Transformers and Equestria Girls: Robots in Disguise

Meanwhile at the Canterlot Music Stadium, the Dazzlings started vocalizing.

The Dazzlings

Ah-ha, ah-ah-ah, ah-ah-ah
Ah-ah-ah-ah-ah
Ah-ha, ah-ah-ah, ah-ah-ah
Ah-ah-ah-ah-ah

Adagio Dazzle

Welcome to the show

Sonata Dusk and Aria Blaze

Ah-ah-ah-ah, ah

Adagio Dazzle

We're here to let you know

Sonata Dusk and Aria Blaze

Ah-ah-ah-ah-ah-ah

Adagio Dazzle

Our time is now

Sonata Dusk and Aria Blaze

Ah-ah-ah-ah, ah

The Dazzlings

Your time is running out

Sonata Dusk and Aria Blaze

Ah, ah, ah

The Dazzlings

Ah-ha, ah-ah-ah, ah-ah-ah
Ah-ah-ah-ah-ah...

The Rainbooms suddenly saw the Dazzlings vocalizing from afar. “How are we supposed to play over them from up here?” Rainbow Dash asked, until Vinyl Scratch transformed her car into a portable DJ booth and the Rainbooms cheered.

“Awesome!” Pinkie Pie exclaimed. “Sweet!” Rainbow Dash said.

The Dazzlings

Feel the wave of sound
As it crashes down
You can't turn away
We'll make you wanna sta-a-a-ay

We will be adored
Tell us that you want us
We won't be ignored
It's time for our reward

Now you need us
Come and heed us
Nothing can stop us now

The Rainbooms

Oh-oh, oh-whoa-oh
I've got the music in me
Oh-oh, oh-whoa-oh

Twilight Sparkle

Don't need to hear a crowd
Cheering out my name
I didn't come here seeking
Infamy or fame

The Rainbooms

The one and only thing
That I am here to bring
Is music, is the music
Is the music in my soul

Gonna break out (Out!)
Set myself free, yeah
Let it all go (Go!)
Just let it be, yeah

Find the music in your heart
Let the music make you start
To set yourself apart

“So the Rainbooms want to turn this into a real Battle of the Bands? Then let's battle!” Adagio asked while smirking, until she and the other two continued singing.

The Dazzlings

What we have in store (ah-ah)
All we want and more (ah-ah)
We will break on through (ah-ah)
Now it's time to finish you!

The Dazzlings’ eyes turned red as they unleashed their full power, and then revealed themselves as the Sirens, and swarmed towards the Rainbooms.

Twilight Sparkle started vocalizing, until the Sirens also started vocalizing, before Twilight dropped the microphone towards Sunset Shimmer, “Sunset Shimmer, we need you!”

The Sirens swarmed around the Rainbooms until Sunset began singing.

Sunset Shimmer

You're never gonna bring me down
You're never gonna break this part of me
My friends are here to bring me 'round
Not singing just for popularity

Sunset Shimmer and Twilight Sparkle

We're here to let you know
That we won't let it go

The Rainbooms

Our music is a bomb and it's about to blow

Sunset Shimmer and Twilight Sparkle

And you can try to fight
But we have got the light of

The Rainbooms

Friendship on our side!

Got the music in our hearts
We're here to blow this thing apart
And together, we will never
Be afraid of the dark

Here to sing our song out loud
Get you dancing with the crowd
As the music of our friendship
Survives, survives!

All sans Dazzlings

Got the music in our hearts
We're here to blow this thing apart
And together, we will never
Be afraid of the dark

Here to sing our song out loud
Get you dancing with the crowd
As the music of our friendship
Survives, survives, survives!

The sky formed a huge alicorn made of energy with a rainbow colored mane and tail. A huge ball of fire suddenly came from the sky and passed by the rainbow laser until it destroyed the Sirens and the Dazzlings’ pendants.

The Dazzlings got back up and then started singing off-key.

The Dazzlings

We will be adored
Tell us that you want us
We won't be ignored
It's time for our reward...

The crowd booed at them as the Dazzlings ran off the stage while the crowd threw tomatoes, eggs and lettuce at them.

“Guess that explains why these were so special to them,” Sunset said, as he held a piece of the pendants. “Without those pendants and the magic you brought here from Equestria, they're just three harmless teenage girls,” Twilight said.

“Rainbooms rule! That was amazing!” Flash Sentry cheered, as he hugged Twilight before they both blushed bashfully. Sunset Shimmer and the other 5 giggled at the cute moment.

“You may have vanquished the Dazzlings, but you will never have the amazing, show-stopping ability of the Great and Powerful Trixie!” she said, before the magician girl disappeared with a puff of smoke.

The Rainbooms, Sunset Shimmer, and Flash Sentry were coughing from the smoke. Pinkie Pie gasped, “She's gone! Oh, wait. There she is.”

Trixie Lulamoon tripped over the stairs, “Trixie's okay!”

“You know, Twilight is going back to Equestria soon. The Rainbooms could really use someone to help Fluttershy on backup vocals,” Rainbow Dash said, until Sunset played guitar riff, “I also play guitar.”

“We'll see,” Rainbow Dash said. “By the way, did anyone notice that ball of fire in the sky?”

“I think I did,” Sunset said. “But we should probably get ready to say goodbye to Twilight tomorrow.”

Meanwhile, the Autobot ship was headed towards the lake and mountainside of the Everfree Forest. “Autobots! Brace for impact!” Optimus said as the Autobots held on for dear life, and suddenly, the ship crashed into the mountains, and then made some damage. The Autobots were suddenly knocked out.

The next day, the Rainbooms were at the statue getting ready to say goodbye to Princess Twilight and Spike, the dragon-turned-dog.

“Sure wish you could stay longer,” Applejack said.

“Me too. But I have responsibilities in Equestria that I have to get back to. Its citizens need me. But now I can go through the portal whenever I need to. This isn't goodbye. It's just goodbye 'til next time,” Twilight said, until she looked at Spike. “Ready?”

“Ready!” Spike said, as he and Twilight walked through the portal together.

At the stadium, Sunset was writing a letter to Twilight.

”Dear Princess Twilight,
Missing you already, and I hope you'll be back soon. Things are definitely looking up for me here at Canterlot High. But I know I still have a lot to learn about friendship. Hope you don't mind if I write to you for advice when I need it.
Your friend, Sunset Shimmer.”

“Rainbow Dash took her guitar and looked at Sunset, “You ready or what?” Sunset walked over and grabbed her guitar, “Ready!”

Meanwhile, the human world’s version of Twilight Sparkle gathered a seismic wave and pinned it on her cork board, and then talked to her dog, Spike, “No doubt about it, Spike. There's definitely something strange going on at that school…”

Spike then barked in reply while Sci-Twi stroked her chin feeling curious about Canterlot High’s energy readings.
