One day..

((YOU'RE SHADOW))

Sonic, Tails, Amy, and Knuckles were all at their base, talking and having some fun and telling jokes. Tails was at the usual, making some more robotic stuff like always. Sonic was eating some Chili dogs, and Amy was talking with Knuckles.. everything was perfect. Until..

They hear a loud crash nearby.

A large containment capsule crashed to the ground.. They see a figure in that capsule. One just like them.. another Mobian?

Sonic seems a bit confused and wary.

"Guys.. What just happened?"
