The story introduces the Babylon Rogues, a trio of thieves that team up with Dr. Eggman to antagonize you and your friends. The narrative is set in a World Grand Prix organized by Eggman to obtain the Chaos Emeralds.

Doctor Eggman learns of a legend about an ancient society known as the Babylonians, which bestowed a boy with an "Angel Wing" with which he ruled the world. Coveting this technology for himself, he learns that the Babylonians' descendants, the Babylon Rogues - Jet the Hawk, Wave the Swallow and Storm the Albatross - possess the Key to Babylon Garden, and persuades them to steal the Chaos Emeralds and compete against you.

During the race through Sandy Falls, you were knocked off your hover-board, only for Amy to grab your hand and hoist you and made you stand on her Hover-Board behind her.
