One idea could be Frigga teaching Baby Loki magic in a secret garden on Asgard. She could show him how to make flowers bloom with his powers. Another could be a story where Baby Loki gets lost in the palace and Frigga has to search for him while also protecting him from those in the court who might not like his mischievous nature.
One possible plot could be that baby Loki has a special power that he doesn't know how to control yet. Frigga, being his mother, tries to teach him. She might take him to a secret place in Asgard where he can practice without harming anyone. As they spend time together, Loki starts to understand his power better and also forms a stronger bond with his mother.
One plot idea could be baby Loki's discovery of his Frost Giant heritage through memories of Laufey. Maybe he has visions of Laufey's rule and his own connection to it, which starts his journey of self - discovery. Another could be Laufey somehow protecting baby Loki from Asgardian threats in a secret, magical way, leading to a complex relationship between the two.
The relationship between Frigga and Baby Loki is complex yet loving. Frigga is aware of Loki's different nature compared to Thor. She showers him with affection, but also has the difficult task of preparing him for a world that may not always accept him. She encourages his inquisitive mind and his unique abilities. At the same time, Loki looks up to Frigga with a great deal of admiration and love. He trusts her completely, which is a rare thing for Loki as he grows older and becomes more distrustful of others.
The most obvious relationship is that of a mother - son. Frigga is likely to be protective, nurturing, and guiding towards baby Loki. She would be there to comfort him when he's scared or in pain.
One plot idea could be that Baby Loki gets into some sort of magical mischief in Asgard while Thor tries to keep him out of trouble. For example, Loki might accidentally turn all the flowers in the palace gardens into snakes, and Thor has to figure out how to reverse it before the other Asgardians find out.
Maybe in the fanfiction, baby Jack Frost is a key to a powerful magic that Loki wants to control. But as he spends time with the baby, he forms an unexpected bond. They end up on an adventure together, facing off against other magical creatures who also want to get their hands on Jack Frost for his powers.
One idea could be the character dealing with the shock and secrecy of it all. Maybe she has to hide it from the Asgardian court or other powerful entities. Another could be Loki's reaction, whether he is protective or has a more complex, conflicted stance.
Well, a plot could involve Loki and Jane being accidentally transported to a parallel universe where their roles are reversed. Jane has to deal with the politics of Asgard while Loki tries to understand Earth's scientific concepts. Or, perhaps they are both caught in a time - loop where they keep repeating a day, and they have to figure out how to break it together, learning more about each other in the process.
The theme of sacrifice is also present. Frigga might sacrifice her own well - being or reputation to protect Loki. In some fanfictions, she takes risks to save Loki from danger, whether it's from external threats or from the consequences of his own actions. This shows the depth of her love for him.
Loki, on the other hand, may be portrayed as having a love - hate relationship with his mother. He respects her power and wisdom, but at the same time, he resents her for not being able to fully prevent his fall. There are also stories where Frigga tries to reach out to Loki even when he has turned to the dark side, showing her unconditional love.
