I'm not sure if there is such specific fanfiction readily available. You could try searching on popular fanfiction websites like Archive of Our Own or FanFiction.net.
One possible plot could be that Audrey has a long - standing rivalry with Mal. Mal's pregnancy is unexpected and Audrey sees it as Mal getting ahead in life. Maybe Audrey has her own insecurities and dreams that she feels are being overshadowed by Mal's pregnancy. This jealousy could lead to Audrey trying to undermine Mal during her pregnancy, or she might try to win over the affection of the people around Mal out of spite and envy.
No, it's not acceptable. Bullying in any form, whether in real life or in fanfiction, is wrong. Writing about bullying a pregnant person is especially cruel as pregnancy is a vulnerable time. Fanfiction should promote positive values and healthy relationships rather than negative and harmful behaviors like bullying.
In general, fanfiction often delves into various scenarios, but bullying in any form can be a sensitive topic. If the story aims to show the growth and overcoming of such negative situations, it could work. But it has to be written carefully so as not to glorify the bullying behavior. It should rather focus on the pregnant Mal's strength and how she deals with the bullies, like Chad and Audrey.
One way is to set clear guidelines in the fanfiction community. If the platform has rules against bullying - themed stories, especially ones targeting vulnerable characters like a pregnant one, it can deter creators. Also, promoting positive and inclusive themes can shift the focus away from such negative ideas.
One of the main themes is redemption. Audrey might have made some mistakes, and fanfictions often explore her journey to redeem herself in Mal's eyes and in the eyes of Auradon. Also, the theme of self - discovery is quite common. As they interact with each other, both Mal and Audrey learn more about themselves. For example, Mal might discover a more forgiving side of herself, and Audrey might find new strength in facing her past actions. In addition, the theme of acceptance is also there. They learn to accept each other's differences and past actions which helps in building a new relationship between them.
A common theme is acceptance. Since they start in a situation where they may not be aware of their sisterhood, accepting each other is a big part. Another is family secrets, as the discovery of being sisters often involves uncovering some hidden family matters.
One common theme is friendship. Since they have a complex relationship in the original story, fanfictions often explore how they can overcome their differences and become friends. Another theme is redemption. For example, Audrey might be given a chance to redeem herself after her actions in the original story. And of course, there's the theme of love triangles, which can add a lot of drama to the stories.
Well, one possible plot could be that Mal, despite being pregnant and bullied by Chad and Audrey, finds strength within herself. She could start by ignoring their taunts and focus on taking care of herself and her unborn child. Eventually, her kindness and strength could win over other characters who then come to her defense, making Chad and Audrey realize their wrongdoings.
There is a fanfiction that I really like which is titled 'Audrey's Redemption in Mal's Eyes'. It starts with Mal being very skeptical of Audrey after all the things that happened. But as the story progresses, they both grow and change. Mal realizes that Audrey is more than her past mistakes. It's a great read as it delves deep into their characters and how they can evolve in relation to each other. You can also look for fanfiction collections on Tumblr that are dedicated to Mal and Audrey. These often have a variety of different takes on their relationship.
