1. Niffler (also known as the Molesnatcher)
The Niffler (Magical Beast Classification: XXX) is a fascinating creature hailing from England. These treasure hunters have a particular fondness for shiny objects, especially gold and silver. With long snouts and sleek black fur, Nifflers resemble rodents and typically reside in burrows about 20 feet underground. They can carry an astonishing amount of items in a pouch similar to a kangaroo's, which is enchanted like Hermione’s Undetectable Extension Charm in the seventh book. Despite their mischievous nature, they are gentle and affectionate toward their owners, although they will wreak havoc in search of glittering treasures. Because of this, keeping them as pets is unwise. The term "Niffler" is derived from the local dialect, meaning "to steal". Goblins at Gringotts Bank use Nifflers to dig for treasure. The Niffler also made an appearance in "Harry Potter and the Order of the Phoenix".
2. Nundu
The Nundu (Magical Beast Classification: XXXXX) is a colossal creature native to East Africa, resembling a giant leopard. Despite its enormous size, the Nundu is incredibly agile, earning it a reputation as one of the most dangerous creatures alive. Its breath is highly poisonous, powerful enough to decimate an entire village in an instant. Extremely difficult to tame, the Nundu has never been defeated by fewer than a hundred wizards working together. In comparison, even the most formidable dragons in the Triwizard Tournament can be subdued by only ten wizards. The sheer strength and power of the Nundu are unparalleled.
3. Graphorn
The Graphorn (Magical Beast Classification: XXXX) is a fierce and aggressive magical creature found in the mountains of Europe. It has a large body with a hump on its back, four short legs, and tough, grayish-purple skin that is even stronger than dragon hide, making it resistant to most spells. The Graphorn’s distinctive golden-hued, sharp horns are highly prized for use in creating potions that counteract rare poisons. This creature is known for its preference for the wild over domestication, and there are only two known Graphorns in the world today, both cared for by Newt Scamander.
4. Knarl
The Knarl (Magical Beast Classification: XXX) is a creature found in Northern Europe and North America that closely resembles a hedgehog from the Muggle world. The only difference between a Knarl and a hedgehog lies in their behavior. While a hedgehog will happily nibble on food left in the garden, the Knarl will immediately assume it is a trap and destroy the garden in its search for the food. Knarl's spiky fur is highly valued in wizarding potions. Fred and George Weasley once paid Mundungus Fletcher 6 Sickles for a bag of Knarl fur to experiment with in their store, Weasleys' Wizard Wheezes. Knarls are also fond of eating wild daisies, and potion makers often have to remove them from these plants to harvest the flowers, usually with a "Stupefy!" spell that temporarily stuns the creature without causing long-term harm.
5. Thunderbird
The Thunderbird (Magical Beast Classification: Unknown) is a large, majestic bird native to the arid climates of Arizona in the United States. Closely related to the phoenix, the Thunderbird is a symbol of one of the four houses at Ilvermorny School of Witchcraft and Wizardry. These creatures are known for creating storms as they fly and have a keen sense of impending danger. Newt Scamander owns a Thunderbird named Frank, whom he rescued from a smuggling ring in Egypt and promised to return to its native Arizona. The Thunderbird's head is described as eagle-like or, in magical terms, similar to a Hippogriff. They possess powerful wings, with Frank having a total of six. Their feathers shimmer like clouds, and they are a prominent figure in Native American mythology, especially in the Northwest regions. The Thunderbird also appears in various myths and cultures across North America, where it is said to create winds and thunderstorms when it flies. The famous American wandmaker Shikoba Wolfe once crafted a wand using Thunderbird tail feathers in the early 20th century.
6. Swooping Evil
The Swooping Evil (Magical Beast Classification: Unknown) is a large, mysterious creature with broad, blue and green wings. At first glance, it may appear to be a hybrid between a reptile and an enormous butterfly. When its wings are not spread, it adopts the behavior of a cocoon. Swooping Evils can be dangerous, as they occasionally attack by feeding on human brains. They also secrete a venom that, when brewed correctly, can be used to erase unpleasant memories, making them a valuable ingredient in certain potions.
Billywig (Classification by the Ministry of Magic: XXX) is a species of insect native to Australia. About half an inch (1.27 cm) long, it has a striking sapphire-blue body. Its wings are located at the top of its head, spinning rapidly, causing the creature to twirl as it flies. Because of this, Billywigs are rarely spotted by Muggles, and wizards only notice them when they are stung. Xenophilius Lovegood once used Billywig wings in crafting Rowena Ravenclaw's tiara, which he described as an ingredient that "enhances intellect." Billywigs also possess a thin, long stinger at the bottom of their bodies. Anyone stung by a Billywig will feel dizzy before slowly lifting off the ground, which is why many young wizards and witches in Australia seek to provoke them for the experience. However, excessive stings may lead to uncontrolled flight for days, and severe allergic reactions could result in permanent floating. Dried Billywig stingers are used in various potions and are an essential ingredient in the popular Fizzing Whizbees candy enjoyed by wizards and witches alike.
The Occamy is a two-legged, winged creature covered in feathers, with a serpentine body. A fully grown Occamy can reach up to 15 feet (4.6 meters) in length. Occamies are native to the Far East and India. Their diet consists mainly of rodents and birds, though they may occasionally "snap" at monkeys. Highly territorial, they become particularly aggressive when protecting their eggs, which are made of the purest and softest silver. The name 'Occamy' is believed to be derived from the English philosopher Occam, who proposed the 'Occam's Razor' principle, or from the Japanese word "ookami" (大神), meaning "great god". The Occamy has a unique ability to change its size depending on the space available.
The Demiguise (Classification by the Ministry of Magic: XXXX) is a peaceful, herbivorous creature native to the Far East. It possesses the ability to turn invisible and foresee the future, making it extremely difficult to capture. Only highly trained wizards and witches can detect a Demiguise. It resembles a tailless ape with large black eyes and a long, smooth coat of fur. Its skin is highly prized for its use in crafting Invisibility Cloaks, though over time these cloaks lose their potency and turn opaque. The Demiguise’s keen observational skills and prophetic abilities make it nearly impossible to capture, but the only way to do so is by performing an utterly unpredictable action, which piques its curiosity enough to approach.
The Erumpent (Classification by the Ministry of Magic: XXXX) is a magical creature native to Africa that looks like a rhinoceros. It is a powerful beast with thick skin that can resist most spells, a unique long, curved horn, and a muscular tail. African wizards are highly cautious around this creature. Though the Erumpent will never attack unless provoked, any encounter usually results in death. Its horn can puncture both skin and metal, and it contains a deadly substance that causes explosions when it makes contact. The Erumpent is now a rare species, as the male often explodes during mating season. It gives birth to only one offspring per litter. Its horn, tail, and explosive substance are commonly used in potion-making, which has led to it being classified as a restricted ingredient.
The Bowtruckle (Classification by the Ministry of Magic: XX) is a small, gentle creature, standing no taller than 8 inches (around 20 cm), about the size of a human hand. It resides within the dense branches of trees, feeding primarily on insects. The Bowtruckle resembles a tiny stick figure, with a flat face made of twigs and bark, brown eyes, and long, pointed fingers (two per hand). Due to its small size and twig-like appearance, it blends in perfectly with its environment, making it nearly impossible for most people to spot. Bowtruckles are typically found in the western regions of England, southern Germany, and Scandinavian forests. These creatures are fiercely protective of the trees they call home, especially those used for high-quality wand wood, like the Wiggentree (a magical tree related to the willow). While Bowtruckles are generally peaceful, they become extremely aggressive if anyone threatens their tree. Their sharp fingers, often used to dig out pests that harm their trees, can also be used as weapons. If someone tries to harm their tree, the Bowtruckle will drop down unexpectedly and use its fingers to scratch their eyes out. To collect wood or leaves from a tree guarded by a Bowtruckle, one can distract it with a few wood-boring beetles or fairy eggs, and quickly complete the task while it is preoccupied. In Old Scottish, 'bow' means 'to live,' while 'truckle' in Old English means 'branch.' The Bowtruckle was featured in 'Harry Potter and the Order of the Phoenix.'
