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.
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 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.
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.
Edward would be a likely character. As part of the Cullen family, he would have an interest in Alice's situation. He might offer his support or advice based on his own experiences in the Twilight world.
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.
Hal could be a very likely character. Since he was Alice's husband in the show, he could play a big role in the fanfiction. He might be the father, or he could be dealing with the news in different ways, like being supportive or having doubts. Another character could be Betty. As Alice's daughter, she would surely be affected by her mother's pregnancy. She could be helping Alice out or having her own emotional turmoil because of it.
There could be a human friend of Alice as well. This friend might be someone who is also trying to survive in the world filled with the supernatural elements from 'Alice and Blood'. Their friendship could be a source of support and also add some emotional depth to the story as they face various challenges together.
There could be other characters who are trying to stop Chara from eating the human. Maybe a group of friends or family of the human, or some sort of protectors in the world of the fanfic. They would play a crucial role in trying to prevent the dark act from happening.
Since it's named 'alice or alice visual novel', it's likely that the main characters are named Alice. There might be different versions or incarnations of Alice.
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.
