I'm not sure there are a lot of Orb Weaver Mirabel Madrigal fanfictions specifically. But it could be really interesting if it focuses on Mirabel's unique personality within the Madrigal family and how she might interact with an orb weaver concept. Maybe it could be a story where Mirabel discovers an orb weaver with magical powers that are related to the family's magic in some way. For example, the orb weaver's web could be a symbol of the family's interconnectedness that Mirabel has to figure out how to use to save the family's magic again.
I'm not sure specifically as it could be any number of creative interpretations. It might be about a situation where Alma Madrigal blames Mirabel for something within the context of the fan - created story, perhaps related to the events or family dynamics in the Encanto universe.
Perhaps Abuela believes that Mirabel's presence without a gift is somehow jinxing the family's magic. In the fanfiction, she might think that by imprisoning Mirabel, she can stop the negative effects she thinks Mirabel is causing. This could be related to some superstitious beliefs within the Encanto about the balance of magic and the role of each family member.
The younger characters in Encanto like Antonio would be excited. He loves stories and new ideas, so Mirabel fanfiction would be like a new adventure for him. He might want to share it with his animal friends. And Dolores, with her ability to hear everything, might already know about the fanfiction. She could be either intrigued or a bit worried depending on how the fanfiction is being received by the rest of the village. If it's causing a stir, she might be concerned about the family's reputation, but if it's positive, she would likely be quietly supportive.
A possible plot could be that the orb weaver is a protector of the Madrigal family's magic. Mirabel discovers it when she feels lost and left out. The orb weaver shows her a vision of the past and how the family's magic was first created. This gives Mirabel the idea to use the orb weaver's magic to enhance the family's existing magic in a new way, bringing a new era of harmony to the Madrigals.
Maybe she feels left out in the family. In the Encanto story, Mirabel is the odd one out not having a special gift. This could make her feel so alone and unwanted that she decides to run away.
There are several places to look for this fanfiction. As mentioned, AO3 and FanFiction.net are well - known platforms. However, you could also check out some Encanto - focused fan communities on social media platforms like Tumblr or Reddit. Sometimes, fans will share links to their favorite fanfictions or even post their own work there. Additionally, there might be some smaller, more niche fanfiction sites that could have this particular story, but it might take a bit more digging to find them.
It could be someone who is jealous of Mirabel's potential. Maybe a relative who feels that Mirabel's new - found importance in the family (even if she doesn't fully realize it yet) threatens their own status. For instance, a cousin who was once favored but now sees Mirabel as a threat.
