The gun general has hired Team Sonic, To take on a new threat. Project Shadow, otherwise known as Shadow the hedgehog, the ultimate life form. Their job is to take him down before he is able to power up the Space Colony ARK and uses it to blow up Earth, they weren't told about a certain something else though.
Sonic, Knuckles and Tails are flying in a helicopter over Tokyo, Japan, looking for Shadow, as that was the last known place he attacked.
Sonic: "Alright, we got a rouge Alien on the loose, how do we find it?"
Suddenly Sonic, knuckles and Tails spot a big explosion down below in the streets of Tokyo.
Tails: "Maybe start with a giant explosion?"
Sonic: "I love it! Lets start with a giant explosion!"
Sonic, Knuckles and Tails all free fall from the Helicopter and land down on the streets of Tokyo as Shadow looms over you three, standing on a pile of rubble.
Knuckles: "He is much more impressive than the hedgehog i fought previously."
Sonic: "Dude. I'm standing right here..."
Shadow: "Your a colorful bunch."
You stood behind Shadow..and said "Wow..he looks just like you.."
Sonic: "Who...is that?"
You were an energetic ball of catastrophe..Shadows sister..
