One common theme is friendship. They are two very different heroes, but in fanfiction, they often form a strong bond. Another theme is cooperation, like when they team up to fight a common enemy.
There's a fanfiction called 'Allies in an Unlikely World'. In this one, they team up to face a new threat in New York. The story does a great job of showing how t'challa's skills from Wakanda and peter parker's street - smart Spiderman abilities complement each other. It also has some cool action scenes.
At first, their relationship might be a bit rocky. Peter is used to his own ways in New York, and T'Challa has his strict Wakandan values. But as time passes, they start to understand each other. T'Challa would see Peter's determination and courage, and Peter would see T'Challa's wisdom and leadership. They would bond over their shared goal of protecting the innocent.
The plot might involve Peter Parker losing his Aunt May, and T'Challa steps in as a father figure. T'Challa would introduce Peter to the Wakandan culture. Peter would then have to adapt to a new way of life. He might struggle at first with the different values and traditions but eventually grow to appreciate them. In return, Peter could share his knowledge of the streets of New York with T'Challa, which could be useful for T'Challa when dealing with international threats that have a connection to the city.
Loki is known for his mischievous nature. In this fanfiction, he could bring out a more playful side in Peter. Peter might start to use his powers in more creative and unexpected ways, like using his web - slinging not just for fighting and swinging around, but also for creating elaborate pranks, inspired by Loki. Also, Loki's manipulative side could either make Peter more distrustful of others or teach him how to spot manipulation better, depending on how their relationship develops.
At first, it would be really rocky. Peter would be very wary of Venom given their past encounters. But as Venom shows his more caring side in the adoption, Peter would start to trust him a bit. They'd have to learn to communicate, which would be difficult because of Venom's different way of thinking.
In a 'Loki adopts Peter Parker' fanfiction, Loki might teach Peter some of his trickster ways. Maybe he'd show Peter how to deceive enemies in a more magical way than just using his Spidey - sense. For example, Loki could teach Peter how to create illusions to confuse villains during a fight.
Perhaps the plot involves Venom sensing that Peter has a pure heart despite their initial differences. Venom adopts Peter because he realizes Peter is alone in the world after some tragic event in the fanfiction. Venom then tries to teach Peter how to use his powers in a more aggressive way, which Peter is initially hesitant about but later comes to understand. This could lead to Peter becoming a more formidable Spider - Man with Venom's influence.
There could also be other characters like Happy Hogan. He might play a role in helping Tony take care of Peter, like driving him to school or keeping an eye on him when Tony is busy. And perhaps Aunt May could still be in the picture, adding an interesting layer to the story as she and Tony interact regarding Peter's upbringing.
One common theme is family. Bucky, who has lost so much, finds a new family in Peter, and Peter, who is an orphan, gets a father - like figure. Another theme is mentorship. Bucky uses his skills and experiences to mentor Peter in both his normal life and his superhero life.
