BOOM!
A sound as loud as an exploding nuke went off. The sky turned a dark shade of gray and poison mist filled the air. Everypony laid on the cold, hard ground, struggling to inhale the tiniest bit of oxygen. It was unknown what made this happen. But it sure was strange. Who would've known this would change everything in Ponyville and all of Equestria forever.
Slowly, Rainbow Dash managed to get up. Her head felt weird. Ponyville now looked weird. The mist was now gone. But the sky was still dark, gloomy, and gray. An electric-like shock stunned Rainbow in the head. Suddenly, something was telling her...... It was time for battle. She didn't know why. Could this be the effect of that weird noise? Or maybe, the poisonous air that was the previously? Rainbow Dash suddenly took off at the speed of sound flying through the sky. She then saw a pink earth pony walking through the moist grass. This was it. This was her opponent.
