flash crossover in arrow

One great Flash and Arrow crossover fanfiction is 'The City's Heroes United'. It has a really engaging plot that combines the unique abilities and personalities of the characters from both shows. The author does a great job of making the interactions between Flash and Arrow's characters feel natural.

One common theme is teamwork. Since the Flash and Arrow are from different shows, fanfictions often focus on how they can combine their unique skills to fight a common enemy.

Another theme is friendship. The fanfictions usually explore the developing friendships between the characters from the two shows. They might start off a bit distrustful but then grow to respect and rely on each other. A lot of stories show how Oliver and Barry become closer friends through their shared adventures.

A good Flash and Arrow crossover fanfiction often has well - written character interactions. Since both shows have distinct characters with their own quirks, getting them to interact in a believable way is key. For example, Flash's light - heartedness against Arrow's brooding nature can create interesting dynamics.

Oliver Queen, or Arrow, is also highly popular. His skills with a bow and arrow, along with his brooding and complex personality, add a lot of depth to the crossovers. He is often the more serious and strategic one compared to Barry.

Another theme is the exploration of different universes. Sometimes the fanfictions will send the characters into alternate realities where they have to adapt and find their way back. This allows for a lot of creativity in terms of world - building and character development. Also, friendship is often a key theme. These heroes come from different shows but in the crossovers, they form strong bonds and support each other through tough situations.

One interesting plotline could be the Flash and Arrow teaming up to face a common enemy that has powers beyond their usual foes. For example, a meta - human with the ability to manipulate time, which forces them to use their combined skills of speed and archery in creative ways.

Another interesting idea is a mind - control situation. A powerful telepath takes control of some of the heroes and villains in their respective cities. Flash, Arrow, and Supergirl have to find a way to break the mind - control. They start by finding the source of the telepath's power. Along the way, they discover that the telepath has a tragic past that led to this misuse of power. They try to reason with the telepath while also fighting off the controlled allies and villains.

A third one is 'Crossover Crisis'. In this fanfiction, a meta - human with the power to manipulate reality causes chaos that spans both the Arrow and Flash universes. The characters from both shows have to combine their skills and resources to stop this powerful enemy. It's a long and detailed story that really delves into the relationships between the different characters.

A third one is 'Crossover Chaos'. In this story, a new villain emerges that forces the Flash and Arrow to work together in ways they haven't before. It's full of action - packed scenes, and the author does a wonderful job of exploring the different relationships between the characters from both shows.
