, Class Name , is a Saber-class Servant summoned by Ritsuka Fujimaru in the Grand Orders of Fate/Grand Order.
==Profile==
===Identity===
Born as the son of Aeson, the king of Iolcos. His given name was Diomedes, but when he was taken by Chiron, his name was changed to Jason. 
Jason argued with King , the usurper of his father's country , and eventually made him promise to return the country upon traveling far east to and returning with the Golden Fleece. The golden fleece was owned by King Aeetes 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 the mind of his daughter Medea 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 , 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 as he was crushed by the dilapidated Argo.
===Appearance===
Jason has the appearance of a handsome young man with blond hair.
===Personality===
Jason was originally overflowing in confidence, placidness, and dignity as a king, he could have been a mostly benevolent ruler. But since he couldn't become king, his confidence turned to arrogance, and his placidness shifted into complacency. Save for a few exceptions, his treatment of his subordinates is extremely sloppy But once he has his back against the wall, his instincts sharpen, and his commands become precise and accurate, much to the Argonauts' confusion. Despite this, Jason is a good man at heart, even though he treats those around him rudely and acts merciless to anyone in his way.Fate/Grand Order - Profile of Jason - translated by KonchewFate/Grand Order material IX - Jason's Profile - Translated by ComunCoutinho 
Jason's greatest skill is his charisma. A natural-born leader, Jason is even capable of convincing Heracles as a Berserker to follow his commands and in spite of lacking any genuine combat abilities, Jason was able to lead the Argonauts through his words alone.
Jason believes that humans are fundamentally foolish. That is why Jason believes someone like him has to be the one to seize power, believing himself to be much smarter than the average man. Jason seeks to make a nation where every citizen can have an education, but believes no one can ever equal his wisdom, so he has to compensate for what they lack. As long as everyone obeys him, he will give them suitable compensation and a prosperous land. A land where everyone feels safe and won't be afraid.
His relationship with his Master is more bad than good. He's boastful and incompatible with most kinds of people. On rare occasions, he can find a Master he's compatible with him, but when he does, it's when they are in the predicament of their lives.
====Relationships====
;Heracles
:"Heracles! Hey it's you, Heracles! Hahaha, ever the sourpuss! I'm actually relieved to see that! Okay, I'm leaving the rest to you. Go on and take care of everything, like usual!" Fate/Grand Order Jason's Lines
:Jason has a kind of faith in him that goes beyond love. In any world worth living, Jason will open a Cult of Heracles with wild enthusiasm.Fate/Grand Order material I Jason's Profile, translated by Reddit User ComunCoutinho.
:Jason is a fan of Heracles and is somewhat overlient on the demi-god to achieve success. He does not take Heracles's defeat, or defeat in general, very well.
;Medea
:"Gyaaah! My estranged wife! I'm sorry, but just don't turn me into a figurine! Huh? You have no intention to? Lies! Show me your workshop!!!"
:Awkward. The conversation shuts to a halt when the two are together.
:Jason and Medea are a divorced married couple. Medea initially loved him, even to the point she turned her back on her nation and family, and using all kinds of magic to achieve his goal, Jason became adverse to her and started a relationship with in a last attempt to obtain his kingdom. Feeling used and betrayed, she killed Creusa and her children as revenge before leaving him.
;Medea Lily
:"Is that the Medea that met me when I was the hero who knew no fear!? Ugh...she's cute. She's cute as always. I wanted to wait a few more years before I made her my wife... but I had no choice because of the goddess's instructions. But let's put that topic aside... Don't you think it's off-putting to know that someone would chop her brother into pieces, even for my sake? It's not my fault, right?" 
:Scary.
;Atalanta
:"I smell a cat around. Oh, it's Atalanta. Always with that irritated look on your face! No wonder kids don't like you! It's a joke! I'm just kidding, so don't draw your bow!!! GYAAAH!!!" 
;Chiron
:"Oh, it's you, professor Chiron. There's nothing you can teach me now. Not that anything would sink in to begin with! Uh, hey. Don't pull out a textbook! A backpack!? I need to wear a school backpack!?" 
:"You can do it. Jason, you can last a little longer. Persist just a little, just a tiny bit more. Be like the gum that refuses to leave your enemy's shoe."
;Asclepius
:"The smell of moist medicinal herbs... oh its you, Asclepius. You were always interested in only medicine, but I feel better if you're around. Always prioritize my medical care. And obviously put all the medical bills on a tab." 
;Dioscuri / Theseus
:"Oh...they're here too... I see a good number of the Argonauts have assembled. What do you think, Master? Dependable, huh!?" 
;Peleus
;The Argonauts crew
:"I'm the captain, guys? Can't I get some respect in here?"
:"How about you get more reliable first?"
:"My bow is a gift from the gods. Do not steal it."
:"Please try to stay awake, like the good captain you want to be."
:"Shut up and get hurt already. I'll heal you."
:They didn't care.
;The Atlantis crew
:They hit off strangely well, so Jason has his meals with them from time to time.
:In most cases, it's the crew assembling around him when Jason is eating alone.
:"Let me eat in peace, darn it!", the captain ordered, but no attempt was ever made to enforce this command.
:“Huh? What are all of you here for all of a sudden? The Neo Argonauts? Huh? I'm your leader? Well, I sure don't mind. What exactly do we do? Nothing in particular? Just hanging out? What the heck, that sounds as half-hearted as a college club. Still, though, I appreciate being the leader, so I'm in.”
==Role==
===Fate/Grand Order===
====Third Singularity: Okeanos====
Jason is summoned along with his fellow Argonauts: Medea, Heracles, and Atalanta.Fate/Grand Order - Okeanos: The Four Sealed Seas of the End - Section 12: Defeat Heracles He is convinced by Medea per Solomon's instructions that sacrificing a god to the Ark would give him absolute power.Fate/Grand Order - Okeanos: The Four Sealed Seas of the End - Section 14: Pioneer of the Stars After being told this, Jason ordered the other Argonauts to find the Ark and a god to sacrifice with exception of Atalanta who left. During their search they met Hector, who, unbeknownst to Jason, serves Solomon like Medea Lily. At some point he had Hector install himself as a double agent in Blackbeard's crew in order to capture Euryale.
Later, Jason retrieves a report from Medea that Hector has Euryale. He says they’ll search for the Ark once Hector returns. Medea suspects she’ll get an oracle of its location once he returns, which upsets Jason that she’s the only one can receive oracles. Regardless, he believes in her oracles, and himself as captain. He agrees with Medea that Chaldea cannot different the likes of the Argonauts, praising her magic and Heracles’s strength. Perturbed at Atalanta rejecting his invitation, he suspects she’s dead now, believing it’s deserved. He then orders the Argo to set sail to rendezvous with Hector.Fate/Grand Order - Okeanos: The Four Sealed Seas of the End - Section 9: Track Down the Dandies
Reaching Hector’s position, Jason launches a boulder at the Golden Hind. He surprised to see Asterios barely catch him, and wonders if he’s a werebeast. After hearing about his legend as the Minotaur, Jason merely mocks the group for lacking talent. He then threatens to have Heracles kill the group if they refuse to hand over Euryale. They refuse, so he sends Medea and Heracles to kill them. After the group kills Heracles once, Jason explains he’ll keep resurrecting until he’s killed eleven times. He is then given the Holy Grail by Hector. He then orders Heracles to kill the group, but Heracles goes after Eurayle instead. Asterios protects her from him. When Heracles ignores his orders to not kill her, Jason orders Hector to use his Noble Phantasm. After Hector’s spear impales the two Berserkers, Jason orders Heracles to capture Euryale once he resurrects. Hector however points out Asterios is still alive and is using the spear to keep a hold on Heracles. Jason orders him to go after them, but Asterios has already plunged himself and Heracles into the ocean. Angered the group will be gone by the time Heracles returns, he orders Medea to track them down. He is delighted that she already analyzed their magic circuits to track them, and they will find the Ark for them.Fate/Grand Order - Okeanos: The Four Sealed Seas of the End - Section 10: World's Oldest Pirate Ship
The Argonauts eventually locate the group. Jason orders the others to land on the island and seize both Euryale and the Ark when Chaldea's allied Archers launch their Noble Phantasms at him. In response, he orders Hector to protect, and Heracles to kill the Archers.Fate/Grand Order - Okeanos: The Four Sealed Seas of the End - Section 13: Betting It All Later, Medea tells him Heracles is dead to his disbelief. He refuses to believe it further that Chaldea killed Heracles when Francis Drake confirms what Medea said. He then orders a retreat.
The Golden Hind eventually catches up to the Argo, to Jason’s utter disbelief. Jason then uses the Grail to summon a Shadow Servant to kill the group. After it’s killed, he orders Hector to kill the group. He panics when Hector is killed, and wonders why Medea is smiling in their current situation. David then tells him that sacrificing a Divine Spirit to the Ark will cause the era to be destroyed. Confused by this, Jason asks Medea if David is lying, saying he was told sacrificing a Divine Spirit to the Ark would grant him power and invincibility. Medea answers the world’s destruction would technically make him invincible. Angered at being deceived, Jason states how he could finally create an ideal nation, a true utopia. Medea refutes his intentions and tells him he’ll never be an ideal king because his soul is hopelessly twisted. Infuriated by her words, Jason demands to know how he’s unqualified to be king since he built the Argo and gathered a crew of heroes. Medea then uses the Grail to incarnate him into Forneus, claiming it as her way of protecting him.
After Forneus and Medea are defeated, Jason is returned to normal, and demands Medea heal him. However, she cannot heal him as she herself will soon perish. Medea reveals she possesses memories of him deceiving and betraying her despite her adoration. She calls him both cruel and innocent and states that despite being weak, he attracts others to loyally serve him. She continues that since he betrays too quickly, it would be better for him to sink with the world to avoid any betrayal. Jason disappears in rage at her betrayal.
====Event: Lady Reines's Case Files====
He makes a brief appearance near the end of the recreation of Ritsuka's memory of the Third Singularity, objecting to the presence of Medea, who replaced her younger self in this fabrication. Equally unhappy with her circumstances, Medea brings an end to their hateful if comedic bickering by ending Jason herself. She celebrates being able to "finally [do] it!" as an uncomfortable Heracles looks on before they both vanish as well.Fate/Grand Order - Lady Reines's Case Files - A Time To Trick and A Time To Get Tricked
=== Final Singularity: Solomon ===
Jason was amongst the "Okeanos" Singularity Servants to aid Chaldea against Demon Gods Pillars.
====Atlantis: Ancient Ocean of the Dreadnought Gods====
Jason makes a reappearance when he and the Argonauts are summoned by the Counter Force to establish a beachhead for Chaldea's arrival. At some point during this time, The Argo comes under attack from Artemis. Heracles sacrifices himself to ensure that Jason and the Argo survive knowing that only Jason has the right charisma and ocean combat experience to help Chaldea.Fate/Grand Order: Cosmos in the Lostbelt - Atlantis: Ancient Ocean of the Dreadnought Gods - Section 5: Setting Sail Anew! He will eventually reward this faith by redeeming his past actions with his role during this Lostbelt.
Eventually, Chaldea's forces arrive and Jason joins up with Chaldea's master, in assisting with countering Odysseus's forces and using the Argo to travel around the Lostbelt. During this time he forms the Neo Argonauts with Super Orion, Mandricardo, Charlotte Corday, Achilles, Paris, Mochizuki Chiyome, and Bartholomew Roberts. He is critical as the Battle Commander for the Chaldean Forces during the final battle against Odysseus. He sacrifices himself to assist in delaying Odysseus after revealing that he had been critically wounded during the Argo's escape from Artemis and was barely hanging on. Medea had cast an illusion to make him seem normal and healthy to not drop morale.Fate/Grand Order: Cosmos in the Lostbelt - Atlantis: Ancient Ocean of the Dreadnought Gods - Section 26: Final Showdown: The Hollow Sea God
====Interlude====
Having learned from Atalanta Alter that none of the Argonauts (with the exception of Medea Lily) respects him as their captain, Jason gets the idea to recruit a new team of Argonauts so he can earn the acknowledgement he craves and coaxes Orion and Ritsuka into finding new members. He ends up hiring Arjuna Alter, Mephistopheles, Thomas Edison, Nikola Tesla, Artemis, and a shark soldier named "Jaws" whose appearance nobody can explain; he also considers hiring Elizabeth Bathory, but she changes her mind and decides to instead start the "Elizanauts" with her alternate selves.Fate/Grand Order - Jason's Interlude: Recruitment conference for The Second, possibly The Third Argonauts
Jason believes that he still needs an adjutant to help advise him and asks that Ritsuka and Orion hire all three applicants so he can choose which of them would be best. Unfortunately for him, they end up being Kriemhild, Semiramis, and a very annoyed Medea, none of which have any interest in acting as his adjutant. He immediately realizes that they plan to kill him and take control of the Argonauts for themselves, and the "clarification" that Medea actually plans to reanimate his skeleton and use it to do her chores causes him to briefly pass out from fright. However, he quickly regains his composure and proposes that if he defeats them in a battle they will have to obey him, but if they win then they can decide which of them will be the new captain.
Much to his surprise, Jason is victorious in the following battle, as his choice of words to the three had caused them to undermine each other's efforts in the hope that they could preemptively eliminate their rivals. Semiramis and Kriemhild agree to be a part of his crew, but Medea declines. When Jason tries to persuade her into joining anyway, she grumbles about how dense he is and asks him to call the new Argonauts to assemble. When he does so, he is shocked to see that he called not only his new recruits but also the original Argonauts and the Neo Argonauts.
Atalanta explains on behalf of the group that while none of them will ever respect him, they will still acknowledge him as their captain. His complaint that what he really wanted was praise and acknowledgement is quickly cut short by the arrival of the Elizanauts, and in response to their impending attack Jason begins to form a plan to fight back. As Kriemhild and Semiramis watch from afar, they are impressed by Jason's ability to earn the trust of his crew despite his lack of charisma and ambition.
Some time later, he complains to Medea Lily that the battle tired him out, but insists that she saves her healing for their Master and not him. However, he admits to her that he couldn't help but feel nostalgic about the whole endeavor and the interlude ends with Medea Lily hoping that one day he will remember his time on the Argo with pride.

==Abilities==
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 was charismatic enough organize the Argonauts into a proper crew, his power in battle does not amount to anything. True to his class, Jason wields a sword in combat.
Jason also pilots the , a ship from the Age of Gods.
 It can seemingly be operated without the need of a crew and can sail both through water and the air.
===Combat===
As a fighter, Jason's skills with the sword are mediocre despite his past training with Chiron, though they are manageable enough to allow him to hold his own for a bit. Jason's true power lies in his charisma and ability as a leader, having been the one to gather numerous Greek heroes under his leadership including the famous hero Heracles, who even listens to his commands even while summoned as a Berserker.
===Atlantic Lostbelt===

===Comment from Illustrator ===
"For the first version of his NPC design, I did a mean-faced loser, but I got told to make him hot, so I updated the design into something more good looking. To my complete surprise, he was later chosen to become a Servant, so I gave him a design themed after many different 80's rockstars. I love myself hilariously uncool guys. Also, he has a lot facial expression, just like Gof." (BLACK)
