Her real parents were Daneel and Dean Novak, Pureblooded wizards. Turns out Daneel was Tom Riddles younger sister, Daneel Riddle. Of course, the Riddles were related to Salzar Slytherin himself, and this made Hermione the living heir of Slytherin.
In the Chamber itself, we see a large statue of a wizard, which Harry presumes is Salazar Slytherin. We also meet Tom Riddle, who is, as it turns out, the heir of Slytherin. Present only in spirit, he has all the same been controlling Ginny, and having her act as Slytherin's heir.
In the books and on Pottermore, Hermione Granger was Sorted into Gryffindor. We also see Hermione mention that the Hat had difficulty deciding whether to put her into Gryffindor or Ravenclaw, and ultimately decided to put her in Gryffindor.
The Heir of Slytherin turns out to be Ginny Weasley, who is being controlled via a magical diary that once belonged to Tom Riddle, AKA Voldemort.
Harry was never the true Heir of Slytherin through his family line. He was able to speak to snakes due to having part of Voldemort's soul embedded in his lightning-shaped scar (CS18, DH33). The "Heir" was the soul-bit of Tom Riddle left behind in the Horcrux diary.
Andrea Deanisi as Wiglaf Sigurdsson, the Heir of Rowena Ravenclaw.
Harry is the Heir of Gryffindor (though his powers have been bound by his father when he was a baby), Neville is the Heir of Hufflepuff, Meghan (OFC, daughter of Sirius) is the Heir of Ravenclaw.
Through this dialogue, Tom grew stronger and ultimately poured a little of his soul into Ginny, manipulating her to kill Hagrid's roosters and open the Chamber of Secrets.
Ginevra Molly Weasley (also known as Ginny) is the youngest child and only daughter of the Weasley family. She is Sorted into Slytherin during Harry and Jim Potter's second year.
Myrtle's life was cut shockingly short when she was killed by the Basilisk at Tom Riddle's command.
And this is why Hermione does not fit into Ravenclaw, since she lacks their creativity of thought. When you also add in her fearlessness and her strong convictions about right and wrong, which are inherently Gryffindor traits, then there was even less of a chance she'd end up wearing blue and bronze.
He is cunning
Slytherins are a cunning lot, and there are all kinds of examples of Albus Potter using his wiles to come up with schemes and plans worthy of any member of Salazar's house throughout Harry Potter and the Cursed Child.
Ron Weasley
Being Harry Potter's best friend certainly needed heaps of bravery – hence the Sorting Hat not messing around in sorting Ron into Gryffindor, the house of his parents, brothers and sister. But the Hat specifically states that Gryffindors usually have 'daring, nerve and chivalry'.
The Heir of Hufflepuff was a person foretold by the Seer Harmonthrep (Ajrand) to bring great glory and honor to the House of Hufflepuff, considered boring and lackluster by most.
Slytherin disliked taking students from Muggle families, seeing them as untrustworthy and unworthy of being taught magic, and tried to persuade the other founders to only take students from pure-blood families. However, the other founders didn't agree with Slytherin, particularly Godric Gryffindor.
Severus Snape, Horace Slughorn, Andromeda Tonks, Narcissa Malfoy and Regulus Black were all Slytherin heroes in their own way, if you think about it. And Merlin – as in, yes, King Arthur's advisor and the most famous wizard in history – was a Slytherin.
Hermione Malfoy (née Granger) is the daughter of Mr Granger and Mrs Granger, wife of Draco Malfoy, Daughter-in-law of Lucius Malfoy and Narcissa Malfoy (née Black), Mother of Hyperion, Hyperion II, Scorpius, sister-in-law of Miss Malfoy and friend of Harry Potter.
Ginny Weasley was able to speak Parseltongue while she was possessed by Tom Riddle's Diary, which enabled her to open the Chamber of Secrets.
In addition, Lucius Malfoy and Arthur Weasley have a well-established feud despite being second cousins once removed by marriage.
However, Tom was in love with a Muggle woman named Cecilia and did not noticing Merope or her affections towards him. Determined to have Tom for herself, Merope was said to have given Tom a love potion to make him fall in love with her.
Cecilia was a young, pretty Muggle woman who seemed to have been romantically involved with Tom Riddle Senior prior to his marriage to Merope Gaunt.
It is revealed during the series that Hagrid attended Hogwarts while Tom Riddle was also a student at the school, and that Hagrid was expelled during his third year (because Riddle, in his pre-Lord Voldemort days, framed him for opening the Chamber of Secrets).
Peter Pettigrew represents the worst Gryffindor in the entire Harry Potter series. Wormtail, as he was known among his friends, was thought to be a friend of the Marauders and a member of the Order of the Phoenix, but he was secretly working for Voldemort and committed the ultimate act of betrayal in the series.
The lightning bolt scar that was so vibrant in the first films has almost completely disappeared. The scar is no longer dark, and instead has faded almost to his usual skintone. Scars do fade with time, but J.K Rowling wrote in the book that: "The scar had not pained Harry for nineteen years. All was well."
Their names were Godric Gryffindor, Rowena Ravenclaw, Helga Hufflepuff and Salazar Slytherin.
