This is how Applejack vs. Hardshell goes in Sparkling Problems.
[Applejack walks through a corridor with Sparkling Bulkhead and Wheeljack on her back]
Applejack: Don't worry. We're almost out.
[Applejack hears something]
Applejack: [gasps] Hardshell.
[She peeks through a door and sees Starscream and Hardshell talking with each other]
Starscream: Hardshell, what do you have to report?
Hardshell: Yes. The ponies somehow snuck in. I believe they now seek to free their guardians from their miniture size.
Applejack: [to herself, whisper] I knew they were working together.
Starscream: So, the Equines have come to turn their Autobot friends back to normal. Your brethren and I will make certain that they do not escape. In the meantime, go find the orange Earth Pony and bring her to me.
Hardshell: Yes, Lord Starscream.
[Starscream and Hardshell set off to find the ponies while Applejack gallops off]
Applejack: Stay close you guys.
[Applejack runs into Hardshell, hanging upside down on the ceiling in robot mode]
Hardshell: Hello, my little one.
[Hardshell climbs down from the ceiling]
Applejack: Hardshell.
Hardshell: Applejack.
Applejack: Been a long time.
Hardshell: Too long.
Applejack: What do you want?
Hardshell: I'd like a challenge.
[Hardshell throws his fist down and Applejack runs off]
Hardshell: You won't escape me!
[Hardshell goes after Applejack and the two Sparkling Wreckers]
Hardshell: Where is the fight you promised me, my little Earth Pony?
[Applejack hides in a storage room]
Applejack: [whisper] You two should get outta here. It's not safe.
[Hardshell finds Applejack and punches his fist through the door and tears it off its hinges and throws it away]
Hardshell: Your friends won't help you. You're stuck with me.
[Hardshell advances on Applejack, who starts to gallop towards him as the two Sparkling Wreckers escape through an air vent]
Applejack: [kicks Hardshell]
Hardshell: Learned a few Wrecker tricks from your favorite Wrecker, my dear Applejack?
Applejack: Yep.
Hardshell: Well, you are impressive.
Applejack: Leave it to Starscream to send an Insecticon to do his dirty work.
Hardshell: You know a thing or two about dirty work yourself, Wielder of the Element of Honesty.
Applejack: Yeah.
Hardshell: Well, then, let's see you do a few more Wrecker tricks.
[Hardshell fights her]
Applejack: How'd you know I wield the Element of Honesty?
Hardshell: I know
[Hardshell holds Applejack upside down by her tail]
Hardshell: Another Wrecker to add to my list and collection of Wreckers I defeated. Lord Starscream has trapped your precious friends with my Insecticon brethren. When I'm finished with you, they're next.
Applejack: Ah ain't gonna let that happen. You'll just lose again.
Hardshell: Not this time.
[Meanwhile]
Twilight Sparkle: Insecticons.
Rainbow Dash: What do we do now?
Fluttershy: I don't know.
Rarity: But we'd better think fast.
Pinkie Pie: We need find the other Autobots.
Starlight Glimmer: Applejack probably has Wheeljack and Bulkhead in a safe place.
Trixie: She always knows a good safe hiding place.
Thorax: That is one cunning Earth Pony.
Discord: This seems like one of those moments where we need a plan.
[Starscream arrives]
Starscream: Insecticons, take these ponies to the same place your leader put that Earth Pony.
Insecticons: Yes, Lord Starscream.
[The Insecticons leave with the ponies dangling by their tails in their hands, but Starlight uses a teleportation spell and teleports herself, Trixie, Thorax, and Discord away]
Starscream: [growls] Find those two unicorns, that former spirit of Chaos, and that Changeling traitor.
Insecticons: Yes, Lord Starscream.
