This is how Airachnid betrays the Dazzlings goes in Battle of the Machine Robos.
Airachnid: I would love to give you three your powers back, but unfortunately, I can't.
Sonata Dusk: What?
Aria Blaze: What?
Adagio Dazzle: Why you won't give us our powers back, Airachnid?
Airachnid: I only pretended to promise you your powers back and wanted them for my own purposes. [creates her own Siren Pendant]
Evil Ryan: Wow, you made your own pendent just like the other three I made for me, Bertram and Evil Anna. [Coughs]
Megatron: Very impressive, Airachnid.
[Airachnid goes over to a computer and opens the Spacebridge. Three robots step through]
Heli Robo: Hi. I'm Heli Robo and these are my sisters, Military Robo and Stealth Robo.
Adagio Dazzle: I'm Adagio Dazzle and those two are Sonata Dusk and Aria Blaze. We are the Dazzlings. Sirens banished from Equestria.
Stealth Robo: We are a race of robots from Cybertron.
Military Robo: But you can call us Machine Robos.
Airachnid: These three robots will aid us in our conquest.
Adagio Dazzle: Impressive.
Twivine: Most impressive.
Airachnid: Okay, Machine Robos. I want you to find a Train-Prime named OpThomas and drain his memories.
Heli Robo: We would be honored to do so.
Evil Ryan: But, first. Can you three robots show us your abilities? [Coughs]
[The Machine Robos show off their abilities]
Evil Ryan:[clapping his hands] Bravo! Bravo!
Megatron: Wow, they're good.
Heli Robo: Come on, girls. Let's go find that Train-Prime and drain his memories.
[The Machine Robos step through the open Groundbridge]
Bertram T. Monkey: Do you think the Machine Robos are good, Aria?
Aria Blaze: Yes, Bertram. I think they are.
Evil Ryan: With the Machine Robos, we will have a chance against OpThomas' friends.
Sonata Dusk: How can Cybertronians like them have Siren abilities?
Bertram T. Monkey: I'm pretty sure that those three robots got gems on their chests like those pendants. [shows Sonata his Siren Pendant. It's like those pendants the Dazzlings wear, but the gem is purple]
Sonata Dusk: Okay. I have no idea why your pendant is purple.
Bertram T. Monkey: It fits my personality with Aria Blaze.
Aria Blaze: But the pendant looks like it was forged from Dark Energon.
Bertram T. Monkey: Actually, Aria. That pedant along with Evil Ryan's and Evil Anna's pendants are forged from gems from Crash Bandicoot's world.
Aria Blaze: Oh.
Adagio Dazzle: How does it work?
Evil Ryan: Now I'll tell you, Adagio.[Coughs] Those pendants allow me, Evil Anna and Bertram the ability to feed off negative energy and control people with our singing.[shows Adagio his Siren pendant.It's like those pendants the Dazzlings wear, but the gem is orange] C'mon Evil Anna. Show her your pendant.
Evil Anna: Ta-da! [shows Adagio her Siren pendant. It's like those pendants the Dazzlings wear, but the gem is blue]
Adagio Dazzle: Whoa!
Sonata Dusk: Amazing!
Aria Blaze: Wow!
Bertram T. Monkey: Yeah, wow.
Sonata Dusk: Can you demonstrate your singing for us?
Evil Ryan: Ok, Sonata. [puts on his Siren pendant] C'mon Bertram and Evil Anna. I think this calls for a song. Ah, ahh-ahh, ahh-ahhh!
Bertram T. Monkey: Right, Evil Ryan. [puts on his Siren pendant] Ah, ahhh-ahhh, ahhh-ahhh!
Evil Anna: Let's sing Battle of the Bands from the Dazzlings' Rainbow Rocks Movie. [puts on her Siren pendant]
[The song Battle of the Bands starts playing]
Evil Ryan: We heard you want to get together!~
We heard you want to rock this school~
We thought of something that is better~
Something that changes all the rules~
Why pretend we're all the same~
When some of us shine brighter?~
Evil Anna and Bertram T. Monkey: Shine brighter~
Evil Ryan: Here's a chance to find your flame~
Are you a loser or a fighter?~
Evil Ryan, Evil Anna and Bertram T. Monkey: Me and you, you and me~
Why don't we see who is better?~
We don't have to be one in the same thing~
Oh, what's so wrong with a little competition~
Are you afraid of failing the audition?~
Evil Ryan: You're a star and you should know it~
Yeah, you rise above the rest~
It doesn't matter who you hurt~
If you're just proving you're the best~
Evil Ryan, Bertram T. Monkey and Evil Anna: Ah, ahh-ahhh~
Battle! You wanna win it~
Let's have a battle, battle of the bands~
Let's have a battle, we'll go all in it~
Let's have a battle, battle, battle~
Battle of the bands~
Battle!~
Sonata Dusk: I could beat you!
Evil Ryan, Bertram T. Monkey and Evil Anna: Battle!~
Kaos: Ha! You wish.
Evil Ryan, Bertram T. Monkey and Evil Anna: Battle!~
Twivine: I so want this.
Evil Ryan, Bertram T. Monkey and Evil Anna: Battle!~
Breakdown: Not if I get it first!
Evil Ryan, Bertram T. Monkey, Evil Anna and the rest of the villains: Me and you, you and me!~
Why don't we see who is better?~
We don't have to be one in the same thing~
Oh, what's so wrong with a little competition?~
Kaos and Twivine: I'm going out and winning the audition~
Diesel 10, Evil Anna and Breakdown: Battle! We wanna win it~
Megatron, Soundwave, Bertram T. Monkey and Starscream: Let's have a battle, battle of the bands~
Shockwave, Evil Ryan and Sunset Shimmer (Opposite): Let's have a battle, we'll go all in it~
Dreadwing, Thundercracker, Dr. Neo Cortex, Evil Ryan, Bertram T. Monkey and Evil Anna: Let's have a battle, battle, battle~
Battle of the bands~
[As the other villains argue, Evil Ryan, Bertram and Evil Anna smile at their handy work]
Evil Ryan: Nice job, guys.
Bertram T. Monkey: Yeah, we did well like the Dazzlings.
Evil Anna: Airachnid won't be too happy though.
Evil Ryan: She won't notice that the villains are under our spell, Evil Anna. Let's use our pendants to absorb the negative energy.
Bertram T. Monkey: Ok.
[The pendants glow as the negative energy is absorbed]
Evil Ryan: Oh yeah, that's more like it.
Bertram T. Monkey: But what can we do to stop Airachnid from finding out what we've been up to?
Evil Ryan: I've got an idea. Just follow my lead.
Evil Anna: Righty-o, Evil Ryan.
Bertram T. Monkey: So what's the plan?
Evil Ryan: We'll follow Airachnid and see what she's up to.
Evil Anna: And then what?
Evil Ryan: And then, we'll tell her that we are training the villains for a battle against Ryan F-Freeman and his friends.
Bertram T. Monkey: And then?
Evil Ryan: We hypnotize her with our singing.
Bertram T. Monkey: Ok. Let's go.
[The three head off into the night]
Evil Ryan: Are you sure this will work?
Bertram T. Monkey: Sure it'll work, Evil Ryan. I hope Airachnid can sing something.
Evil Anna: I hope so too.
Evil Ryan: Me too, Evil Anna.
[Later]
Evil Ryan: Hi, Airachnid.
Airachnid: Oh. Hey.
Evil Anna: My friends and I thought that we are training the villains for a battle against Ryan, Thomas and their friends.
Airachnid: Well, how nice.
Bertram T. Monkey: Yeah. I hope you like your pendant. Because of what Adagio said.[touches the purple gem of his pendant and starts talking like Adagio Dazzle] Their negative energy will give us the power we need to get this entire world to do our bidding.
Airachnid: I know.
Evil Ryan: Um, Bertram. Why are you talking in Adagio's voice?
[Bertram removes his finger]
Evil Anna: Can you tell us, Bertram?
Bertram T. Monkey: I was talking in Adagio's voice because of my pendant.
Evil Ryan: It looks like our pendants give us the ability to talk in someone else's voice.[to Airachnid] Can yours do that?
Airachnid: Not sure.
Evil Ryan: Give it a try, Airachnid.
[Airachnid presses her pendant and starts talking like Starscream]
Evil Ryan: Does it works, Airachnid?
Airachnid: [in Starscream's voice] Yes.
Evil Anna: Well done, Airachnid. Let me say Sonata's line.[touches the blue gem of her pendant and starts talking like Sonata Dusk] Hello. We sing, like, all the time. It's how we get people to do what we want.
Evil Ryan: Yeah. I sometimes find that line annoying.
Evil Anna:[in Sonata's voice] Wha-what did I say?
Evil Ryan: Evil Anna, you said what Sonata said. And I find it annoying sometimes.
Evil Anna:[in Sonata's voice] Ohhhh, yeah! What you said I meant to say. That's what I meant. To say.
Bertram T. Monkey: You can stop talking like Sonata now.
Evil Anna:[removes her finger off her pendant] Better. Sonata will be happy when Evil Ryan uses his magic to fix her pendant.
Evil Ryan: I know.
Bretram T. Monkey: I'll put that on my to-do list.[does so] You want to have a go, Evil Ryan?
Evil Ryan: No thanks.
Evil Anna: C'mon, Evil Ryan. It's easy. Touch your pendant and talk in someone else's voice.
Evil Ryan: No way.
Bertram T. Monkey: I've got my go. I suggest you will do the same.
Evil Ryan: Ugh! Fine. [touches his pendant]
Evil Anna: Ok, Evil Ryan. Say something what Midnight Sparkle said after Sci-Twi transformed.
Evil Ryan: [in Midnight Sparkle's voice] You were right. I didn't understand magic before. But I do now!
Bertram T. Monkey: Bravo, Evil Ryan. You did well saying that line.
Evil Ryan: [removes his finger] Thanks.
Evil Anna: Guess our pendants gave us this ability. We could use it in other movies.
Evil Ryan: You said it.
Bertram T. Monkey: Let's hope that Mal doesn't have a pendant around his neck.
Evil Ryan: [scoffs] Like that would ever happen. [to Airachnid] Can you sing a song with us?
Airachnid: Sure. How about the Total Drama theme song.
Evil Ryan: That's great idea. After that we'll sing What More Is Out There.
Airachnid: Alright. Hit it!
Evil Ryan: Hitting it. [coughs]
[The Total Drama theme song plays]
