* Hermione Granger: During the Battle of the Department of Mysteries, Bellatrix tortured Hermione with the Cruciatus Curse, leaving her traumatized and with a broken nose.
* Neville Longbottom: Bellatrix tortured Neville's parents, Frank and Alice Longbottom, into insanity using the Cruciatus Curse, leading to their lifelong confinement in St. Mungo's Hospital for Magical Maladies and Injuries. This event significantly shaped Neville's life and his journey to becoming a brave and courageous wizard.
* The Longbottoms (Again): Bellatrix was present during the torture of the Longbottoms, though not the main perpetrator. This event, even as a witness, shows her cruelty and sadistic nature.
It's important to note that while Bellatrix tortured many others, these three cases stand out for their impact on the characters and the overall story.
