Another possibility is that a character from Glee, say Rachel Berry, discovers she has some sort of meta - human ability similar to the Flash. The Flash has to come and train her to control it while also dealing with the chaos that her new powers cause within the glee club dynamic.
One common theme is the contrast between their powers. Batman is a normal human with great skills and gadgets, while The Flash has super - speed. Fanfictions often explore how they bridge this gap to work together effectively.
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.
Sasuke would likely be aloof and guarded at first. He might see Batman as just another 'vigilante' like some of the shinobi in his world. Batman, on the other hand, would be cautious and try to figure out Sasuke's motives. Eventually, they could start sharing their combat techniques. Sasuke might show Batman how to use chakra in combat, and Batman could teach Sasuke about the importance of having a strong moral code.
One common theme is mentorship. Batman often takes on a mentorship role towards Kid Flash, guiding him on how to be a better hero. Another theme is the contrast between their powers and personalities. Batman's dark and brooding nature against Kid Flash's more light - hearted and speedy style.
Well, it could be a story where they team up to fight a common enemy. Maybe a villain who has the ability to manipulate time or something. Spiderman could use his intelligence to come up with a plan, and The Flash could quickly execute it with his speed. They would learn from each other's strengths and weaknesses along the way. For example, Spiderman could teach The Flash about using the environment to his advantage, while The Flash could show Spiderman how to move even faster in a fight.
Another theme is the combination of their powers. Many stories explore how the Arrow's combat skills and the Flash's super - speed can be used together to defeat enemies. It's like seeing two different forms of heroism merge into one strong force. This could involve them creating new strategies or tactics that are unique to their combined abilities.
One common theme is a race or a competition between the two speedsters. Since both Flash and Quicksilver are known for their super - speed, it's exciting to see them compete in a friendly or not - so - friendly race. Another theme could be them teaming up against a common enemy. They might combine their speed powers to take on a powerful villain.
