Starlight Glimmer returns to take revenge against Twilight Sparkle and her friends for ruining her utopian society. To do this, she alters Star Swirl the Bearded's time travel spell so it allows her to travel back in time to the point Rainbow Dash performed her first Sonic Rainboom, which allowed her friends to obtain their cutie marks at the same time. Twilight and Spike follow after her, but fail to stop her from sabotaging the race. The two return to the present to find that Equestria is at war with King Sombra, yet the Cutie Map remains and grants Twilight and Spike access to reuse Star Swirl's spell. They fail to stop Starlight a second time, and return to another future ruled by Queen Chrysalis. Twilight and Spike become trapped in a time loop as they repeatedly fail to stop Starlight from altering the past, which creates progressively worse versions of Equestria dominated by other villains such as Nightmare Moon, Lord Tirek, Discord and the Flim Flam brothers. Finally, they forcibly take Starlight with them to show how her actions are ravaging Equestria. Starlight refuses to believe them and shows them her own childhood, revealing that she was separated from her friend Sunburst the day he earned his cutie mark and left to study at Celestia's school for gifted unicorns. Understanding Starlight's fear of losing friends because of their talents, Twilight convinces her to give friendship another chance, and they return to the unaltered present together. After deliberating with her friends, Twilight decides to take Starlight on as her student and accept her as one of their friends.
