Sylkior

Sylkior is the family/poly ship between Loki Laufeyson, Sylvie Laufeydottir, and Thor Odinson from the Marvel Cinematic Universe fandom.

Canon
Loki and Thor are brothers, and Loki and Sylvie are variants of each other from alternative timelines. Due to the time-travel aspect of the Loki series, there are some variations in the canon/history of each character in this relationship.

The three characters are all Asgardian although Slyvie didn't end up growing up in Asgard as she was taken away by Time Variance Authority (TVA) early in life. Thor from the main timeline lives in the knowledge of Loki being dead. He isn't aware that there are variant versions of Loki, and that one of them is working at the TVA as a result of the Avengers doing time travel. The variant of Loki meets Sylvie while trying to stop her tampering with TVA, but ends up joining her. Sylvie never meets Thor from the main timeline, and Sylvie's relationship with Thor from her own timeline is never explained in the series.

Quotes
"God. Now I understand why Thor found this so annoying."

Fanon
Fans began taking an interest in the ship following episode 3 of the Loki series, when the romantic interest between Loki and Sylvie became apparent. Although Thor does not appear as a character in the Loki series, fans began to imagine what a relationship between the three of them would look like and the term Sylkior came into usage on social media.

Because the all three characters have never interacted together in canon, speculation about what their relationship might look like borrows elements from both the canon and fanon relationships between Loki/Thor and Loki/Sylvie. Many fans speculate that because Loki and Sylvie are two variants of the same being, Thor would recognize Sylvie as a sister. It is unknown if Sylvie had a Thor variant as a sibling in her timeline, but fans speculate that she would embrace Thor in the same way. Some fanart depicts post-Endgame Thor thrilled to have Loki and Sylvie (and sometimes other Loki variants) with him in this manner. Examples include:


 * Fanfic: Wear Your Tragedies by RedactedReader, in which post-Endgame Thor calls Sylvie "sister" and they discuss this and their relationship with Loki
 * Fanart: Family portrait by @mjarmerchant
 * Fanart: I love them & want them to be a big awkward family by @solidafg
 * Fanart: Sibling bonding time by @MysiePereira
 * Fanart: Siblings? Siblings by @octisquad

Fans who are interested in Sylkior as a romantic pairing share the belief that Thor and Sylvie would embrace each other as siblings, as well as lovers. Sylkior shippers often blend canon and fanon dynamics of Loki/Sylvie and Loki/Thor to produce Sylkior. For some, this means integrating Sylvie into the established dynamics of Thorki fanon. For others, it means integrating Thor into the established dynamics of the canon romance between Loki/Sylvie. This relationship is usually depicted as developing after the events of the Loki series, and often include a reunion between Loki and Thor after Loki's death in Avengers, Infinity War.

Examples include:


 * Fanfic: Two of a Kind and One to Spare by ambiguously, in which Loki takes Sylvie to meet Thor and it turns sexual
 * Fanfic: Lost and Sound by snack_size, in which Loki and Sylvie have an initial relationship and bring in Thor
 * Fanfic: meet your storm by maharlika, in which Loki and Thor have an initial relationship and bring in Sylvie

Depictions of the pairing are not limited to these interpretations, however. Some fans alter the canon relationships between the characters to produce alternative universes with new dynamics, such as presenting Sylvie and Thor as siblings instead of Thor and Loki, or treating Sylvie and Loki as individuals who are not alternative variants of the same being. Examples include:
 * Fanfic: take only what you need by tediousTricks (ghostlyAnarchist), in which Thor has an arranged marriage with Sylvie of Jotunheim and Loki is afraid of losing him
 * Fanfic: the envy of eden by maharlika, in which Sylvie is Thor's adoptive sibling and they bring in Loki from an omega auction

Sylkior is a relatively new rarepair whose shippers are largely drawn from the much larger Thorki and Sylki fandoms. Because both Thorki and Sylki are regular targets of harassment by antis, many Thorkis and Sylkis who do not ship Sylkior support and defend its shippers when they are harassed.
