What are some popular fanfiction themes about Ash and Serena other than romantic love?

Well, a common theme in such fanfictions is the son's special abilities or unique Pokémon. Maybe he has a Pokémon with a rare ability that sets him apart. Also, there could be themes centered around his growth in different regions. He could travel to regions neither Ash nor Serena have been to, exploring new Pokémon species and cultures. This would add an exciting element to the story as he discovers things for himself and makes a name for himself in the Pokémon world.

A common theme is the growth of their relationship. It starts with Serena having a crush on Ash and gradually winning his heart. Another theme is the support they give each other in their Pokémon training. They encourage one another to become better trainers, which also strengthens their bond of love.

One popular Ash and Serena love fanfiction could be 'A Journey of Love'. In it, they might go on adventures that strengthen their bond beyond what we see in the original series. Another could be 'Serena's True Feelings', which might focus on Serena's perspective of her love for Ash and how she overcomes various obstacles to be with him. There are also fanfictions that rewrite the entire journey with a strong focus on their relationship development from the very start.
