Peter's character can be developed by having him face some really tough moral dilemmas. For example, in the Infinity War chaos, he might have to choose between saving a group of civilians or going after an important Infinity Stone. This would force him to think like a true Avenger and not just a friendly neighborhood Spider - Man.
In fanfiction, their relationship could be deepened by having them share personal stories from their past. Maybe while waiting for an attack, Tony tells Peter about his early days as Iron Man and the mistakes he made, and Peter in turn shares his feelings about losing Uncle Ben. This would bring them closer.
For Tony, his character could be developed by exploring his past. Maybe he wasn't always a cook, and there was an event that made him love cooking so much. As for Colin, his development could involve him learning to be more empathetic. He's often so focused on facts that he forgets about the feelings of others. In fanfiction, we could write about how they help each other grow in these aspects.
To develop Peter further, he could be given more backstory about his childhood dreams. Maybe he wanted to be an artist but gave it up for some reason. For Lola, she could start taking self - defense classes which would show her determination to be stronger. This would also add new dimensions to their relationship as Peter might be worried about her getting hurt in the process.
Peter could be developed further by having him face a personal fear. Maybe he has a fear of losing his connection to Narnia completely. Caspian, on the other hand, could be developed by exploring his relationship with his people on a deeper level. He could be shown dealing with the everyday problems of his subjects, which makes him more relatable and also shows his growth as a king. Their characters could also be developed through their interactions with each other. They could have friendly competitions that teach them both about their own strengths and weaknesses.
One way to develop their characters is through family influence. Violet's family has a big impact on her life. If in the fanfiction, her family initially disapproves of her relationship with Tony, it could force both of them to grow. Violet might become more assertive in standing up for what she wants, and Tony could learn to respect and navigate her family's expectations. This would not only develop their individual characters but also their relationship.
To develop their characters further, they could be placed in a cross - cultural investigation. Tony, with his more worldly experience in some ways, and Spencer with his encyclopedic knowledge. They would have to learn from each other and adapt. Tony could learn more about different cultures on a deeper level from Spencer's research, and Spencer could learn how to interact with people in different cultural settings from Tony's practical experience. This would add new layers to their personalities and their relationship.
Sam's character could be developed by exploring his family background more. If he has a troubled family past, it could add depth to his character. Anya could be developed by showing her struggle with the moral implications of war. She might start to question some of the actions of their side, and Sam could be there to either support or challenge her views. This would not only develop their individual characters but also add more layers to their relationship.
One idea could be Peter trying to convince Tony to use a more risky but potentially game - changing strategy during the battle in Infinity War. For example, he might suggest using his new - found powers in a way that Tony is initially hesitant about.
Their relationship could be further developed by having them face a major crisis together. For example, if they both lose their memories but still feel a strong connection to each other. They would then have to rediscover their love and who they are as individuals. This would deepen their bond in a new and unique way.
They could be given a new shared hobby. Say they both start taking painting classes. Through this, they discover new aspects of each other's personalities. Elizabeth might be more competitive than Peter thought, and Peter might have a creative side that Elizabeth finds endearing. This new common ground would add depth to their relationship.
