This is how The Autobots return in My Little Pony Transformers: Dark of the Moon.

[The Mane Six, Moon Assault, and other former members of PHOENIX travel through Manehatten while they look at all the damage done]

[They get out of the vehicles]

[A few jets fly overhead, only to be shot down by Decepticon fighter ships]

Ex-PHOENIX soldier: We're going in there?

Moon Assault: We're not going in there. It's too dangerous.

Twilight Sparkle: Me and the girls will go in.

Moon Assault: I can't let you do that.

Rainbow Dash: Our sisters are in there.

Moon Assault: I can't let you girls get killed.

Rarity: We aren't giving up.

Moon Assault: Look at this place. It's over. I'm sorry, but it's over.

[The Mane 6 look down in sadness]

[Suddenly, a Decepticon fighter ship attacks, killing a few innocents]

Ex-PHOENIX Soldier: Look out!

[Then two blasts knock it out of the sky]

[We see Optimus come up, blaster in hand as he cocks it]

Optimus Prime: We will kill them all.

[Leadfoot, Roadbuster, and Topspin come up to the ship as a Decepticon tries to get out]

Leadfoot: Wreckers, kill it!

[They do so]

Roadbuster: This is going to hurt a lot.

[They tear him apart]

Optimus Prime: Your leaders will now understand. Decepticons will never leave your planet alone. And we needed them to believe we had gone. For today, in the name of freedom, we take the battle to them!

[The Mane Six, Moon Assault, and other former members of PHOENIX see Jazz, Ratchet, Ironhide, Bumblebee, Sideswipe, Dino, and Que arrive as Malfunction arrives in Sabre-Toothed Tiger mode with a human in armor and a girl with cybernetics]

Twilight Sparkle: We saw your ship blow up.

Roadbuster: We weren't in the ship! We designed the thing, didn't we?

[Malfunction transforms to robot mode, while the two humans hop off of him]

Leadfoot: We were hidden in the first booster rocket. We ain't going nowhere.

[Applejack finally notices the two human figures]

Applejack: Okay, who are those two?

[The ponies turn to the newcomers]

Major Malfunction: These are two of my students, Commander Tavary aka Nighlock, and Sombra.

Rainbow Dash: Like King Sombra?

Sombra: Could he do this?

[And as she reaches her hand out, a holographic keyboard appeared out of nowhere and deactivated Moon Assault's gun before reactivating it]

Brains: Yeah, no one's exiling us.

Wheelie: We're here to the end of the line.

Major Malfunction: [points at them] I like these two.

Optimus Prime: They're surrounding the city to make a fortress, so that no one can see what they're up to.

Nighlock: Then we scout ahead and find a weakness.

Twilight Sparkle: That's very wise.

Optimus Prime:

Twilight Sparkle:
