, Class Name , is a Saber-class Servant summoned in the Grand Orders of Fate/Grand Order. He is later summoned by Ritsuka Fujimaru.
==Profile==
===Background===
Theseus is the heroic young king of Athens who is famous for slaying the Minotauros, Asterios, by sneaking into the labyrinth of Crete with the help of Ariadne. He did not believe Asterios was a monster but because Asterios's deeds were wicked, he had to be brought down.Fate/Grand Order material II - Asterios, p.120-129, translated by Kinalvin
Theseus had also kidnapped and wed the younger sister of Penthesilea, later producing Hippolytus with her.Fate/Grand Order: Epic of Remnant - Agartha: The Mythical Subterranean Society, Section 13: Decisive Battle in El DoradoFate/Grand Order - Asclepius profile
Theseus was a relative of Heracles, and when he saw the skin of the Nemean lion that Heracles brought into his house when he was young, he did not only not run away like the other children, but he also took out a weapon; something that it's said to had shown he had the qualities of a hero.
Theseus was the son of King Aegeus of Athens, but he was born on a journey and was raised without knowing him. Theseus obtained the sword and sandals left by King Aegeus by lifting a large rock placed on top of them, and decides to take a steep and difficult overland route to meet his father. The sea route was easy, but there were various evil people lurking along the land route, and Theseus believed it was his duty as a hero to exterminate them. After defeating many villains and monsters, including the thieves Periphetes, Scyron, and Crommyonian Sow, Theseus returned to Athens in triumph, proving himself as the king's son and qualifying as his successor.
===Appearance===
During the voyage of the Argo, Theseus is described as a young man in impressive clothing. He has Ionian looks, a tropical accent, and wears an expensive Greek robe (a himation), with a royal pattern upon it.

===Personality===
Theseus has been described as a kind, friendly man with a strong sense of duty. According to Asterios' profile, he fearfully entered the Labyrinth expecting to fight a devourer of men, finding instead "a human boy desperately trying to be punished as a monster" and, after his victory over Asterios, with him on the verge of death, both talked about the blessings and curses they received reciprocally. In the end, Asterios passed away in friendly terms with Theseus, the latter never seeing the former as a monster not even once.
He claims to still love Ariadne, even after - presumably - abandoning her. He says that that as a man, he could accept and respect her choice to not bear him an heir; but as a king, he had to solve the problem by welcoming Penthesilea's younger sister as his new queen.
====Relationships====
;Asterios
:"Asterios! N-no, I'm just a normal guy. A passerby. I have nothing to do with a true hero like you... Not fooling you? Drat. I should have hidden my face."Theseus' lines translated by ComunCoutinho at Reddit 
;Euryale
:"Hey, Master. That's the Greek goddess Euryale, right? Why is she always glaring at me? Huh? She's a Servant close to Asterios? I see. That's great news. Yeah, truly. He really needed at least one person who understood him." 
;Medea/Medea Lily
:"If I had any relation to the witch of Colchis? Hmm, some legends say I do, but didn't Medea tell you that she doesn't remember much of it? Then that's either someone else with the same name or these events didn't matter to either of us." 
;Argonauts Servants
:"Long time no see, guys. Nice to see you're still doing fine. The Argonauts. How nostalgic. Is Jason still annoying as always? Great. I'm glad things seem to have stayed the same."

In Circe's interlude in Fate/Grand Order, Theseus appears as a member of the Argonauts, attempting to convince Circe to help the crew.

Circe is angry at his arrival, feeling he wronged her niece Ariadne and nephew Asterios, prompting Theseus to back off and allow Jason and Atalante to finish the conversation.Fate/Grand Order - Circe Interlude I - The Curse of the Argo
====Castle of White Sky, Castle of Black Night====
==Abilities==
Jason states that Theseus is the only member of the Argonauts that can match Heracles' might. Even if he's not, Theseus' presence was powerful enough to make Fujimaru doubt if he was a human or demigod.
He's a Saber but he doesn't care what his weapon is. He's the kind to use anything available.
