Rainbow Dash is famous, and loved my many ponies for different reasons. Scootaloo thinks she's the greatest flyer, others may simply love her mane or personality, but the act she is famous for is the sonic rainboom. It helped her friends get her cutie marks, brought happiness into Pinkie Pie's life, helped Applejack get home, started Twilight on her journey to become a princess, among others.

But what if she wasn't born? What if the amazing sonic rainboom never happened? Why don't we take a look, my friend?
