Power exploration is also a theme. Since the OC is often a new addition with unique powers, the fanfiction may explore how these powers work, how they can be controlled, and how they interact with Barry's speed - related abilities. This can lead to some really cool and creative plotlines.
The relationship could be developed through shared secrets. For instance, the OC could have a secret past related to a meta - human experiment that they don't want anyone to know. Barry discovers this secret and instead of judging, he helps the OC come to terms with it. This mutual trust and understanding can deepen their relationship. Another way is if the OC has a special interest or hobby, like painting portraits of Central City's heroes. Barry could be the subject of one of these portraits, and through this, they start to have deeper conversations about their hopes and fears.
Sure. One great 'The Flash Barry OC Fanfiction' is 'Barry's New Ally'. It features an original character who teams up with Barry in an interesting way. The OC has unique powers that add a new dynamic to their adventures.
Maybe the OC is from a parallel universe where the rules of the Flash's powers are different. This could lead to a lot of exploration and conflict as Barry tries to understand and work with this new element in his world. The OC could bring new knowledge about speed force that Barry has never known before.
One idea could be that the OC has a unique power that complements Barry's speed. For example, the OC might have the ability to manipulate time on a small scale, and together they can prevent disasters that even Barry alone couldn't stop. Another plot could involve the OC being from a different dimension and Barry has to help the OC get back home while falling in love along the way. Or perhaps the OC is a scientist who discovers a new form of energy that can enhance Barry's speed even further, but there are some dangerous side - effects that they have to deal with.
The OC's pregnancy could cause a shift in the team's dynamics. They might become more protective of her, which could lead to some members taking on extra duties to keep her safe. For example, Barry might be more hesitant to engage in dangerous missions, fearing for the OC's safety and the baby's. This could potentially slow down the team's response time to threats.
First, give the OC a clear backstory. If they have powers, explain how they got them. For example, if they were in an accident like Barry, detail what kind of accident and how it differed from his. This will make their existence in the Flash's world more plausible.
Another possibility is that Barry was kidnapped himself first and then forced to kidnap Supergirl. The real kidnappers could be a group of meta - humans who want to create chaos by pitting two of the most powerful heroes against each other. Barry would be in a difficult situation, having to do something against his will, and Supergirl would initially be confused and angry at Barry until they both figure out what's really going on.
Yes, there are likely fanfictions out there with such a plot. 'The Flash' has a large and creative fanfiction community, and the idea of Barry and Caitlin having a pregnancy could be an interesting exploration of their relationship in the fan - created stories.
Another theme is emotional pain. His relationships with friends, family, and love interests can be a source of hurt. For example, a broken friendship or a lost love.
