Ben's relationship with his friends in the context of the Dark Elf fanfic could also be developed. His friends might be initially scared of the Dark Elf. Ben has to convince them that they can find a way to deal with it. This could strengthen their bond as they face this new threat together.
For their relationships, it could be that Snape initially resents having to work with Harry in any way related to Flamel. However, as they encounter challenges together, such as dark magic threats trying to stop them from reaching Flamel's secrets, Snape realizes that Harry is more than just James Potter's son. Harry, on the other hand, begins to understand Snape's past and the reasons for his coldness. Flamel, with his long life experience, could share stories that make Snape and Harry reflect on their own lives and relationships.
Ben 110 can be developed by giving him new challenges related to the Highbreed. For example, he could face a Highbreed villain who has a power that nullifies Ben's alien forms. This would force him to rely on his human intelligence and resourcefulness. He could also develop his character by learning about the Highbreed's language and communication methods, which would show his adaptability.
Buffy and Giles' relationship could be strained as Giles becomes too obsessed with studying the Hellmouth broth and its potential effects. Meanwhile, a character with dreadlocks could come between them, causing more tension. Maybe the dreadlocks character has a different view on the broth and tries to convince Buffy to side with them against Giles.
A great way to develop their relationship further is to introduce a third party, like an alien who has a special connection to Ben's powers. This alien could be jealous of Julie or try to drive a wedge between them. But in the end, Ben and Julie's love and trust for each other overcomes the obstacle. Also, they could go on a long journey across different planets to find a cure for an illness that affects Julie, and during this journey, they share many intimate moments and really understand each other on a whole new level.
Character relationships can also be developed through secrets. One character might discover a secret about another character's past or family. This could lead to a deeper connection. For example, a character might find out that another character is the heir to a powerful avatar family but is trying to hide it because they don't want the pressure. The first character could then choose to keep the secret and in the process, they become closer friends.
Maybe the Dark Elf is actually a misunderstood being. In the fanfic, Ben could discover that the Dark Elf was forced into doing bad things because of some other powerful and evil force. So, Ben tries to help the Dark Elf break free from this control and they end up becoming allies.
In a fanfic, Ichigo and Rukia's relationship could be developed by introducing emotional arcs. Maybe Rukia has a secret she's been keeping from Ichigo, and when it's revealed, it causes a rift between them. But through their shared love for their friends and the Soul Society, they eventually overcome it. Aizen could be the catalyst for this. His actions could force Rukia to reveal her secret. Meanwhile, Aizen's relationship with them could be developed by showing his envy or admiration for their relationship. He could try to break them apart because he sees their bond as a threat to his own plans, or he could be secretly longing for a relationship like theirs, which adds a new layer of complexity to his character.
The relationships can be developed through shared experiences. For example, if they go on a journey together, facing perils like dangerous beasts or difficult terrains. They would have to rely on each other for survival, which would gradually build trust. Wendy might use her dragon slayer magic to protect Chelia and Yuri from a fire - breathing monster, and in return, Chelia could use her plant - based magic to heal Wendy if she gets injured. Yuri, with her unique skills, could be the one to find a way out of a maze they get trapped in. These experiences would bring them closer.
By having them face a common enemy. When they fight side by side against a powerful foe, they can learn to trust each other more and understand each other's fighting styles better.
The plot can start with the event that causes the shrinking, like a malfunctioning magic portal. Then, the shrunken elf could face challenges like being chased by a curious cat in Santa's house. Next, he might find allies among other small creatures. Finally, he discovers a way to reverse the shrinking.
