Well, perhaps the shrinking is a result of some magic gone wrong. As she shrinks, she loses her confidence at first. But then, she realizes that her new small size gives her an advantage to explore hidden corners of Wonderland. She could find secret passages or solve mysteries that were impossible for her at her normal size.
The Caterpillar could be the main antagonist. He has always been a bit of an enigma in Wonderland. Maybe as Alice shrinks, he sees her as a threat to his control over the small part of Wonderland he rules and tries to stop her from exploring further.
Well, in this type of fanfic, the slow shrinks can enhance the exploration of the strange and illogical world of Wonderland. As Alice shrinks slowly, she may have more time to interact with the various characters she encounters. For example, her conversations with the Cheshire Cat or the Mad Hatter could be more in - depth and revealing, as she is changing size gradually and they might react differently to her continuous shrinking.
In the fanfic, the act of Alice eating the apple and shrinking could lead to a self - discovery journey. As she gets smaller, she realizes things she never noticed before. She might also develop new relationships with the small beings she meets. The story could explore themes like the perception of size, and how changing one's physical state can also change one's perspective.
The growth in an 'alice in wonderland growth fanfic' might be physical as well. Imagine Alice starts to have some control over her size changes. Instead of being at the mercy of the magic food and drink, she learns to manipulate it for her own purposes. This newfound control could lead to her exploring parts of Wonderland that were previously inaccessible due to her size limitations.
Definitely Alice, as she is at the core of any 'Alice in Wonderland' - based story. The Caterpillar could be another important character in this kind of fanfic. The Caterpillar, which is already a symbol of transformation in the original story, could have a more complex role as it observes Alice's slow shrinking. Maybe it could offer some sort of guidance or be a source of knowledge for Alice as she deals with her changing size in this new version of the story.
One possible plot idea could be that the OC, a newcomer to Wonderland, meets Absalom. Absalom could initially be suspicious of the OC but as they journey through Wonderland together, they start to form a bond. For example, they might face the challenges of the Queen of Hearts' wrath side by side and in the process, discover new things about Wonderland and each other.
In a dark Alice in Wonderland story, perhaps Alice falls into a nightmarish Wonderland. The Cheshire Cat could be a menacing figure, leading her astray instead of being a curious guide. The Queen of Hearts might be even more blood - thirsty, with executions being a common and truly gruesome sight. And the Mad Hatter could be a deranged lunatic who tries to harm Alice rather than just having a mad tea party with her.
Well, there could be a little mouse. Since Alice is shrunk, the mouse could be her guide in this new, small world. It might show her where to find food or shelter.
One idea could be that Alice returns to Wonderland as an adult and has to deal with new, more complex riddles and challenges that are related to the grown - up world she now knows. For example, the Queen of Hearts might be having a 'tax collection' problem in her kingdom and Alice has to use her real - world knowledge of economics to solve it.
One interesting plot twist could be that the Red Queen is actually being controlled by an unseen force. It adds a new layer of mystery to her actions.
