Kreacher was a male house-elf who served the House of Black with fanatical loyalty for most of his life, until he was left to Harry Potter upon the death of Sirius Black in 1996.
He was particularly fond of "his mistress" Walburga Black, who died in 1985, but he still took "mad orders" from her portrait which shrieked from the wall in the front hall of the Black house. After Mrs Black's death, Kreacher let the home fall into disarray, doing little, if any, cleaning.[3]
He was also fiercely loyal to Regulus Black, and later to Harry Potter whom he fought for in the Battle of Hogwarts alongside many other house-elves. Kreacher survived the final battle of the Second Wizarding War; it is unknown what happened to him later in life, though he died at some point after Albus Potter went to Hogwarts.
Personality and traits
Kreacher was very loyal to all the members of the Black family except Sirius Black, whom he hated because he treated Kreacher poorly. He had a strong bond with Sirius' brother, Regulus Black and was devastated by his death. Kreacher was usually hostile, bitter and miserable and had a habit of insulting people, including his masters. He frequently called Hermione Granger a Mudblood. He loathed taking orders from those he hated, often giving them a dirty look or a biting remark.
Like most members of the Black family, Kreacher believed that Muggle-borns and blood traitors were scum. Because of this, he frequently insulted Hermione even though she tried to be nice to him. However, he gradually grew more respectful towards both Muggle-borns and blood traitors, as is seen by his giving Hermione a respectful salute prior to the infiltration of the Ministry of Magic. Kreacher was also very loyal to people who treated him with kindness and respect, particularly Regulus Black. He later grew loyal to Harry Potter and started to be friendly towards Harry, Ron and Hermione. However, he was disloyal to those who treated him poorly. This ultimately led to him being partially responsible for the death of Sirius Black. Had Sirius treated Kreacher the same way his brother had, his death could have been avoided.
While he assisted Regulus in trying to bring Voldemort down, this did not stop him from assisting the Dark Lord through Bellatrix and the Malfoys some fifteen years later. Despite this, he likely did not see a connection between the two events and merely saw both actions as service to the Black family. He also didn't seem to hold any resentment towards Voldemort for trying to kill him and showed no hesitation in helping him indirectly by luring Sirius out of hiding. This is presumably due to the way house-elves are generally treated which, as Hermione says, is not much better than what Voldemort did to him.
Because of years of solitude, Kreacher hadn't cleaned the Black family home for a long time and when the Order of the Phoenix used it as a headquarters, he was rarely seen cleaning. He also had a habit of stealing items that reminded him of his loyalty to the Black family. Kreacher was also considered to be slightly mad, probably from being stuck in the Blacks' house alone for so long. His misery and insanity was most probably a combination of drinking the Drink of Despair, Regulus Black's death, not being able to complete his master's order of destroying the locket, living alone with the locket as well as Walburga's portrait, and Sirius Black's cruelty to him.
A tradition for the House of Black house-elves was for their heads to be cut off and stuck on a plaque. Kreacher and Ron both expressed the wish for this to be done to Kreacher. Ron later regretted this statement.
Eventually, after being given back the locket that Regulus had switched for Voldemort's real Horcrux, Kreacher grew less hostile and was happier than he had been in many years, resuming most of his expected duties. He also led the house elves into the fray during the Battle of Hogwarts.
Magical abilities and skills
House-elf magic: Being a house-elf, Kreacher would have possessed his own very powerful form of magic, which he would have been able to perform both non-verbally and without a wand, as can all house elves. This magic would have likely been very for his house-keeping duties serving the House of Black and as an Hogwarts kitchens employee. For example, he was very capable of levitating objects.[10]
Apparition: Like all house elves, Kreacher was able to apparate even in areas that forbade apparition such as the cave which contained one of Voldemort's Horcruxes, and on the grounds of Hogwarts itself. He was also able to perform Side-Along Apparition (Apparition with another person in tow).
Longevity: Kreacher lived for over six centuries, a tremendous feat for a house-elf, or by the standards of most species. Perhaps had he been given better conditions during his lifetime (it can be presumed the Blacks, although treating him decently, did not give him the best care possible, having a tradition of executing house elves that grew too old) he could have surpassed 7 centuries.[8]
Relationships
Kreacher was extremely devoted to all members of the Black family except Sirius Black, whom he hated. He especially held Walburga Black in high regard and spoke to her portrait with devoted affection. Kreacher often attempted to calm her portrait down when it flew into a rage and referred to it as his mistress even though it wasn't truly Walburga (who had long since perished). Sirius claimed that he was slightly less devoted to Sirius' father than he was to Walburga, though this did not stop Kreacher from trying to save Orion's old ring and a pair of his trousers. It's likely that he held the other members of the family with similar affection and devotion. Considering Kreacher was disloyal to people who treated him in a horrible manner, the Black family must have treated him with some form of acceptable kindness, or at least been successful in brainwashing him into servitude. One family member who is confirmed to have treated Kreacher well, is Regulus.
