One great Ash and Serena fanfiction in the Pokemon Sun and Moon setting is 'A New Adventure Together'. It has a really engaging plot where Ash and Serena meet up again in the Alola region and go on a journey to discover new Pokemon. The author does a wonderful job of capturing their characters and the unique charm of the Alola region.
There's also a fanfic called 'Serena's Alola Dream'. In this story, Serena decides to visit Alola to see Ash and ends up getting involved in his island trials. It's a cute story that focuses a lot on their relationship development. It shows how Serena adapts to the new environment and how her presence affects Ash's journey in a positive way.
The best aspect is seeing their relationship grow. In the Pokemon Sun and Moon setting, they get to experience new things together. For example, Serena can learn about the unique Alola Pokemon and Ash can show her around. Their interactions are really sweet, like when Ash introduces Serena to his new Alola friends. It adds a new dimension to their relationship.
A fanfiction could focus on Ash Greninja's unique form and abilities. For example, it could tell a story where Ash has to rely on Greninja's special skills to overcome a powerful, mysterious Pokemon in the Alola region. This would show the significance of their partnership in the context of Pokemon Sun and Moon.
Ash is a great character to pair Serena with. Their history from previous adventures adds depth to the story. They could have new adventures together in Alola, with Ash showing Serena the ropes of the Alolan Pokemon world and Serena sharing her own unique skills. Another good option is Lillie. Serena and Lillie could bond over their love for Pokemon. They could help each other grow, like Serena teaching Lillie more about Pokemon battles and Lillie introducing Serena to the unique Alolan Pokemon.
One possible fanfiction could be about Ash and Lillie's adventure in the Alola region. Maybe they team up to face a powerful new Pokemon that has been causing trouble. They use their combined skills and the unique bond they've developed throughout their journey in Pokemon Sun and Moon.
Well, one possible plot could be Serena returning to Alola to participate in a grand Pokemon tournament. She might bring along some new Pokemon she's trained in her time away. Maybe she teams up with the main character from Sun and Moon to take on the toughest opponents.
A great storyline could be Serena using her skills from her previous Pokemon training in new and unexpected ways in the Alola region. Maybe she uses her knowledge of battling to help train local Pokemon that are having trouble evolving or learning new moves. This could also lead to her becoming a sort of mentor to younger trainers in Alola, passing on her wisdom and experiences from her travels in other regions.
A possible fanfiction plot could be that Ash, Serena, and May are invited to a mysterious island full of unknown Pokemon. They have to work together to survive and discover the secrets of the island. Ash's leadership, Serena's ability to communicate with Pokemon, and May's quick decision - making skills would be crucial.
In some fanfictions, Ash Greninja's moment of saving Ash from a dangerous fall during a battle in the Alola region is really cool. It shows their loyalty and quick reflexes.
In many such fanfictions, the plot might involve Ash's friends suddenly turning against him due to some false accusations or misunderstandings. For example, they could believe that Ash has been secretly working with an enemy group, which leads to his betrayal.
In the world of Ash and Serena Sun and Moon fanfictions, 'Alola's Destiny' stands out. This fanfiction dives deep into how Ash and Serena's paths cross again in the Alola region. It not only shows their individual growth but also how their relationship evolves. The detailed descriptions of the Alola region and its Pokémon add to the charm. 'Serena's Sun and Ash's Moon' is another interesting one. It plays with the idea of their different experiences in the Alola region, Serena being more in tune with the sun - related aspects and Ash with the moon - related ones, and how they come together through it all.
