Amy Rose also known as Rosy the Rascal, is a character that appears in the Sonic the Hedgehog series. She is an anthropomorphic hedgehog with a major crush on Sonic the Hedgehog. Since meeting Sonic on Little Planet, Amy has become his self-proclaimed girlfriend and has attempted to win his heart by any means in many of their adventures. She wields the Piko Piko Hammer, which she uses with skills second to none and never leaves home without it.

Bold, cheerful, romantic and fearless, Amy is a proactive go-getter that goes after what she wants and lets nothing get in her way. Amy is described as an "energetic tomboy," though by the time of the Chaos incident, she is shown to have traditional feminine interests nonetheless, such as shopping and fashion. She also hates boredom and loves thrills and excitement and openly expresses her emotions and feelings without a problem or what others think.
