She is free-spirited, open-minded and shows concern and compassion to all around her. The Unicorn has a personality that develops throughout the progression of the story. She initially had no clothing, but later wore a light purple dress and matching shoes while staying at Haggard's castle. As the movie progress and the more human she becomes, the symbol soon fades away. She retains her violet eyes and the lavender star symbol on her forehead. Her hair is white and goes all the way down her back. In the movie, Amalthea is similar in appearance to her book counterpart. She could make no movement that wasn't beautiful, even when stumbling around. But also illuminated, like the sea by strange glimmering creatures that never rise to the surface. They are farther apart than most, deeper set, and dark as the deep sea. She shone through Schmendrick's cloak no matter how much it wrapped around, like the sun through leaves. On her forehead is a small, raised mark that was darker than the rest of her skin, the shape of it resembled a starburst like in her unicorn form.

It hurt him and warmed him at the same time. Her face is the most beautiful that Schmendrick had ever seen. The hair's length reaches the small of her back. In the book, Amalthea is a young girl, her skin the color of snow by moonlight, she has fine tangled hair that is white as a waterfall. The main differences are that her hair is a very light blue, her horn is a periwinkle color and she has a lavender star on her head where her horn is. The movie version of the Unicorn is very similar to the book's description, she is very elegant and is a stark white color. Her movement is described as a shadow on the sea. Her legs are thin with feathers of white hair at the ankles, and her long horn shines with a seashell light even in the dark. Her mane reaches the middle of her back, it has a texture that was as soft as dandelion fluff, and as fine as cirrus. Her neck is long and slender, making her head appear smaller than it really is. With clear and unwearied eyes, even though she is very old. In the book, the Unicorn is the color of snow falling on a moonlit night.
