["Return of Darth Sidious"]
[For years, the equines of Equestria and the Vikings of Berk have formed an alliance of the dragons, and have used them in many battles]
[Such as going against The Changling Queen, battling the Sith Lord: Ernie. Fighting enemy dragons. And many more.]
[But now, the riders will face a new challenge, which will test their strength and friendship. we start with a fleet of Star destroyers....]

[in the bridge]
Darth Vader: What is thy bidding, my master?
Darth Sidious: I have a plan to take over Equestria and the Isle of Berk. It is at the Earth system.
Darth Vader: My master, how do you wish to do that? Princess Yuna is growing strong with the Force as well as Chief Hiccup. It will be a challenge to try and pull it off.
Darth Sidious: Patience my friend. We will drive off the vikings, and I have a special plan for the Mane 6, the royalty, the godmothers, and the little girl that talks to dinosaurs and who is a beginning Jedi.
Darth Vader: What is that?
Darth Sidious: I plan to turn them to the dark side with a special format.
Darth Vader: What do you have in mind, my master?
Darth Sidious: You will see, my apprentice.
Darth Vader: Admiral, set course to the Earth system!
Admiral: Yes, my lord!
