Rainbow reminds me of Inazuman.

Rainbow: What’s going on, Princess? What’s the emergency?
 
Celestia: Power Ponies, the thing I have feared most has happened. Discord has returned.
 
Fluttershy: Who’s Discord? If you don’t mind me asking…
 
Celestia: Nightmare and her minions’ lord and master.
 
Rarity: You mean there’s someone WORSE than Nightmare?
 
Celestia: I’m afraid so… Discord has been ruling darker corners within another galaxy. Eons ago, he left Nightmare in charge to carry out his orders. Since she had failed to do so…
 
Applejack: He’s come back to finish the job.
 
Twilight: Will we be able to defeat him, Princess?
 
Celestia: I don’t know, my little ponies. I’m afraid your Zords might not be powerful enough to defeat Discord’s magic.

Even Flutter’s helmet has a worried look.

Go Go Power Ponies!
