You could write a fanfiction about the backstories of the Defenders. For example, delving deeper into Matt Murdock's training before he became Daredevil. This would give readers a better understanding of the characters.
Adventure is also a prevalent theme. Fanfictions often send Peter and the Defenders on exciting quests, whether it's to save a city from a new threat or to explore a mysterious realm. These adventures test their skills, both individually and as a team, and provide a lot of action - packed scenes for the readers to enjoy.
One common theme is the clash of different power levels. For instance, when the Defenders cross over with more powerful cosmic characters from the Marvel universe, like the Silver Surfer. There's also the theme of cultural differences. If they cross over with characters from a different fictional world, like a Japanese anime world, cultural differences play a big role in the story.
One common theme is cooperation. Since the two groups have different skills and backgrounds, fanfictions often focus on how they can work together. For example, the Avengers' high - tech resources combined with the Defenders' more grounded, street - level knowledge.
First, decide which character or characters you want to focus on. If you're a big Daredevil fan, start with him. Then, think of a unique situation for that character. For example, Matt Murdock having to defend a client who is secretly a supervillain's accomplice.
Another aspect is the integration of the Infinity War elements. It should feel natural, not forced. The fanfiction could explore how the Defenders react to the news of Thanos' actions, or how they might be affected by the Snap. It should also respect the existing lore of both the Defenders and the Infinity War.
One great 'Defenders Infinity War' fanfiction is 'The Defenders Unite in the Infinity War'. It has an interesting plot where the Defenders find themselves unexpectedly drawn into the events of the Infinity War. The character interactions are well - written, especially the dynamic between Daredevil and Doctor Strange.
In a spiderman defenders crossover fanfiction, the plot might involve a magical threat. Maybe an ancient evil has been awakened in the sewers of New York. Spider - Man stumbles upon it first while swinging around. He tries to fight it but quickly realizes he needs help. The Defenders, who are more in tune with the street - level, darker side of the city, are also aware of the danger. They all come together. Spider - Man can use his scientific knowledge to help figure out the origin of the threat, while the Defenders use their combat skills and street smarts to take on the minions of the ancient evil.
