A key aspect of writing good character interaction is to create conflict within the interaction that is true to the characters. For instance, if Ward from Agents of Shield were to interact with Malcolm Merlyn from Arrow, there would be a lot of mistrust and power - plays. Ward is a complex and often untrustworthy character, and Merlyn is a master manipulator. Their interaction could start with them trying to outwit each other. But then as the story progresses, they might find that they need to work together. Also, consider the emotional states of the characters. If someone like Laurel from Arrow has just lost a loved one and is interacting with an empathetic Agent from Agents of Shield, that emotional connection can add depth to their interaction.
To write a good character interaction in an Arrow and Agents of Shield crossover fanfiction, first understand each character's personality. For example, Oliver Queen is very brooding and focused on justice in his own way. Agents of Shield characters like Coulson are more about the big picture and following S.H.I.E.L.D. protocol. So when they interact, there might be some clashes at first. But also find common ground. Maybe they both care about protecting the innocent. Let the characters learn from each other. Oliver could learn about the larger scale threats that Agents of Shield deals with, and Coulson could see the value of Oliver's more hands - on approach.
When writing an Agents of Shield crossover fanfiction, think about how the different technologies and magic systems (if applicable) will interact. If you're crossing over with a fantasy world, how will the Shield agents deal with magic? And how will the magical beings react to the high - tech gadgets? Also, focus on the character development. Let the characters from both universes grow and change as a result of their interactions. You can start with a small event that escalates into a big adventure for all of them.
First, you need to understand the characters well. For Supergirl, know her powers, her moral code, and her relationships. For Agents of Shield characters, like Coulson, Daisy, etc., study their personalities and abilities. Then, create a believable scenario for their meeting. It could be something like a shared threat or an accident that brings them together.
To write a compelling character interaction, first understand the personalities of Arrow and Supergirl. Arrow is more brooding and street - smart, while Supergirl is optimistic and has strong moral values. Have them start off with a bit of a misunderstanding, like Arrow being suspicious of Supergirl's powers at first. Then, as they face challenges together, show how they gradually come to respect and rely on each other.
To write a good character interaction, start with understanding the personalities of each character. For example, Steve Rogers' old - fashioned values would contrast with some of the more modern - thinking Agents of Shield. Let them clash over things like battle strategies at first, then gradually find common ground.
One popular trope is the team - up. Characters from Arrow and Agents of Shield joining forces to fight a common enemy. For example, Oliver Queen and Phil Coulson leading their respective teams against a new super - villain.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). It has a large collection of fanfics, and you can use the search function to specifically look for Arrow and Agents of Shield crossovers. Another option is FanFiction.net, though the quality can vary more there.
One idea could be that some of the Agents of SHIELD team get transported to Starling City where they cross paths with Arrow's team. They could team up to fight a common enemy like a meta - human terrorist group that has access to both high - tech weapons and ancient magic.
A great plot idea is a crossover centered around a new super - weapon. Maybe some ancient weapon that was lost in the Arrow - verse is found by Hydra in the Agents of Shield world. So the two teams have to work together to retrieve it before it's used for evil. Another popular one is a character - based plot. For instance, if Thea Queen discovers she has some sort of power that is related to the Inhumans in Agents of Shield. She then goes to them for help and that starts a whole series of events that brings the two groups together. Also, a plot where the two teams are forced to compete for a valuable resource, but then realize they need to work together to keep it from falling into the wrong hands can be really interesting.
First, understand the personalities of the characters from both universes. For example, if it's a crossover with 'Harry Potter', the Creeper's menacing nature would contrast with the more innocent and curious nature of the Hogwarts students. Have them react realistically to each other. The students might be initially terrified but then try to use their magic to defend themselves. Second, create a common goal. Maybe they all need to stop the Creeper from reaching a certain magical artifact. Third, use dialogue to show the differences in their worlds. The Creeper might not understand magic, and the wizards might not understand the Creeper's motives.
One idea could be that the characters from Agents of Shield are sent to the location of Until Dawn. Fitz and Simmons could be analyzing the strange occurrences in the forest, similar to how they deal with alien and supernatural events in their own show. Meanwhile, the Until Dawn characters mistake them for part of the mystery and danger. The Shield agents would then have to use their skills and technology to survive and figure out what's really going on, while also trying to convince the Until Dawn group that they're there to help.
