However, when Bill Weasley was attacked by
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.
In 1997, he suffered severe facial wounds at the hands of the vicious werewolf Fenrir Greyback during the Battle of the Astronomy Tower. Although untransformed at the time, Greyback's lycanthropy caused the wounds to be cursed. The scars could not be treated totally, leaving Bill heavily scarred.
During the fight, Fenrir Greyback (a malicious werewolf) bites Bill and mangles his face, ensuring that he will never look the same again.
At some point in his early life Fenrir was bitten by a werewolf and infected with lycanthropy. Throughout most of his life, his only goal in life was to infect as many people as possible, in order to create enough werewolves to defeat the wizarding world.
Harry Potter: Why Remus Lupin and Fenrir Greyback Look So Different As Werewolves. Unlike Fenrir Greyback, Remus Lupin never embraced his lycanthropy, and this shows in his hairless, emaciated wolf form in Harry Potter.
Remus was only four when he was bitten, and spent a difficult childhood coming to terms with what had happened. Even worse, Greyback only targeted Remus because his father, Lyall, had insulted werewolves.
Really, it was Percy's youth and inexperience in the world, as well as his need to escape what he perceived as the limitations of his family, that caused him to take the wrong path. But everyone makes mistakes, especially when they're young, and Percy redeemed himself in the end.
He was bitten by the vicious werewolf Fenrir Greyback when he was a small child, and became infected with lycanthropy; the condition being incurable, he was doomed to live his life as a werewolf.
He took a brutal werewolf attack in his stride like an absolute champ. When Bill was mauled by Fenrir Greyback, he was scarred for life. This would be enough trauma to drastically alter even the strongest of people.
Fenrir Greyback is, perhaps, the most savage werewolf alive today. He considers it as his mission to bite and to contaminate as many people as possible; he wants to create enough werewolves to overcome the wizards. Voldemort has promised him prey in return for his services.
This may have been because Lord Voldemort was prejudiced against werewolves as well as Muggles and Muggle-borns. Therefore he would not allow Greyback to become an actual Death Eater, yet he was too valuable of an accomplice not to have in his ranks.
He rose as a mighty acolyte in Grindelwald's inner circle and married to French witch Vinda Rosier. After the Dark Wizard's fall from grace and defeat at the hands of Albus Dumbledore, Fenrir supported Tom Riddle - now "Lord Voldemort" - in his ascension.
The monthly transformation of a werewolf is extremely painful if untreated and is usually preceded and succeeded by a few days of pallor and ill health. While in his or her wolfish form, the werewolf loses entirely its human sense of right or wrong.
The eldest of the Weasley children, Bill was both a prefect and a Head Boy and of course a Gryffindor. By the time his youngest brother, Ron had arrived at Hogwarts with Harry Potter, Bill was working for Gringotts bank in Egypt as a curse-breaker.
Dark Arts: Bill was surprisingly skilled with dark magic, as he successfully invented his own curse, a potent dark charm of the highest severity. His modified cursed barrier was powerful enough to prevent Death Eaters from penetrating it, which is very impressive dark magic.
Snape hears Lupin admit this while hiding under the Invisibility Cloak and also hears Lupin explain that he was not part of Sirius's joke. Snape still thinks Lupin is helping Sirius, however, and attacks Lupin. He then lets slip that Lupin is a werewolf the next morning.
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.
Harry, returning to the school, looks into the Great Hall and sees Lupin and Tonks lying among the dead. While this is not mentioned in the book, the author has mentioned in an interview since its publication that Tonks was killed by her aunt Bellatrix Lestrange.
Some pure-bloods were considered “blood traitors” for not only being unbiased about blood purity and towards Muggles, but for showing outright fondness and admiration for the Muggle world. The Weasleys are known for not supporting the notion of blood purity and for associating with Muggles and Muggle-borns.
In a tense moment, Percy apologised profusely to his family, and his brother Fred, who, along with George, were the most vocal in their anger towards Percy, was the first to forgive him. Reunited with his family, he stood alongside with the defenders of Hogwarts against the Death Eaters.
You are sorted into a house based on what you value, not the traits you posses. Percy valued the Gryffindor traits and therefore was sorted into Gryffindor.
During the Battle, Lavender was attacked by Fenrir Greyback but was saved by Harry and Hermione. Although she was scratched on the neck, much like Bill Weasley, she only developed wolfish tendencies and didn't turn into a full werewolf.
It states that Draco was bitten by Fenrir Greyback after Harry Potter and the Order of the Phoenix takes place because of Lucius' mistakes.
In her final year of schooling Lavender joined the reconstituted D.A. to oppose Death Eater control of Hogwarts and fought in the Battle of Hogwarts. During the battle she was savaged by werewolf Fenrir Greyback and died of her injuries.
