A Dinobot in Equestria

The ride back to Ponyville was, for a lack of better words, excruciatingly exhausting. Grimlock had to sit through yet another twenty four-hour long lecture about the strenuous amount of work it takes to precisely layer a cupcake with frosting while utilizing the utmost focus and care. At the break of moonlight, the train had finally slowed down to a halt in front of the Ponyville train station.

"..... And then you have to make sure the amount of frosting is juuuuuuuust right, or you'll have an overdose of frosting! You don't want to have too much frosting on your cupcake, do you? And then we move on to the sprin- Oh, look! We're home." Pinkie said, getting Grimlock's attention.

"Finally!" Grimlock said, almost leaping out of the train cabin as he stepped onto the wooden platform. Twilight and the others followed suit as they departed from the train with haste. Grimlock had taken a couple of steps into the town when he noticed a small shiny object on the dirt ground just behind a couple of houses. Grimlock walked over to inspect the object, kneeling and picking it up in his digits. The object in question was metallic in nature, sporting a lime green color. Grimlock glanced at the ground, noticing a trail of tire tracks leading away from the town. Twilight and the others approached Grimlock, taking notice of the green piece of metal in his servo.

"My, what a strange mineral that is. If I'm not mistaken, that must be a foreign metal composite of sorts. It could use a little less of that lime-green coloring, don't you think?" Rarity stated. Grimlock narrowed his visor as he just stared at the horizon.

"Stay here." Grimlock suddenly growled, walking away from Ponyville as he began following the tracks.

"Where are you going? Grimlock, come back! You can't just walk off!" Twilight exclaimed, running after the Dinobot. Grimlock turned to face the alicorn with a glare.

"Are you deaf? I said stay here!"

"Why? What's gotten you so worried all of a sudden? Is there something out there that you don't want us to see?" Twilight asked.

"Ah reckon Grimlock's spooked by something." Applejack said, looking at Twilight before approaching the Dinobot.

"What? No! I don't get spooked!" Grimlock yelled.

"You're acting strange, Grimlock. It's okay to admit if you're scared. You can tell us." Fluttershy said in a sweet tone.

"Son of a... Grrr, fine! You wanna know? You and, by extension, your town is in danger right now. This chunk of metal belongs to another guy that's like me. I am what you call a Cybertronian, and as it turns out, I wasn't the only Cybertronian to crash land on your world. These Cybertronians are called Decepticons and they're evil aftholes who like hurting people and destroying stuff for no reason. I have to go and make sure they don't set their sights on your stupid little town. Listen to me, this isn't your problem to deal with so stay here until I come back! I MEAN IT!" Grimlock said, running off as he began to follow the trail.

"Wait, did he just say we're in danger?!" Rarity gasped.

"W-What if those m-m-mean r-r-robots Grimlock t-t-talked about l-l-look r-really s-s-s-scary...?" Fluttershy stammered, cowering underneath her mane.

"Whether it's our problem or not, we're not going to stand idle and wait for any metal things to come to attack Ponyville! Come on, girls!" Twilight said, running after Grimlock along with the rest of the Main Six.

"Hey, wait for me!" Spike exclaimed, running after the six ponies in a hurry.

Grimlock unsheathed his massive sword and a large orange shield, taking cover behind a large boulder after hearing the ominous sound of drills burrowing into the ground. The trail he had been following led to an open plateau, where only a few trees and little grass can be found. Grimlock took a peek from his cover, narrowing his visor. Two Decepticons, both sharing a green and purple color scheme, stood tall and watched as a squadron of miner-class Vehicons worked hard to dig deep into the rocky ground. The left-hand Decepticon sported a boxy charcoal-grey head, a red visor that replaced standard optics, and a silver mouth-guard that covered most of his faceplate. Two halves of a front-mounted blade that formed the upper section of the Decepticon's vehicle mode formed the upper portion of his rotator cups, while two sets of rough-edged tires jutted out from the back of the Decepticon's arms and legs. His partner was slightly taller than he is, bearing two normal red optics and a standard faceplate. The majority of his arms and legs consisted of conveyor tracks intertwining with a metal outer frame. The Decepticon sported a large elongated pole with a curved hook at the end that jutted out of his backside, earning the name "Hook".

"Move it, you worthless hunks of scrap! Shockwave wants three cartloads of Energon back to his lab by sunrise! Unless you wanna be taken offline and used for spare parts, I highly suggest you dig faster!" The shorter Decepticon, Scrapper, yelled as he supervised the motley crew of miners. Grimlock slinked back behind cover, his mind racing faster than a speeding train.

"Shockwave is here...?! If he's here and Scrapper's here then that means that one-eyed glitch-head has another Space Bridge running somewhere on this planet...!" Grimlock spoke to himself, standing up. Grimlock tightened his grip on the hilt of his sword as he charged forward, exploding in a terrifying burst of speed as he rushed the two Decepticons from behind. Right as Scrapper and Hook turned around, Grimlock bashed the two Constructicons with his shield, knocking them off their pedes and sending them crashing into the ground.

"AGH!" Hook and Scrapper yelled out as they crashed into the rocky floor. Groaning with pain, the two Decepticons groggily sat up before gazing at their assaulter.

"What the...? Grimlock?!" Scrapper exclaimed, whipping out a laser pistol.

"You're supposed to be offline!" Hook yelled with an almost fearful tone in his voice.

"Does this look offline to you, glitch-head?" Grimlock retorted, raising his sword to strike down the two Constructicons.

"VEHICONS, OPEN FIRE!" Scrapper yelled. Almost immediately, the squadron of Vehicons accompanying Scrapper and Hook unsheathed their plasma cannons and turned towards Grimlock, opening fire on him with a barrage of neon-red bullets. Grimlock backed up as he was forced to block the bullets with his shield, growling in frustration as his anger began to rise. Grimlock charged at a squadron of Vehicons, bashing them with his shield before impaling a couple of the miners in the chest plates with his sword. Grimlock grabbed another Vehicon by its legs and swung him around like a bat, bludgeoning several more Vehicons with his makeshift weapon. A neon red Energon-empowered bullet striking Grimlock in the backside got his attention, forcing the Dinobot to turn around and face the two Constructicons.

"Where's the rest of your squad, Scrapper? I thought they follow you everywhere." Grimlock asked with a snarl.

"Funny, I was thinkin' of asking you the same thing." Scrapper spat before unsheathing a sword from his transistor segment and charging at Grimlock.

"Twilight, Ah'm not sure gettin' ourselves smack-dab in the middle of a big ol' robot fight is the brightest idea n' all. We're not exactly big like Grimlock." Applejack said.

"O-Or p-p-physically v-very s-strong...." Fluttershy nervously added.

"You both are right, but we can't afford to sit around and do nothing if one of those robots Grimlock mentioned decide to target Ponyville. Besides, I will make sure none of us get h-"

Right before Twilight could finish her statement, a chunk of broken metal flew right over the mares, forcing them to duck while putting the mares in a collective state of panic. After a moment, the sound of angry yelling and the screech of twisting metal quickly caught the Main 6's attention.

"RAAAAAAAAARRRRGGHH!!!!" Grimlock roared as he furiously bludgeoned Scrapper with one of the Vehicons, bashing the Constructicon with the Vehicon several times before knocking him over with a hard uppercut. Hook fired his Energon pistol at Grimlock while charging at the Dinobot, yelping in surprise as Grimlock simply grabbed the Decepticon by the arm and smashing him into the ground before stomping on his faceplate with his ped. Scrapper leaped into the air, landing a powerful flying kick on the Dinobot's faceplate and knocking him down.

"I honestly expected better from you, Grimlock. You're supposed to be the most dangerous Autobot ever forged on Cybertron. Where's the bloodthirsty Decepticon-killing monster everyone's always talking about?" Scrapper taunted.

"He's right here!" Grimlock yelled, leaping off the ground and tackling Scrapper. Grimlock began punching Scrapper in the faceplate and chest before hoisting Scrapper in the air and throwing him into a rather large tree. Grimlock charged at Scrapper yet again, only to have the Constructicon weave out of the way and punch the tree instead. The sheer force of Grimlock's punch shattered the base of the tree, causing it to topple over right on the Dinobot and pin him on the ground.

"You've gone soft, Grimlock. I'm definitely gonna miss our fun little reunions. Regardless, I'm gonna enjoy bringing your head to Shockwave." Scrapper said, aiming his pistol right at Grimlock's faceplate. A bright magenta beam consisting of pure magic struck Scrapper in the back of his head, throwing the Decepticon off balance for a moment.

"OW! WHAT THE FRAG WAS THAT?!" Scrapper yelled as he turned around to witness Twilight swooping in and firing a much larger magic beam at the Constructicon. Scrapper yelled out in pain as he was sent flying into the ground.

"Applejack, Rarity, get that tree off Grimlock!" Twilight ordered. Applejack grabbed a large rope from a satchel she was carrying, wrapping it around the base of the tree while Rarity enveloped the upper half with her magic.

"What the hell are you doing here?! I told you to stay in the town!" Grimlock yelled.

"How rude! We're trying to save you! It wouldn't kill you to practice some gratitude for once!" Rarity scolded.

"We can just leave ya here to rust if yer so keen on fightin' these here overgrown varmints alone." Applejack retorted. "Quit yer yappin' and start pushing."

Grimlock just grumbled to himself as he grabbed hold of the tree, using all of his strength to lift the tree with Applejack's and Rarity's help. After a moment, Grimlock finally shoved the tree off his body and threw it aside. At that moment, Hook lifted his ped off the ground in an attempt to crush the two equines underfoot.

"MOVE IT!!" Grimlock yelled, grabbing Applejack and Rarity in his servos and rolling to the side right as Hook stomped on the ground. With an angry snarl, Grimlock stood up with both ponies still in his left servo. Hook charged at Grimlock once more, unsheathing a large steel sword from a holster attached to his waistline.

"HE HAS A SWORD!" Rarity yelled.

"So do I!" Grimlock retorted as he unsheathed his crimson blade and countered Hook's downward blow with a perfectly timed vertically-aligned parry. Grimlock growled, kicking Hook in the codpiece with so much force, the Constructicon screamed in a hilariously high-pitched voice before clutching his groin area and doubling over in pain. Using the opportunity, Grimlock knee'd Hook in the faceplate with enough strength to propel him backward before punching the Constructicon in the faceplate with his free right hand, knocking a very dazed Hook onto the ground. Grimlock placed Applejack and Rarity on the ground before charging towards Scrapper with a loud roar. Grimlock grabbed hold of Scrapper by his left arm, twisting it backward before elbowing Scrapper in the faceplate with immense force. Scrapper yelled in pain before unholstering his own blaster, aiming it point-blank at Grimlock's faceplate. Grimlock grabbed hold of Scrapper's blaster and forcibly wrenched it from his grasp before opening fire right at the Constructicon's face. Scrapper screamed with immense pain as most of the right-side of his faceplate was completely blown away by the explosive force of the bullet.

"AAAAAAAAAAGGGGH!! M... MY... AAAAUUUGH...! YOU SON OF A... AUGH!" Scrapper blurted out as he clutched his horrifically mangled face. Bits of metal, wire, and part of his visor fell out the side of Scrapper's face while Energon spilled out of the massive wound. Hook jumped up and rushed over to his wounded commander, taking the Constructicon by the arm and running off.

"You'll regret that, Autobot! You all will!" Hook yelled as he ran off with the wounded Scrapper in tow. Grimlock just growled to himself as he watched the two Constructicons flee for their sparks.

"That was awesome! You really messed that guy up!" Rainbow exclaimed with a grin. Grimlock turned to look at the cyan pegasus with a almost satisfied expression on his faceplate.

"You're damn right I did. Alright, we're done here." Grimlock said as he headed towards Ponyville with the Main Six following close behind.
