Thorki

Thorki is the familyship between Thor Odinson and Loki from the Marvel Cinematic Universe and Marvel comics fandoms.

Thor
Thor and Loki were raised as brothers, but unknown to either one, Loki was actually born on Jotunheim and taken by Odin during a war. When Thor was to be named Odin's heir, Loki arranged an attack by the Frost Giants to sabotage the event, revealing that Thor was not ready to be king and leading to Thor's exile to Midgard (aka Earth). By the time Thor was able to return, Loki was attempting to destroy the Frost Giants to gain their father's favor, but Thor had learned the error of this, and they fought. This ended with Loki falling from the Bifrost into empty space, apparently dying before Thor's eyes.

Avengers
All of Asgard thought Loki was dead until Loki reappeared on Earth, and Thor went to Earth to return Loki and the Tesseract to Asgard. The brothers were mostly hostile with each other, and despite some attempt by Thor to reach out in the beginning, Loki was resistant and the two were unable to reconnect. Loki, and his attempt to lead an army to take over the Earth, is eventually defeated by Thor and the Avengers, and Thor brings Loki back to Asgard in chains.

Thor: The Dark World
Loki is sentence to Asgard's prison, where he stays until Thor goes to him for his help. Loki agrees, and Thor trusts him enough in this, because involves avenging the death of their mother. Thor and Loki fight side-by-side, and Loki is run-through with a sword, apparently dying in Thor's arms. This is later shown to be a trick, as Loki is alive.

Thor: Ragnarok
After being away from Asgard for some time, Thor returns to find a suspicious scene of "Odin" watching a play celebrating Loki's sacrifice, and Thor reveals that "Odin" is Loki in disguise. Thor takes Loki to Earth to find their father, who warns them of their sister Hela. Odin passes away, and Thor initially grows emotional, presumably at Loki, before Hela appears and the brothers work together against her. In a hasty retreat to Asgard, Hela knocks them both out of the bifrost and they fall, separately, to Sakaar. Loki visits Thor where he's being held as a champion fighter, and they struggle again to get along, and Loki leaves telling Thor that he's bet against him for the upcoming match. After Thor breaks out, The Grandmaster tasks Loki and Valkyrie to find Thor, and she bests Loki and presents him to Thor as a peace offering. Loki agrees to work with them to help them escape if they take him with them. He and Thor work together to get past the Grandmaster's security to commandeer a ship, but Loki attempts to betray Thor again, but Thor has prepared for this and incapacitates Loki instead. Thor leaves Sakaar to help Asgard against Hela, leaving Loki behind. Loki eventually comes to help Asgard with more fighters and with a ship large enough to evacuate the city, and he again fights side-by-side with Thor, and together they defeat Hela and save the Asgardians. Loki returns to Thor on the ship, and he is present as Thor symbolically takes a chair as king. Since the Asgardians need a new home, Thor decides to go to Earth. He and Loki later playfully chat about the problems of returning to Earth with Loki.

Avengers: Infinity War
Thanos, who was behind Loki's attempt on Earth in Avengers, intercepts the ship on their way to Earth. Thanos and his people murder half the Asgardians, and he kills Loki by breaking his neck. Before his death, Loki tells Thor, "I assure you, brother: The sun will shine on us again." Thor drags himself to hold Loki's body before their ship explodes.

Avengers: Endgame
Thor's trauma of losing Loki and so many of his people resonates in his character changes. He has gained a lot of weight, he is not much of an effective king on New Asgard which leads him to eventually give the title to Valkyrie, and he doesn't seem to be involved with any superhero activity until the new plan to gain the infinity stones through time travel.

When the Avengers go back in time, they inadvertently create branched timelines. In one, while Loki is in chains after the battle of New York, Loki picks up the tesseract and teleports away. So there is now another version of Loki in a parallel timeline, in which Loki escaped after his defeat in New York.

In another branched timeline, Loki is left in the prison on Asgard after the battle of New York, but it's left unclear if he will get out as he did in Thor: The Dark World. In this timeline, Jane Foster no longer has an infinity stone trapped inside her, this timeline's Thor does not have his hammer because the future Thor took it, and Queen Frigga is aware that Thor has traveled time and has suffered some sort of trauma. The effect of these changes on this timeline's Loki is not yet known.

Quotes
"I never wanted the throne, I only ever wanted to be your equal!"

Fanon
Interest in Thorki rose in the Marvel Cinematic Universe fandom following their introductions in the film Thor and even more following The Avengers. Most initial stories focused on the rift that's grown between them following Loki leaving Asgard, with one (typically Thor) wanting to bridge the distance and the other (typically Loki) pulling away.

For comic book fandom, the brothers have been around for decades, but interest was notably renewed with the Journey into Mystery arc featuring Kid Loki and his subsequent death and the rebirth of the original Loki in his body. Interest increased with Teen Loki in the Loki: Agent of Asgard series, which featured Loki trying to do good in his own way, and his regular run-ins with his brother. Many fanfic were written about Loki's guilt and in keeping the secret from his brother.

Many Thorki fics also ship the characters romantically. Various AUs are premised on Loki not being adopted, and so Loki and Thor would not be considered related in these instances. Arranged marriage, war, and politics are common elements.
