Harry became so enamoured with the spell that he eventually used it to finish off Lord Voldemort. Here's how Harry's relationship with Expelliarmus became his signature – and why that's a good and bad thing.
Throughout the entirety of the franchise, Harry is thrown into the most heat, and his skills as a wizard are constantly tested. That being said, his go-to spell has to be Expelliarmus.
Avada Kedavra
Topping the list for the most powerful spells in the Harry Potter universe is no other than Avada Kedavra, Voldemort's favorite to instill his will and fear onto others. The spell itself is a play on Abra Kadabra and is easy to cast by just about anyone in the Wizarding World.
To do this, they must first commit murder. Voldemort intentionally made six Horcruxes, but when he used Avada Kedavra on Harry, he unintentionally created a seventh Horcrux. Instead of dying, Lily's love for Harry created a counter 'curse' known as Sacrificial Protection and saved Harry.
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.
She stared Bellatrix down and challenged her to a one-on-one duel. Molly Weasley had hit Bellatrix Lestrange straight in the heart with an unspecified spell and killed her on the spot. Since Avada Kedavra is an unforgivable curse, many fans have argued that it is not what Molly used.
It was Snape who taught Harry his signature spell: Expelliarmus.
Green is the colour of much 'Dark' magic; of the 'Dark Mark', of the luminescent potion in which Voldemort conceals one of his Horcruxes, of many 'Dark' spells and curses, and of Slytherin house.
As the youngest Weasley, we're sure Ginny observed more than her fair share of unpleasant spells over the years but it was the Bat Bogey Hex she was famous for – and with good reason.
The spell that Hermione uses most is either Alohamora or Reparo.
Firestorm. Firestorm was a spell that created a large ring of fire around the caster's wand. This spell is one of the last and most powerful spells that Albus Dumbledore cast using the elder wand before his death.
He is also revealed to be a double agent for Albus Dumbledore and the Order of the Phoenix. But many people forget that he also invented a number of spells. In the Harry Potter movies, Snape came up with the Sectumsempra curse when he was a student at Hogwarts, and it's known to cause painful lacerations on the target.
In Harry Potter And The Deathly Hallows Part 2, Voldemort kills Snape using his snake Nagini instead of his favorite spell Avada Kedavra - here's why. Voldemort killed Snape in Harry Potter And The Deathly Hallows Part 2 using his Horcrux snake Nagini instead of his favorite Unforgivable Curse, Avada Kedavra.
In Harry's case, he is consumed with a righteous anger rather than a malicious intent. Draco Malfoy attempts to use this curse on Harry at one point, but is forestalled by Harry's use of Sectumsempra.
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.
Avada Kedavra, also known as the Killing Curse, kills a person instantaneously and without injury. There is few counter for it, and only one person, Harry Potter, has ever survived it with Sacrificial Protection that has been endowed upon Harry Potter by His Mother Love for Him.
