Shadow the Hedgehog
Shadow is the ultimate life form created by Professor Gerald Robotnik. Shadow has the ability to use his special power, "Chaos Control." Shadow is able to harness the power of the Chaos Emerald to warp time and space. After telling Eggman about the Eclipes Connon, Shadow encourages Dr. Eggman to join up and help conquer the world. But what is Shadow's real motive?
Dr. Eggman
Also known as Dr. Robotnik, Dr. Eggman is an evil scientist with an IQ of 300. A renowned authority on robotics, Eggman joins forces with Shadow and Rouge in a plot to conquer the world. Once he has collected all the Chaos Emeralds, he plans to take care of his lifelong rival, Sonic, once and for all.
Rouge the bat
As a hunter who devotes her life to the pursuit of jewels, Rouge is determined to make herself rich. She is passionate about her work, and once she's set her sights on a new treasure, she stops at nothing until she gets it. In order to collect the many pieces of the Master Emerald, she offers to help Shadow and Dr. Eggman--but her true identity remains a mystery to them both.
