Bellatrix Lestrange

Bellatrix was a criminally insane witch with intensely sadistic and brutally violent tendencies. She possessed a fierce and dangerous temper, a trait that she shared with her cousin Sirius and her aunt Walburga and which was likely a result of the inbreeding that plagued her birth family. Bellatrix was one of Voldemort's cruellest Death Eaters, always eager to inflict the Cruciatus Curse on enemies. Harry Potter noted that she was as "mad as her master." Likely for these reasons, Bellatrix was slavishly devoted to Lord Voldemort and was willing to do anything for his cause. She believed to have proven her loyalty by her time in Azkaban, an event which had seemingly furthered her mental decline. Despite her loyalty towards her master, she was able to disagree with him on occasion. She did not trust Severus Snape and believed that Voldemort was mistaken in doing so, though she showed shame and fear when expressing this. Overall, Bellatrix was obsessed with blood purity and took immense pride in the aristocracy of her family since a young age. Like all the rest of Lord Voldemort's followers, she was vehemently against all half-bloods, Muggle-borns, Muggles, and half-breeds. She had a particular disdain for blood traitors, having no qualms towards killing members of her own family, including her cousin Sirius and her niece Nymphadora, whom she sought to kill with great determination. Given her reaction to Harry's words that Voldemort is a half-blood, it is likely that she didn't know that her master wasn't a pure-blood or at least was in denial. Bellatrix was intelligent and a natural leader, taking charge in tricky situations. These traits were shown during the Battle of the Department of Mysteries and the Skirmish at Malfoy Manor. The latter event was a mark of her decisiveness and ruthlessness, as she took no unnecessary prisoners (preferring to kill them instead) as she planned to do with a group of Snatchers who attempted to defy her. However, Bellatrix could be easily distracted and reckless, especially in battle with opponents that appeared to be (or were) weaker than herself. Bellatrix was also egotistical and arrogant, described by Harry as "treat[ing] everyone like scum" in a rather taunting way. She had immense confidence in her skills and never hesitated to jump into battle against any auror or Order of the Phoenix member. Furthermore, she was immensely proud of her status as the most loyal and devoted follower of Lord Voldemort. However, Bellatrix chose to flee when Dumbledore arrived, suggesting that, like her master, she held a degree of fear and caution for the powerful wizard. Despite her cruel personality, Bellatrix was not incapable of caring for a few people. She was obsessively in love with her master, Lord Voldemort. She had a close relationship with her younger sister Narcissa Malfoy, grudgingly going with her to Snape's house to ask his help, and didn't tell her master of her sister's deception. She also showed affection for her nephew and student Draco Malfoy but didn't seem to be too concerned about his safety, as she would "be glad to give [her own sons] up to the service of the Dark Lord".

Appearance: Bellatrix had the classic "great good looks" and arrogant bearing common for members of the House of Black. She was a tall woman with long, thick, shiny dark hair. Her face had a strong jaw, a thin mouth, and dark, heavily lidded eyes with long eyelashes. As a Death Eater, Bellatrix bore the Dark Mark on her left inner forearm. However, (like her cousin Sirius Black) her lengthy imprisonment in Azkaban took a toll on her appearance. Her face became gaunt and skeletal, but she still managed to retain vestiges of her great beauty. Bellatrix Lestrange is a striking and menacing figure, her appearance as dark and wild as her temperament. She has long, thick, and curly black hair that tumbles in an untamed mass around her pale, gaunt face, often giving her a feral or witch-like look. Her skin is pallid, almost corpse-like, enhancing the intensity of her features. Her eyes are heavily lidded and dark, with a wild gleam of madness dancing in them—a look of both cunning and cruelty. There's often a manic energy in her expression, a mix of aristocratic arrogance and unhinged delight in chaos. Her smile is unsettling, often twisted into a sneer or grin that suggests she's enjoying someone else's pain. Bellatrix has a slender, tall figure, but her movements are unpredictable—sometimes graceful in a deadly, serpentine way, other times jerky and volatile, mirroring her unstable mind. In terms of attire, she typically wears long black robes, tight-fitting and gothic in style, often tattered or adorned with corset-like elements. The overall effect is sinister and elegant, echoing her pure-blood elitism and Death Eater allegiance.
