One common theme is the exploration of power. Since Arceus is extremely powerful and Mew has unique abilities, many fanfics will delve into how they use or control their powers. Another theme is friendship or partnership. They are two very important Pokémon in the lore, so their relationship, whether it's a new - found friendship or an age - old bond, is often explored.
The concept of creation is also quite common. Given that Arceus is often associated with the creation of the Pokémon world and Mew is the ancestor, fanfics might explore how they were involved in the creation process. For example, they could be working together to create new Pokémon species or to shape the different regions. Additionally, the theme of balance in the Pokémon world, with Arceus and Mew playing key roles in maintaining it, is frequently seen.
A less common but still present theme is the idea of sacrifice. In some 'arceus and mew fanfic', one of them may have to sacrifice something for the greater good of the Pokémon world. It could be their power, their freedom, or even their existence. This theme adds a layer of drama and depth to the stories and makes them more engaging for the readers.
