Chapter 1: Shadowbolts

At Fluttershy's cottage, Tank spends time with Angel at Fluttershy's insistence while she and Rainbow Dash catch up. All of a sudden, Applejack bursts in and alerts the two of an emergency: Queen Chrysalis and the changelings are attacking the Crystal Empire. Excited to go to battle with her fellow Wonderbolts, Rainbow Dash speeds out the cottage door.

On her way to regroup with the Wonderbolts in Canterlot, Rainbow runs into the Shadowbolts – originally illusions created by Nightmare Moon but now granted physical form. The Shadowbolts taunt Rainbow to chase after them and fly off into the Everfree Forest. Rainbow briefly wrestles with the choice of joining the Wonderbolts in quelling Chrysalis' invasion or stopping the Shadowbolts before they cause trouble in Ponyville, and she decides to follow the Shadowbolts.

The Shadowbolts challenge Rainbow Dash to a race; if she wins, they agree to share all of their secrets with her. If she loses, she has to join their team. After receiving some more taunting, Rainbow accepts their challenge. The three race across a canyon on the outskirts of the forest, and the Shadowbolts immediately engage in some foul play, like taking off early from the starting line and shoving Rainbow in mid-flight. Despite this, however, Rainbow eventually beats them by making them crash into each other and into a hollow tree.

Much to Rainbow's surprise, the Shadowbolts are revealed to be changelings in disguise. They were tasked with distracting Rainbow from making it to Canterlot in time to stop Chrysalis' invasion. However, believing she can still make it in time, Rainbow dismisses the two changelings and takes off toward Canterlot, leaving the changelings in their miserable state.
