Jason argued with King Pelias, the usurper of his father's country Iolcos, and eventually made him promise to return the country upon traveling far east to Colchis and returning with the Golden Fleece. The golden fleece was owned by King Aeëtes of Colchis.
When Jason arrived in Colchis. Jason was supported by the Goddess Aphrodite, and upon realizing that the King of Colchis was unshakable, she decided to control Medea's mind to help Jason. Medea was made to blindly love Jason, which resulted in her betraying her father and her country for a foreigner she had never seen. Her abilities allowed her to nullify her father's magic and the enchanted fire-breathing oxen, which gave Jason the chance to obtain the Golden Fleece.
King Aeetes was infuriated, and decided to personally lead his army to capture Jason before he left the country. Aphrodite once again used Medea to assist Jason's escape by forcing her to kill her own brother, Apsyrtus. While she only knew Jason by name, her forced love caused her to board his ship, the Argo, and slice her brother into pieces right before the eyes of her pursing father. The King, overcome by grief, ordered for the collection of the pieces of his dead son, which allowed for the opportunity for the Argo to escape its pursuers.
After that, Medea, in order to let her beloved Jason sit on the throne, continued to murder any opposition with magic and strategy, but her practices disgusted Jason and caused him to gradually become adverse to her. Eventually, Jason switched his interests to another woman, going so far as to have children, which Medea could not forgive. She murdered his new wife and children with magecraft, the brokenhearted Jason undergoing a miserable last moment.
In Fate/Grand Order. Jason has a younger appearance of a young man with blond hair.
In the Studio Deen adaptation, of Fate/stay night, Jason was seen in Caster's flashback where he was marrying Creusa which later breaks Medea's heart as she was seen crying. Jason makes a brief appearance in the first season anime adaptation of Fate/stay night [Unlimited Blade Works]. It is the scene where Shirou Emiya was heading towards Ryuudou Temple, where he is being controlled by Caster, Jason was seen holding the Golden Fleece.
Jason is said to be weak to the point where it is possible to not even count him as an enemy, described by Atalanta as a "useless person". While he can be described as the "monster who organized the Argonauts" with only his eloquence and charisma, his power in battle does not amount to anything.
In the Studio Deen adaptation of Fate/stay night, Jason had the appearance of a middle aged bearded man.

Archer of “Black” [Servant]
One of the Servants of the Black camp. His true name is Chiron. He is a centaur—a half-human-half-horse race, and he is a famous great sage in Greek myth.
He has a calm and gentle personality, but though he treats his Master with respect, he won’t hold back on advice if it’s for the sake of his Master. He never scorns or despises others regardless of whether they are enemy or ally, and he is exceptionally calm among the intense and passionate heroes of Greek myth. He acted as the strategist of the Black camp and continued to support his camp day and night right until he took part in the final battle.
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.
Chiron was born from Cronus, father of the head god Zeus, and Philyra, the goddess of a certain island. However, because Cronus had copulated with her while she was turned her into a horse, Chiron was born as a half-human-half-horse centaur. (There is also the theory that they were attacked by Cronus’ wife Rhea while they were in the middle of copulating and Philyra turned into a stallion in order to run away.) Balking at the idea of giving milk to a monster like Chiron, Philyra changed her form into that of a linden tree.
Though he was never loved by his mother and father, Chiron became a sage that excelled in all forms of knowledge as he grew up. This is not necessarily unrelated to the fact that his mother’s name “Philyra” means linden tree. The leaves of linden trees can be used as restoratives, and the tree bark can be used in divination or as written boards.
After becoming an adult, Chiron began to rear the “future heroes” who implored for his tutelage from all over Greece. Besides Heracles and Achilles, the heroes who received his teaching include those like Asclepius, who later became the god of medicine, and Castor, who was sublimated as the Gemini constellation. Jason, the leader of the Argonauts who enticed Medea, is also one of his students.
On a certain day, someone shot a poison arrow at him while trying to stop a dispute between centaurs, and the poison continued to endlessly make him suffer due to his immortality, until he became the Sagittarius constellation by returning his immortality to the gods and finally received salvation. His wish for the Holy Grail while participating in the Holy Grail War is to regain his immortality. To him, it is the only gift he received from his parents.
As a Servant, his stats have received a slight rank down due to giving up his immortality and transforming his legs into those of a human, but even then he boasts of specks high enough for him to be called a first-rate Servant—to an extremely abnormal extent in a certain sense. In the first place, it appears that he taught not only swordsmanship, archery and horse-riding, but also wrestling techniques, so he is relatively experienced in moving with human feet.
With the combined effects of his skills, he can even utilize a pseudo-form of future sight, making him truly all-purpose in his abilities. If he has a weakness, it is that he lacks a decisive trump card. Against the brute force approach that throws away all wisdom or intelligence, his strong points fade away.
He deeply loves how weak and insufficient humans struggle despite their insufficiency and still try to move forward, so even if he was summoned as part of the Red camp, he would have definitely rebelled against them with the resolve to die.
Though if he were to describe it himself, he would merely answer, “This is my arrogance as a teacher, as embarrassing as it is”.
In the novels, he was mainly focused on his fight with Achilles outside of his light skirmish with Mordred. After all, Chiron was the only one capable of harming Achilles. That battle was such a great joy to him that he even forgot his true nature as a Servant, but he stood back up as a Servant again at the moment of his death and accurately dealt a fatal wound to Achilles.
 Fate/complete material III: World Material - The Servants of the Fifth Holy Grail War: Caster, p.030-031 [T]
Master: Souichirou Kuzuki
Alignment: Neutral Evil
Noble Phantasm: C
Medea, the daughter of King Aeëtes of Colchis in Greece, was a priestess taught by Hecate, the goddess of witchcraft. While she was raised without any discomfort, her fate was shaken greatly by the arrival of the ship Argo that sought the Golden Fleece.
Having fallen under the goddess Aphrodite's curse to fall in love with Jason, the Argo's captain, Medea stole the Golden Fleece from her father and attempted to flee the country together with Jason. Furthermore, to stall her father's ship that had been following them, she violently tore her brother to pieces and scattered his remains in the sea. With this, Medea lost a home she could return to, and came to be despised as a "witch" by the people. After that, Medea, in order to let her beloved Jason sit on the throne, continued to murder any opposition with magic and strategy, but her practices disgusted Jason and caused him to gradually become adverse to her. Eventually, Jason switched his interests to another woman, going so far as to have children, which Medea could not forgive. She murdered his new wife and children with magecraft, the brokenhearted Jason undergoing a miserable last moment.
Thus, Medea's obsessiveness and cruelty made calling her a "witch" appropriate, but despite committing inhuman deeds, she herself received no reward from this. Theories have been left behind that Medea, who achieved an immortal body from her devotion to the study of magecraft, became the reigning queen of the paradise, Elysium.
Having mastered magecraft from the Age of the Gods, Medea possessed extraordinary power as a magus. However, because her physical ability as a Servant was the lowest, she was at a disadvantage in battles against Servants with high Magic Resistance. Consequently, she faced the battles with basic tactics, avoiding personal combat to the best of her ability and using her Dragon Tooth Warriors as pawns. Even in combination with Kuzuki, he was the attacker and she bore the role of support with magecraft. She laid out a stratagem to summon Servant Assassin (Sasaki Kojirou) and order him to guard the Ryuudou temple gate while she gathered mana and used her own Noble Phantasm to destroy the other Servants' contracts and make them her allies.
Territory Creation: A
The ability to create a territory to gather mana is a special characteristic of the Caster class. Medea's inherent magical capacity is not that great but by expanding her territory to collect mana, it becomes possible for her to use high level magecraft. Moreover, because the place Medea selected to establish her territory is the underground limestone cave where the Greater Grail was instituted, Fuyuki City's greatest holy ground Ryuudou Temple, it is possible to gather an enormous amount of mana in a short time. She secured Ryuudou Temple as her main base solely to reserve enough mana to get Artoria and EMIYA to obey her after using "Rule Breaker" having summoning Servant Assassin independently. Furthermore, the influence of her created territory extends not only to Ryuudou Temple but also its surroundings. The rapid breakdown in the health of those inhabiting the periphery of the territory was because their life force was plundered for magical energy.
Because she understood the importance of the Ryuudou Temple territory the best, Sasaki Kojirou was ordered to guard the temple gate, and the interior was fortified so it could not be invaded easily. Furthermore, immediately following the beginning of the Holy Grail War, Medea almost never left the Ryuudou Temple, instead hiding on the grounds and raising mana. However, as soon as she made the judgment that she had collected enough magical energy for combat, she left the territory and turned on to the offensive.
Item Construction: A
Another skill granted to the Caster class. It is possible to construct enchanted tools, from implements of war to items for daily use. Many different articles can be made at will.
The dragon tooth warriors on the next page were made using this ability. In addition, it is also possible to make magical implements known as Mystic Codes. As Mystic Codes are used as devices to supplement thaumaturgy, or wielded as tools to activate specific effects during magical combat, this is a typical skill for a magus to possess. However, with an Item Construction rank of A, there is a great difference between the Mystic Codes that other magi build and the artifacts that Medea can create. Also, this skill requires time to gather components and manufacture items. This is why she spent most of her efforts on Territory Creation and focused on creating dragon tooth warriors. Though it requires preparation and planning, given enough time Item Construction has the potential to be a formidable asset.
High-Speed Divine Words: A
A skill that assists magical incantations. Normally, the length of an incantation increases with the scale of the thaumaturgy being performed, but this skill allows chants to be greatly abbreviated. It is particularly useful for direct attack magic. There are many examples of Medea personally using direct attack magic during the Holy Grail War, but in the fight against EMIYA she instantly unleashed countless blasts of light in an attack comparable to high thaumaturgy.
Caption: As long as a caster using High-Speed Divine Words has enough prana, she can continually fire powerful thaumaturgical attacks.
Golden Fleece: EX
The pelt of the golden-furred winged ram of Colchis. It contains the legend, "if thrown on the earth, a dragon will appear." Medea does not have the skill to summon the dragon, so she is unable to to do so even if she uses the Golden Fleece. This secret treasure might well have been the heart of the events that altered Medea's fate for the worse.
The Golden Fleece appears in Greek mythology, beginning with the marriage of King Athamas of Thessaly to his second wife Ino. Ino, who despised the children Athamas had with his first wife, the cloud goddess Nephele, plotted to kill the prince Phrixus by telling the king a false oracle and sacrificing the prince in a ritual. But then, Phrixus rescued his sister Helle at the altar. Helle rode a winged ram with golden fleece to safety, brought to her by Hermes, one of the Twelve Olympians. With the help of his sister, Phrixus went to Colchis, sacrificed the meat of the golden ram to Zeus, and offered its pelt to King Aeetes of Colchis. From then on, the Golden Fleece was passed down as a secret treasure of the royal house of Colchis.
Medea used many different types of magic during the Holy Grail War. Against nearby humans, she employed mind control, hypnosis, and other spells to gather intelligence and eliminate threats. She also used magic to lure Emiya Shirou into her own workshop.
In combat, she supported her Master Kuzuki Souichirou, who wielded the assassination technique "Snake." Souichirou, who seemed powerful enough to overwhelm a Servant, was actually being magically Reinforced to give him enough destructive power to damage a Servant.
Additionally, Medea used spatial teleportation whenever she was attacked. This spell was highly versatile.
Dragon Tooth Warriors
Magic that uses dragon teeth as foci to create golems. This is one of the magics Medea specialized in, passed down to the king of Colchis long ago. The combat strength of one dragon tooth soldier is no match for a Servant, and even a human Master can deal with one. However, they are dangerous in large numbers. Medea used these golems to buy time to advance her plans. The dragon tooth soldiers are not necessarily homogeneous in appearance, showing variations in the weapons they wield.
Type: Anti-Thaumaturgy Noble Phantasm
Range: 1 person
A Noble Phantasm with an ability clearly unlike that of the other Servants' Noble Phantasms. Its efficiency as a weapon is virtually nil, but it has the ability to "break" (as in, "violation of commandment" or "transgression of law") any magic on a target pierced by its blade. Targets that can be broken are contracts formed from prana, and life forms born from prana. Rule Breaker can reset the condition of the target to the state before magic was used on it. In other words, contracts formed from prana are wiped clean, and life forms created from prana are forcibly sublimated. Thus, its utility is quite limited, but it is extremely powerful within the context of the Servant system of the Holy Grail War.
In practice, Medea successfully used this Noble Phantasm to nullify the contracts between other Masters and their Servants. For a time, Artoria and EMIYA served Medea as her own Servants.
