Well, Loki could save readers' lives by outwitting the villains. In many Avengers fanfiction scenarios, he has a complex and devious mind. He might predict the moves of the bad guys who are targeting the readers. By doing so, he can set traps or make counter - plans in advance, thus saving the readers. Also, his ability to teleport can be crucial in getting the readers out of harm's way quickly.
In Avengers fanfiction, Loki may save readers' lives in a rather unexpected way. He might start off as an antagonist but then have a change of heart. His powers, such as his frost magic, could be used to freeze approaching enemies or block dangerous attacks aimed at the readers. Moreover, Loki's connection to other powerful entities in the Marvel universe might be exploited to call for help when the readers are in mortal danger.
In some fanfictions, Loki might use his magic to outwit the enemies that the Avengers are facing. For example, he could create illusions to deceive the villains and lead them into a trap.
In some fanfictions, Loki saves the reader's life when they are trapped in a collapsing building during a super - powered fight. He uses his telekinesis to hold up the debris long enough for the reader to escape. This showcases his more heroic side in the fan - created stories. Another instance might be when the reader is being mind - controlled by an evil force. Loki, with his own experience in mind - games, manages to break the control and save the reader from being used as a weapon against the Avengers.
In many such fanfics, the Avengers might find Loki through various means. Sometimes it could be intelligence they gather about the location where he is being tortured. For example, they might intercept a message from Loki's captors or notice some strange energy signatures that lead them to the place.
One common theme is redemption. Loki has done a lot of bad things in the past, and when the Avengers save him, it can be seen as a step towards his redemption. For example, he might start to question his previous actions and motives. Another theme is forgiveness. The Avengers have to forgive Loki for his past wrongdoings in order to save him. This can lead to some interesting character dynamics, like Tony Stark being the most reluctant to forgive at first. Also, the theme of unexpected alliances often comes up. Loki and the Avengers are not natural allies, so their coming together in these fanfictions can create unique storylines.
One challenge could be the security around Loki. His captors might have strong defenses and guards. The Avengers would have to fight their way through to reach Loki.
There are fanfictions where Loki survives Endgame by traveling through different timelines. In these stories, he might encounter alternate versions of the Avengers and himself. For example, he could meet a younger version of Thor from a timeline where he never got banished. This would lead to a whole new set of adventures and interactions that change the course of the events in Endgame.
Thor would be a likely candidate. Since he is Loki's brother, he already has a connection with him. Thor might be the one to convince the other Avengers to give Loki a chance and be the first to reach out and try to befriend him in this new situation.
Future Loki might interact with the Avengers in a cautious way. He knows their past opinions of him and tries to prove himself. He could start by sharing small bits of useful information. For example, he might tell Iron Man about a weakness in a new enemy's technology.
They show him kindness and try to understand his motives. They offer support and help him find a better path.
He would probably interact a lot with Thor. Since they are brothers, there is a pre - existing relationship full of complexity. Also, he might interact with Iron Man quite often. Tony Stark's sarcastic nature and Loki's trickery could lead to some really interesting exchanges, either in the form of verbal sparring or working together on some high - tech and magic - combined projects.
