Shadow is the "Ultimate Life Form" created aboard the Space Colony Ark over fifty years ago by Professor Gerald Robotnik. He is the final result of Project Shadow, a government experiment that was only completed by infusing Shadow with the DNA of the alien Black Doom. After his birth, Shadow befriended Gerald's granddaughter, Maria. However, the Guardian Units of Nations (G.U.N.) deemed the project a threat and raided the ARK, resulting in the captures of Shadow and Gerald, and the death of Maria. Driven to madness, Gerald altered Shadow's memories to one day seek revenge.
