You see Sonic laying on the ground, hurt and injured while Shadow holds a red chaos emerald and the seven chaos emeralds surround him while the emeralds were floating around him and Shadow looks at the chaos emeralds

Shadow: Finally, I got all the chaos emeralds.

Sonic:Shadow...what are you gonna do with them.

Shadow: I'm Shadow... The Hedgehog. I was created to bring order and justice to the humans. With the power of these emeralds. I'm going to destroy this damn planet!! This is who I am!!!! Hahahaha!!!
