-A Few Hours Ago—

-Supply Deck-

The Klaxons were grating on his audios, Prowl noted as he spied several bots coming from both directions, guns drawn and ready to fire. He growled, flaring his wings, his back plating on his shoulders splitting and forming his rocket launchers, he let his energon blades slide free with a deep threatening rumble.

Next to him Optimus had flicked forward his battle mask, small interlocking panels sliding from the sides of the mechs face to join at the front shielding mouth and olfactory sensors from view, a large almost cannon like gun appearing in a clenched fist, a heated energon sword sliding out from the mechs wrist with a sharp screech.

Mirage had disappeared as soon as he had spotted the approaching mechs slyly slipping an energon knife from his subspace as he vanished. Jazz dropped to one knee and aimed his EMP cannon, the muzzle crackling with blue magnetic energy, at the other end of the corridor as mechs came from both ends of the corridor.

Mirage crouched next to Jazz waiting for his Superiors signal to mingle into the crowd of mechs that had stopped short of them and cause some chaos.

A Large mech approached them from Prowl's side, red, blue and silver his hands up and showing that he had no weapons.

Optimus frowned behind his mask looking down to Prowl who offered his leader a confident trill making sure that both Primes knew that he would fire at the slightest threat to his flame decorated leader. The Prime gave a whistle of appreciation before dropping his mask and sub-spacing his gun, his sword retreating back into his wrist plating.

Both Leader's mechs tensed as the boxier leader spoke first

"I am Optimus Prime, Who are you?"

Prowl's golden optics brightened in surprise as Jazz gave a disbelieving glance over his shoulder; Mirage flickering into view in his surprise still crouched beside his superior, energon knife glowing his grasp.

Their own Optimus cleared his vocaliser with static, flickering through various languages before settling on English

"I am Optimus Prime"

The bots of the orange coloured ship suddenly laughed; Prowl growled scrapping his swords against the floor in defence of his leader who barely batted an optic cover at the response.

"My apologies for intruding, it seems Wheeljack had a mishap in his lab and we have somehow ended up here. Prowl" Optimus said glancing to his SIC "Stand down"

Prowl gave a grudging mutter before he folded his rocket launchers away and sheathed his blades whistling to Jazz and Mirage who also sheathed or transformed their weapons back into their frames. "We will not attack" Optimus guaranteed "We only fire in defence, unless you are a Decepticon of course."

"Who are you all?" asked a boxy rust red mech as the three mechs that hadn't spoken came to stand beside their leader.

"As you know, I am Optimus Prime" the sharper looking Optimus said before introducing his mechs "This is my SIC and Head Tactical Officer, designation Prowl"

Prowl gave the gathered boxy mechs a scrutinising glance, clearly still weary of them all, though he did take an interest in the shocked reaction of a black and white doorwinged mech just behind the other Optimus.

"My TIC and Head of Special Operations, designation Jazz"

"What's crackin'?" the silver mech grinned with a wave of a four fingered servo "This looks like a cool place to kick it"

In response he got a casual smack over the back of the helm with one of Prowl's doorwings.

"And one of Jazz's subordinates, designation Mirage" Optimus chuckled shaking his helm in amusement

The blue and white noble merely gave a soft hum before fading from sight like a ghost.

"Not to be rude" Prowl suddenly spoke up from where he was quietly whispering with Jazz about unnecessary showing off "But where are we?"

-Present-

-Red Alert's Security Room-

The smallest of the four mechs, Jazz, was crawling along the roof again, Red Alert noted as he saw a shadow moving towards his camera along the floor of the Training Pitch thank Primus our own Jazz can't do that he thought. He wearily watched the screen as the silver mech gave him a cheeky grin in the lens before scurrying off in the direction of his friends in the training room where their guests were currently loitering for a bit of privacy.

Red Alert hadn't known any of their names until after the standoff in the corridors of the Storage Deck, all of them now speaking to each other in a rumbling language, which he presumed was their version of Cybertronian, mostly compromised of low clicks, whirls and sharp whistles. Jazz was trying to teach them their version of Cybertronian as they had enquired about some of their history, all four favouring to puzzle over one screen together, clicking, chirping and in some cases they, mainly the silver Jazz, would laugh in low harmonics. So far even as the silver Jazz returned back, they were still on page one after two hours of surveillance.

-Training Room-

"I can't read this" Optimus declared his blue and flame decorated frame glinting in the Training Room's lighting as he gave his data-pad to Prowl who offered him a long suffering look in return "What?" the faction leader shrugged

"He's right" Prowl rumbled curiously examining the data-pad "Why aren't the words moving randomly around the screen? They're all in a freaky straight line"

Jazz laughed as Mirage snorted his amusement.

"Well I for one am going to solve this problem" Prowl said in frustration, his attention span wavering over the non-moving Cybertronian symbols on the screen. He got up from his sitting position on the floor and fluttered his doorwings in a casual stretch.

"I'm coming too, Prowler!" Jazz called trotting behind the SIC as they made their way to the Rec-Room, both scanning their surroundings and going where the noise took them.

"Aww look at him! He's so cute!" his mate cooed running forward separating a crowd of mechs with startled squawks, resulting in some spilt energon and poked a sharp exploratory digit on one of the stubby sensory horns of the ARK's Jazz "Though I gotta say mech, my audio horns are way better."

"Jazz, he's you" the Prowl with golden optics said rolling his optics and following his mate over with a resigned sigh.

"Which makes him all the cuter don't you think, Prowl?" Jazz grinned hugging his counterpart as Prowl offered him a long suffering groan.

"Can't breathe!" the ARK's Jazz gasped suddenly getting released as the silver version of himself giggled and started poking at his energon cube

"Prowl! Look! It's pink!"

"Thank you, for that brilliant but obvious observation Jazz" Prowl sighed though even he couldn't resist scanning the cube with a thinly veiled interest as Jazz once again rounded on his black and white counterpart who was looking vaguely disturbed that the silver mech who shared his name had a very short attention span.

"Isn't having a different dimension you walking around great?" the silver Jazz grinned hugging his counterpart again in excitement "We can swap mechly stories!"

"Forgive my mate" the golden opticked Prowl said grabbing one set of the three spiky audio horns on either side of his lover's helm and dragging him off of the TIC of the ARK crew "He's still not all right in the helm after Optimus fell on him"

"I said I was sorry" the flame decorated Optimus replied as he trailed in with a weary, visible Mirage who was getting chatted to by a green boxy mech who had introduced himself as Hound. "Anyway I'm sure you'll be able to fix him later Prowl."

"Of course" the golden opticked mech smiled slyly patting his bondmate on the helm who gave a pleased purr.

"Man, that's trippy" the black and white Jazz said shaking his head and turning back to his energon and to his conversation with the ARK's Prowl who had just entered a staring match with the golden optic baring Prowl, tension pouring into the air in droves as both tactical officers tried to stare each other down.

Suddenly alarms and klaxons went off, startling the four newer mechs as the ARK crew scrambled leaving half empty energon cubes and conversations midsentence.

"I wonder if they are in a hurry" Mirage deadpanned as he watched a cube rock on the table, the Rec-Room suddenly empty apart from the Dimension travellers.

"What's going on?" Prowl asked as they peered around the door of the Rec-Room towards the entrance of the ARK

The ARK suddenly rocked; the walls and floors vibrating as a thunderous boom crackled through the air from outside, followed by a sharper, closer cannon going off.

"Primus and all his Avatars" Prowl cursed as his battle programming shot online, throwing up his rocket launchers and his blades forming out of his forearms, the gauntlet like armour thinning as the blades shot forward and snapped into place.

Jazz's magnets in his servos crackled into life, accidently magnetising himself to the roof with a yelp. Mirage snickered as he re-faded into view, laughing at their Prime whose cannon had suddenly blown an impressive hole in the wall, molten orange metal dripping and forming a puddle on the floor.

"Come on" Optimus growled, still a bit jumpy from his fright, stalking down the hall with a snickering Mirage as Prowl managed to pry his mate from the roof with a good yank to a pede once he had convinced his programming that there was no immediate danger. "I sense a battle"
