Bellatrix Lestrange
Bellatrix Lestrange (née Black) is a fictional character in the Harry Potter book series written by J. K. Rowling. She evolved from an unnamed peripheral character in Harry Potter and the Goblet of Fire into a major antagonist in subsequent novels. In the final installment of the story, Rowling established her as Lord Voldemort's "last, best lieutenant". Bellatrix was the first female Death Eater introduced in the books. Bellatrix had a fanatic obsession with the Dark Lord although she was clearly fearful of his magical abilities and absolute power over his forces. She is almost as sadistic and homicidal as Lord Voldemort, with a psychotic personality.
