...Though, I've been on forums a lot and heard someone compare Chara to Christopher Robin,

and Frisk to Alice from Alice in wonderland. Likely because they are, like Alice, a lost child who falls down a hole, and wakes up in a strange place.

And that Alice is sometimes presented as a friendly force of change in Wonderland, other times a psychopathic murderer with a fantasy-like world as a toy to her. Kinda like Frisk.
