Morfin Gaunt (around 1900 – 1943) was a pure-blood wizard descended from Salazar Slytherin. He was the son of Marvolo Gaunt, brother of Merope Gaunt, and uncle of Tom Marvolo Riddle, also known as Lord Voldemort. After he hexed Tom Riddle Snr with painful hives, a Muggle who lived near his home in Little Hangleton because his sister was infatuated with him, his recklessness and disregard for wizarding law attracted the attention of Ministry of Magic officials who sent Bob Ogden to the Gaunt Family. After a fight where he and his father assaulted a Ministry investigator, Morfin was imprisoned in Azkaban for three years. When he returned home, his father and sister had already died. In 1943, Morfin met his nephew, who killed his paternal family and then altered Morfin's memory so that he believed he was the murderer and that he was proud of it. Morfin died in Azkaban, but not before Albus Dumbledore learned the truth about the Riddle murders.
Morfin lived with his father and sister in a shack near Little Hangleton. Generations of inbreeding in the House of Gaunt caused a defect in Morfin, rendering him mentally deranged and violent. He almost exclusively spoke in Parseltongue and frequently terrorised Muggles, including Tom Riddle Snr after Morfin noticed his sister watching him with interest. He, like his father, was abusive toward Merope.
- "She likes looking at that Muggle. Always in the garden when he passes, peering through the hedge at him, isn't she? And last night... Hanging out of the window waiting for him to ride home, wasn't she? But I got him, Father! I got him as he went by and he didn't look so pretty with hives all over him, did he, Merope?"

Morfin's violent behaviour eventually led to the Ministry of Magic pressing charges against him; in particular for causing Tom Riddle Snr, a Muggle, to erupt with hives. Bob Ogden, head of the Magical Law Enforcement Patrol, was sent to summon Morfin to a hearing. Morfin greeted the wizard with his wand in one hand and a knife in the other, hissing in Parseltongue that he was not welcome. Ogden failed to understand until Marvolo appeared and restrained his son. Taking the discussion inside, Ogden explained that Morfin was summoned to a hearing on the 14th of September, but trailed off upon hearing Tom Riddle Snr and his companion Cecilia pass by, criticising the deplorable state of the Gaunt shack. Morfin almost rose from his chair with the presumed intention to attack Riddle again, but was restrained by his father. Morfin then told his father in Parseltongue that his sister was infatuated with Riddle, causing Marvolo to start to strangle Merope, ignorant of the fact that a law enforcement officer was in his very house. Ogden used a Revulsion Jinx to separate them and Morfin reacted by firing spells at the Ministry official, including a jinx that caused yellow pus to flow from Ogden's nose. Ogden fled, the returned to the Gaunt residence with several wizards, who successfully restrained both Morfin and Marvolo, placing both under arrest. The Gaunt men were sent to the Wizengamot to stand trial, whereupon Marvolo was found guilty of abusive behaviour to his daughter and obstruction of justice. Morfin was found guilty of using a hive spell on a Muggle, resisting arrest, assaulting a Magical Law Enforcmeent Officer, as well as all the earlier crimes that were outstanding. In mid-to-late 1925, Morfin was sentenced to three years in Azkaban and his father Marvolo received a six-month sentence. 
While they were incarcerated, Merope married Tom Riddle, probably by using a Love Potion on him. She died soon after giving birth to a son, Tom Marvolo Riddle. Marvolo returned from prison to an empty house and died before his son was released from Azkaban.  When Morfin finally returned, he found his father dead. He, therefore, became the last heir to the Gaunt family and inherited the shack and the family signet ring, their last heirloom. Over the years, Morfin lived in a much more deplorable state than ever, as Merope was no longer there to clean the house. Morfin let his hair grow to extreme lengths, seldom combing or styling it. He also rarely cleaned his house, letting the Gaunt residence become a state of extreme filth and squalor. Morfin's house was known for being poorly kept, filled with mould, clutter, and stale, half-eaten food which Morfin would take a long time to dispose of. Despite the squalor of the Gaunt shack, Morfin had been more self-sufficient than his father. He had managed to care for himself (albeit rather haphazardly), and presumably found a source of income to earn living, as he survived for over a decade by himself without signs of financial trouble.
Second imprisonment and death
Morfin's teenage nephew came to Little Hangleton to learn about his family in the summer of 1943. He met Morfin, who thought that this stranger looked "mighty like that Muggle", referring to the elder Tom Riddle. He told him of what transpired between the man and Merope, which infuriated Riddle Jr to the point of seeking revenge. After stunning Morfin, Tom went to Riddle's home and murdered his father, grandfather, and grandmother with the Killing Curse, using Morfin's wand. He covered up his crimes by altering Morfin's memory, causing him to believe he was the killer.
When the Ministry of Magic investigated the crime, Morfin freely admitted to it and was sentenced to life imprisonment in Azkaban. They checked Morfin's wand to see what its last spell was, and saw that it was the Killing Curse. Because of this evidence of Morfin's own, boastful confession, the Ministry saw no need to further investigation by means of Legilimency or Veritaserum. Before leaving, Tom also took the family signet ring from Morfin and wore it like a trophy at Hogwarts, which led Morfin to lament how his father would kill him for losing the ring for the rest of his life. It was eventually turned into one of Tom's Horcruxes.
Albus Dumbledore sought Morfin out in prison, and after difficultly extracting the true memory of his meeting with his nephew, determined that his memory had been tampered with. Dumbledore immediately used the true memory to appeal for Morfin's release from Azkaban. Unfortunately, by that point Morfin was weakened to such an extent that he died before he could be exonerated. He was buried beside the prison alongside the other prisoners who expired within its walls. 
Morfin was described as having thick hair matted with dirt, missing teeth, and small dark eyes that stared in opposite directions, the latter suggesting signs of strabismus. Harry thought such an appearance could be humourous, but instead Morfin looked frighteningly deranged. Upon meeting Bob Ogden, a Ministry of Magic representative, Morfin brandished both a wand in one hand and a short, bloody knife in the other. After his sister's departure and father's demise, Morfin eventually let his hair and beard grow so long that it covered his eyes and mouth. He wore the family signet ring on his right ring finger until his nephew took it.
Personality and traits
Generations of inbreeding in the Gaunt family has caused a defect within Morfin, rendering him an overall violent and deranged individual. Morfin shared the same ideology with his father and liked to torture and hex Muggles, without caring about the law, the community, or anyone else, except for his father, whom he respected, because they were both violent and pure-blood supremacists. As Merope was a blood traitor, Morfin was very disrespectful and abusive to her. After her departure from the shack, he brutally insulted her and called her a thief for stealing the locket heirloom. Furthermore, Morfin was sadistic, as he liked to torture snakes, nailing them to the door, despite his ancestor's affinity towards them. At least one snake of his suffered this fate and he threatened a second with it.
Similar to his father, Morfin was dependent on Merope in keeping the house tidy despite loathing her, as with her departure, Morfin allowed both his physical appearance and the shanty to degrade into an unrecognisable mess. Morfin, being a social outcast from the wizarding world, presumably did not throw many parties at his home nor had many guests, and as such felt little need to keep up appearances. One of his few guests, Tom Riddle, was disgusted by Morfin's slovenly appearance. Riddle had not anticipated meeting a vulgar slob when he met the Gaunt patriarch, his image of the heads of pure-blood families being akin to the likes of their ancestor or Lucius Malfoy. Ironically, Riddle's framing of his uncle caused the extinction of the pure-blood House of Gaunt. Morfin's subsequent imprisonment ruined any idea of the final patriarch of the Gaunts continuing the bloodline. Admittedly, Morfin would have probably been the last patriarch even if he lived a free man. Morfin's penury, as well as his vulgar attitude, violent disposition and slovenly personal appearance, did not make him a very desirable catch to witches looking for husbands.
Magical abilities and skills
- Non-verbal magic: Morfin was highly skilled at hexes and jinxes, and could even do them nonverbally, a skill very difficult to master. He attacked Bob Ogden with a jinx that caused yellow pus to flow from his nose without an incantation. He also cast a curse on Tom Riddle which resulted in him being covered in painful hives, though it is unknown if this one was nonverbal. He also sent a flurry of non-verbal hexes at Ogden when Ogden sent a Relashio charm to stop Marvolo Gaunt from strangling his daughter.
- Parseltongue: As with the rest of his family (His ancestor, father, sister and nephew), Morfin inherited the ability to speak to snakes from their ancestor. Morfin was proficient with the language, enough to communicate with his family and Ogden with it.
- "Dishonoured us, she did, that little slut!"
- —Morfin in regards to his sister [src]
Morfin's relationship with his family was mixed. He seemed to tolerate and maintain a tenuous relationship with his father. Morfin was very loyal to Marvolo and the family ideals about blood purity as they were both pure-blood supremacists and Marvolo was gentle enough to converse with his son in Parseltongue. He also protected his father when Bob Ogden fired a Revulsion Jinx at Marvolo to stop him from strangling Merope. However, had Marvolo been alive when Morfin lost his father's heirloom ring, their relationship would most likely have turned into a strained one, to say the least. Even though his father had died, Morfin still continued to lament how his father would kill him for losing the ring; of course, with Morfin's mental instability, this could have contributed to the delusional state he became in Azkaban. Nothing is known about Morfin's relationship with his mother since she is never seen or mentioned.
Morfin, on the other hand, was physically and verbally abusive towards his sister, Merope like his father was. He would enjoy seeing her being abused by their father and even mocked her romantic feelings of Tom Riddle Snr when he noticed her watching him. He also laughed when Marvolo tried to attack her when he revealed that she was in love with the Muggle who lived on the hill over their village when Bob Ogden visited. After Morfin was imprisoned in Azkaban, Merope was very pleased to be free from her abusers. While incarcerated during his three-year sentence, his sister married Riddle Snr, but Tom later left her while pregnant with their only child. Morfin even said that Riddle Snr leaving Merope served her right for 'marrying filth' and robbing them of Salazar Slytherin's locket, and called her a little slut who dishonoured him and Marvolo.
Tom Riddle Snr.
It is unknown if Morfin had met Tom Riddle Snr in person, but it is known that Morfin watched him from a far distance before he hexed him because he noticed his sister romantically looking at him. He most likely hated him even more when he found out that the two had gotten married. Because Morfin joined in with his father about teasing his sister being a likely Squib, he probably did not know she had the confidence to enchant Thomas Riddle. Despite his hatred for Riddle, Morfin was in agreement that Tom Riddle did the right thing in leaving Merope, albeit with a sense of schadenfreude as he caused heartbreak to Merope. Many years later, Morfin was framed for murder by his nephew by causing him to believe he killed his brother-in-law and his parents.
Tom Marvolo Riddle/Lord Voldemort
Morfin's relationship with his nephew, Tom Riddle is unknown. They did not know each other well since Riddle had spent his life in a Muggle orphanage and Morfin most likely never knew about his sister's pregnancy nor made any effort to claim guardianship of his sole blood relative. Tom Riddle didn't care about Morfin and deliberately framed him of murdering the Riddle family. Voldemort also knew that he had encountered his uncle. Tom's disdain for his uncle Morfin may have been disgust at his squalor or disdain that he never tried to raise him (akin to his father's ignorance), or a combination of both.
In the summer of 1943, Morfin seemed to not know that he had encountered his half-blood nephew (the son of his 'blood traitor sister' and the 'filthy Muggle' he attacked 18 years earlier). At the moment he saw Riddle, he thought it was Tom Riddle Snr but then realised it wasn't because he suddenly started speaking Parseltongue. Another factor that disproved the visitor from being Tom Riddle was that Morfin had left Riddle alone after his first imprisonment, but realising he would have likely had an older appearance after the passage of many years. Also many years passed After having his memory modified by his nephew, Morfin did not remember anything from the night before and was wrongfully convicted by the Ministry of Magic for the murder of Tom Riddle Snr and his parents. It could be surmised that after Albus Dumbledore discovered the truth and reinstated Morfin's proper memory of the Riddle murders, did Morfin Gaunt realise he had come into contact, and been tragically deceived, by his sister's only son.
- The name Morfin is a variaton of "Morfey", an Anglo-French surname meaning "ill-omened," or "ill-fated".
- Another variant of Morfin could come from Morpheus, the Greek god of rest and dreams, to which morphine, a powerful drug administered to people undergoing major surgery to dull pain, is based upon. In a sense of irony, Morfin's life was the antithesis of that name, being one of constant physical and emotional pain, partly of his own doing, but chiefly due to being bamboozled by his own nephew.
Behind the scenes
- Morfin and his family and even his memory of his encounter with his nephew were omitted from film adaptation of Harry Potter and the Half-Blood Prince. His entire backstory was ultimately cut from the film series.
