In the fanfiction, Loki's children might have powers that are a combination of Loki's and some other unknown source. For example, they could have the power to control shadows, using them to move around unseen or even attack. They may also have the ability to communicate with animals, like a form of telepathy. And it's not out of the question that they could have some form of time - manipulation powers, though this would be extremely powerful and might be limited in some way.
They could have shape - shifting abilities like Loki. This would allow them to blend in and deceive the Avengers easily. Another possible power could be magic. Since Loki is a master of magic, his children might inherit some form of it, whether it's creating illusions or controlling elements to a certain extent.
Well, it's possible that Loki's children have the power of persuasion. They could be able to influence the minds of others, just like Loki can be very manipulative. They might also have enhanced strength or speed, not as strong as the Hulk but enough to give them an edge in a fight. And there could be some unique power related to teleportation, which would make them very difficult to track.
Well, in such a fanfiction, there could be intense battles. The Avengers might initially be on the defensive against Loki's children. Maybe Loki's children would have unique powers that the Avengers have to figure out how to counter. For example, if one of them can manipulate minds, it would cause a lot of chaos within the Avengers' ranks.
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.
I think it's a rather dark and unlikely plot point. But in some fanfictions, anything can happen!
Some of the Avengers, like Thor, might have a more complex reaction. Since he is Loki's brother, he may feel a sense of responsibility towards the children. Others like Captain America would be cautious but fair, trying to assess if they are a threat. Iron Man, on the other hand, would probably be sarcastic and make some snarky remarks while sizing them up.
One possible plot could be that the Avengers initially see Loki's children as threats. They might prepare for battle, but then discover that the children are not as evil as they expected. For example, they could be in search of a new home away from Asgard's politics and the Avengers end up helping them.
Obviously, the Avengers like Iron Man, Captain America, Thor etc. would be main characters. And Loki's children, whoever they are in the fanfiction's interpretation. Maybe there would be a new character created specifically for this story as well who becomes important in the interactions between the two groups.
Well, some of the Avengers might be shocked at first. Tony Stark could crack a joke about it to ease the tension, like 'Loki, you sly devil, when did you find the time for kids?'. Captain America would probably be more serious and concerned about what this means for the safety of the world, seeing Loki as a potential threat through his children. Thor, on the other hand, might have mixed feelings. He loves his brother despite all his wrongdoings and might be more open to getting to know his nephews or nieces.
Loki had some very interesting children in Norse mythology. For example, Fenrir, the giant wolf. Fenrir was feared because of his great strength and was eventually bound. Another of his children was Jormungandr, the world serpent that encircled the earth. And Hel, who ruled over the realm of the same name, a place for those who died of sickness or old age. These children played significant roles in Norse myths.
Loki's teenage years in Avengers fanfiction could be a time of great turmoil. He might have been struggling with feelings of inadequacy compared to Thor. It could be shown that he was constantly trying to prove himself.
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.
