In Infinity War fanfiction, Loki can be alive. Fanfic authors have the creative liberty to rewrite the events. They might bring Loki back to life using magic or some other means. For example, Loki could have faked his death and gone into hiding, only to reappear later in the story to help the heroes fight against Thanos. His survival can add an interesting twist to the story and create new interactions between characters.
One interesting plot twist could be that Loki uses his illusions not just to deceive Thanos but also to create a false Infinity Gauntlet. This would mislead Thanos and his minions, buying time for the Avengers to regroup. Another could be that Loki discovers a hidden power within himself that allows him to temporarily freeze the Infinity Stones' power, halting Thanos' plan.
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.
One way to 'fix' the situation in a fanfiction could be to have Loki's faked death in Thor: The Dark World be more thoroughly investigated by Thor. If Thor had been more suspicious and dug deeper, he might have uncovered Loki's real plan earlier. This could have led to them working together more effectively against Thanos in Infinity War, preventing some of the tragedies that occurred.
His survival would have a profound effect on the Wakandans. Shuri, being the brilliant scientist she is, would be curious about Loki's Asgardian technology and magic. Loki could offer some insights that could help Wakanda defend itself better. T'Challa, on the other hand, would have to decide whether to trust Loki or not. This could create a lot of tension within Wakanda as some would be more willing to trust him than others, and all of this would be happening while they are also facing the threat of Thanos.
If Loki survived Infinity War, it might have opened up new storylines and character developments. He could have played a crucial role in finding a way to reverse the damage or caused more chaos.
Loki's development in Infinity War fanfiction can also involve his relationships. For instance, he could form an unexpected bond with the Guardians of the Galaxy. His charm and trickery could play off their more rough - and - tumble personalities in interesting ways, leading to a change in his character as he learns from them and they from him.
A possible plot twist could be that Loki was actually working with Thanos all along, but faked his death to deceive the Avengers. This would change the whole dynamic of the story and lead to a new set of conflicts. Another twist could be that Loki's survival was part of a grand plan by Odin (who might not be truly dead) to stop Thanos from getting all the Infinity Stones.
One way Loki could survive Infinity War in fanfiction is through his shape - shifting abilities. He could have faked his own death by creating an illusion of himself being killed by Thanos while he actually slipped away. Another possibility is that Heimdall, using the last of his power, sent Loki to a hidden realm before Thanos could deal the fatal blow.
In Infinity War fanfiction, Loki could play a variety of roles. He might be a key figure in an alternate plot to stop Thanos. For example, his shape - shifting abilities could be used in clever ways to deceive Thanos or his minions. Maybe he teams up with other heroes in ways that didn't happen in the movie, like forming a secret alliance with Doctor Strange to use magic against Thanos.
