In the 'Avengers and Loki Christmas fanfiction', it could be that an ancient Christmas - themed evil force is awakened. The Avengers are initially baffled on how to deal with it as it uses Christmas magic in a malicious way. Loki, having knowledge of both magic and trickery, offers his help. Together, they go on a journey to find the source of this evil. Along the way, Loki and the Avengers have many arguments and moments of understanding. By Christmas Eve, they manage to defeat the evil force, and Loki stays with the Avengers to celebrate a well - earned Christmas, having become a sort of honorary Avenger for the time being.
In a 'gabriel is loki avengers fanfiction', the plot could start with Gabriel being mysteriously drawn to Loki's presence. He could be an angel - like being who is intrigued by Loki's mischievous nature. The Avengers, on the other hand, see Gabriel as a potential threat because of his association with Loki. As the story progresses, Gabriel could try to prove his good intentions to the Avengers while also trying to figure out Loki's true intentions. There could be a lot of internal struggle within Gabriel as he battles between his loyalty to Loki (if there is some pre - existing bond) and his desire to do what's right for the world. This could lead to a complex web of relationships and a story full of twists and turns as Gabriel tries to navigate the world of the Avengers and Loki.
It could be that Loki is in emotional pain due to being rejected by Asgard again. He's alone and suffering. The Avengers, especially those like Black Widow who understand the pain of being an outcast, reach out to him. They discover that an old enemy is planning to use Loki's vulnerable state to launch an attack on both Asgard and Earth. So they have to protect Loki and stop the enemy at the same time.
The main characters would surely include Loki, who might be the catalyst for the story. Then there's Thor, his brother, who would try to bring Loki into the Christmas spirit. Hulk could also be a main character in a funny way. Imagine Hulk trying to put up Christmas lights and accidentally destroying half of the building. And of course, the core Avengers like Hawkeye, who could be teaching Loki how to shoot arrows at Christmas - themed targets, and Vision, who might explain the deeper meaning of Christmas to Loki using his knowledge of the Mind Stone.
One plot idea could be that Loki has been captured by a powerful new enemy who wants to use his knowledge of Asgardian magic. The Avengers find out and embark on a rescue mission. Along the way, they face various traps set by the enemy. Another could be that Loki fakes his own capture to draw out a threat that he can't handle alone, and the Avengers come to his aid not knowing it's a ruse at first.
One possible plot could be that the Avengers initially see Loki's children as threats. They might prepare for battle, but then discover that the children are not as evil as they expected. For example, they could be in search of a new home away from Asgard's politics and the Avengers end up helping them.
One possible reason could be Loki's sense of isolation. In many Avengers fanfictions, Loki is often portrayed as an outsider. He may cry out of loneliness, feeling that he doesn't truly belong anywhere, not even among his own kind. Another reason might be regret. Loki has done a lot of wrongdoings in the stories, and he could be crying over the consequences of his actions, like the harm he has caused to Thor or the people of Asgard.
In this fanfiction, Loki might finally start to see the good in the Avengers. He could be forced to team up with them against a common enemy, perhaps an even greater threat from another realm. This situation would put Loki in a position where he has to rely on the Avengers, leading to some interesting character dynamics and potential for growth for his character.
In this fanfiction, Loki might start to learn about teamwork. He could form unexpected friendships with the Avengers. For example, he might bond with Thor over their shared past in a new way, now that they are both part of the Avengers group. He could also use his trickery skills to help the Avengers in their battles against other villains.
A lot of fanfiction focuses on Loki's redemption arc within the context of the Avengers. For example, Loki could be injured and the Avengers take him in instead of imprisoning him. This leads to him slowly seeing the value in their cause and starting to change his ways. He might start using his powers for good, like helping Thor understand some new magical threats, which also helps to strengthen the bond between him and the Avengers.
Another plotline might involve Loki getting caught in a time - loop within an Avengers - related adventure. He keeps reliving the same day, and each time he has to interact with the Avengers in different ways to try and break the loop. This could lead to some really comical and also tense situations as he tries to figure out what's going on while the Avengers are getting increasingly suspicious of his behavior.
