In the Order of the Phoenix film, Death Eaters and Order members apparate and disapparate in clouds of black and white smoke respectively. In the film, both sides also appear to be able to "half-apparate" in which their bodies were made out of smoke, giving them the recently improvised ability to fly.
Death Eaters are shown physically collapsing into thick black plumes of smoke, shooting off into the sky, and being able to go wherever they want to, while doing this. Even though many people think this is apparition, it is not. It is just an ability that was given to the Death Eaters in the movie series.
Snape was described as 'bat-like' when he was seen flying, with Professor McGonagall observing he must have learnt 'a few tricks' from Lord Voldemort, who presumably was so magically gifted that he invented the spell himself. Whether the secrets of flight died with him, however, no one knows.
He magically bred a thestral with a demiguise, essentially piggyback riding on an invisible ape. Voldemort is actually riding a very small magic carpet that fits under his robe. Voldemort is holding a second wand with his toes and is constantly using a spell that pushes air, giving his billowing cloak updraft.
In the books, the Death Eaters simply Apparate and Disapparate like every other wizard or witch. Popping out of thin air is hardly the most cinematically striking visual. As a result, the Death Eaters are shown flying around like dark smoke.
The Death Eaters and the Dark Lord don't simply cast Avada Kedavra on everyone all the time because it doesn't suit their long-term goal of ruling the world and having a wizard-run society.
The most likely reason why Lord Voldemort's nose disappeared and he devolved into such an evil-looking creature is that as he dabbled deeper into the Dark Arts, his appearance gradually became as distorted as what remained of his twisted soul.
In 2006, Rowling told an interviewer that Voldemort at his core has a human fear: the fear of death. She said: "Voldemort's fear is death, ignominious death. I mean, he regards death itself as ignominious. He thinks that it's a shameful human weakness, as you know.
Voldemort can not comprehend love, and so it destroys him to touch Harry because Lily's love for her son runs through Harry's veins and body. ems Harry burnt Quirrell's face when he touched it.
Voldemort apparently believes nothing is worse than death; perhaps his greatest weakness is his inability to love. This is because his mother, Merope Gaunt, gave Tom Riddle Senior (Voldemort's father) a love potion. Because Voldemort was conceived under a love potion, he isn't able to feel or express love in his life.
It's a word that gained so much more clarity and tragedy after Harry Potter and the Deathly Hallows revealed that the nefarious Professor Severus Snape was actually serving a nobler cause: protecting Harry from Voldemort out of love for Snape's childhood friend Lily Evans.
The Reddit thread agrees Snape's Boggart may revolve around the person who mattered most to him: Lily Potter. Snape's unrequited love for Lily lead to his greatest fear coming true, a fact that wasn't revealed until The Deathly Hallows.
Severus Snape: Doe
In the memories he gives Harry before his death, Snape shows Dumbledore his patronus, using the form to prove his love of Lily Potter, Harry's mother. This indicates that Lily also had a doe patronus.
Bill is viciously mauled by the werewolf, Fenrir Greyback. Fortunately, as Fenrir was not transformed at the time, Bill did not become a werewolf, though Madam Pomfrey is unable to completely heal his face, and he remains permanently scarred.
Even when battling Voldemort, in Harry Potter and the Order of the Phoenix, Dumbledore never uses lethal magic. In the duel, Dumbledore is definitely on par with Voldemort, and Voldemort is seen to be annoyed that he can't overpower Dumbledore.
Discomfort following an event is common with nausea, heartburn, abdominal cramping, and diarrhea. People may also use laxatives or force themselves to vomit following the event, with associated risks.
Quirrell didn't use the Killing Curse on Harry, because Voldemort said “use the boy” to get the Sorcerer's stone from the Mirror of Erised.
Voldemort hugged Draco as an improvisation and it wasn't planned. Even Tom Felton (Draco Malfoy) was caught unaware which increased the effect. In Harry Potter style, it was like a welcome for Draco, but as Voldemort had never known love, he didn't know how to hug him very well. Thats why they had the awkward hug.
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.
Albus Dumbledore
It is not certain what the specific fear is as he is not fearing the death of his sister as she is already deceased and it is suggested that Dumbledore fears that it was him who directly killed his sister in the conflict or that he fears the loss of control that lead to his sister's sudden death.
On Lord Voldemort as a psychopath or sociopath
“There are psychologists who would argue there's really no difference, and in fact, if you consult the diagnostic manual, it would really lump them under one category, antisocial personality disorder.
He is not even afraid of Voldemort, even though everyone else in the world of Harry Potter is scared of him. One possible reason for this is that Dumbledore is smart enough to know that fear is rarely helpful. Being scared because of something or someone only makes someone nervous.
Snape having the same Patronus, the doe, as Lily symbolized his everlasting love and unwavering devotion towards her. He hadn't stopped loving her after their last altercation, marriage to James Potter, or death. She was his "always," his guiding light, and he protected Harry for her.
Harry proceeds to tell Delphi that she will always be an orphan and they return to the correct time, where Delphi would be taken to Azkaban. After Voldemort's death in 1998, Delphi became Salazar Slytherin's last known heir.
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.
