There could potentially be such a fanfic. The Pokemon fandom is quite large and diverse, with fans creating all sorts of stories. However, this idea of Marnie being pregnant might be a bit out of the ordinary for the typical Pokemon storylines. It could be part of a more creative or alternate universe fanfic where the author is exploring different character relationships and developments.
It's possible that a fanfic like this exists, but it might be difficult to find. Fanfic writers often come up with unique and unexpected ideas. Marnie is a popular character in the Pokemon world, and some fans might be interested in exploring different aspects of her character, including more adult - like situations in a tasteful and creative way. But again, this is not a mainstream type of fanfic and would likely be among the more specialized works within the fandom.
It could explore the reactions of other characters in the Pokemon world. For example, how her friends, rivals, or family members would react to the news. It might also look at how Marnie herself copes with the physical and emotional changes of pregnancy in a world full of Pokemon battles and adventures.
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. There could be a story where she discovers new strengths within herself as she copes with the pregnancy. Maybe she starts to focus more on Pokemon that are more nurturing or protective, like Chansey, which could symbolize her own journey into motherhood.
It could be another trainer she has had a close relationship with during her Pokemon journey. Maybe someone she has teamed up with in battles or shared adventures. 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.
One popular Pokemon Marnie fanfic could be one that focuses on her journey to become a stronger trainer. It might show her training in secret spots in Galar, away from the prying eyes of other trainers. She could be facing challenges like taming a particularly difficult Pokemon that she later uses to her advantage in battles.
One common theme is Marnie's journey as a trainer. It often focuses on her growth, her battles, and how she overcomes challenges. Another theme could be her relationship with her Pokemon, showing the bond between them.
Well, there might be some in various fanfic communities. You could start by checking out popular Pokemon fanfic websites. However, the quality can vary greatly. Some might focus more on the relationship aspect between Marnie and another female character in the Pokemon world, while others could be more plot - driven with the lesbian relationship as a side element.
A possible story in this fanfic could be that they team up. Despite their differences, they realize that they can achieve more together. They could go on a journey to discover rare Pokemon or to solve a mystery in the Pokemon world. Gloria's sunny disposition might balance out Marnie's more reserved nature, creating an interesting dynamic as they travel through different regions, facing various challenges along the way.
You can try fanfiction websites like Archive of Our Own (AO3). There are a large number of Pokemon fanfics there, and you're likely to find some great ones about Marnie. Another option is FanFiction.net, which also has a wide selection of Pokemon - related fanfiction.
One possible plot could be their adventure in the Pokemon world. Maybe they team up to take on a powerful and mysterious Pokemon threat that's been causing chaos in the region. They start as acquaintances, gradually growing closer as they face challenges together and learn more about each other's Pokemon training styles.
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. For instance, if they both face a powerful, rogue Pokemon trainer, they would have to work together. This would be the start of them seeing each other in a new light.
