Well, in a 'Spiderman meets Batman fanfiction', they could team up to fight a common villain like the Joker and Green Goblin who have joined forces. Their different skills would make for an interesting dynamic. Spiderman's agility and web - slinging could complement Batman's detective skills and high - tech gadgets.
In my opinion, in this kind of fanfiction, there wouldn't be a more dominant character. They would balance each other out. Spiderman's youthful energy and his ability to quickly adapt to new situations could be a great asset. Batman's experience and his vast resources also can't be ignored. They would probably respect each other's skills and work together as equals, rather than one trying to dominate the other.
At first, it might be a bit rocky. Spiderman is used to his own way of doing things, and Batman has very strict rules. But over time, they would start to respect each other. Spiderman would learn from Batman's detective skills, and Batman would come to appreciate Spiderman's agility and quick thinking.
Well, it can show different versions through the eyes of the fan. For example, a fanfiction could have a version of Spiderman who has a different suit, like one made entirely of nanotechnology that can transform into different shapes. The encounter between the real Spiderman and this fan - created version could explore how different looks can affect the perception of the hero.
Perhaps in the fanfiction, a young Spiderman fan who has a special power he doesn't know about yet meets the real Spiderman. They both have to figure out how to use the fan's power to stop a group of criminals who are stealing tech from Oscorp. This would involve a lot of character development for the fan character as he discovers his abilities with Spiderman's guidance.
It could be Doctor Octopus. He might have some new, more dangerous tentacle - like devices. He decides to target both Spiderman and female Spiderman because he views them as obstacles to his scientific experiments and his desire for power. He kidnaps some innocent people to lure them into his traps and tries to defeat them in a fight.
In this fanfiction, the female Spiderman could be a huge fan of the original Spiderman. She has been following his adventures from afar. One day, she gets the chance to meet him. However, at the same time, a powerful criminal organization discovers their identities and tries to capture them both. So they have to work together to not only escape but also take down this organization that is causing harm to the city.
Well, obviously the two main characters are Batman from the normal DC universe and Flashpoint Batman. Batman is the well - known Dark Knight, a symbol of justice in Gotham. Flashpoint Batman is from an alternate timeline, with different experiences and a potentially different personality.
Another idea might be that one Batman is from the future and has come back to meet his past self. The future Batman could show the past version some new technologies and tactics, but also warn him about the potential consequences of certain actions. This could lead to self - reflection for the past Batman and a change in his approach to crime - fighting.
There are many great authors. One popular one might be those who have a deep understanding of both characters' universes. For example, some authors who have been reading the comics for years. They can capture the essence of Spider - Man's quippy nature and Batman's brooding persona really well.
