Amy is a pink-furred anthropomorphic hedgehog with bright green eyes and peach skin covering her muzzle, inner ears and arms. She has a small black nose, triangular ears on top of her head, and no back spines. She also has two medium-length eyelashes on each side of her eyes. Additionally, her five short head quills point downwards, somewhat resembling a bob cut. She also has three spikes for bangs on her head and a short pointy tail. For attire, Amy wears a red sleeveless and backless dress with two white trims and a white petticoat underneath, tall red boots with a white stripe down the center, white cuffs and gray soles with chunky heels, a red hairband, and white wrist-length gloves with gold bracelets for cuffs. When she was younger, Amy's five head quills were longer and pointed backward, and she had a single back spine, her eyes were black. For attire, Amy wears an orange-ruffled or pleated skirt, a green puffy-sleeved shirt with a white collar and cuff bands, white and lavender sneakers with orange shoelaces, white wrist-length gloves, and a red ribbon headband. At one point in her young lifestyle, she wears a red dress, gold bracelets and red boots similar to what she would normally wearing.
She has large breasts. She's an adult. Her age is 18.
Amy looks up to Sonic and identifies herself as Sonic's self-proclaimed girlfriend despite Sonic sometimes appearing annoyed by her affections. During the Chaos incident, bored of her mundane city life, Amy resolved to become more independent to win over Sonic's heart and be a part of his adventures by the end of her tale, feeling she was something of a burden to him due to needing to be rescued time and time again. By the end of it, Amy even proclaimed she will be a greater hero than him one day and will get him to respect her. Even though he seems nervous and occasionally overwhelmed by her advances, Sonic at least considers Amy a good friend and worthy comrade and is always there to help her out should the need arise. Sonic's emotional neglect, for the most part, does not seem to hurt or deter Amy, as she believes he is merely hiding his feelings behind a facade, which has occasionally been implied to be the case.
