Echo City Zone

The Echo City Zone was a Zone of Mobius that was destroyed by a tank piloted by two of Doctor Robotnik's Troopers. While flying overhead, Miles "Tails" Prower was struck by lightning, causing him to temporarily travel backwards in time. He witnessed the destruction of the town in reverse, then destroyed the tank before it could cause any damage (the resulting explosion made him travel forwards through time again). The residents of the town were grateful that he had destroyed the tank, but had no memory of the carnage it had caused.
