He was eventually forced to accept that his father was the Muggle parent, and that his mother was the magical one. It was around this time that Riddle gave himself the alias "Lord Voldemort", to spare himself of the reminder of his "filthy Muggle father".
As Tom Riddle discovered his muggle inheritance, his hatred towards both his family and magical society increased, leading him to the path of evil and to adopt the moniker Lord Voldemort.
Tom's eyes became permanently bloodshot and his skin grew paler with every murder he committed and with every horcrux he used. By the time he obtained six horcruxes, he was no longer recognizable as Tom Riddle, rather, he had become the Dark Lord Voldemort entirely, through and through.
In Harry Potter and the Chamber of Secrets, it's revealed to Harry that "I Am Lord Voldemort" is an anagram for Tom Marvolo Riddle. Essentially, Tom appeared to be so disgraced by his family name it seemed easier to create something entirely new and establish a legacy he could be proud of.
The prevailing theory has been that Voldemort gradually lost his nose (and humanity) throughout his life due to his exclusive use of Dark Magic. The more Dark Magic he tapped into, the less human he became both figuratively and literally. This was only amplified as he split his soul to create the Horcruxes.
The Story of Lord Voldemort: Tom Riddle Origins Explained (Re-Upload July, 2017)
How did Voldemort and Bellatrix have a child?
Delphini was born in secret at Malfoy Manor in early March 1998 as the result of a liaison between Bellatrix Lestrange and Lord Voldemort. On 2 May 1998, both of her biological parents were killed in the Battle of Hogwarts.
Harry proceeds to tell Delphi that she will always be an orphan and they return to the correct time, where Delphi would be taken to Azkaban. After Voldemort's death in 1998, Delphi became Salazar Slytherin's last known heir.
Cecilia. Cecilia was a Muggle who was heavily implied to have been Tom's sweetheart. Tom used terms of affection to her and comforted her when she was shocked by Morfin's dead snake. It can be presumed Tom lost her when Merope Gaunt forced him to marry her.
Hagrid and Riddle knew each other since they studied together at Hogwarts. It's, however, never made clear whether Hagrid knew that Voldemort and Riddle were the same person.
Severus Snape eventually joined the ranks of Lord Voldemort's Death Eaters. His actions as a Death Eater are largely unknown, though he quickly became an important Death Eater in Voldemort's inner circle. He was the spy responsible for informing Voldemort about the prophecy foretelling his downfall.
Notably, Voldemort appeared to be entirely unaware of this split, as he later created a seventh Horcrux in his quest to have six, and continued to target Harry Potter despite him now holding part of Voldemort's own soul.
For the second time in Voldemort's life, the unforgivable curse rebounded on him, as the Elder Wand wouldn't kill its master. Since Harry and his friends had already destroyed all of Voldemort's Horcruxes, this finally ended Lord Voldemort's life, with Harry finally defeating the Dark Lord.
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").
By Harry Potter and the Deathly Hallows, it's a stretch to call Draco a villain anymore. We just watched — or read — him struggle to reconcile his choices and morals in The Half-Blood Prince. He can no longer justify his actions, and is far more aware of the evil he was born and raised into.
He is closely associated with the Order of the Phoenix, and has explicitly denied the anti-Muggle/Muggle-born ideology of the Death Eaters. There is quite literally NO plausible way Hagrid could be or ever have been a Death Eater.
She was killed in 1943 by the Serpent of Slytherin, which had been released by Tom Riddle. After the incident, she became a ghost who haunted the second-floor girls' bathroom (and occasionally other bathroom facilities) at Hogwarts.
After Dumbledore's death at the hands of Severus Snape and the Death Eaters' escape from Azkaban in 1997, the Malfoys had fallen out of favour with the Dark Lord. They were extremely uncomfortable with having their home used as his base of operations.
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.
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.
Mason Riddle is the Son of Tom Marvalo Riddle, otherwise known as Lord Voldemort, and the only American student at Hogwarts School of Witchcraft and Wizardry.
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.
She was raised by Euphemia Rowle then Rodolphus Lestrange. It would not be very surprising if they told her everything about Voldemort, his greatness, his power, his ambitions… since he was their master.
