After Amy (a playable character) complains about being bored, a bird wearing a Chaos Emerald necklace crashes into her in Sonic Adventure. She keeps the bird safe from E-100 Alpha, one of Eggman's robots. Amy later meets Sonic, and invites him to an amusement park (where they become separated). Alpha reappears, imprisoning Amy and the bird on Eggman's airship the Egg Carrier. Another Eggman robot, E-102 Gamma, orders Amy to give the bird to him; she refuses, asking him why he wants it. He does not know, and changes his mind when she tells him he is missing out on love. E-102 Gamma lets them leave and, touched, Amy becomes his friend before she escapes into the ship's interior. On the deck, Eggman confronts her and grabs the bird's Chaos Emerald. Sonic and Gamma appear, and when Sonic tries to destroy Gamma Amy defends him. Sonic agrees to spare Gamma, and Amy leaves with Tails. She later sees a photo of the bird and its parents (whom Eggman has also stolen) in its necklace. When Amy looks for them in the jungle, she again finds the Egg Carrier. The bird's parents emerge on the deck; Alpha appears, and injures Amy's bird. Amy destroys Alpha, and waves goodbye to the three departing birds.
