After getting married, their relationship could develop in a very domestic way at first. They would share household chores related to their Pokemon, like cleaning the Pokeballs and preparing food for their Pokemon. But as time goes on, they would also grow in their individual ways. Ash might become more involved in Pokemon conservation efforts, and Serena could start teaching other trainers about the importance of a good bond with their Pokemon. Their mutual respect for each other's growth would keep their relationship strong.
Their relationship would likely grow closer. At the dance party, Ash might be a bit clumsy at first, and Serena would gently guide him, which would create some sweet and tender moments between them. They would share laughter and maybe some embarrassed blushes as they interact more intimately during the dance, deepening their bond.
They would likely support each other's hero careers. Izuku could offer Momo advice on combat based on his own experiences, while Momo could help Izuku with strategic planning using her intelligence. Their relationship would grow as they face new villains and challenges together. They might also start a family, with Izuku teaching their children about being a hero with a heart, and Momo teaching them about using their brains and powers effectively.
Their relationship could develop with them sharing more secrets. Since they are now married, Shinichi might feel more comfortable revealing some of the darker aspects of his detective work that he previously shielded Ran from. They would also support each other more deeply in their respective careers. Ran could continue her martial arts training and Shinichi would be there to cheer her on, while Ran would be Shinichi's sounding board for his cases.
In the Alola setting, their relationship could develop as they explore the islands together. They might share more personal stories while sitting on a beautiful Alola beach, watching the sunset with their Pokémon by their side. This could bring them closer emotionally.
During time travel, their relationship could take a new turn. They might discover new sides of each other. If they travel to a time where Pokémon battles were different, Serena could see Ash's adaptability and grow more attracted to him. On the other hand, Ash could see Serena's quick thinking in handling the unfamiliar situations in the past or future, which would make him appreciate her more. It could be a journey of mutual discovery and growing affection.
At first, Ash and Grace might be a bit hesitant around each other. But as they encounter different Pokemon and face various challenges like difficult terrains or strong wild Pokemon, they would start to communicate better. They would learn about each other's dreams and goals regarding Pokemon. This understanding would deepen their relationship, and they could end up being like family, always looking out for one another.
At first, Zoroark might see Ash as just another human who could potentially be a threat. However, if Ash saves Zoroark from a hunter's trap, that would be a turning point. Zoroark would then be curious about Ash. As they spend more time together, Zoroark would start to imitate Ash's behaviors in a playful way, which shows that it's getting closer to him. Eventually, they would develop a deep friendship where Zoroark would be very protective of Ash and Ash would consider Zoroark as one of his most special Pokemon friends.
Their relationship might start off with a lot of pent - up emotions. Ash could be a bit distant at first due to his war experiences, but Serena's love and care would gradually draw him out. Eventually, they would become closer as they share their feelings and experiences during the time they were apart.
Their relationship could develop further through shared adventures. For example, if they team up to rescue a group of endangered Pokemon, they would have to rely on each other's strengths and trust each other completely. This would deepen their bond.
Their relationship develops as they face challenges together. In Kanto, every new Pokemon they encounter, every Gym battle Ash participates in, Serena is there. She cheers him on, and through this shared experience, they grow closer. For example, when Ash loses a battle, Serena is there to comfort him, and this makes their bond stronger.
