Loki does make a comeback in the comics. This could be due to fan demand or to further develop the character's story arc. Different comic series handle his return in various ways.
Loki's back story involves his origin as the son of Laufey. In the Norse tales, he has a reputation for being unpredictable. He gets involved in various adventures and conflicts with the gods. He is present during many important events in Norse mythology. His actions are often driven by his own self - interest or a desire to create disruption. One of the notable things about his back story is how his character evolves over time, from a mere trickster to a more complex figure whose actions have a major impact on the fate of the gods and the cosmos.
One key element is his parentage. Being the son of Laufey, a giantess, makes him different from the other gods. Another is his shape - shifting ability which he uses for his mischievous deeds. His rivalry with some of the gods, like Thor in some instances, is also important.
If Loki goes back in time, his character could develop more positively. He might learn from his past mistakes earlier and become more empathetic. For example, if he goes back to when he was causing trouble for Thor, he could see how his actions affected others and choose a different path.
A great plot idea is Loki going back to the very beginning of the creation of the Nine Realms. He might discover some long - lost secrets about the origin of power in the universe. Maybe he could find a way to harness this ancient power and use it to change his own fate and the fate of Asgard. Another idea is that he travels back to a time when he first met the Avengers. He could try to form different relationships with them, either befriending them earlier or finding a way to outwit them in a more clever way, which would completely change the events of the movies.
I'm not very familiar with this specific fanfic. However, generally, a fanfic about Loki and Thor might explore their complex relationship in the context of the Marvel universe. If Loki is intersex in this fanfic, it could add an interesting layer to the character's identity and how they interact with Thor.
Writers can also depict Loki as a character who is on a journey of self - discovery. His intersex nature is just one part of who he is, but it has a significant impact on how he views himself and his place in the world. He could start off as a more withdrawn character, but as the fanfiction progresses, he becomes more open and confident, especially with Thor by his side. The fanfic could explore how Loki's intersex identity shapes his relationships not only with Thor but also with other Asgardians.
His character could also develop in terms of his powers. Maybe the abandonment was related to his latent magical abilities. He could start exploring and mastering his powers more in the fanfic. Thor's presence could either be a hindrance or a help. If it's a help, Thor could encourage Loki to use his powers for good, which would be a big step in Loki's character development.
Loki could also show signs of fear, though he would try to hide it. Inside, he knows the power that Thanos wields. But on the outside, he would maintain a facade of bravado. His reactions would be a mix of his natural cunning and the instinct to survive in a very dangerous situation.
