One of the main themes is identity. Female Loki has to grapple with who she is in the chaos of Ragnarok. Another theme is redemption. In many fics, she tries to make up for past wrongs. For example, she might try to save Asgard in a different way than she did before.
One popular 'Thor Ragnarok Female Loki Fanfiction' is 'The Adventures of Female Loki in Asgard'. It explores her character in a new light, showing her dealing with the chaos of Ragnarok. Another one could be 'Female Loki's Redemption'. It's a great read as it delves into how she might find her place among the other Asgardians during that tumultuous time.
It's kind of a mixed bag. Some aspects of Thor's character and story in Ragnarok are true to the comics, but there are also significant changes and creative liberties taken.
The movie Thor: Ragnarok draws its roots from the Marvel Thor comics. It weaves together elements from different comic issues to bring the story to the big screen. The comic influence is evident in the characters, settings, and overall plot of the movie.
Well, the story of Thor Ragnarok begins with Thor being imprisoned. He discovers that his homeland Asgard is in danger because of Hela. Hela is this really strong and evil force. Thor has to fight his way out and ends up on Sakaar. There, he faces Hulk in the arena which is a wild battle. Meanwhile, Loki has been up to his usual tricks but also joins Thor in the end. Valkyrie, who had her own issues, also helps them. They return to Asgard and engage in a huge battle with Hela. It's a story full of twists, battles, and heroism.
The 'thor ragnarok graphic novel' is mainly centered around Thor's struggle during the Ragnarok. It shows how he teams up with the Hulk, Valkyrie and others. There are amazing illustrations of the epic battles, the destruction of Asgard, and Thor's attempts to save his people. It's a great way to experience the story if you are a fan of the movie or the Thor comics in general.
The back story in the Thor Ragnarok trailer shows that Thor is facing a great threat to Asgard. Hela, the goddess of death, has emerged and is bent on destruction. Thor has been away and returns to find his world in chaos. He has to fight not only Hela but also deal with being stranded on the planet Sakaar. This sets the stage for an epic battle to save Asgard and its people.
I'm not very familiar with this specific fanfic. However, generally, a fanfic about Loki and Thor might explore their complex relationship in the context of the Marvel universe. If Loki is intersex in this fanfic, it could add an interesting layer to the character's identity and how they interact with Thor.
