"Missy, that is where Francis Clarkson is. I took him eleven years ago and you're going to lie in his grave. He cried, you know. He cried like you are now. He was pathetic. You're all pathetic. You all think you're so great but in the end you all meet your fates at my hands."
— Steven Livingstone to Ginny Weasley, Ginny Weasley and the Waking Nightmare
The Wizarding World of Harry Potter has many vile and irredeemable villains, so it should come as no surprise that many creations by fans have villains who are just as evil.

- The Chosen Six: Fenrir Greyback is just as vile as he is in canon, perhaps even more. Furious that Magical Britain revoked all rights to werewolves, he decides to wage total war on it. To do so, he leads his pack through a campaign of mass murder, killing dozens of wizards and Muggles alike. Moving north while dodging the police and Aurors, Fenrir decides to capture Harry Potter to spread his curse to him. When Percy interposes himself, Fenrir mauls him, and later brutally attacks Hogwarts in a Suicide Attack with the explicit goal of causing as much damage as possible. A sadist who gleefully admits his crimes at his trial, Fenrir gloats that he succeeded in radicalizing more werewolves by causing the laws to be further tightened, showing that he doesn't care about his fellow werewolves any more than his fellow man.

): Steven Livingstone is a Muggle who specializes in murdering young children, taking advantage of his mobile job as a cover. Kidnapping Ginny Weasley, Livingstone reminisces about his victims while idly listening to Ginny's memories of Tom Riddle tormenting her, even going so far as to identify with the young Voldemort. When he reaches a lonely forest where he usually dumps his victims, Livingstone declares that he kills because it makes him feel powerful before trying to murder Ginny. - Le Maitre de la Mort (The Master of Death) (link): Lord Voldemort, born Tom Marvolo Riddle, is just as evil as his canon counterpart in this film depicting his rise to power. While in Hogwarts, Voldemort learns about Horcruxes and plans to use them as a way to become immortal. To this end, he murders Myrtle, then his father, then Hepzibah Smith, as well as three other random people, and uses their deaths to split his soul apart. When Voldemort and some of his followers go to Albania to get Ravenclaw's diadem, they are ambushed by the ministry. Voldemort traps Elyana Ogden and tortures her with the Cruciatus curse until she gives up the name of the one who betrayed him. Voldemort tortures Avery as punishment for betraying him and then has him killed. Years later, Voldemort has amassed a large following and is beginning his plan to take over the wizarding world and eliminate all Muggles and Muggle-borns, already being responsible for the deaths of several. Voldemort would later kill Lily and James Potter and attempt to murder their infant son, Harry.
- Methods of Rationality: Professor Quirinus Quirrell, actually Tom Morfin Riddle, is a brilliant, magically gifted sociopath regarded as pure evil by everyone aware of his true nature. In his quest for eternal life, he creates over a hundred Horcruxes, personally murdering a single person for each one. Having fully ensured his immortality, he adopts a persona of a cartoonishly evil Dark Lord he names "Voldemort" and uses it to launch a war against magical Britain. After over a decade of effortlessly crushing his enemies and committing various atrocities, Voldemort imprints his own personality onto a young toddler, resulting in Harry being "remade" in Tom Riddle's image. Ten years later, having lost his original body, Voldemort possesses an adventurer named Quirinus Quirrell—turning the man into a prisoner in his own body—and applies for the position of the Defense Against the Dark Arts Professor in Hogwarts. In order to convince Harry to abandon his idealistic ways and make the boy into his own Worthy Opponent, "Quirrell" decides to psychologically break Harry first by attempting to send Hermione to Azkaban, then by brutally murdering her in front of Harry's eyes. Once Quirrell realizes that it made Harry more dangerous than expected, he resolves to kill the boy to get rid of the one threat to his immortality.
- Nightmares of Futures Past: Lord Voldemort in the Bad Future is even more brutal and vicious than in canon, cursing his followers to die should he be killed. Realizing that Harry Potter was finding and destroying his Horcruxes, Voldemort responded by sacking Hogwarts, murdering anyone who resisted him. Over the next 13 years, Voldemort and his Death Eaters devastated much of Europe, turned Durmstrang into an Academy of Evil, and purged much of the British Isles of Muggles, including an incident where the Death Eaters burned down an orphanage and killed everyone they saw. Voldemort, taking advantage of his mental connection with Harry, would often suppress his emotions until a massacre was complete, then overwhelm Harry with his sadistic glee. When finally confronted by Harry, Voldemort boasted that he didn't need to win the duel because he'd killed everyone Harry knew and loved, with Harry eventually choosing to send his soul back in time to save everyone he cared about. In the new timeline, Voldemort's presence hangs over everything Harry does.
- Voldemort: Origins of the Heir (link): Tom Marvolo Riddle, later known as Lord Voldemort, commits the same crimes as his canon counterpart and goes beyond. One of the heirs of the four Hogwarts Founders, Riddle, sharing none of his fellow heirs' noble aspirations, is introduced professing his Fantastic Racism against Muggles to the Heir of Gryffindor Grisha McClaggen and later breaking the arm of Lazarus Smith, the Heir of Hufflepuff, after tricking him into a duel. When Lazarus retrieves Helga Hufflepuff's cup and sends it to his Aunt Hepzibah for safekeeping, Riddle kills him and then Hepzibah to obtain them himself for use as a Horcrux, taunting Hepzibah over the death of her nephew while doing so and then framing her elderly House Elf for the murder, leading to the elf's death. After Grisha and Ravenclaw's Heir Wiglaff Sigurdsson try to stop him, Riddle kills both of them, desecrating Grisha's remains for a dark ritual afterward—implicitly the creation of a Horcrux—and taking on her appearance to retrieve another one of his Horcruxes from the headquarters of Soviet Aurors. Upon obtaining said Horcrux, Riddle thanks the Aurors by slaughtering all of them whilst declaring himself "Lord Voldemort".
- What If Snape Died: Lord Voldemort is just as evil as in canon. Introduced leading 30 Death Eaters in an attack on Diagon Alley, he subjects a 5-year-old Harry Potter to the Cruciatus Curse before attempting to kill him. Failing to do so and losing his body thanks to Lily's sacrifice, he arranges years later for Percy Weasley to be tricked into accepting his old diary as a gift so that the soul fragment contained within can open the Chamber of Secrets, unleashing Salazar Slytherin's basilisk on an unsuspecting student body, and also drain Percy's life force to grant himself a body. During Harry's first year, he infiltrates Hogwarts by inhabiting the body of new Astronomy professor Quirinus Quirrell, who jinxes Harry's broom during his first Quidditch game on Voldemort's orders. When he's discovered, Voldemort tortures multiple people before trying to kill Harry one last time.
- Wish Carefully: Lord Voldemort is just as evil as his canon counterpart but even more unstable. After his side agreed to a deal with Harry Potter to create a society built on Voldemort's racist ideology, Voldemort adjusted very poorly to peacetime and various setbacks to Wizarding Britain, at one point taking to the streets and torturing anyone he saw wearing glasses. Passing laws requiring wizards and witches to receive the Dark Mark once they came of age, Voldemort frequently tortures his Death Eaters through their Dark Marks for his own amusement. All this merely accelerates the decreasing population and Generational Magic Decline present among his supporters and their offspring because nobody wants to move to a place run by an Evil Overlord, with Voldemort torturing a clerk to death for trying to warn him of that problem. Things in Wizarding Britain have gotten so bad that several Death Eaters are planning to kill Voldemort or send him to Harry so that he can kill Voldemort for them.
