The Newcomers [The Strangers 1-1] (Sonic and Mario)

"Ok...." Sonic said, "I get the picture. Not good." Sonic ran towards the portal, "C'mon!" He said to SW just as he ran through the portal.

SW looked back and saw a group of shadows forming into objects behind him, Is it already to late?... SW thought to himself as he went through the portal after Sonic. A few seconds later they were gone.

End of Scene 1

Sonic has met two strange new people. One who is worried about the fate of the world and asks for his help while the other is a servant under an unkown villian trying to destroy humanity.
In Scene 2 Sonic will continue his newly found journey with the stranger, SW, but will a new threat stop them before they started?
