After her time at Hogwarts, Bellatrix managed to become a Death Eater for Voldemort, something that would only serve to further her power. It was at this point that she would develop twisted romantic feelings for Voldemort, though the dark wizard was a bit more preoccupied with his own evil schemes.
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.
Bellatrix is an intensely violent, brutal, and cruel Witch who is motivated mainly by her own sadistic love to give suffering. She was fierce and dangerous, a trait which she shared with her cousin Sirius and aunt Walburga and which was probably the result of the inbreeding which prevailed in her biological family.
The Life of Bellatrix Lestrange: Entire Timeline Explained (Harry Potter)
Who got Bellatrix pregnant?
In the play "Harry Potter and the Cursed Child," which has become part of "Harry Potter" canon, it was revealed that Bellatrix conceived a child with none other than Lord Voldemort.
Before her death, Bellatrix secretly gave birth to an illegitimate daughter named Delphini, whom she conceived with her beloved master, Lord Voldemort. Delphini was conceived sometime after the Battle of the Department of Mysteries in 1996 and before the Skirmish at Malfoy Manor in 1998.
Who is Delphini raised by? After the deaths of her parents, Voldemort and Bellatrix Lestrange, Delphini is raised by Euphemia Rowle, who was not fond of her and allegedly only took her because she was offered a substantial amount of gold.
Delphini, nicknamed Delphi, is the titular main antagonist of Harry Potter and the Cursed Child. Although she initially introduces herself as the niece of Amos Diggory, Delphi is in fact, the child of Lord Voldemort and Bellatrix Lestrange and has only one goal, restoring her father.
In Harry Potter and the Cursed Child, it is revealed that Bellatrix gave birth to Voldemort's daughter Delphi in Malfoy Manor before the Battle of Hogwarts.
Bellatrix aiming the killing curse at Ginny proved to be the final straw for a woman who had to endure so much since the return of Voldemort and his followers. It's because of this rage and hatred that the duel erupts with such potency.
Of course Bellatrix wanted to kill Sirius. She's a crazed psychopath who enjoys killing, and Sirius openly defied everything Bellatrix believed was right.
Her disregard for human life and her pleasure in others' pain made her a deadly force. Bellatrix's devotion to Voldemort also means that she would have done anything to please him — no matter the cost. However, what fans most despise her for is the murder of her cousin, the beloved Sirius Black.
Family. Snape's family background is mostly shown in flashbacks during the course of the last three novels. Snape was born to Eileen Prince, a witch, and Tobias Snape, a Muggle, making him a half-blood (hence the name, "Half-Blood Prince").
Lord Voldemort had no wife he and Bellatrix just made a baby together. Voldemort couldn't love anyone. But the girl mother (In cursed child) is Bellatrix Leatrange.
In the Cursed Child, Bellatrix and Voldemort produce a daughter named Delphi. She was supposed to be born a few weeks before the Battle of Hogwarts and was subsequently orphaned when both mother and father were killed.
Delphini Diggory was a mysterious young woman, whose past was filled with mystery. When she first met Albus and Scorpius, she claimed to be Amos Diggory's niece and accompanied the boys as they travelled back in time in an attempt to change the course of time and save Cedric Diggory.
The Delphinus connection explains why Delphini has such a strange hair color, as Alpha Delphini appears to have a blue and white hue when observed in the sky and Delphini has blue and silvery grey hair.
A member of the house of Black, one of the oldest wizarding families, Bellatrix was also Draco Malfoy's aunt. Renowned for her cruelty and sadistic nature, many of the acts of torture and violence against Voldemort's enemies were carried out by Bellatrix Lestrange.
Delphini "Delphi" Diggory is Voldemort's secret daughter (wow, the Potterverse is turning into a soap opera). She wants to resurrect the Dark Lord—not necessarily to bring evil to the world, but just because she wants to meet her dear ol' dad. It's actually kind of sweet…in a completely evil way. Ooh, dang.
In the final movie, Harry Potter and the Deathly Hallows pt. 2, Molly first hits Bella with a spell that freezes her, most likely Petrificus Totalus. Then, she launches another one that shatters her entire body into pieces, which could be expelliarmus, bombarda, stupefy, or any spell that can produce such an effect.
