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.
Perhaps Loki is forced to stay in Jotunheim. There could be a powerful spell or curse that binds him to the realm. This could lead to an interesting plot where Thor has to find a way to break the spell and rescue Loki. It would also give Loki a chance to explore his identity while being stuck there.
One common theme could be redemption. After experiencing abuse, Loki might be on a journey to redeem himself or find a way to heal. Another theme could be power dynamics. The abuse might be related to power imbalances between Loki and Thor, which can be explored in different ways. And also, the theme of forgiveness could play a role, either Loki seeking forgiveness from Thor or vice versa.
Well, it can be a way to bring more diversity to the fanfic world. It allows fans to explore different aspects of Loki's character that might not be explored in the official Marvel stories.
His character could also develop in terms of his powers. Maybe the abandonment was related to his latent magical abilities. He could start exploring and mastering his powers more in the fanfic. Thor's presence could either be a hindrance or a help. If it's a help, Thor could encourage Loki to use his powers for good, which would be a big step in Loki's character development.
In a fanfiction where Loki doesn't leave Jotunheim, it could lead to a very different dynamic between him and Thor. Maybe Loki would start to fully embrace his Jotun heritage. He could form alliances with the Frost Giants that would change the power balance in the Nine Realms. Thor, on the other hand, might be faced with a difficult choice of whether to side with Loki or Asgard. This could also mean that Loki would not go through some of the traumas that led to his more villainous actions in the original story. He might find a sense of belonging on Jotunheim and work towards a new future for the realm.
Well, the concept of an 'abused' scenario in a Loki x Thor fanfic can be a tricky one in terms of ethics. On one hand, fanfic is a form of creative expression. But if it involves extreme abuse that is not in line with the general spirit of the characters, it might make some readers uncomfortable. It really depends on how it's written. If it's used as a way to explore complex emotions and character development in a nuanced way, it could be considered acceptable within the fanfic community.
There's this 'Loki x OC Fanfiction' called 'Love in the Shadows'. The OC in this story is a thief with a heart of gold. She accidentally steals from Loki and that's how their story begins. It's full of witty banter between them. The author has created a really unique OC who is not intimidated by Loki's power and status, which makes for a very engaging read.
One possible plotline could be Loki's journey of self - discovery. After being abandoned as a child, he might struggle with feelings of unworthiness. Thor could then play a role in helping Loki realize his true potential. Maybe Loki initially resents Thor for having a more 'normal' upbringing, but as the story progresses, they come to understand each other better.
One consequence could be a shift in alliances. Without Loki leaving Jotunheim, the relationship between Asgard and Jotunheim would be far more complex. The Asgardians might view Loki as a traitor, which could lead to Thor being caught in the middle. He loves his brother but also has loyalty to his home. Loki, on Jotunheim, could start to build a new identity for himself. He might use his knowledge of Asgard to strengthen Jotunheim, making it a more formidable force in the Nine Realms. This could set off a chain of events that would change the entire power structure of the realms.
