One possible fanfic could be about Scott Summers and Peter Parker teaming up. Maybe they meet during a big city - wide threat that involves both mutants and non - mutants. Scott's optic blasts and Peter's spider - powers could combine in unique ways to take on the bad guys.
The plot could revolve around a scientific experiment gone wrong that affects both mutants and regular humans. Scott and Peter have to work together to find a solution. Scott's experience with mutant - related scientific issues and Peter's street - smart knowledge could be combined to stop the chaos.
One idea could be Scott dealing with his powers evolving in a new and unexpected way. Maybe he starts to see new wavelengths of light that he has to learn to control, which could lead to some really cool action scenes and internal struggles as he tries to master this new aspect of his powers.
Love and loyalty are common themes. Usually, the reader and Scott develop a deep love for each other, and they show great loyalty in the face of difficulties. For example, in many stories, when Scott is in trouble because of his mutant identity, the reader stays by his side.
Power dynamics can be a theme. If the OC has powers, how those powers interact with Scott's powers is explored. Family is another theme sometimes. The OC might come from a different family situation and how Scott and his mutant family react to that is part of the story. And of course, adventure is a common theme as they go through various challenges together.
Love and friendship are common themes. Usually, the story shows how the reader and Alex start as friends or acquaintances and then fall in love. Another theme is adventure. They might go on some sort of adventure together, like fighting against villains or exploring new places.
It's hard to say who the 'best' are as it's subjective. However, some writers who have a large following might be considered good. Check out those who are often recommended on fanfiction forums.
The main characters are Warren and Nathan. Warren may have a special talent like painting or athletics, and Nathan could have a talent for writing or something academic. Together, they bring out the best in each other in the fanfic.
Perhaps it could revolve around a mystery in their school or town. Warren and Nathan team up to solve it. They start to discover secrets about each other and their families during the investigation. They learn to trust each other more as they dig deeper into the mystery.
One common theme is friendship. They often start from a place of being at odds and then develop a deep bond. Another theme is self - growth. Nathan might learn to be more empathetic and Simon could become more confident.
