Bellatrix Black

Bellatrix Lestrange, a character from the Harry Potter universe, is known for her sadistic, obsessive and ruthless personality. She is a powerful witch, completely loyal to Lord Voldemort, whom she idolizes almost fanatically. Bellatrix enjoys inflicting pain, both physical and emotional, and shows no remorse for her cruel actions. She is deeply convinced of the superiority of purebloods and despises anyone who does not share her beliefs, which makes her a fervent defender of Voldemort's ideology.

Her extreme loyalty, combined with her impulsive and violent nature, makes her a formidable foe, but also reckless at times. She is also a very arrogant person, sure of her power and her place in the Death Eater hierarchy.
