You can start by having them meet in a challenging situation, like rescuing a trapped Pokemon. This shared experience can be the foundation of their relationship. Then, have them gradually learn about each other's goals and dreams regarding Pokemon training.
Create conflicts that test their relationship. Maybe there's a misunderstanding about a Pokemon battle strategy or a rumor that one of them is stealing rare Pokemon. As they work through these conflicts, their relationship can grow stronger. Have them realize that they need to trust each other more and communicate better, which will make their bond in the fanfic more believable and engaging.
Show their interactions with their respective Pokemon. For example, if Kotone has a very affectionate Pokemon and Petril has a more reserved one, their different approaches can lead to interesting conversations and a deeper understanding of each other. Also, have them exchange Pokemon training tips which can bring them closer.
One idea could be that Kotone and Petril start a journey together to discover a rare and powerful Pokemon that is said to have the ability to heal the land. Along the way, they face challenges from rival trainers and Team Rocket-like organizations who also want to get their hands on the Pokemon.
Communication is key. Have them talk about their goals, dreams, and past experiences with Pokémon. For example, the trainer could share a story about their first Pokémon encounter, and the master could respond with their own similar story. Another way is through joint training sessions. As they work together to train the trainer's Pokémon, they'll learn more about each other's training styles and build respect.
In some fanfictions, it develops through friendly rivalries. They constantly compete in Pokemon contests, and with each competition, they gain more respect for each other. This respect then turns into a form of admiration, which gradually builds their relationship.
Their relationship could develop gradually. At first, they might be a bit wary of each other. But as they encounter common foes or challenges in the Pokemon world, they start to respect one another. For instance, if they both face a powerful, rogue Pokemon trainer, they would have to work together. This would be the start of them seeing each other in a new light.
One way to develop their relationship is through communication. Have them have long conversations about their different worlds. Sho can ask Arrietty about how she lives, what she eats, and how her family functions. Arrietty can be curious about Sho's school, his friends, and his hobbies. As they learn more about each other, they will start to understand each other better. Another aspect is to show their mutual respect. Sho respects Arrietty's need for privacy and safety in her tiny world, and Arrietty respects Sho's human world and the rules he has to follow. This respect will form a solid foundation for their relationship to grow.
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.
It often starts with the human showing kindness. For example, if the human finds an injured pokemon and takes it in to nurse it back to health. This initial act of care begins the bond. Then, as they spend more time together, they learn about each other's habits. The pokemon might learn human language and customs, while the human learns about the pokemon's abilities and needs.
By having them share common goals. For example, if there's a powerful artifact that both want to keep out of the wrong hands. This would force them to interact and start to understand each other's motives.
At first, N might be a bit aloof towards Touya. However, when they both get involved in helping a lost or injured Pokemon, they begin to communicate more. Touya's friendly and outgoing nature could gradually break down N's barriers. They could then start traveling together, and N would learn about Touya's dreams and goals in the Pokemon world. This shared exploration and understanding would deepen their relationship over time.
Communication is key. In a fanfic, Mewtwo could start to communicate with other Pokemon on a deeper level. Maybe it uses its psychic powers to understand their thoughts and feelings. For instance, it could communicate with a Bulbasaur who is sad because it lost its way from its trainer. Mewtwo could help it find its trainer and in the process, form a bond. Also, Mewtwo could befriend a Eevee that is constantly evolving and confused about its identity. Mewtwo, having its own identity crisis, can relate to Eevee and offer guidance, which would strengthen their relationship.
