Pixies
- Main article: Pixie
The six pixies bonded with the Winx Club.
Pixies are small, spritely creatures with relatively large heads and eyes that live together with one another in hidden villages. Born from the Tree of Life, pixies create settlements around such a sprout to ensure their survival, as only the magic from the Tree can heal them when they fall ill.
Pixies are very similar to fairies in that they possess primarily positive magic, wings and are an all-female species. In fact, pixies have been known to regularly bond with fairies to better bring out the magical potential of both parties. Bonding is such a special occasion for pixies in that one shares a mystical and magical bond with a specific fairy since birth, so a pixie cannot bond with just any fairy nor can they bond with more than one. The same holds true in reverse for fairies.
Additionally, pixies can either grow or be appointed as Guardian Pixies, or pixies that are tasked with protecting the quadrants of the Codex to ensure no one gains access to the realm of Relix and taint the Ultimate Power. Currently, the four Guardian Pixies consist of Concorda who is based in Alfea, Discorda who is based in Cloud Tower, Athena who is based in Red Fountain, and Ninfea who is based in and leads their homeland of Pixie Village.
Pixie Pets

A pair of Pixie Pets.
Pixie pets are tiny magical winged animals who often accompany fairies and pixies. They vary in size, shape and magical capabilities much like most magical creatures, except pixie pets remain fairly small. They share more in common with pixies in how they bear relatively large heads and small wings, which can sometimes be too small for certain pixie pets. Even if a pixie pet is based on a bird and already possess a pair of wings, they will still bear a pair of pixie-like wings on their backs. Pixie pets are also capable of hiding and releasing their wings for whatever situations they find themselves in.
Shadow Monsters
The Hell Mastiff Monster.
Shadow Monsters are creatures of darkness and evil created for the sole purpose of surviving, the Shadow Phoenix, Lord Darkar. They come in various shapes and sizes, each with their own names, skill sets and behaviors. These include the following monsters:
- The Hell Mastiff whom Darkar employs as the "Watchdog of Downland." With a body roughly similar to a canine's, the Spiny Monster's body is grey in color and covered in large spines like a hedgehog. It is capable of launching its spines out into any direction it wishes as an offensive attack. If the spines do not immediately slay its enemy, they will weaken them which, at the very least, will give the Spiny Monster more chances to catch them.
A pair of Tar Monsters.
- Tar Monsters, which are quadrupedal monsters with slick purple skin, long necks and no eyes. Tar Monsters regularly generate large quantities of saliva with a similar consistency to that of tar, hence their name. Their tar-like saliva is also strong enough to keep their enemies trapped for a long enough period of time for the Monsters to physically strike. Additionally, since they lack eyes, Tar Monsters may be able to "see" their surroundings through heightened hearing or through touch as their cavernous surroundings would easily carry vibrations caused by movement or even voices.
The Multi-Mouth Monster.
- The Multi-Mouth Monster, which is a being with a dark purple body covered in ravenous, fanged mouths apart from the one on its face. The monster's body is also coursing with a slime-like blood that can prevent magical beings from using their magic when poured onto them; mainly in the event that the monster is slain in battle.

Kerborg
- Main article: Kerborg
Kerborg.
Kerborg is, on his own, the weakest of Lord Darkar's shadow monsters, however, he is always seen by his master's side as the most loyal of his shadow monsters, almost as if he were his pet. A small bat-like that possesses eight legs that can also be used as wings, which give him the ability to fly, Kerborg is often sent out on reconnaissance missions and, if Darkar wishes to stir up trouble, can turn into several powerful monsters.
Kerborg as a Gregthroat.
One of these forms is known as the Gregthroat, which is a large bipedal beast with a lion's head and two serpent heads at the ends of each of its arms. Gregthroats have been noted as an extinct species but, when Kerborg takes this form, they are shown to be immune to magic. They also possess a large amount of brute strength which can also act as their greatest weakness as simply tying down a Gregthroat would force it to fight against its own strength.
Kerborg's guardian form.
Kerborg's third and final form is that of a bipedal humanoid monster much larger than the Gregthroat. His head, though masked, is horned and not at all human-like, and he possesses much tougher skin as well as bits of armor and a giant double-sided axe. With it, Kerborg can cause earthquakes and block magical attacks, showcasing that he also possesses much more strength compared to his Gregthroat form.
Trogs
- Main article: Trog
Trogs are a race of humanoid creatures that dwell underground within caverns. Two distinct types of trogs exist: those who are much larger and heavyset and those who are smaller and thinner. Each type of trog can also be born with either one set of arms or two. Due to their way of life, trogs share a notable weakness to any light that proves much brighter than the magic crystals that line their caverns. Additionally, like most humanoid races within the Magic Dimension, trogs are capable of using magic, which they use to tame Guard Worms, and live in societies ruled by monarchies. The only group of trogs shown in the series are those who reside in the Magix Underground World within the Kingdom of Downland, where Princess Amentia (Queen by the end of Season 2) currently reigns.
Guard Worms
Teredo, the Guardian of Downland.
- Main article: Guard Worm
Guard Worms are gargantuan slug-like creatures that live in caves. They bear outer shells that are as hard as stone and they make their way underground by eating any rocks or ores in their way. Guard Worms also appear to be docile creatures as they often find themselves tamed by the magic of nearby trogs, after which they are employed as their protectors. Teredo, the only Guard Worm shown in the series, is the current protector of the Kingdom of Downland.
Beavers
Much like the beavers that can be found on Earth, there exists beavers that are native to the realm of Magix (in the 4Kids dub, they are known as "Magi-Beavers"). They are known for being aggressive when disturbed as, if even one of them is disturbed, it will chew up a tree with the intent of knocking it down onto whoever bothered it, regardless of whether it was done on purpose or not.
Creature of Destruction
- Main article: Creature of Destruction
The Creature of Destruction.
The Creature of Destruction is a being that exists within legends and myths, mainly one regarding its attack on the realm of Koria on the day that the "three sacred planets," Orez, Fallat and Rot, aligned perfectly. It is also known as the "Angel of Doom" (mainly in the 4Kids dub) due to how it took the form of an angelic figure when arriving on Koria before assuming its true, more sinister form when commencing its attack.
Shapeshifting Monster
The shapeshifting monster is, as its name entails, one capable of shapeshifting with an initial form of a wolf-like creature with an upside-down body connected to a properly-aligned head. Its other form is one closer to an insectoid with wings, four arms and claws. It also showcases the ability to resist nearly all forms of magic.
It is unknown of this creature exists in the real world on its own, as its only appearance within Winx Club was as a virus monster created by Darcy and implanted into a battle simulation through her dark magic.
Quetelizardia
- Main article: Quetelizardia
A sleeping Quetelizardia.
The Quetelizardia is a large reptilian creature with a red body covered in a diamond-like pattern and large, spiked feathers. It resides within the caves of Magix's underrealm near the Kingdom of Downland and, considering how Amentia has instilled a dress code which requires its feathers as decoration, the Quetelizardia may have been living in the area for a long period of time. The Quetelizardia is also capable of breathing fire, which it uses mainly within combat when disturbed. It is also shown to be highly aggressive, as one needs to be extremely cautious when approaching.
