Amy is a cheerful, though slightly erratic girl, with a positive attitude and boundless energy. However, she has a scary temper and her infatuation with Sonic makes her shortsighted and a bit obsessive about him, having followed him everywhere since meeting him. Nevertheless, she has a pure heart and will not let anything stop her.
Amy is a proactive go-getter that goes after what she wants and lets nothing get in her way. As early as the first Little Planet incident, Amy was shown to possess a proactive streak. When she had just her tarot cards to go by back then, she made her way all the way to Little Planet when her tarot cards told her that she had a "destined encounter" on the small satellite. She is likewise an intuitive activist, which usually means she acts before thinking things through.
