Twilight is teleported to Blood Gulch Canyon after meddling with a ship that crash landed in Equestria. She must enlist the help of the local red and blue soldiers to get home while unraveling a dark conspiracy linking her world to a shadowy agency.
They came down from the stars. The ponies called them heroes. They call themselves Decepticons. But whatever they are, they've made life good for the citizens of Equestria ... and Queen Celestia will not tolerate such insolence against her reign.
Cutie Mark Crusaders Time Travelers, yay! ...Wait, what? When older versions of Apple Bloom, Sweetie Belle, Scootaloo and Spike appear from the future, Twilight and her friends are in for an adventure that may decide the fate of time itself!
