Another theme is her relationship with her Pokemon. It's about how she bonds with them, takes care of them, and how they support her in battles. Rivalry is also a common theme, especially her rivalry with other trainers in the Galar region.
The plot might involve Marnie finding out she's pregnant and having to make some tough decisions. She could be worried about how it will affect her future as a Pokemon trainer.

This character would need to be someone who has a connection with Marnie on a deeper level, and they could have had a romantic moment that led to the pregnancy.
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.
