Everyone listened carefully during Prime's speech about Cybertron's history and their past throughout the long rivalry between the Autobots and Decepticons. The girls stood completely silent and horrified at the end of his explanation, it was hard for them to comprehend everything they'd been told just a moment ago. 

"All those terrible things that happened to you, for such a long time..." Sunset raised her head and sorrowfully looked at Optimus, sympathy could be seen in her eyes, "I'm so sorry..."

The leader bent down to the girl, "I truly appreciate your concerns, Miss Shimmer. However, you do not need to apologize for anything that has happened. You and your world are now in great danger because of us-- because of me." he corrected himself, closing his optics in guilt, "Once again innocent lives have been brought into our consequences, how could I let this happen?"

"It's not your fault Optimus, you didn't know and neither did all of you. Don't blame yourself for this and please, call me Sunset."

"Very well." nodded the Prime.

"Don't worry about it kiddo, it's finally over, although some 'Cons think otherwise." Bulkhead added.

Fluttershy nervously stepped forward, "Um, if you don't mind me asking, but-- how exactly did you discover the existence of our planet?"

"Well, the most dangerous and threatening prisoners on Cybertron, somehow managed to escape and now are on the loose. You were almost captured by a group of troops who serve as the foot soldiers of the Decepticons, Vehicons. Guess they've been behind all of this but we have no idea how they got a functional Spacebridge in the first place." assumed the green giant.

"Due to their constant activity here on Earth, we were capable of investigating further." Arcee kept on going.

*beginning of flashback*

In the middle of a mountainous region that included vast semiarid grasslands and sandy alkali deserts, Vehicons troops could be seen clearly within the entire lifelessness around them. Three giant figures though were observing from a large rocky hill above, keeping themselves perfectly hidden so as not to get spotted by their enemies.

Arcee put a digit on her audio receptor while watching how the troopers were pushing empty carts through a portal, "Got them."

::Be careful, remember that we are still not aware of what is on the other side of that bridge.:: Fixit warned through the communication system.

"We will keep in touch Fixit, once we enter, we are sending the coordinates to you, Bumblebee out." the mech finished and leaned down beside his teammates.

"Ready whenever you say, lieutenant." the femme notified.

"Me?" Bumblebee looked over her with a raised optical ridge, "Are you sure?"

"C'mon kid, you already got the hang of all the leadership stuff." Bulkhead affirmed.

Uncertainty roamed around the young Autobot's processor but Arcee could distinctly see his hesitation, "Hey," she gently placed a servo on his arm, distracting him from the insecure thoughts, "Don't worry, we will be right behind." she confirmed, "You got this."

Bumblebee smiled softly, his spirit lifting from his friends' support, "Thanks guys." he aimed his attention back at the foot soldiers, "Alright, this will be our only chance, so we have to be stealthy and quick." he cautioned, "As soon as the last 'Con starts going in, we rev up and roll out to that Groundbridge."

"Let's hope we don't bump into a whole army." wished Bulkhead.

"Prepare for the worst." Bumblebee alerted.

After a few more minutes of patient waiting, the penultimate Vehicon entered and went through the portal, it was the last one's turn to walk in. 

The moment he began pushing the only left cart, the young Autobot leader leaped, "Now!" he cried out and quickly transformed into his alt-mode along with his allies. Alas, when they increased their speed the Vehicon heard the sound of their loud upcoming engines and sturdy tires in the sand. When he spotted a motorbike with two automobiles approaching him, the faceless soldier instantly charged at them and switched on his comm-link.

"We have to stop him before he reports to the others!" Bumblebee exclaimed.

"Leave it to me." Arcee said and sped up. Before the Vehicon could blast her and contact his comrades, she transformed back into her robot form and jumped over him. Due to his late reaction, she was able to charge at him with her Energon blaster and shoot him down mid-air. Afterwards, she gained the form of a motorcycle again and landed flawlessly on the ground.

"Show off!" jokingly shouted Bulkhead from behind. Just in a split second, the bridge closed right after everyone entered inside. 

A few seconds later, they came out from the light before it vanished into thin air. The Autobots instinctively put on their breaks to examine the unknown area. They were relocated in the middle of a mountainous meadow, nothing else was surrounding them except the sight of the beautiful nature and the sound of the pleasant melody coming from the tiny chirping birds.

"Phew, no 'Cons." Bulkhead certified, all of them converted into their robot modes, the bright sun reflecting on their smooth armors.

Arcee decided to take a better look at the view. While gazing around, she spotted something that caught her optics in the distance, tracks of wheels were leading towards a civilization, "Hm, seems like we're close to some unknown city."

Bumblebee contacted the mini-con, "Okay Fixit, do you know where exactly we are?"

::Um-- lieutenant, according to the information that I was able to analyze, your location does not appear anywhere on the map.:: Fixit informed with a worried tone.

"What...?"

"Bee, what's wrong?" Arcee asked concernedly and moved closer to Bumblebee who had a perplexed expression on his face-plate.

"Everythin' alright?" additionally questioned Bulkhead.

And that's when we found out...

"This is not our Earth."

*end of flashback*

"We followed their tracks which were leading to already emptied mines, probably once stored with fresh energy resources. It appears they have found more than a few stockpiles on your planet and I am very sure they are considering more mining operations in order to claim every last piece of Energon for themselves." concluded the femme.

"Energon? You mean the fuel and life-blood of all Cybertronians? As far as I remember from what you mentioned earlier, it is extremely harmful to any other organic life form such as us humans, right?" Twilight recalled, readjusting her glasses.

Fixit came closer to her while holding a data-pad with his small digits, "You've remembered well, Twilight Sparkle! However, when we detected your coordinates, I couldn't help but notice, your planet contains ranks of a huge amount of yet another energy source that it is-- how do I say it? Inexplicable. Perhaps you may know what it is?" he gave the pad to the girl to take a look. 

The whole group gathered closer to see. The screen displayed words that were written in weird symbols, perhaps their Cybertronian language. Аlong with that, there was a chart which represented numerous long lines with very high percentages. The teens exchanged nervous glances at each other.

Could it be?

They were unsure if their assumption about the mysterious power was correct, but it was still very possible.

"Maybe it's our magic thingy? " Pinkie whispered to Rarity.

Arcee heard that clear enough and turned to her, "Wait-- magic?"

The pink girl froze and nervously chuckled, "Pfft, whaa? What about magic? I don't even know what magic is hehe..." she shrugged and gave an awkward smile, Rarity face-palmed at her poor pretense.

"You are hiding something, aren't ya?" questioned Sideswipe out of suspicion as he crossed his arms and leaned over one of the platforms.

"I am aware that you are still not capable of trusting us, which I fully understand, but please, we only wish to protect your world and keep you girls safe from our enemies. I give you my word." promised Optimus.

Sunset sighed, "Okay, this... may sound a little crazy but--"

"COMING THROUGH!"

Everyone almost jumped when they heard the shout from afar. They immediately spotted three vehicles coming in a hurry as if they were in a race. The very first car was an Indy 500 McLaren MP4-12C race car with double 7's on the sides, colored in yellow and blue, right behind him was a bright red Aston Martin, the inner parts and spokes of his wheels were painted in shiny gold, and the last one was a patrol vehicle with white and blue colors.

"Boys! Slow down!!" the police car cried out in a female voice.

Tactlessly, the blue-yellow one kept on driving too fast towards the whole group, "Watch out!" he warned, all humans and 'Bots quickly moved aside from the fast incoming vehicles. As the car began drifting to prevent itself from bumping into anyone, Ratchet impulsively raised one of his pedes and the car passed right underneath him, pulling up smoothly. A big cloud of dust came out from its wheels and the humans started coughing from it right after.

"HWAT IS THE MEANING OF THIS?!" the medic shouted at the automobile which in the meantime was transforming into its robot form, he was the same size as Ratchet, door wings attached on his back and two streaks of yellow on his head, "Smokescreen, explain yourself at once!" he demanded with an angry tone in his voice.

"Heh, sorry 'bout that Ratch, didn't see you are in front of me. Guess I was too distracted by beating up Mr. Perfect-Paint-Job here." the smiling mech pointed at the cherry red four-wheeler.

The Aston Martin gained the form of a shiny red 'Bot with red optics and had two white ear-like appendages, and a long pointy crest on top of his head that extended to his face, "Don't be so prideful, youngling. Next time I won't be so easy on you." he mocked back.

"Are you implying that you let me win?"

"You sound so surprised. Why of course, I did. Otherwise, you would be far behind me."

"Ha, yeah sure! You just don't want to admit that you lost to--!"

"Enough, both of you! Have you completely lost your senses?!" Ratchet furiously shoved them away from each other.

The patrol vehicle was a female, she had white and blue over her body, gray around her face, black in other parts of her armor, and a golden plate across her forehead. She had a bulkier body, plated armor bits around her chest and a very slim figure from her waist to her legs. 

Subsequently, she approached the arguing robots, "Tried to warn them sir, but then they even decided to go over the speed limit." the femme mentioned while glaring at the mechs.

"Oh, c'mon Strongarm, what is all this fuss about? Nobody saw us anyway!" pointed out Smokescreen.

"Actually, you've managed to drag the attention of several human drivers during your little competition. It looked as if the police were chasing two fleeing criminals!"

"Psht, you are no fun cadet." Sideswipe inserted.

"Don't get involved in this, punk." cautioned Strongarm.

Ratchet looked at the shinier red robot, "I assume you are the one responsible for this?" 

"Relax my dear friend, it was just a small race to brighten up the mood, you know? Nothing to be worried about." he reassured calmly and put a servo on his colleague's shoulder-pad.

"Still, you have to stop encouraging every 'Bot in your sight to participate in these nonsensical games of yours, Knock Out." he shoved him away, "I prefer not to take any risks and get into more trouble than we are right now!" he indicated the tiny girls behind him.

Pinkie waved at them with a bright smile, "Hiya!"

The new trio was standing in complete shock while staring at their small figures.

"Humans? Here?!" Strongarm took a step back, her optics widened from the unexpected sight.

"Uhh-- did we miss something while we were gone?" Smokescreen questioned nervously the rest of his teammates.

"Sideswipe! What part of 'stay in disguise' you didn't understand?!" scolded Strongarm.

The red mech was taken aback by the sudden outburst, "Got revealed one time in front of a human and now blame it all on me! Why not?!" he glared at her.

"It wasn't only him, Strongarm." Bumblebee explained while he quickly moved between the two of them, trying to prevent any upcoming and unnecessary fights, "It was all of us, we had no choice."

Knock Out, on the other hand, stepped towards the worried teenagers, "Ah, do not be frightened ladies, I mean no harm. Except of course, if you scratch my paint, then we will have a problem." he lowered himself and examined them one by one, "Hmm, your appearances seem slightly different than the fleshies who live here, how interesting. But I must admit, it makes it easier for me to tell you apart." then his optics focused on Rarity, her elegant style seemed to have caught his attention, "And you, my dear, are quite easy on the optic." he leaned closer to her.

A small smile appeared on her face as she politely waved off his flattering remark, "Oh, you are so kind darling, it's not every day I receive such compliments. May I add how astonished I am by that well-maintained job of yours, seems like you take very good care of it, do you not?"

The cherish red doctor's optics widened in wonderment, "Finally, someone has noticed! Do you know how hard it is to keep it in such a good shape? Honestly, some people don't appreciate the efforts I put into-"

"Ahem." Ratchet impatiently interrupted from behind.

"-this." Knock Out glanced at him and then back to the girl, "If you excuse me." he stood up and looked at the rest, "Alright then, I would very like to know how exactly you let the cat out of the bag this time." he smirked.

"A CAT? WHERE?!" Grimlock jumped out of terror and immediately hid behind Bumblebee, his body shivering in fright, hoping that any feline creature is not near him.

"There is no actual cat Grimlock, just a human expression." Bumblebee explained to him.

Suddenly, Spike came closer to the scared giant and spoke, "Whoa, didn't know big guys like you can get scared easily by something so harmless."

Everybot snapped their helms to the small talking canine and remained entirely motionless.

"HE TALKS?!" all of them confusingly shouted in unison.

Spike gave them a perplexed look, "Wha- are you kidding?! The talking dog is the most shocking thing here?!"

Twilight instantly went to grab him in her arms and let out an awkward chuckle, "Haha well, it's a long story really..."
