The fanfic could be set in a post - apocalyptic world. Scott, Alex, Gabriel and the OC as the fourth brother are trying to survive. They have to find food, shelter and avoid the various gangs that roam the land. Scott is the one who often scouts for new areas, Alex figures out how to make the best use of the resources they find, Gabriel is in charge of security, and the OC as the fourth brother has a special ability to sense danger from afar. Their bond as brothers helps them stay alive in this harsh world.
Perhaps in the fanfic, they are all students at a prestigious academy. There are different houses at the academy and they are from the same house. They enter a competition against the other houses. Scott is determined to win for their house's pride, Alex studies hard to master the academic aspects of the competition, Gabriel trains physically for the sports part of it, and the OC as the fourth brother has an unexpected talent that gives their house an advantage. Along the way, they deal with rivalries, make new friends, and of course, strengthen their brotherly relationship.
A simple plot could be that they are all part of a guild in a fantasy world. The guild is facing a rival guild that is causing trouble. Scott, Alex, Gabriel and the OC as the fourth brother have to work together to defend their guild's honor. They train hard, with Scott being the most enthusiastic about combat training, Alex focusing on the strategic aspects, Gabriel on physical strength improvement, and the OC using his unique skills (maybe some form of magic) to give them an edge.
In this fanfic, the relationship between Scott, Alex, Gabriel and the OC as the fourth brother could be explored in depth. It might start with the OC being an outsider, not fully accepted by the others at first. But as time goes on, through shared experiences like defending their village from invaders, they come to realize his value and he becomes an integral part of their brotherly bond. Their individual personalities would also play a role in how they interact. For example, Scott's impulsiveness might sometimes clash with Alex's more cautious nature, while Gabriel tries to keep the peace, and the OC brings a fresh perspective to their group dynamics.
There might be a fanfic where the relationships between them are explored. For example, the OC's older half - brother could have a conflict with Scott at first because they have different views on how to handle a certain situation. But as the story progresses, they learn to understand each other. Alex and Gabriel could be the mediators in this situation, trying to keep the peace between the two.
When writing, focus on the relationships between the characters. For instance, show how the OC's older half - brother interacts with Scott. Are they friends or rivals? You can also include some dialogue to make the story more engaging. For example, Gabriel could say something funny to break the ice when there is tension between the characters. Also, describe the settings vividly so that the readers can picture the story in their minds.
Scott could be the leader - like figure among them, using his optic blasts to protect his brothers and the X - Men. Alex, with his powerful energy blasts, might be the more impulsive one who often rushes into danger. Their older brother could be the strategist, coming up with plans to outwit the enemies.
In the fanfic, their older brother might be a bit of a rebel. He could have left the X - Men for a while due to some ideological differences. But then, when Scott and Alex find themselves in a really tough situation, he comes back to help. He brings with him some new fighting techniques he learned during his time away, and together they form a stronger team.
It could include their training sessions at the X - Men school. They would learn from the experienced mutants like Professor X and Wolverine. Their powers would be refined, and they'd form bonds with other students.
One possible fanfic could be about Scott and Alex's journey in the X - Men world. Maybe they discover new powers together. For example, Scott's optic blasts could combine with Alex's energy manipulation in a unique way during a battle against a powerful mutant enemy.
One possible plot could be that the OC is a new mutant who arrives at the X - Men school. Jean Grey senses a powerful and unique energy within the OC. Scott is initially cautious but as they all train together, the OC starts to develop feelings for both Jean and Scott. Meanwhile, a common enemy emerges that forces them to work closely, and during this time, a complex love triangle forms as Jean and Scott also find themselves drawn to the OC in different ways.
One possible plot could be that Gabriel, with her lazy and mischievous nature, gets transported to the Baruto universe. She then meets the young ninja students. At first, they are confused by her strange appearance and behavior. But gradually, Gabriel starts to teach them some of her own 'unique' ways of getting things done, which are very different from the ninja training they are used to. This causes both chaos and new learning experiences in the Baruto world.
Well, it could involve Gabriel facing all kinds of supernatural challenges while being pregnant. Maybe other supernatural beings are either trying to protect or harm him. There could also be a search for a way to ensure a safe delivery in the supernatural world.
