With close friends Antonin Dolohov, Lucius Malfoy, her sister Narcissa, and Severus Snape, she made the Gryffindor's lives hell, especially those certain prats she hated the most: James Potter, Sirius Black, Remus Lupin, Lily Evans, Katie Jones, Novalee Sollows and Peter Pettigrew.

Being a Pureblood Slytherin female, and a member of one of the wealthiest wizard families, made most scared of Bellatrix, witches and wizards of all blood-lines doing their best to avoid her, especially once she had gotten angry. The only muggle-born whom had ever stood up to Bellatrix was Potter's girlfriend Lily Evans, and she had made her pay for it, almost with her life.

Her heart had been stolen by the gorgeous Antonin Dolohov, also a member of a pureblood wizarding family, he had a great hate for mudbloods also, which Bellatrix respected, and craved for him more. He was in her year at Hogwarts, and a close friend of hers, her sisters and Lucius's, they made up a tight group which also included Severus Snape. However, finding that the only person she had ever loved, Antonin, had betrayed her, she fell in love with Rodolphus Lestrange, going on to marry him and becomming Bellatrix Lestrange. Together with their inner circle of friends, they studied the dark arts, later becomming the most powerful witches and wizards in the wizarding world under their leader Lord Voldemort.
