The crossover can also change the characters' relationships. If Lois Lane from 'Smallville' meets Felicity Smoak from 'Arrow', they could become friends or rivals. This would affect how the male characters, Clark and Oliver, view each other. For instance, if Lois and Felicity become rivals, it might create some tension between Clark and Oliver as they try to support their respective friends. And in terms of character growth, both Clark and Oliver would have to adapt to new social dynamics, which could lead to them becoming more well - rounded characters.
There are fanfictions that focus on the crossover during a time - travel event. For instance, Clark Kent accidentally travels to the 'Arrow' universe. There, he has to adapt to the darker and more urban setting. He could end up sharing his powers and knowledge with Oliver's team, and together they face a powerful meta - human that neither could defeat alone. This type of fanfiction often explores how different the two universes are in terms of their heroes' methods and the overall tone of their worlds.
Perhaps there could be a story where Lex Luthor somehow gets hold of some of Arrow's technology and Clark has to work with Oliver to retrieve it. They would have to combine their skills, Clark's superpowers and Oliver's archery and combat expertise.
Definitely Clark Kent and Oliver Queen. They come from different worlds but share a sense of justice. Their interactions would be fascinating as they learn from each other's methods of fighting crime. Clark could show Oliver the power of his super - abilities, while Oliver could teach Clark some of his stealth and strategic skills.
Lex Luthor would see Gotham as a new playground. He could try to manipulate some of the power players in Gotham, like the mob bosses or corrupt politicians. Batman would be on to him quickly, though. And this would lead to a cat - and - mouse game between Lex and Batman. Meanwhile, Clark would be caught in the middle, trying to figure out who to trust and how to stop Lex without causing too much collateral damage.
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.
Lois Lane in Smallville could have an interesting relationship with Supergirl. Lois might be initially skeptical of this new superhero in town. But as she sees Supergirl's selfless acts, she could become an ally and even a friend. And Clark would be in the middle, trying to make sure they both get along. Their relationships would be complex and full of growth as they interact more.
Clark and Barry would likely start off as cautious allies. Clark, being more experienced in the superhero game in a sense, might initially be a bit of a mentor to Barry. But as they face challenges together, they'd become true friends. Lois Lane would probably be intrigued by Barry's speed and his different approach to reporting. She might even try to get some scoops from him. Meanwhile, Chloe Sullivan could help Cisco Ramon with some of his tech issues, and they'd form a bond over their shared love of all things tech - savvy.
I think Rogue would be an interesting main character in a crossover. Her power - absorbing abilities could create some really unique situations, especially when she comes into contact with Clark or other powered individuals in Smallville. On the Smallville side, Lex Luthor could be a main character too. His devious nature and thirst for power could put him at odds with both the X - Men and Clark, making for a complex and engaging story.
Arrow crossover fanfiction is fan - created stories that involve characters from the 'Arrow' series crossing over with characters from other shows, universes, or even different timelines within the Arrowverse. It allows fans to explore new storylines and interactions that may not have occurred in the official canon.
I really liked a fanfic called 'Power Convergence'. In this story, the Charmed Ones end up in Smallville and they have to figure out how to get back home. Along the way, they meet Clark and his friends. It's a great read because it shows how the different power dynamics from each show would play out when the two worlds collide.
