This is how the Dazzlings meet Airacnid in Battle of the Machine Robos.
[We see the Dazzlings walking through a forest]
Aria Blaze: How long are we going to walk through this forest, Adagio? Without our pendants, we can't sing or cast our spell on someone.
Adagio Dazzle: Well, duh, because of those stupids half-pony riots. Besides, we won't be in this forest for very much longer.
Aria Blaze: Yeah. (To Sonata) Let's hope someone will help us with our dilemma.
[Sonata looks up and sees a giant spider-like shadow lurking in the trees]
Sonata Dusk: Umm, Dagi, Aria, I think someone is, like, watching us.
Aria Blaze: It's just your imagination, Sonat... [sees the spider-like shadow and nudges Adagio] Adagio, look!
Adagio Dazzle: Ugh! What now, Aria? [looks up and sees the spider-like shadow which jumps down and lands in front of them]
Adagio Dazzle: Who are you?
Airachnid: [comes out of the shadows] I am Airachnid. Where are OpThomas Prime and Ryan F-Freeman?
Aria Blaze: I think they are properly a few miles away from here.
Airachnid: Hang on. I remember you three. You're the Dazzlings. Aria Blaze, Sonata Dusk and Adagio Dazzle. Sirens banished from Equestria. You once tried to take over Cybertron. I saw those accursed Rainbooms defeat you at the Battle of the Bands. I feel very sorry for your power loss.
Adagio Dazzle: Question: Why are you looking for Ryan and Thomas?
Airachnid: Because I want to get even with the Trainbot for defeating Bowser on Cybertron and Ryan for defeating Megatron in Oz.
Sonata Dusk: Well, we've lost our pendants. And now we can't sing beautifully like we used to.
Airachnid: You're right, Sonata. Anyway, I'll make you a deal: I will give you three your powers back if you three help me get Ryan and OpThomas including my nemesis Arcee.
Adagio Dazzle: I do believe we have a deal.
Aria Blaze: Do you think that Airachnid will help us, Adagio?
Adagio Dazzle: I hope so, Aria. Soon, we'll make Ryan join the Dazzlings and make everyone in this world adore us.
Sonata Dusk: I hope you're right, Dagi.
[ As the Dazzlings follow Airachnid, words appear out of nowhere forming the title: Battle of the Machine Robos.]
[The song Rainbow Rocks starts playing]
