This is how Into The Breach goes in Thomas' Adventures of Transformers Prime: The Movie.
[A Dark Energon meteor is being pulled through space by the Nemesis]
Vehicon: The anchor's holding, Lord Megatron. Output readings remain stable
Megatron: Perfect. The Dark Energon contained within that meteor will soon be mine.
[Megatron looks at the Dark Energon meteor and grins]
[Meanwhile at Autobot Outpost Omega One]
Ratchet: Something's wrong.
Thomas: I can see that.
Princess Celestia: What are the Decepticons up to this time?
[Autobot Outpost Omega One computer shows image of the Nemesis pulling the Dark Energon meteor]
Princess Luna: Whoa!
Thomas: What is that?
Ratchet: That's Dark Energon. The lifeblood of Unicron himself.
Starlight Glimmer: Inside a meteor?
Thomas: How can that be possible?
Optimus Prime: We must stop Megatron's plan before it is too late.
Twilight Sparkle: I agree.
Thomas: [fires up the Groundbridge] Then what are we waiting for? Let's go.
Donald (Thomas and Friends): Behind you all the way, lad-y.
Douglas: Me too.
Edward: I'm in.
Percy: I'm with you, Thomas.
Optimus Prime: I'm sorry but you must stay here. Twilight and her friends will be all the company we need.
Thomas: Then why can't we go, Prime?
Optimus Prime: Because I feel a being with the essence of Unicron within that meteor through the Matrix.
James: And you think we Trainbots won't be able to take it on?
Optimus Prime: It is best if you remain here.
Thomas: But what if you need back-up?
Optimus Prime: Twilight and her friends will be our back-up.
Optimus Prime: Autobots, transform and roll out.
[Once they've gone, Thomas turns to his friends]
Thomas: I still have a lot to learn about my past.
Arcee: Megatron had a back-up plan.
Megatron: I've had enough of your interference, Optimus and Twilight.
Optimus Prime: You know we're going to stop you, Megatron.
Megatron: I know you're gonna try.
Twilight Sparkle: You will be defeated Megatron.
Megatron: You two are going to regret interfering with my plan.
Bulkhead: [through comm-link] Optimus. Twilight. Something's wrong with the meteorite.
[As Optimus Prime and Twilight Sparkle gain the upper hand on Megatron, the Dark Energon meteor they're all standing on begins to shake and split open. Optimus Prime and Twilight stare into the inside of the meteor...and two red eyes stare back and the meteor explodes. As everyone falls back down to Equestria, a giant Cybertronian half buried in the Dark Energon meteor follows]
