|Danger is my middle name… well, actually, it's Xylophone.|
|—Madeline Hatter in "Dragon Games"|
Madeline Hatter, or referred to as, Maddie by her friends (full name Madeline Xylophone Hatter), is a 2013-introduced and all-around character. She is part of Alice's Adventures in Wonderland as the next Mad Hatter, and she is a student at Ever After High. In the destiny conflict, she is on the Rebel side out of a general belief that people should be free to choose, though she herself is eager to follow in her father's footsteps. As all Wonderlandians, she has access to Wonderlandian magic, although it is more accurate to say that Wonderlandian magic has access to her, because she doesn't have control over her powers. Per their escape to Ever After, all the escaped Wonderlandians transferred from Wonderland High to Ever After High. Her middle name is revealed to be Xylophone by her comment in "Dragon Games". She is daughter of the Mad Hatter.
In English, Madeline Hatter is voiced by Cindy Robinson.
Madeline is bright, energetic, and extremely friendly. Also very optimistic. Generally, she interprets things more positive than they are, the one exception being when people are explicitly arguing. Madeline is also extremely fond of tea and keeps an entire tea set, including her tea buddy and pet Earl Grey, in her hat to be ready for tea time literally wherever she goes. The Wonderlandian magic which manifests in her is how she can do impossible things if she doesn't know they are impossible, she sometimes has visions of other times and other places, she can read people's thoughts as well as being able to hear the narrators, something which her peers don't believe her on. She also sometimes speaks in Riddlish, the Wonderlandian language of riddles without realizing that she is not speaking Ever After English, that is. As Ever After is a completely different kingdom and country from the country of Wonderland, she sometimes struggles to communicate with others, specifically Ever Afterlings, albeit her diary is completely understandable where she explains the Riddlish language. In her diary, she speaks a riddle about "change", what "jingles in your pocket" but "is never the same" about what people in Ever After of the Fairytale World are exactly afraid of (specifically about the rules of "destiny" and "fate"), and even translates Kitty Cheshire's Riddlish to us. Underneath her giddy, happy, optimistic, positive, and bubbly personality, she also hides a very intelligent person who can be quite serious about matters when she wants to be.
Her "Magic Touch", is that she can pull out an item from her hat of many things which is the hat she always carry, while her tea set is in kept her teacup hat and some tea items are in her pockets.
Madeline is a girl around Raven Queen's age, but she is much more petite or shorter in statute, as so as Apple White, who is shorter than Raven. She is described to be one of the shortest students in Unfairest of Them All. Although, this difference in height with Ever Afterlings is quite Wonderlandians. Her hair is curly and wavy, and comes in three colors: dark turquoise, mint green, and dark purple or violet. She has bright blue-teal eyes and light skin. She is also shorter than most of her classmates, and has a signature baby face. Her main fashion accessory theme is tea, which include a teacup hat; most of her outfits incorporate tea set-inspired details. As the future Mad Hatter, Maddie also rarely goes around without a hat. In addition to her hair's colors, her clothes of choice feature yellow, black, and blue, which is called mad-tastic style combined with a vast array of non-synchronized patterns, her average look is a busy one, befitting her energetic personality. Her civilian look is a magenta puffy-sleeved layered dress with a blue bow around the waist. White leggings cover her legs. They are blue-spotted. She wears white-cream shoes with gold teapot-handle-resembling wedges or heels at the bottom of them.
After school, Maddie manages her father's Tea Shoppe in Book End. She finds running the business somewhat easy, as her friends from school normally visit. That, as well as her love for Wonderland madness and tea. Outside of her working hours, Madeline finds enjoyment in hosting tea parties with her friends wherever.

Though not necessarily friends, Madeline is on decent terms with the narrators, who will stop fighting if she tells them to. Madeline is one of the two students that are aware of their existence, being uniquely able to hear and talk to them, the other being Kitty Cheshire. Madeline also is in close terms with Brooke Page (daughter of the narrators) who often tells Madeline things to push the story in the right direction. In the books of the first series, she also talks with the narrator of that series, who would rather tell the story at most times than talk to Madeline Hatter.
Madeline is not currently romantically involved with anyone, but she keeps an eye open for a boy who's just as mad for tea as she is.
Madeline has the ability to store endless amounts of things inside her hat, as-well as communicate with people in different dimensions.
