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.
Maybe Loki is betrayed by someone he thought was a friend, and he is deeply hurt both physically and mentally. Thor discovers what has happened. He becomes extremely protective. He first takes care of Loki's wounds, using his own knowledge of healing herbs. Then he sets out to find the one who betrayed Loki. Along the way, Thor makes sure Loki feels safe and loved, constantly reassuring him that he will always be there for him. This journey not only heals Loki's physical and mental wounds but also deepens their brotherly bond.
There's also 'Loki's Redemption and Comfort'. This one focuses on Loki's self - loathing after some of his past deeds. Thor, instead of condemning him, tries to heal his brother's wounded spirit. The story has some really touching scenes where Thor shows Loki unconditional love, which slowly helps Loki to start believing in himself again.
A fanfiction idea could be that Thor becomes overprotective of Loki when they are on a mission off - world. Loki is trying to use his skills to gather information but is in a dangerous area. Thor follows him closely, ready to fight off any threats. He might even go as far as to not let Loki out of his sight for a moment. This overprotectiveness could stem from Thor's love for his brother and his newfound understanding of Loki's importance in his life, as well as in the grand scheme of things in the Avengers universe.
Loki might initially be shocked. He's used to being the one in control and causing chaos, not the one on the receiving end of pain from mortals. He could be filled with rage and vow revenge against Shield, using his wits and remaining magic to plan a counter - attack.
There could be various interpretations in such a fic. One possibility is that it shows Loki's complex character development. His childhood abuse might have led to his feelings of inferiority and envy towards Thor. For example, it could be used to explain why he sometimes acts out in a negative way, as he is constantly trying to prove himself after such a traumatic childhood.
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.
One possible fanfiction could focus on Loki's struggle with always being in Thor's shadow. Since he is the little brother, he might feel overshadowed by Thor's popularity and heroic deeds. Loki could be trying to find his own identity and purpose, distinct from just being Thor's brother. This could lead to a story where he embarks on a solo adventure, facing challenges that force him to rely on his own wits and magic, rather than Thor's strength.
A good Thor and Loki hurt/comfort fanfiction often has a deep understanding of the characters' personalities. For example, Loki is complex, often hiding his true feelings. So, when he's hurt, it should be more than just physical pain. His emotional vulnerability needs to be explored. Thor, on the other hand, is strong but also has a soft side for his brother. A story that shows Thor's patience and determination to comfort Loki is key.
Well, I read a fanfic once where Loki was framed for a crime he didn't commit. The Avengers initially suspected him but then started to dig deeper. As they uncovered the truth, they became extremely protective of Loki. It delved deep into Loki's character, showing his vulnerability and how the Avengers grew to care for him in a way that was really engaging.
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.
