Ahem. There’s no such spell in the Harry Potter books or movies, but you bet all wizards and witches would have some variation of it with the sort of monsters they have in their world! Here are ten terrifying Harry Potter fantastic beasts you definitely would not want an encounter with.
Before reading, do note that in Newt Scamander’s famous masterpiece, the term “beasts” includes a good number of intelligent, two-legged creatures we muggles typically wouldn’t consider as feral or beastly. Why this is so is clearly explained in the preface of the famed textbook.
10 Terrifying Harry Potter Fantastic Beasts You Seriously Want to Avoid
The Acromantula is an eight-eyed spider capable of human speech, with legs as long as fifteen feet. Absolutely terrifying to behold, and Ron Weasley’s worst nightmare, the creature first appeared in Harry Potter and the Chamber of Secrets.
When agitated or furious, the Acromantula also secrets venom and uses its pincers to make an incessant clicking sound. So it’s said, this clicking sound alone is enough to drive potential victims insane with fear.
Despite its fearsome exterior, though, the Acromantula is likely the least dangerous fantastic beast on this list. Its capability for human speech means it could occasionally be reasoned with, which was what happened in the books.
That said, it is still foolish to venture near any Acromantula, or worse, to try to train one. Incidentally, these intelligent Arachnids are believed to have been created by magic for the purpose of guarding secrets. For that task, few other Harry Potter fantastic beasts are more suitable.
The horrific serpentine guardian of the Chamber of Secrets, a Basilisk is bred by hatching a chicken egg underneath a toad.
It is not a natural creature, in the sense the first basilisks were created by dark wizards for nefarious purposes. According to legend, the first creator was Herpo the Foul, a Greek dark wizard. Like Voldemort, he was a Parseltongue. Herpo’s ability to speak the language of snakes was believed to have been instrumental in the control of his ghastly creation.
Apart from its size, the Basilisk has extremely venomous fangs too, as well as the ability to petrify or instantly kill with its gaze. Such abilities make the Basilisk arguably even deadlier than Medusa of Greek Mythology fame.
Of note, the Harry Potter books also established that even an Elder Wand wielding Dumbledore could not reverse the petrification caused by a Basilisk, and that Basilisk venom is strong enough to destroy Voldemort’s horcruxes. The short of it, unless you are a fluent Parselmouth, don’t even think of going near a Basilisk. And even if you are one, you need to think thrice before attempting to breed or control such a fiendish beast.
Chimaeras in the world of Harry Potter are similar to the ones found in classical Greek myths, i.e. a hybrid creature with a lion’s head, a goat’s body, and a dragon’s tail.
According to Newt Scamander, there has only ever been one successful slaying of a Chimaera, with the wizard who accomplished the feat thereafter plummeting to his death from his winged horse.
With all the things he was dealing with back then, Harry Potter should really be glad he never had to go up against a Chimaera in his quest to defeat Voldemort. This mythical creature might have succeeded in killing the boy wizard when Voldemort, dragons, and basilisks all failed.
In the original Greek myth, Bellerophon slayed the Chimaera while riding the winged-horse Pegasus. Subsequently, he fell off Pegasus, to his death, when he tried to fly to Mount Olympus.
Dragons are no strangers to fantasy fiction. What makes the ones in the world of Harry Potter exceptionally terrifying, though, is that they are completely feral.
These are no Smaugs, or Saphiras, or Elliotts, who could be deceived, reasoned with, or befriended. Dragons in Harry Potter’s world are pure engines of destruction, among the most powerful fantastic beasts known. They are an assured grisly death for anyone stupid enough to approach them unprepared.
Under Scamander’s classification, there are also ten breeds of dragons. Some are smaller and tamer, preferring diets of small animals. Others are gigantic monstrosities up to a few tons heavy.
Like their counterparts in other fantasy sagas, most organs of dragons in the Wizarding World possess practical use for magic too. For example, heartstrings could be used within wands. Because of this, the trading of dragon parts is heavily regulated by the Ministry of Magic. Even dragon eggs are classified as Class A non-tradeable goods.
The Erkling is a German, elfish creature that horrifies more with what it supposedly does, rather than what it can do.
Described as around three feet tall and with a gnomish face, the Erkling uses its magical crackle to lure children away from guardians. It then spirits away these entranced young ones for the nasty purpose of making dinner.
Probably because of the Erkling's size and lack of other abilities, the Wizarding World has been quite successful in reducing the number of Erkling killings. Nonetheless, these wicked fantastic beasts remain a significant threat to children.
Adults traveling with children in areas with known Erkling activities are thus advised to always keep an eye on their wards. If confronted by one, parents and guardians are also encouraged to smack the Erkling on the head with a hard object. Specifically, cauldrons have been said to be the most effective weapon.
The Lethifold does not rank among the most powerful fantastic beasts in Newt Scamander’s textbook. However, it is hands-down the scariest.
Also known as the Living Shroud, this heinous, supernatural murderer is a dark cloak around half an inch thick. It moves by soundlessly gliding over the ground at night. Once it finds a victim, the Lethifold kills by smothering and suffocating. Thereafter, it quietly digests the victim whole within itself. No traces of killings are ever left behind.
With wizards and witches capable of summoning fire and other deadly elements, the Lethifold might not sound that horrific a threat. The problem though is that the Lethifold favors attacking sleeping victims. Just how do you summon magical protection when you are snoring away?
There is also the unfortunate fact that the Patronus Spell is the only known spell capable of effectively repelling a Lethifold. Just imagine this. You’re asleep and suddenly, death is all over you. In your confused state, would you be able to think of a happy memory and cast the Patronus Spell? Even great wizards like Sirius Black might not be capable of the feat.
Newt Scamander described the Nundu as “arguably the most dangerous in the world.” An East African beast in the form of a giant leopard, the Nundu’s diseased breath is capable of wiping out entire villages. According to the famed Magizoologist, to subdue even one requires the combined effort of hundreds of wizards.
Interestingly, after the terrifying introduction, Newt did not further elaborate on the Nundu. In fact, the entry itself is one of the shortest in Fantastic Beasts and Where To Find Them.
This could be due to Newt having never extensively tour Africa before publishing his book. Or maybe it’s because the Nundu is indeed that deadly. In other words, there are too few survivors with reliable information. Whichever the case, this is one fantastic beast you do not want to be anywhere near to when on African soil.
J.K. Rowling possibly based the Nundu on the Mngwa or Nunda. These are ferocious, leopard-like felines said to stalk Tanzania.
Like Lethifolds and Chimaeras, Quintapeds did not appear in the original Harry Potter stories.
Otherwise known as Hairy Macboons, these terrifying fantastic beasts are carnivores with five legs, thick reddish-brown hair, and a strong appetite for human flesh. Despite the best efforts of the Ministry of Magic, not a single one has ever been captured for research.
As for the origin of the Quintapeds, they are believed to be a family of wizards transfigured into this awful form by bitters enemies.
For muggles and magical folk alike, the sole relief is that Quintapeds have ever only been found on the Scottish Isle of Drear. That isle, thankfully, has been magically made unplottable on all maps by the Ministry of Magic. There's thus no risk of you ever wandering into a Quintapeds' dinner, unless you are actually hungry to do so.
Trolls in the Harry Potter world are similar to those in other fantasy stories. As in they are huge, terribly strong, and incredibly stupid.
Originally from Scandinavia, these moronic killers have since migrated to all corners of Europe. Interestingly, all Wizarding World trolls possess some degree of human intellect, which differentiates them from many other fantastic beasts in Scamander’s book. Because of this, they could be taught to speak basic human words. They could also be made, or fooled, into being guardians of locations or treasures.
In all, Newt Scamander listed three types of trolls, one of which is the sort that lives under bridges. Despite their capacity for human speech and thought, though, trolls are still considered highly dangerous creatures because of their violent and unpredictable natures. This is made a lot worse by the fact that they are not fussy eaters.
In other words, a troll would happily gobble down prey with naught a care about whether it is a cow or a man. If you're ever confronted by a troll, do not expect to have any success reasoning with it. Your best bet for survival is to just run.
Don’t expect any sweet, worshipful Jacob Black here, or a valiant McCall. As we have seen in the movie version of Prisoner of Azkaban, werewolves in the Harry Potter world are agile supernatural killers completely undiscerning of who or what they are attacking.
Making this worst is the fact that despite all the incredible feats wizards and witches are capable of, no one has discovered a way to counter a werewolf’s bite. The best a victim could do is to regularly ingest a potion made from Wolfsbane. This doesn't stop the transformations. It merely allows the victim to retain human sentience while in canine form.
Of note, Newt Scamander describes werewolves as unique among all fantastic beasts because of their preference for human prey. A werewolf also fully remembers what he or she has done after reverting to human form – in other words, those who killed their kin or friends during rampages are doomed to remember the tragedy for the rest of their lives.
Little surprise, therefore, that werewolf victims often beg to be killed rather than to live with the curse. To be bitten by a werewolf is easily one of the worst fates to suffer in the Wizarding World.

Hey Connor. You have a point. But I felt erklings were still threatening if in large numbers.

Wow. But erklings are easy to kill so they should not be on there
