Kid Loki's character can be developed by showing his growth from a mischievous trickster to a more responsible hero. He could start by causing small pranks among the Avengers, but as he witnesses the real threats they face, he begins to use his skills for good. For example, his shape - shifting ability could be used not just for fun but to gather intelligence on enemies. Another way is to explore his past and how it affects his present actions. If he has a traumatic experience in Asgard, it could shape his relationships with the Avengers, like being overly cautious or overly aggressive in certain situations.
In Avengers fanfiction, Kid Loki is often portrayed as a mischievous yet endearing character. He brings his own brand of chaos, different from the more well - known Loki. He might be shown as trying to find his place among the Avengers, often getting into scrapes due to his impulsive nature and his inexperience in dealing with the 'good guys'.
One popular plot is Kid Loki's redemption arc. He starts off causing trouble for the Avengers but then gradually realizes the error of his ways and decides to use his powers for good. Another is where he gets kidnapped by an enemy of the Avengers and they have to rescue him, during which he learns to trust them.
Well, a common plot twist is when Kid Loki turns out to be the only one who can understand an ancient prophecy that involves the Avengers. This throws the whole team into chaos as they have to rely on him to figure out their next moves. Another plot twist could be that Kid Loki's mischievous acts were actually a way to test the Avengers' loyalty and strength, and in the end, he unites them in a way no one expected. Also, he might be able to transform into a powerful being that the Avengers initially thought was a different entity, and this revelation changes their battle plans entirely.
Thor would be a likely candidate. Since he is Loki's brother, he already has a connection with him. Thor might be the one to convince the other Avengers to give Loki a chance and be the first to reach out and try to befriend him in this new situation.
He would probably interact a lot with Thor. Since they are brothers, there is a pre - existing relationship full of complexity. Also, he might interact with Iron Man quite often. Tony Stark's sarcastic nature and Loki's trickery could lead to some really interesting exchanges, either in the form of verbal sparring or working together on some high - tech and magic - combined projects.
One idea could be that Loki gets turned into a vampire while in the midst of his schemes against the Avengers. This new state gives him different powers and motives. He might struggle with his newfound thirst and also use his vampire abilities to outwit the Avengers in different ways.
If Loki impersonated Thor, the real Thor would be furious when he found out. The other Avengers, like Iron Man, might initially be confused but then quickly realize something is off. Iron Man would likely use his technology to detect the impostor. Hulk might just smash first and ask questions later when he senses something wrong with 'Thor'.
One interesting Loki and Avengers fanfiction could be where Loki is forced to team up with the Avengers against a greater threat. Maybe an ancient evil that even Loki realizes is too dangerous to face alone. He grudgingly works with them, and along the way, there are lots of humorous exchanges as the Avengers don't trust him at first.
