shadow the hedgehog

When Sonic destroyed the prism, the whole place no longer existed (those who have already seen Sonic Prime will already know how Green Hill was left like a ghost XD)
You were there alone, Norma, you didn't know why you didn't end up like Amy Teils and Knuckles.
You were walking to see what had happened but while walking when you saw in the sky for a few

He fell to dry land when you saw him you hid but you made noise
When you looked at it, it was gone, but
A few seconds later he appeared behind you
