A/N: This just the scene of a crossover with TF:Prime with their Shattered Glass-verse. I'm not really a fan of Shattered Glass, but I had thought about this scene and I just wanted to write it down. Set during Beast Hunters.

The summery of the story going up to this scene is, Ratchet from the Mirrorverse travels to the Prime verse in hopes of taking the Matrix from Optimus. He kidnapped the real Rachet and portrayed as him for the three days that he was there. The Autobots did notice a different sudden change in his behavior and after witnessing him trying to experiment on one of their human friends they intervened and their Ratchet returned to confront his counterpart. However, the scuffle between them had made the other Autobots lose track of who was the real one. When Optimus started questioning them on certain events that could have brought out the real one, the Mirror-Ratchet had implanted a device in Prime-Ratchet to relay information, and block comm signals, to answer the questions correctly.

This is the scene that follows.

Hope you like it, enjoy.

Legend:

"Hi."- Talk

"YooHoo!"- Inner-Thought

*"Hello."* - Comm-link.

M.S.M.D

"This is bad," Jack tightened his grip on the catwalk rail as he and Miko anxiously watched the scene before them. "It's like Makeshift Déjà vu all over again."

Two Ratchets were sternly facing each other with folded arms, optics never falling away from the other, standing in the middle of the hanger, the other Autobots were on the side lines with blasters at the ready, but were hesitant on taking any action. Both Ratchets were exactly the same, and from the earlier trivia spat they had the same past major memories up until the three days before. Now, no one had any idea about how to tell them apart from the real one… to the sinister mirror self of their medic from another dimension.

Miko was bouncing on the balls of her feet at the nervous tension. Raf had taken shelter next to Agent Fowler, who looked at the scene with a deep frown. The boy was still shaken by Mirror-Ratchet's attempt at a 'checkup'.

"Well someone had better come up with something soon, these two are going to go at it like bears over a honeypot," the man whispered tightly.

Bulkhead, Smokescreen, and Bumblebee glanced at each other nervously, while Ultra Magnus and Arcee stood tense. Wheeljack was clenching and unclenching his sword handle.

Even Optimus Prime had to frown, his spark could feel his old friend, but with the presence of the other had made it difficult to point him out.

Meanwhile the still Ratchets were at war within their CPU's, Ratchet inwardly snarling as the other mocked him. (*)

"Face it, Medic. I'll win, and soon not only will I be rid of you, and the matrix in my possession, I think I'll take some of those humans as experiments," there was a twisted grin in his voice. "That little one would be a perfect pet."

Both Ratchets moved into a new stance in snarling fury, their knives transformed from their hands, making everyone tense and raised their weapons, however one only did it to keep up the act, the other was purely genuine.

"Over my sparkless husk, you sparkeater-reject!"

"That will be arranged, walking rust heap."

Jack bit his lip as he watched and heard the snarls from the medics, the sounds echoed softly in the hanger, but it felt deafening.

He blinked.

Wait… echo… deafening… If he's from there then… So he wouldn't have it! That's it!

"I don't know how much more of this I can take," Miko worriedly moaned at his side. She blinked at him when he grabbed her arm and whispered into her ear. Her eyes widen and she looks at him curiously. "Yeah they're here but I haven't used them much since Ultra McSarge came, why?"

"How fast and quietly can you set them up?" He spoke low as he glanced at the rising tense scene.

Miko just look at him with more confusion. "I can set them up fast but not very quietly, why? This isn't time for-"

"This is a perfect time for one since he wouldn't have an IT."

She face light up in shock at his smirk. She then gave a silent squeal, returned his evil smirk and whispered back. "Jack, you genius! How much?"

"Full Tilt."

The Asian girl rubbed her palms in excitement.

"One fast and 'quiet' set up, coming right up. You better warn the others." With that she took off to her section of the living area as quietly as possible. Fowler and Raf looked away from the near doc fight to watch her curiously, they were surprised when Jack came beside them and handed them a pair of headphones.

A look of realization came on Raf's face.

"Fowler can I use your phone, and put these on? You have 'Autobot conference call' on it right?"

"This is getting ridicules," rumbled Wheeljack as the medics started to circle each other. "I say we knock them both out. Then we can weasel out the fake."

"Won't that cause more problems?" asked Bulkhead also keeping his vocalizer low.

"Beep-whoo-bib!"

"Like that's any better!"

"We could have a 'grumpy' contest… what? The grumpiest Ratchet is ours right?"

"This isn't a joking matter, Smokescreen," scowled the wreaker commander.

"Just an idea."

Arcee felt the Wheeljack's idea sounded pretty good right now.

*"Arcee."*

Her optics blink at the sudden ping in her comm. It registered to Fowler, but Jack hushed voice came over. She noticed all the other Autobots, except the Ratchets, start at the summons as well.

*"Jack? Why are you calling through the conference call on Fowlers phone?"*

*"Everyone, don't react to this call, just stay quiet. Answer through the inner-comm."*

*"This isn't the time for pleasantry calls, Mr. Darby."*

*"What are you up to, Jackson?"* The Prime remained focused on the twin medics outwardly. His sensors found the young man with the phone on the other side of the hanger on the catwalk, his optics widen a fraction when he saw Miko mess with a familiar box shape.

*"Please trust me sir, everyone turn on your MSMD's."*

Only Ultra Magnus tilted his head in confusion.

*"And I thought Raf was the only genius,"* Wheeljack was glad he had his mask on, his grin would have been noticed by the feuding Ratchets.

*"Beep-bib-booop!"*

*"Got that right, wouldn't know what hit him!"* The rookie had too really keep his bouncing steps stone still.

*"That's my partner."*

*"I am… confused, what is an 'MSMD'?"*

*"Oh scrap, that's right you don't have one."*

*"Ultra Magnus, just turn your audial dampeners to their highest level,"* Optimus looked to the bewildered commander slightly, never giving away their plan to the two white mechs. *"And I would advise covering them as well."*

Still looking bewildered, Magnus did as told. He turned to the center stage as the Ratchets now had each other in a hand hold with one of their servos while their knives were trying to inch toward each other's necks. But it looked like one was starting to weaken, and he struggled to keep his form up. His CPU was fighting to ignore the boastful mocks.

"Oh, look you're getting tired. A clear sign of my supremacy. Fall and die!"

"Never!"

Jack looked keenly and found that now was the time. He looked over at Raf and Fowler, their headphones were on, check, he looked to the Arcee, she glanced at him and the gave a simple slight nod, MSMD's activated, check. He then looked to make sure Magnus was prepared at least, check, and now…

His own headphones were in place as he looked over and saw Miko behind her AMP, she positioned it within range of the feuding mechs, her guitar plugged in and she turned the volume dial to full volume. She got up into potion, her headphone secured head turned to him and she gave a thumbs up.

He looked back at the Ratchets and raised a hand.

Everyone waited on held breathes and/or intakes.

The pick was raised at the ready.

One Ratchet was struggling to keep one knee from falling, the other had a slight smirk of victory.

Jack threw his hand down. "Now!"

The pick fell.

"BWWWWWWWAAAAAAAOOOOOOONNNNNNNNNGGGGGG!"

The sound of the struck strings rang into the air. The hanger walls seemed to vibrate.

The humans, besides Miko, pressed their headphones over their ears.

The Autobots had a little grimace on their faceplates, save for Bulkhead and Wheeljack who had laughing smirks.

Ultra Magnus cringed greatly and fell on one knee as his audials screamed as if in pain. He grinded his dentras, he pressed his servos tightly to head helm, and his processor circuits felt they were splitting.

But he just had a mild reaction compared to the other.

"AAAAAAIIIEEEEEEEEGGGGGGGHHHHH!"

Both Ratchets had cringed at the sound and covered their audials as Miko played her music of loud harsh random cords, notes, and high octaves, a loud thump and crash came from the floor while…

"MIKO!" Ratchet uncovered his audials, MSMD activated, and scowled the still playing girl with fist on his hips. "This is not time to play your Primus… for… saken…"

He slowed his reprimand at the sudden realization and he turned to the floor.

"AAAAIIIIEEEGGHHH! WH-WHAT IS THIS HORRID NOICE!? IT'S AWFUL! MY CPU IS MELTING! PLEASE, MAKE IT STOP! PLEASE, PLEASE, MAKE IT STOP! AAAAIIIIEEEGGGHHH"

Mirror-Ratchet flailed on the concrete floor, his servos pressing so hard to his audials his helm sounded like it was being crushed. His face looked like he was about to face Unicron alone with an ice cream scooper.

Ratchet stared for a bit, then started to smile and laugh as he watched and turned back to the still playing girl. "Hahaha, wonderful, astounding music, crank it up!"

Miko grinned at him.

"NO!" This time Magnus had to reach out in slight plea, he cringed when he had to remove a servo to do so. "Please no more, I think I'm going into stasis lock!"

Ratchet continued to laugh as Jack motioned to Miko with his hand cutting across his neck. She played at least one more dramatic guitar riff and the sounds faded.

Leaving a still pleading, shaking heap of Mirror-Ratchet on the concrete.

Smokescreen came up with a pair of mag-cuffs and latched them on the wrists.

Mirror-Ratchet stared off into space until he slowly shook his head, but his audials were still ringing. He realized his was cuffed, but any angered resistance was foiled when he was faced with the point of Wheeljack's Sword, Prime's cannon, Bulkhead's Wreaking ball, and Bumblebee's and Arcee's blasters. And a whole Autobot squad of smirks.

He whimpered in defeat.

The right calibrations to the groundbridge were entered, the coordinates of the right dimension were logged in, and by Special Bulkhead Lob Delivery the mad doctor of the Mirrorverse was returned back to where he belonged and their weird nightmare had finally come to an end. Making doubly sure he'd never ever come back, but the details explained on how blew over the humans heads. And things were finally back to their version of normal.

But not without a few questions.

"How did you know the Mirror-Ratchet would react to your… 'music', Miss Nakadai?" asked Ultra Magnus as Ratchet, their one of a kind, genuine number one Ratchet, looked into his audials for any permanent damage.

Miko ignored at the gibe at her genre taste and instead leapt onto Jacks arm, smiled at them and pointed at the blushing teen.

"It was Jack's idea!"

"I thought since he was from the Mirrorverse and never met us there, he wouldn't have had an MSMD."

"Nice thinking, son," Fowler complemented.

"What exactly is an MSMD?" asked Magnus.

"It's an upgrade I developed shortly after the children came to spend time with us," explained Ratchet as he finished his exam. "I'm putting in one for you as well. It helps dampen certain sounds the children make to protect our sensory hearing and from making us go insane from it. Something I'm sure that twisted doppelganger probably never would have thought about when he came here. If he has opposite thinking to me he never would thought of the small details it takes to having to live with humans." He then smiled at Miko. "Though I think I had heard the best concert ever, so it's tolerable just for today."

Miko smiled back and giggled. "You're welcome Docbot, great to have you back."

"So what does MSMD stand for?" the Wreaker commander had to know.

All the bots and humans looked at each other with smiles before the Prime answered.

"Miko's Slash Monkey Dampener."

(*): Only Ratchet can hear him.
