The key plot points might start with Bruce Wayne noticing Barry Allen's potential. He could see that Barry has a good heart and a sharp mind despite his difficult circumstances. So, Bruce decides to adopt him. Then, as Barry grows up in Wayne Manor, he starts to show signs of his speed powers. This could lead to a series of events where they have to keep Barry's powers a secret from the outside world. And later, perhaps they work together to fight crime in Gotham, with Barry using his speed in ways that complement Bruce's detective skills and combat abilities.
Well, one key plot point could be how Bruce Wayne first comes to the decision to adopt Barry Allen. Maybe Barry is in a tough situation, like being an orphan or in danger, and Bruce's sense of justice and his own orphan past drive him to take Barry in. Another plot point could be how Barry adjusts to living with Bruce. He might struggle with Bruce's strict rules and training regimens at first, but gradually come to understand their purpose. Also, there could be a plot point where Barry discovers his super - speed abilities while under Bruce's care, and Bruce has to figure out how to help Barry control and use his powers for good.
The adoption would have a profound impact on the DC Universe. Firstly, in terms of storylines, there would be a whole new set of arcs centered around Bruce and Barry's relationship. For example, how Bruce helps Barry master his powers while also dealing with his own issues. Secondly, it could change the way the superhero community views family. If Bruce can successfully adopt and mentor Barry, it might inspire other heroes to take in proteges. And finally, it could affect the balance of power in the universe. With Barry having Bruce's support, he could become a more dominant force in battles, which might force villains to rethink their strategies and alliances.
One idea is that Barry discovers a time - related threat that has the potential to erase Bruce Wayne's past, which in turn would change the present Gotham City. They have to race against time (literally for Barry) to stop this threat. Another could be that a meta - human is stealing high - tech equipment from Wayne Enterprises and using it for evil purposes. Barry and Bruce work together to track down this meta - human and retrieve the stolen tech.
Perhaps they start off as rivals at first. Bruce might be a bit suspicious of Barry's powers and his more light - hearted approach. But as they get to know each other better, they realize they can learn a great deal from one another. Barry could teach Bruce to loosen up a bit, while Bruce could show Barry how to be more strategic in his superhero work.
In this fanfiction, perhaps Danny Phantom's identity gets exposed in his hometown in a way that makes it unsafe for him. Bruce Wayne, who is always on the lookout for those in need, decides to adopt Danny. Danny brings his unique perspective and powers into Bruce's world. He might start training with Bruce and the Bat - family, all while trying to keep his ghost - related problems from spilling over into Gotham's normal world.
In this fanfiction, Bruce might see a lot of himself in Harry. Harry has endured great loss at a young age, just like Bruce. So, Bruce Wayne adopts Harry Potter. Harry could then grow up with access to both the wizarding world and Batman's resources. He could use his invisibility cloak in new and creative ways to help Batman fight crime in Gotham. And perhaps he'd introduce some magical elements to the Batcave.
One interesting plot point is the clash of cultures. Bruce Wayne comes from a world of high - tech and street - level crime - fighting in Gotham, while Harry Potter is from a world of magic. How they bridge this gap, like Bruce trying to understand spells or Harry dealing with non - magical technology, is really engaging.
One possible plot is that Spiderman gets involved in a case that is related to Gotham's underworld. Bruce, seeing Spiderman's potential and also his naivete in some aspects, decides to adopt him and guide him through the complex world of super - heroics. Along the way, they face common enemies and learn from each other.
Well, one key plot point could be how the fem Kyuubi changes Naruto's life. Maybe she uses her unique powers to protect him from his early childhood bullies in the village. Also, she might teach him some secret jutsus that are only known to the Kyuubi, which would make Naruto a much stronger ninja at a younger age. Another aspect could be how their relationship affects Naruto's relationships with his friends like Sasuke and Sakura. Since the Kyuubi is now a female and has adopted Naruto, it might create some jealousy or confusion among his friends at first, but eventually they come to understand the positive impact she has on Naruto.
One possible plot could be Barry Allen using his super speed to solve a complex mystery in Central City. He might discover a new villain who has the ability to manipulate time, and he has to race against the clock (literally) to stop the villain from changing the timeline in a disastrous way.
Well, in a Barry Allen creates Gideon fanfic, the plot might start with Barry realizing the need for a more advanced technological support system. So, he begins to research and develop Gideon. As he does this, he discovers some new scientific principles that he has to master. Maybe he has to collaborate with some other brilliant minds in the DC universe, like Cisco Ramon. And during the creation, Gideon starts to develop its own personality earlier than expected, which causes some unforeseen problems for Barry. For example, Gideon might start to question Barry's motives or methods, leading to an internal conflict within the fanfic's storyline.
