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 He could start off as a more withdrawn character, but as the fanfiction progresses, he becomes more open and confident, especially with Thor by his side.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.
For Fenrir, his size and strength are very notable. He was so powerful that the gods had to use a special chain to bind him. Jormungandr is known for its enormous length as it encircles the whole world. Hel has her unique appearance, being half - alive and half - dead, and her rule over the realm of the dead for those who didn't die in battle.
They could be from a fight with a powerful magical being. Maybe Loki tried to steal a powerful artifact from a wizard or a sorcerer, and in the process, he got injured and the scars remained.
In many Thor Loki Avengers fanfictions, Loki's character development often starts from a place of being the villain. He then gradually realizes the value of his relationships, especially with Thor. For example, in some stories, after seeing the loyalty of the Avengers to each other, he begins to question his own actions. He might start to show remorse for his past deeds like the attack on New York.
Loki might become more empathetic. Usually seen as a bit of a trickster, having a girlfriend could make him understand others' feelings better. For example, he'd have to consider her emotions when planning his schemes. He could also become more protective, using his powers not just for his own gain but to keep her safe.
Hela isn't Loki's daughter in the comic universe. Their characters have separate origins and roles. There's no established connection of that nature between them.
In this fanfic, Loki's character can be developed by giving him a backstory related to his role as an agent. Maybe he was forced into this role by some threat to Asgard. This would add depth to his character. Also, his interactions with the different Avengers, like Iron Man's sarcasm rubbing off on him, can change his personality over time. He could go from being a self - centered trickster to someone who cares about the team's well - being.
Loki's character could develop in terms of his understanding of power. Through the abuse, he realizes that power can be misused like Odin does. So he may strive to use his own power in a more just way. He might also start to question the Asgardian way of ruling which is based on Odin's actions.
