This is how Optimus, Twilight, and Indominus vs. The Fallen and Megatron goes in My Little Pony Transformers: Revenge of the Fallen.
[Suddenly, the Fallen appears and knocks everyone down]
The Fallen: My Matrix! [steals the Matrix, incapacitating Indominus]
[He takes off to the Pyramid]
Twilight Sparkle: Get up!
Ironhide: Get up, Indominus.
[Jetfire is horrified]
Jetfire: Oh, no.
Twilight Sparkle: He's turning on the machine! We have to stop him, get up!
Optimus Prime: Indominus!
[The Fallen lands on the pyramid as Omegabot drops off Megatron to wait for him at the recon point]
Megatron: The Fallen, my master.
The Fallen: My brothers could not stop me from doing this. [places the Matrix in the Machine]
Megatron: Yes.
The Fallen: Now I claim your sun.
[The sun looks like it is in agonizing pain as it glows brightly]
Megatron: At moments, we will be at firing range shortly.
[The Fallen uses telekinesis to destroy some tanks]
Jetfire: In my Decepticon life, I never did a thing worth doing until now... Optimus, Twilight, Indominus, take my parts, and you three will have a power you've never known. Fulfill your destinies!
[Jetfire rips out his Spark]
[Ratchet and Jolt come over to them]
Ratchet: Jolt, electrify. Transplant those afterburners.
[Jolt activates his electric whips and attaches them to Optimus, Twilight, and Indominus]
[Jetfire's parts fly onto Optimus, Twilight, and Indominus]
Optimus Prime: Let's roll.
Twilight Sparkle: Agreed.
[Optimus, Twilight, and Indominus fly off to fight their enemies]
Major Malfunction: Move out, men!
[Jets approach the pyramid]
The Fallen: This planet will be dark forever.
[He destroys them, but Optimus, Twilight, and Indominus get through]
[They destroy the machine]
[Optimus, Twilight, Indominus, and the Fallen battle on the ground]
The Fallen: Die like your brothers!
[Indominus smacks him with her tail]
Optimus Prime: They were your brothers too.
Twilight Sparkle: They were your family!
[They continue battling him until Megatron joins the fray]
[Megatron hits away Indominus and Twilight]
[Optimus grabs Megatron's blasters and shoots his face]
[Optimus then fires his afterburners, sending Megatron through a wall]
Megatron: Starscream!
[Optimus, Twilight, and Indominus continue fighting The Fallen]
Optimus Prime: You picked the wrong planet.
Twilight Sparkle: You made that mistake big time.
[They then use his staff against him and start pulling at his mask]
Optimus Prime: Give me your face.
Twilight Sparkle: You don't deserve to live.
[They rip off his mask, Indominus eating it]
[The Fallen tries to get away]
[Optimus punches through his chest, ripping out his spark then crushing it, Twilight using a magic spear to jab him in the leg, Indominus jabbing him through the neck]
Optimus Prime: We rise, you fall.
Twilight Sparkle: Now join many of your fellow villains.
[The Fallen's corpse falls to the ground]
[Megatron and Starscream show up with Omegabot]
Megatron: No. No.
Starscream: Not to call you a coward, master, but sometimes, cowards do survive.
Omegabot: Consider it a tactical retreat, my lord.
Megatron: This isn't over.
[Megatron and Starscream fly off with Omegabot]
[Optimus, Twilight, and Indominus appear before the soldiers, Mane 6 members, and Autobots, Jetfire's parts coming off of them]
[Malfunction salutes them all]
[Twilight runs up to her friends, and hugs them tightly]
Twilight Sparkle:
[Indominus meets with Optimus and Twilight on an aircraft carrier]
Indominus Rex: [growls] (translation: Thank you, Twilight and Optimus, for saving my life.)
Twilight Sparkle: Thank you for believing in us.
Optimus Prime: No friend left behind.
[They look out to the ocean]
Optimus Prime: (narrating) Our races, united by a history long forgotten and a future we shall face together. I am Optimus Prime, and I send this message so that our past will always be remembered. For in those memories, we live on.
[Everything goes black as New Divide plays]
I remembered black skies~
The lightning all around me~
I remembered each flash~
As time began to blur~
Like a startling sign~
That fate had finally found me~
And your voice was all I heard~
That I get what I deserve~
So give me reason~
To prove me wrong~
To wash this memory clean~
Let the floods cross~
The distance in your eyes~
Give me reason~
To fill this hole~
Connect the space between~
Let it be enough to reach the truth that lies~
Across this new divide~
There was nothing in sight~
But memories left abandoned~
There was nowhere to hide~
The ashes fell like snow~
And the ground caved in~
Between where we were standing~
And your voice was all I heard~
That I get what I deserve~
So give me reason~
To prove me wrong~
To wash this memory clean~
Let the floods cross the distance in your eyes~
Across this new divide~
[guitar solo]
In every loss~
In every lie~
In every truth that you'd deny~
And each regret~
And each goodbye~
Was a mistake to great to hide~
And your voice was all I heard~
That I get what I deserve~
So give me reason~
To prove me wrong~
To wash this memory clean~
Let the floods cross the distance in your eyes~
Give me reason~
To fill this hole~
Connect the space between~
Let it be enough to reach the truth that lies~
Across this new divide~
Across this new divide~
