This is how The Mane Six and Autobots reunite goes in My Little Pony Transformers: Age of Extinction.
[Optimus is driving in his rusty 1973 Marmon semi cab-over truck mode with the Mane Six standing beside him]
Optimus Prime: (voice) Calling all Autobots. Calling all Autobots.
[As Optimus is driving, a white Western Star 5700 Custom semi-truck passes by and Optimus scans it and changes into it in his color]
[Jazz, Ratchet, Ironhide, Bumblebee, Major Malfunction, Sideswipe, Crosshairs, and Drift are driving through the desert in vehicle mode. Hound sees Optimus in truck mode]
Hound: Oh yeah. Oh yeah! He's back! He's alive! [fires his gun in the air] Optimus is here!
Drift: At last, there's hope after all.
[Drift jumps off a cliff and transforms to helicopter mode and flies to the meeting point]
[Optimus drives up and the Autobots transform to robot mode and see their friends]
Crosshairs: Ha ha yes. Mr. Leader of the Free Galaxy's back. I knew you'd make it. I never doubted.
[Drift transforms to robot mode and lands next to Crosshairs]
Drift: We got your warning. We've been waiting.
Hound: Oh yeah, boom time. We got the gang back together.
[Bumblebee transforms from his black and yellow 1967 Chevrolet Camara vehicle mode to robot mode]
Rainbow Dash: Ironhide!
Ironhide: Rainbow Dash!
[Rainbow Dash and Ironhide share a fist bump]
Rainbow Dash: Miss me, tough guy?
Ironhide: I sure did.
Pinkie Pie: Jazz!
Jazz: Pinkie Pie!
[Pinkie Pie and Jazz share a hug]
Pinkie Pie: Was it lonely while I wasn't around?
[Rarity and Bumblebee hug]
Rarity: It is good to see you again, darling.
Bumblebee: To that, Rarity, I have to agree.
[Applejack and Sideswipe bump fists]
Applejack: How you holdin' up, tough guy?
[Fluttershy and Ratchet imitate an explosion]
Fluttershy: Glad we're back together.
[Optimus transforms to robot mode and looks at Twilight]
Twilight Sparkle: Long time, no see, big fella.
Optimus Prime: Long time, no see to you too.
Twilight Sparkle: We have so much to talk about.
Optimus Prime: We do indeed.
[Malfunction, Nighlock, and Sombra ride up]
Optimus Prime: The Cybertronians were asked to play by Equestria's rules. Well, the rules have just changed.
Hound: Mercenaries, bunch of backstabbing weasels.
Drift: Hound, find your inner compass. Loyalty is but a flower in the winds of fear and temptation.
Hound: What are you saying?
Drift: It’s a haiku.
Hound: Cut the stuff before I drop a grenade down your throat!
Drift: [draws a sword] Try it, you'll be dead!
Hound: Oh please pull it. Please do it.
Bumblebee: You know what just save us so much time.
Crosshairs: Well raise your hand if you're thouroughly disenchanted with our pleasant little Equestrian vacation. So who are the newbies?
Twilight Sparkle: Who are you and the other two?
Optimus Prime: Girls this is Hound, Drift, and Crosshairs.
[Later at night]
Optimus Prime: So there's been no signs of any others?
Drift: We're all that's left.
Crosshairs: They're picking us off one by one.
Hound: We’re the pathetic dirty ninesome. And you make ten.
Major Malfunction: Me, Anthony, and Sombra were unable to rescue Leadfoot, and we haven't found the others.
Rainbow Dash: Well, once again, we're on the run from the government. Only this time, the Canterlot Warriors have been declared outlaws.
Twilight Sparkle: Well for the record, I'm hiding out with Optimus.
Drift: Sensei, with your fate unknown, Bumblebee has held command. Despite his complete and total lack of anything resembling warrior discipline. He's like a child.
Bumblebee: This child is about to beat you up.
Drift: He brings us shame.
Optimus Prime: [looks at Twilight then to the Autobots, Nighlock, and Sombra (who is watching cat videos)] Autobots, Lockdown is hunting us and equines are helping. We need to know why.
[At that moment, Malfunction's minicon, Minibot, comes out]
Minibot: Listen, Prime, I may not know why. But I know who.
[He activates a hologram which shows how Tartarus Wind attempted to kill Ratchet before he was rescued by Malfunction, Nighlock, and Sombra]
Minibot: I captured this feed prior to leaving with the boss to meet with the other Bots here in Botswana. The attack on Ratchet.
[Optimus looks at Ratchet gravely, but his comrade doesn't look back]
Minibot: It's in pieces but watch what happens here.
[He then shows them the attack on Leadfoot]
Leadfoot: [on video] No! I'm an Autobot!
Hound: [sadly] Oh, that's Leadfoot.
Minibot: They ripped him apart.
Hound: [sadly places his helmet on his chest] Savages.
[Ironhide places his hand on the soldier's shoulders]
Minibot: And later, this truck comes to haul him off. FPI. Fancy Pants Industries. Defense, aerospace, government contracts. They even designed the drone I can disguise as.
Rainbow Dash: So these mercenaries just hunt you down and haul you off to Fancy Pants?
Rarity: Ugh! Of all the things Celestia would allow to happen without some intervention!
Minibot: The company is headquartered in Manehattan. That could be where they were taken.
Hound: No way to get inside without a battle.
Major Malfunction: Hound's right. They've had the worst experience with our kind, so if they see us, there won't be an escape.
Sombra: [in spanish] [translates to: "Well what if you had some organic help?"]
Pinkie Pie: Yeah, what she said. What if you had our help?
Rarity: We're helping them into a highly guarded city now?
Nighlock: Rarity, we're all targets until we can get our life back.
Optimus Prime: Autobots, I swore never to harm Equestrians.
Hound: Big mistake.
Major Malfunction: [pops his neck left and right] [growls like a tiger]
Optimus Prime: But when me and Twilight find out who's behind this, he's going to die.
Hound and Ironhide: Hoo-ahh!
[They drive off]
[They arrive in Manehattan as we see FPI headquarters]
Nighlock: There's a full-on manhunt out for us, so we have some new rules. Anyone who has a badge, they're not our allies or our friends. So we must divide and conquer. [to Rarity and Applejack] I'm placing you two in charge of stealing food and the essentials, nothing more. Manehattan FPI headquarters is like a fortress. Me and Twilight are gonna find a way into their top secret military wing. Find something to blackmail this company, the government, and Celestia (as much as I hate to do it). But no matter the cost, we're gonna fight to get our freedom back.
