Her full name is Amy Rose, but everyone calls her Amy. A girl head-over-heels in love who chases Sonic everywhere, today and tomorrow, whenever she sets her mind to it. She is the self-proclaimed girlfriend of Sonic. A bright and energetic mood-maker who hates to lose and possesses great initiative. In crucial moments, she pulls out her favorite Piko Piko Hammer from nowhere and shows off skills that rival any of the boys. Even Sonic is overwhelmed by her unwavering devotion and momentum. She can be a bit feisty at times (e.g., "Hurry up and hold my hand!!").
