Well, it's not really an appropriate genre. In the Thor and Loki relationship, while they may have their conflicts in the original stories, 'abuse' goes against the spirit of healthy character development and positive storytelling. Fanfiction should generally promote positive values and interpretations of characters.
One way is for the fanfiction platforms to actively promote positive themes. They can highlight works that focus on the brotherly bond between Thor and Loki, like their adventures together or how they overcome challenges as a team. By giving more visibility to these positive works, it can shift the focus away from the negative 'abuse' theme.
There's 'Thor's Redemption in Loki's Arms'. In this story, Thor realizes his true feelings for Loki after a series of events that nearly tear Asgard apart. It's a tale full of emotion and character development.
I really like 'A Different Path for Loki'. In this fanfiction, Loki is given a chance to redeem himself in a unique way. It's full of interesting plot twists and great dialogue between Thor and Loki. The author does a wonderful job of exploring Loki's psyche and his relationship with Thor against the backdrop of the Asgardian world.
When Thor is mean to Loki in fanfiction, it can lead to a downward spiral in their relationship. Loki, feeling constantly attacked, may lash out in more extreme ways. Thor, on the other hand, may double down on his meanness, believing it's the only way to deal with Loki. This can create a cycle of animosity where any love or brotherly bond they had is overshadowed by anger and distrust. For example, Loki could start to form alliances with Thor's enemies out of spite, and Thor would see this as confirmation of Loki's untrustworthiness, making the relationship even worse.
Thor might initially go into denial. He can't believe that Loki is truly gone. He may hold Loki's body for a long time, as if waiting for him to come back to life. Then, he could become angry. Angry at the situation, at whoever or whatever caused Loki's death. Eventually, he may find solace in the memories of Loki. Remembering the good times they had together and using those memories to move forward.
If Loki survived in Infinity War fanfiction, it could have led to a very different outcome. He might have used his trickery to deceive Thanos in some way. Maybe he could have pretended to be on Thanos' side while actually working against him. This would have added an extra layer of intrigue to the story as the other characters would have been unsure of his true motives.
These fanfictions typically show their relationship as something that has to be hidden from the rest of Asgard. It adds an element of secrecy and danger. The relationship is also often portrayed as a way for both characters to find solace in a world that doesn't always understand them. Loki's cunning and Thor's power are intertwined in a way that makes their connection unique and captivating.
One example could be a story where Loki's intersex nature adds a unique layer to his relationship with Thor. Maybe in the fanfic, Thor is initially confused but then becomes very accepting and protective of Loki. It could explore how Loki deals with his own identity in the context of Asgardian society, which might be less understanding compared to modern Earth concepts.
Well, it could start with Loki getting physically and emotionally hurt by the taunts of the other Asgardians. Thor, noticing Loki's distress, steps in to protect him. He defends Loki in front of the court and makes it clear that Loki is his brother and should be treated with respect. Then, Thor takes Loki away to a quiet place where Loki can heal. He offers Loki comfort and support, and together they start to repair their relationship which had been strained in the past.
