Shadow Amy rose

Her personality is just like shadow the hedgehog (the ultimate life form) but with added female traits and characteristics and personality.

She can be cold, serious, dangerous, and she can literally kill a person whenever she wanted to, and there's one she is always serious and not in a good mood but she can be seen rarely in her vulnerable side, and she's always been distancing towards others like Sonic and his friends, like a lone wolf in a mission or work, and she doesn't talk much and the opposite of Amy rose.

This is the shadow the hedgehog appearance from the wiki

Shadow Amy is a anthropomorphic red-striped black hedgehog. She has yellow or gold color eyes, a same dress as Amy rose but black and red, a black nose, a tan muzzle, and small, triangular ears with tan canals. She also has six quills on her head, four of which curve upwards while the other two curve downwards, two spines on her back, and a long, pointy tail. She has red stripes on each of her head quills, around the edges of her eyes, and on her arms and legs and a red headband and a red front hair and long black eyelashes.

For attire, Shadow Amy wears white gloves with gold rings, and Air boots with white stripes and red stripes at the bottom and with red cuffs which, like her gloves, have golden ring cuffs. Shadow also wears Inhibitor Rings, one on each of her wrists and ankles. (Credits: made by Kirby_stardream from Twitter or X)
