Phantasmal Species

Phantasmal Species (幻想種) is the common term used to refer to all non-human creatures that are found in legends and fantasy.

Nature
They are born from the thoughts of humans or when outside reasons cause certain life-forms to transform, but they can only survive in fantasy. Then, if it is believed that the subject of a Mystery "exists," the World permits its existence and definite affirmation of said belief is not required. There are also existences desired by the world, but not by humans, and because of this they have gradually gone into hiding and dwindled in numbers. Rather than a classification for a separate ranking for beasts, it encompasses everything from demi-humans, such as fairies and giants, to monsters, such as dragons and oni. They differ from the imaginary Demons, as they are active creatures rather than passive existences. Similarly to how magi gain power through the accumulation of knowledge, those of the Phantasmal Species become stronger through the accumulation of time. Modern Magecraft is the sum of five hundred years of study, whereas the Phantasmal Species date back to the Age of Gods. Magi that only have a mystical lineage that spans five hundred years cannot hope to match or reproduce mysteries that have accumulated thousands of years and have an existence that is on par with the five modern Magics. They embody mysteries simply by existing and it is said to be a miracle if one is simply observed.

Magical Beasts
Many of the Phantasmal Species fall into the category of Magical Beasts (魔獣), which is the common denomination for all creatures that do not fit in the ordinary biological classification for living beings and those that do not fall within the normal ecosystem. The term "beast" is a thaumaturgical term, and it does not necessarily mean quadrupedal mammals. They are true deviations from biology that cannot be explained by immature research or sudden mutations. They can be ranked into three categories, which change as the creatures age and increase in power towards becoming higher existences. The lowest rank is Monstrous Beasts (魔獣), which then change into Phantasmal Beasts (幻獣), and finally become classified as Divine Beasts (神獣).

Phantasmal Beasts of the Millennium-Rank (千年クラスの幻獣・聖獣) and Divine Beasts are equal to Magic, making them unable to even be harmed by mysteries on the level of magecraft. Rider's Pegasus, which has grown from a Monstrous Beast to a Phantasmal Beast, has even greater resistance than Saber, who can easily negate Caster's magecraft from the Age of Gods. The longer the creatures live, the further away they grow from the rest of the world. Out of the current creatures that still exist in the present era, only those whose ages are measured in centuries, rather than millennia, still remain.

Most remaining Magical Beasts are Chimeras formed from mixing different species that have existed since the Age of Gods. They live on currently undeveloped lands that cannot be reached by mankind. Those on the level of Phantasmal Beasts that existed in the past have almost all migrated to a different world presented as the "Reverse Side of the World". Divine Beasts such as Moby Dick and Typhon are more on the level of "super weapons" than actual living creatures. Members of the The Twenty-seven Dead Apostle Ancestors, like Primate Murder, a white dog born with the sole purpose of killing humans, and the Forest of Einnashe, a sentient forest that matured to the level of a phantasm specie by absorbing the blood of a Dead Apostle, also count among the Magical Beasts.

Bašmu
Bashumu (バシュム) is a large poisonous horned snake with two forelegs. It is one of the eleven demons birthed by the monster of legend, Tiamat. It is a species of Divine Beast, the top of all Phantasmal Species.

Semiramis can summon them within her Hanging Gardens of Babylon, through her Sikera Ušum Noble Phantasm. But even Semiramis wouldn’t be able to summon something so powerful in that rushed situation, so she only summoned its top-half.

Bull of Heaven
Bull of Heaven (天の牡牛),, was the greatest of divine beasts released by the god after Ishtar clung to her father in tears to obtain revenge on Gilgamesh for his insults and refusing to become her husband. It was a disaster of extreme magnitude that was clad in storms. It brought about a flood and dark clouds that covered the world, causing a seven-year famine and destruction to occur on earth. It was a beast none could stand against, bringing the downfall of Uruk. Gilgamesh and Enkidu stood against it and repelled it splendidly, binding it with his chains and destroying it with his weapon. The clouds faded and the land was saved from the flood, but Ishtar plead for their deaths due to one with a human body killing a beast of the gods being a sin. Enkidu was subsequently killed afterward because he could not resist the gods.

Chimera
Kimera are creatures of the Monstrous Beast rank that make up the majority of the Magical Beasts still left within the world. They are formed from mixing different species that have existed since the Age of Gods, and they live on currently undeveloped lands that cannot be reached by mankind.

Synthetic Beast (合成獣) is a process that artificially creates chimera. It is controlled by its master in the "Zoology" animal department of the Mage's Association. The Wolf was created with the purpose of being used catalyst to summon a Servant in the False Holy Grail War. In the Seventh Labyrinth of Caubac Alcatraz, there is a magical mechanism that changes humans into Chimera monster.

Demon Boar
Demon Boar (魔猪) is a Monstrous Beast type of Phantasmal Species. It is the reincarnation of Diarmuid Ua Duibhne half younger brother by a different father. When Diarmuid and Fionn mac Cumhaill went hunting together. Diarmuid received a deep wound from a wild boar's fangs. It is said that it eats meat, eats armor, and even greedily devouring Runes. This is reckless death itself. Not to mention heroes, even the Dragon kind suffers an embarrassing defeat. Let alone, the likes of a spear-user who was harbouring doubts. In the forest of massacre, the regrets of heroes echoes today as well.

The is a Monstrous Beast that Artemis let loose upon the earth. It looks like a wild boar, but that is merely because the lifeform that was used as its basis just happened to be a boar. Dispatched as divine punishment by the angry goddess when the king of the city-state of forgot offerings to her in a harvest festival, it was a large and brutal beast that completely destroyed the crops of Calydon. During the Calydonian Boar Hunt, it rampaged without pause, killing many Greek heroes who came from all over the country. The hero, in love with Atalanta, was the one who finished it off, but surrendered the merit to Atalanta and brought great discord to the country in doing such.

Divine Bull
Divine Bull (神牛), also called God Bull: Air-walking Thunder Bull, is the name for the creatures of the Divine Beast rank that pull Gordius Wheel. Before the seduction of Europa, the supreme god of thunder, Zeus, changed his shape into that of a bull. Due to that, what manifested as the driving force of the chariot dedicated to Zeus were Divine Beasts with a connection to him. Due to the chariot being claimed by Rider before it could be offered to Zeus, they became part of his Noble Phantasm, and he refers to them as the "Children of Zeus."

Gorgon
The Gorgon (ゴルゴン) is Medusa's form as the legendary one-eyed man-eating monster after she started to kill and devour humans. Becoming an icon of terror, her appearance was distorted, and as wishes initially formed the Gorgon sisters, they also turned her into the atrocious Gorgon of legend. Even as a Heroic Spirit and Divine Spirit, she still has the rank of "Monster - Magical Beast", making her existence that of "an anti-hero closer to a monster." As a result, the rank of her Divinity decreased to the lowest value of E-. As compensation, she received the ability of Monsters and Magical Beasts, Monstrous Strength, which would bring her closer to the form of the Gorgon the more it was used. After her death, her role as a Gorgon would be decreasing mankind's numbers.

Harpy
Harpies (妖鳥) are avarice-filled flying beasts who are known for possessing cruel habits and a cowardly nature, unable to keep from being easily led astray by their appetite. While not suited to be used as soldiers, Semiramis combines them with her Dragon Tooth Warriors to create flying warriors.

Hydra
Hydra (ヒュドラー) are serpents with nine heads. Heracles is said to have battled an immortal hydra which would grow back its heads no matter how many times they were cut down. He utilized Nine Lives to simultaneously annihilate one hundred heads with a bow in order to slay it. They breathe a potent poison, and their entire bodies are filled with it. Simply standing near an adult one will make a human's lungs begin to rot. Even a deceased juvenile is great enough to harm someone with direct contact, and though not enough to kill a Servant, could still prove harmful to one. Being poisoned was not enough to kill a Divine Spirit like Chiron, but the constant pain was enough to make him give up his Divinity and immortality to cease his torment.

Rocco Belfaban owns a juvenile Hydra preserved in formalin, a small snake with its head split in nine. It is a one-of-a-kind item in the entire world according to Kairi Sisigou, and even one-third of its selling price would surpass his house's combined estate. He is able to process it into a potent poison for use in the Great Holy Grail War.

Kelpie
Kerupī, also known as Aha-ishuke (アハ・イシュケ) is classified as Monstrous beast rank by Magi. In, it is translated as "Water Horse". The man-eating beast which was a water demon, is said to devour the flesh of girls. It is a beast that appeared in a part Britain's northern islands. It has an appearance resembled a large pale horse and it's tail was shaped like a fish's fin. A water demon which strode and ran freely on the water's surface. The Monstrous beast can change its four-legged form, into a winged ": Water Bird" shape.

Moby Dick
Mobī Dikku (モビー‧ディック) is a Divine Beast, said to be among the most famous of that classification. Its level of power is great enough to call it "more super weaponish" than a living being.

There is an enemy program that appears in the Moon Cell bearing its name, but it is unknown if it is supposed to be the same being. It is a large whale said to possess a great aura of strength, possibly being even more dangerous than Servants in combat.

Pegasus
Pegasus (天馬) are winged horses that are usually part of the Monstrous Beast Rank. They are docile creatures that do not like to fight. The Pegasus summoned by Rider is a special case that has advanced to the Phantasmal Beast Rank due to its age. Her Pegasus was originally given to her from the Greek Sea God, and after she was exterminated by Perseus, it is said that Pegasus was born out of the blood dripping from her headless neck. It has been alive since the Age of Gods, and now possesses a defensive power on the same level as a dragon and Magic Resistance far greater than that of Saber. The buffets from a Pegasus's wings are capable of generating massive shock waves, which raze infrastructure and lacerate the bodies of living beings. Due to its naturally kind nature, Rider has to use Bellerophon to force it to fight.

Sphinx
Sufinkusu originate from Egyptian mythology. Rider's Noble Phantasm "The Sphinx of Abu el-Hol" are classified as Divine Beast rank creature.

Typhon
Tyūpōn (テューポーン) is a Divine Beast, said to be among the most famous of that classification. Its level of power is great enough to call it "more super weaponish" than a living being.

Unicorn
Unicorns (一角馬) are creatures with the power to purify human souls. The Seventh Holy Scripture was made from the horn of a dead unicorn that had turned into a nature spirit. Nrvnqsr Chaos has one stored inside of his Reality Marble as one of his stronger creatures.

Vorpal Bunny
Vorpal Bunny (殺人兎) are creatures part of the Phantasmal beast species.

Demi-Human
Demi-Human (亜人) is the general term used for the likes of fairies, dwarves, and giants.

Centaurs
Centaurs (ケンタウロス) are creatures with the upper body of a human and the lower body of a horse, they commonly appear in Greek mythology. Usually, centaurs are considered both as great huntsmen who effortlessly use bows and arrows while running with their horse legs and as savage monsters who would steal anything and everything. It seems Chiron alone is regarded as a "sage" that stands out as an exception among them.

Fairies
Fairies (妖精) are extensions of the planet, nature's sense of touch, that cannot be seen by normal humans, and they lack any sort of human values. There are some fairies born wearing humans' imagination as shells, an example would be the lady of the lake. There are various different types, including those that have the power to interfere with people's memories, and others that are known to be able of crafting Noble Phantasm-level artifacts, with Arondight, Avalon, Excalibur, Gáe Buidhe serving as examples. Such artifacts are engraved with Fairy letters (妖精文字), one of the lost languages, to show they were not crafted by human hands and belong to those of another world. There are Human-Eating Fairies (食人妖精) in the Seventh Labyrinth of Caubac Alcatraz, they are Familiars around 20-30 centimeters in height.

Fairies are usually entities that cannot be seen by normal humans, however those who evolve into a magnitude where they can be perceived by people become Elementals and elemental-class incarnation becomes possible. True Ancestors who are, classified as a type of large fairy, would fall into the category of an incarnated elemental. The Foundation of fairies and Elementals are of a Mystery that cannot be reached through magecraft.

The fairies in Kara no Kyoukai are not true fairies, but rather lower-class spirits shaped after the image of woodland fairies. They are much weaker in terms of raw power, but wield a portion of the original fairies' powers due to wearing fairy-like shells.

Giants
Not much are known about Giants (巨人). David defeating the Philistine giant. Beowulf slayed.

Succubus
Succubus (サキュバス) are female demons who can drain a man's semen in order to increase their magical energy and to retain their eternal youth. They also have the abilities to regenerate themselves, to manipulate dreams, and to enhance their strength. Len, who was originally a familiar, acquired the ability of a succubus to drain people of their magical energy by manipuliating their dreams. Her more selfish and outspoken TATARI version, White Len, also possesses this ability. There are also descendants like Natalia Kaminski from the original succubi species.

Werewolf
Werewolves (ウェアウルフ) are introduced in Mahou Tsukai no Yoru. They are ordinarily classified as Magical Beasts, but the silver and gold varieties are classified as Phantasmal Beasts. They are descended from a single golden werewolf, but their society has been in decline from the modern age with the absence of new golden werewolves. There currently only seems to exist one village whose leader is silver. They live in the mountains of Northern Europe away from civilization, and it is rare for their females to get pregnant. The village came upon Lugh Beowulf, who had the appearance of a golden werewolf, and became extremely excited that he would bring about their revival. It eventually turned out that he was not a werewolf at all, but a Nature Spirit, which led to him being feared and ostracized. The werewolves eventually sold him to Touko Aozaki.

Transcendent Kind
Transcendent Kind (超越種) refers specifically to terminals separated and given form from the will of the World as a defense against the resource-plundering actions of humans. Examples of such include Elementals, Divine Spirits, Oni Kind, True Ancestors, and Dragon Kind. Despite being anti-human in origin, the Counter Force of Alaya does not target these supernatural entities, as they are extensions of the world and mediators of nature before being enemies of humanity.

In a broader meaning, Transcendent Kind refers to sentient species whose very existence occurs on a different scale from humanity. The Dead Apostles qualify as "Transcendent Kind" under this definition. Strictly speaking, however, the narrow definition explained above is more accurate; and per its criterion, Dead Apostles would merely be "self-described" as Transcendents.

Blood Worms
Blood Worms (吸血虫) are the creatures that have come to make up the body of Zouken Matou in his attempt to prolong his life. His existence is essentially a conglomerate of Crest Worms with a special appetite for human flesh and blood that combine themselves to take a human form. Despite the blood-sucking habits, he is not considered to be an actual vampire that the Church would hunt.

Curruid
Curruid (クリード) was a phantasmal beast as majestic as, with a roar that could bring forth tornadoes. It was a great sea monster lurking in the distant sea. The demon spear "Gáe Bolg" was carved from the remains of Curruid's skull. Their also exists an armour, which uses the skeleton of this sea monster.
