Amy resembles her modern counterpart when she was younger. Amy is an anthropomorphic hedgehog with a round head. She has pink fur that covers most of her body and peach skin on her muzzle and the inside of her ears, and black eyes. She also has five short quills on the back of her head, two triangular ears, a black button nose and a fringe consisting of three small quills. Protruding from her back is one additional quill - slightly smaller than the ones on her head - and a small, pointy tail.
Much like her appearance, Amy's attire follows her modern counterparts youthful clothing with exceptions for cold weather. Amy maintains her red ribbon tied into a headband, orange skirt, and blue and white sneakers with orange laces, but in place of a green blouse, she wears a green coat with white buttons and a thick white trim as well as white mittens instead of gloves.
Sonic Mania Adventures
During winter, Amy was taking a stroll on Angel Island when she tripped over a snow-covered Metal Sonic. Amy was startled at first, but Metal Sonic, being in a state of disrepair, made no attempt to hurt her. As a broken tree then began falling down on Metal Sonic, Amy swiftly saved the robot, only to get scared of him and start pounding him with her hammer when he looked at her. Seeing that Metal Sonic was still unresponsive though, Amy helped Metal Sonic on his feet. A Flicky then popped out of Metal Sonic and kicked him, causing him to fall down again. Noticing the heavy snow, Amy decided that she could not leave Metal Sonic and got him back to Eggman's lair after dragging him through Mushroom Hill Zone and IceCap Zone. There, she place Metal Sonic at the front door and made him presentable with a bow before ringing Eggman's doorbell. Before hiding behind some rocks though, she remembered to give Metal Sonic a flower and turn towards the front door. Eventually, Eggman opened the door and took Metal Sonic inside. While Amy was pleased by the sight, Sonic, who was watching nearby, was dumbfounded. Amy then sweetly gives Sonic a flower before taking off.
Other game appearances
While Amy herself does not make an appearance in Sonic Mania, and neither in Sonic Mania Plus, she has a cameo during the Metallic Madness Zone Act 2 boss fight, where Dr. Eggman uses robots shaped like Amy. These robots will try to hug the player and explode once they come in contact (unless shaken off).
Amy is shown to be a very kind and caring individual. Despite being afraid of Metal Sonic, she took pity on the robot when he was broken and abandoned. She is likewise very brave and selfless, having risked her own well-being to save Metal Sonic from a falling tree and dragged him across Angel Island in order to return him to Dr. Eggman.
Powers and abilities
Amy displays a degree of super speed, as she was able to swiftly push Metal Sonic out of path of a tree as it fell. Additionally, she was able to drag the robot across multiple Zones - all while going up an incline in the snow - without showing any signs of fatigue, suggesting a high level of strength and endurance.
