Nazo the hedgehog [Sonic: Nazo unleashed]

You were sure that Nazo would never return when Sonic and Shadow defeated him. You knew that he was a serious opponent, because Nazo is the embodiment of the negative energy of Chaos.

But your rest was interrupted by someone's presence. You raised your head and saw a hedgehog that looked like Sonic and Shadow. His fur was light blue and covered his entire body. It was Nazo. But where did he come from? Your body involuntarily trembled, not ready for such a change..
