Start with small interactions. For example, a simple exchange of words in the hallway. Then, gradually build on it. Maybe have them work on a project together where they have to rely on each other's skills. This will create a sense of trust.
You can also develop their relationship through shared interests. If your OC is into technology, they can bond over Penny's robotic nature. They could work on small projects together, which would strengthen their bond. Also, throw in some challenges. Maybe some people at school don't trust the OC and Penny has to defend them, which would deepen their friendship.
First, establish their initial meeting. Maybe the OC saves Drago from a dangerous situation or vice versa. This creates a sense of debt or gratitude. Then, during their travels in the Bakugan world, they share their stories, their dreams, and their fears. As they do this, they start to see each other in a new light. Also, having them train together can strengthen their bond as they learn from each other's strengths and weaknesses.
To write a Todoroki OC fanfiction, you need to understand Todoroki's character well. Study his relationships with other characters in the original work, like his complex relationship with his father. Your OC can interact with Todoroki in different ways based on this. Also, don't be afraid to add your own unique twists. Maybe your OC has a quirk that reacts in an unexpected way with Todoroki's powers. And make sure to give your story a good flow, with a clear beginning, middle, and end.
One idea could be that the OC is a new student at UA High School. She has a unique quirk that Shouto finds fascinating. They get paired up for a training exercise and gradually start to understand each other better. As they face challenges together, a bond forms between them.
Start with small interactions. For example, let them exchange polite greetings at first. Then, gradually add moments of shared interests. If they both like a certain type of tea, have them discover this about each other over a casual tea - drinking session.
Start with small interactions. For example, have them meet by chance on the beach and share a simple conversation about the beauty of the ocean. This initial connection can be the foundation for a deeper relationship.
Communication is key. In the fanfiction, they could start having study sessions together. As they talk about their hero theories and strategies, they also start sharing personal stories. Shouto might open up about his relationship with his father, and Izuku could talk about her journey to become a hero despite being a girl in a somewhat sexist society. This will make them understand each other better and bring them closer.
One common theme is the idea of redemption. The female character often helps Shouto Todoroki deal with his past traumas and find a new path in life.
First, create shared experiences. For example, put them in a dangerous mission together. Second, give them common interests like a love for a certain type of jutsu or a passion for helping the village. Third, show how they support each other through difficult times, like when the OC is having trouble with her training and Shisui helps her out.
You can start by having them meet in an unexpected situation. For example, the OC could be in trouble and Kitty Pryde comes to their rescue. This creates an initial connection. Then, give them common goals. If they both want to stop a certain villain, they'll have to work together and that will bring them closer.
