One key element is the power dynamic. Thanos is extremely powerful, with the Infinity Stones, while Peter has his spider - abilities. So, how Peter overcomes or at least contends with Thanos' power is a big part. Another element is the moral conflict. Thanos has his own warped sense of right and wrong, and Peter has his strong moral compass. Writers often explore how these two different viewpoints clash.
Character development is crucial. In these fanfictions, we usually see Peter Parker grow from a young hero to someone who can face a threat like Thanos. For Thanos, sometimes we get to see a different side of him, perhaps a bit of respect for Peter's tenacity. Also, the action scenes play a major role. Writers describe in detail how Peter uses his acrobatics and webs against Thanos' brute strength and advanced weaponry.
In a Thanos and Peter Parker fanfiction, it could be set in an alternate universe where Thanos has already won. Peter Parker is one of the few remaining heroes. He has to go undercover and try to find a way to reverse what Thanos has done. Peter uses his street - smart skills from Queens to blend in among the survivors and slowly gather information about Thanos' weaknesses. He might even form an unlikely alliance with some of Thanos' minions who have second thoughts about their master's actions.
In the fanfiction, Peter Quill Parker might have some new powers or gadgets that give him the edge. He could have studied Thanos' fighting patterns and found a way to counter them. Also, his quick thinking and ability to improvise in tough situations would play a big role. He might even use his charm to get close to Thanos and then strike when he least expects it.
One possible plot could be that Peter Parker discovers a new power within himself that gives him the edge to take on Thanos. Maybe it's a power related to the Time Stone that he manages to manipulate in a way that Thanos can't counter. He could use this power to outwit Thanos in a battle and finally deliver the killing blow.
Peter would probably be scared at first. He's just a kid, after all, and being kidnapped by a powerful being like Thanos is terrifying. But he would also be defiant. He has a strong sense of responsibility, so he might try to find a way to escape on his own.
The idea of an unlikely friendship or more can be a theme. Since they are from different worlds in the Marvel universe, seeing how they come together and form a bond, whether it's platonic or romantic, is a theme that many fanfics might explore. For example, they could team up against a common enemy that neither could face alone, and during that time, their relationship develops.
Well, it could also lead to a rescue mission. The Avengers or other superheroes might find out about Peter's kidnapping. They would then come together to form a plan to rescue him. This could involve a lot of strategizing and fighting against Thanos' forces.
There's a fanfiction called 'Peter Parker's Gambit Against Thanos'. In it, Peter realizes that brute force won't work against Thanos. So, he devises a series of clever plans. The story delves deep into Peter's character, showing his growth from a neighborhood hero to someone who can stand up to a universal threat like Thanos. It also has some really cool descriptions of Peter's web - slinging skills in the midst of the battle with Thanos.
Themes play a big part as well. Both Harry Potter and Peter Parker stories deal with themes like heroism, sacrifice, and the struggle between good and evil. In fanfiction, these themes are often intertwined and explored in new ways. For example, in a crossover, they might have to redefine what it means to be a hero in the face of threats that are both from the magical realm and the super - hero - filled streets of New York. Also, the fanfiction might explore how their different upbringings and experiences shape their understanding of these themes.
One key element is the relationship between them. It could be a friendship or a partnership. In many fanfictions, they support each other through various difficulties.
Character growth is also important. For example, Peter might learn important life lessons from May, or May could grow in her understanding of Peter's double life. This can be shown through various situations like when Peter faces a tough villain and May gives him the strength to keep going.
