Well, Loki might be overprotective. He has seen a lot in his long life, and now that Jane is carrying his child, he would not let any harm come to her. He could use his magic to create a protective shield around her at all times. This would also cause some friction between them as Jane might feel a bit suffocated by his overprotectiveness.
The fanfiction could show how their friends react. Thor might be excited to be an uncle and offer his support. The other Asgardians could be more skeptical. On Earth, Jane's friends and colleagues would also have mixed reactions. Some might be happy for her, while others might be worried about her relationship with Loki. All these reactions would add depth to the story as Loki and Jane navigate through this new chapter of their lives.
There could be a prophecy involved. In the fanfiction, it could be foretold that their child will be a great force for good or evil. This would put a lot of pressure on them. They would have to make sure they raise the child in the right way. Loki, with his own history of being a bit of a troublemaker, would have to really step up and be a positive influence. And Jane would use her scientific knowledge to ensure the best possible care for the pregnancy.
A Loki and Jane pregnancy fanfiction could explore how their different worlds collide during this time. Asgardian customs and Midgardian (Earth) customs would be very different when it comes to pregnancy and childbirth. Loki would have to adapt to Earth's ways, like going to doctor's appointments with Jane. Jane, on the other hand, would have to deal with the fact that her child will be part - Asgardian and all that comes with it, such as potential long life and special abilities.
One possibility is that it could be a very strange and unique story. Maybe it would involve some sort of magical or other - worldly pregnancy. Loki is known for his trickery, so perhaps he got involved in a situation with the Grandmaster that led to this unexpected pregnancy in a very convoluted way.
One possibility is that they would have a contest of magic. Marvel Loki is known for his illusions and shape - shifting, but DC Loki might have some different magical abilities. They could show off their skills to each other, perhaps in a friendly sparring match at first. But then it could turn into a more serious competition as their egos get involved. DC Loki might try to prove that his magic is more powerful, while Marvel Loki would want to show off his superior trickery.
Well, Loki could cause all sorts of chaos. He might try to undermine the Avengers from within. For example, he could pretend to be Iron Man and give false orders to the team, leading them into dangerous situations. Or he could pose as Captain America and spread doubt among the Avengers about their mission and each other.
In this fanfiction, Loki might finally start to see the good in the Avengers. He could be forced to team up with them against a common enemy, perhaps an even greater threat from another realm. This situation would put Loki in a position where he has to rely on the Avengers, leading to some interesting character dynamics and potential for growth for his character.
In this fanfiction, Loki might start to learn about teamwork. He could form unexpected friendships with the Avengers. For example, he might bond with Thor over their shared past in a new way, now that they are both part of the Avengers group. He could also use his trickery skills to help the Avengers in their battles against other villains.
Well, Loki might initially be confused about what to do with the baby. He could try to find the baby's parents. Maybe he uses his magic to keep the baby safe and warm in the meantime.
Another reason could be that Loki is simply bored and causing chaos is his way of having fun. Kidnapping Jane would surely stir up a lot of trouble, especially between Thor and himself. He could be looking to prove a point, that he can still disrupt things in Thor's life even after his previous defeats.
The story could focus on the challenges they face. Maybe there are shortages of food or supplies in their area, and Kratos has to go on dangerous quests to get what Faye needs during her pregnancy. It would test his skills and his love for his family.
A lot could happen. For example, they might have to go into hiding to protect the unborn child from their enemies. Their friends could form a sort of protection squad around them. Also, Raven's pregnancy could affect her powers, either enhancing them or making them more difficult to control. Nightwing would be right by her side, trying to help her through all these changes.
