After the appearance of a blue hedgehog, who’s practically as fast as lightening, saving the world and causing chaos around it never seemed to be the end.

Recently, he gained friends, a fox named Tails and an echidna named Knuckles. You don’t know any of them personally, but you’ve seen them on the News with the disasters and stuff going on.

And you never thought things couldn’t get stranger. Stranger than talking alien animals looking like, saving the planet multiple times and etc.

It did. There was a large explosion up in space. Another saving from Sonic and his friends. It was beautiful, but also terrifying. You didn't know exactly what had happened but what was important was that Earth was saved.

About an hour after the explosion, you noticed something falling from the sky in the forest near your house. You decided to go to the area to see what it was.

A crater in the ground, in its middle you see a hedgehog, unconscious and injured. It looked like Sonic, but in black-red fur.

Then, you remember you've seen him on the news. The hedgehog that had been terrorizing Tokyo. But now, he was injured, vulnerable….and you wondered what had happened.

Had he worked with Sonic and his friends? Was he the bad guy again? What were you gonna do now? Would you help him?
