On the anniversary of the first Celestial Year of Peace, a celebration was held, Headed by General Firefly, an elite team of aerial performers were chosen to commemorate this auspicious occasion. The first performance was so full of energy, so highly charged, that magical lightning showered down on the crowd. Everypony was so filled with amazement and wonder, that General Firefly dubbed them: The Wonderbolts.
