That title always sparks a little confusion for me because 'Wicked Wonderland' shows up in a few places — a song, indie comics, and a handful of fanfics — so I usually ask which one someone means. Still, when people ask about the main characters, they tend to mean the dark, Alice-inspired retelling version, so here’s the lineup I usually talk about when I’m describing that universe.
The protagonist (often an Alice analogue): a curious, stubborn young woman or teen who stumbles into the twisted realm and has to outwit its rules. She’s sharp, morally flexible at times, and grows into someone who questions authority rather than just obeying it. The Queen (or Red/Black Queen): the obvious antagonist, theatrical and cruel but with a tragic past that explains her tyranny. I love when creators give her a sympathetic thread so she’s not just a cartoon villain.
The Mad Hatter type: an unpredictable ally, sometimes more of an antihero, brilliant in small-scale chaos and brutally honest. The Cheshire-ish trickster: a slippery, grinning guide who may help or betray you depending on their whim. The White Rabbit analogue: the initial catalyst who drags the protagonist into the world, often anxious and secretive. Boss monsters or court enforcers (Jabberwock-style) round out the cast — imposing, symbolic, and usually the final gatekeepers. I’ve sketched cosplay ideas for several of these characters after late-night readings, so if you want specifics for a particular version of 'Wicked Wonderland' I can dig deeper into that incarnation.
