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.
Often, there are themes related to the changes in the Pokemon's behavior during pregnancy. Some fanfics might show how the pregnant Pokemon becomes more docile or more protective of its surroundings. There could also be themes about how other Pokemon in the area react to the pregnant one, whether they show support or become a bit more cautious. These themes help to build a more vivid and engaging story within the world of Pokemon fanfic.
It's not common. The Pokemon franchise mainly revolves around things like collecting Pokemon, training them for battles, and exploring the Pokemon world. A human being pregnant with a Pokemon is something that really goes against the traditional ideas in the Pokemon series. However, in the world of fanfic, some writers might use this concept to create very creative and thought - provoking stories that can attract readers who are looking for something different and edgy.
No. Fanfics with such tags often contain content that goes against the family - friendly nature of the Pokemon franchise. The 'pregnant' aspect combined with 'lemon' (which is a euphemism for adult content in fanfic terms) makes it inappropriate for a wide - ranging audience.
I'm not sure if there are specific 'Pokemon Dawn pregnant' fanfics that are considered appropriate. Fanfics can vary greatly in nature. Some might be found on fanfic platforms, but you need to be cautious as many might not adhere to the family - friendly or positive - themed standards of the Pokemon franchise.
There could be. The Pokemon fandom is quite large and diverse. Fanfic writers love to create unique storylines for their favorite characters. Ash and Serena are popular characters, so it's not surprising that someone might write a fanfic about them having a family. But these types of fanfics may not be endorsed by the official Pokemon creators.
A theme that frequently shows up is the connection between the pregnant legendary pokemon and other characters. For example, a trainer might form a special bond with the pokemon during this time. Also, the idea of new life bringing hope or change to the pokemon world is a common thread. It could be that the birth of the new legendary pokemon is prophesied to bring some sort of positive transformation.
One possible plot could be Serena discovers she's pregnant during her Pokemon journey. This could bring about a lot of changes in her goals and how she interacts with her Pokemon. Maybe she has to take a break from her usual adventures to take care of herself and the upcoming baby, and her Pokemon become more protective of her.
Personally, I think it's a bit of a strange concept for a Pokemon fanfic. The Pokemon world is more about battles, friendships, and exploration. While fanfics can be creative, this idea of 'pokemon pregnant' might be a bit too far - fetched and could potentially be misconstrued. It would need to be very carefully crafted to be acceptable.
