One common theme is identity. Loki's struggle with his Jotun identity is often explored, as he was raised in Asgard and then discovers his true Jotun nature. Another theme is acceptance, both his own acceptance of his Jotun side and how others around him accept or reject it.
One great Loki Jotun fanfiction is 'Frost and Fire'. It delves into Loki's complex relationship with his Jotun heritage in a really interesting way. The author does a wonderful job of exploring Loki's internal struggles and how his Jotun side affects his relationships with other characters in the Marvel universe.
You can try searching on fanfiction platforms like Archive of Our Own (AO3) or FanFiction.net. These websites have a vast collection of fanfictions, and by using the relevant tags such as 'Jotun Loki' and 'Jane Lemon', you may be able to find the stories you're interested in.
Another theme might be the power dynamics. Loki is a powerful being, and Jane has her own strengths, so how they interact in terms of power, whether it's Loki protecting Jane or Jane influencing Loki in some way, can be explored. For example, in some fanfictions, Jane's scientific knowledge might be a factor in how they deal with certain situations together.
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.
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.
He could meet the Frost Giants. Since he has some connection to them already, they might welcome him or at least be intrigued by his presence. He could learn more about his heritage from them and maybe even form an alliance.
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 of the well - known authors is 'MidnightSun87'. Their Loki fanfictions are really popular for their in - depth character analysis. Another great author is 'AsgardianScribe'. They have a unique way of writing Loki's dialogues that really bring the character to life. And 'FrostyFanatic' is also highly regarded for creating really engaging storylines involving Loki.
