Previously, On transformers Prime...

Unicron the Chaos bringer Begins to emerge from his slumber and this Causes the Autobots to work with the warlord tyrant in order to save the planet. They succeeded but it was not without the cost of one's memories. Optimus prime is now Orion pax once again, and with the Decepticons.

In the Autobot Base.

"In high site, we accomplished what was required. With Unicron's awakening, extreme measures needed to be taken: enemies became allies, allies became confidantes. And with the Matrix of Leadership, the planet Earth was saved. Though at an immeasurable, personal cost. When Optimus surrendered the matrix, he lost more than the collective wisdom of the Primes. He lost himself." Ratchet explained the previous events to everyone.

"That doesn't follow." Arcee narrowed her optics. "Optimus knew Megatron."

"They we're like BFFs!" Bulkhead explained.

"What does BFF stand for again...?" Bumblebee bweeped in confusion.

"How can Optimus remember megatron and not us?" Asked Grimlock. This whole thing is a bit confusing to him.

Ratchet choose to ignore bees question since he figured the kids would explain it later to him." If Optimus did not know his own name, perhaps it is because the title of prime hadn't been granted to him." Ratchet concluded.

"What?" Said Agent Fowler who is as confused as the kids now.

"Come again?" Said Miko.

"With the power of the matrix no longer within him, it would stand to reason that Optimus has reverted to his pre-Prime state. orion pax, a clerk."Ratchet explained.

"So He thinks he's his old self in his mind?" Asked Nurce Darby

"Hold on! You mean to tell me Optimus is some kind of Librarian and a Decepticon?!" Said Agent Fowler who is a bit mad and confused.

"Uh, What's a librarian?" Grimlock asked Arcee as he leans down to her level a bit. He never been to a library so he wouldn't know what a librarian is.

Arcee pondered a bit on what would be the best way to explain what a librarian is to Grimlock."it's Someone who's job is to sort books and records." She said.

"Oh okay, Thanks." He said as he then goes back to paying attention to what ratchet is saying.

"Being an Decepticon is a choice, agent Fowler. One that I have a hard time believing Optimus would make at any point in his life." Ratchet xplained.

"So if he's riding with the cons..." Bulkhead pondered.

"Megatron's working some kind of voodoo..." Arcee finished his sentence for him, gritting her teeth. They're going to get Optimus back, no matter what...

"Optimus may not currently be a Autobot up here." Ratchet said as he points at his head. "But I believe he will never stop being one in here." He said now pointing his chest. "We must locate him, to know for certain."

"Hold up. I have a chip lodged in my behind that lets Uncle Sam knows when I stop for donuts. Are you telling me you can't just track Optimus?" Fowler asked.

"Optimus signal has not reappeared since we embarked for Earth's core, but we must get to work finding him. Especially if we have any hope of initiating his contingency plan." Ratchet revealed.

"Contingency plan?" Arcee raised an optic ridge.

"What contingency plan?" Bulkhead as confused af rn

"The key card..." Jack held it up. "What does it do?"

"It grants access to Vector Sigma: the repository of the wisdom of the Primes." Ratchet answered.

"So it's like a super computer?" Asked Raf.

Ratchet nods to answer raf's question.

"So we can just download Optimus' memories back into him? That's great!" Jack beamed. "Where is it? Is is that one over there? Over in the back?"

"Vector Sigma is more than a super computer, Jack. It is an ancient source of mystical power. On Cybertron." Ratchet clarified.

"Jackson Darby you will NOT be traveling to another planet." June crossed her arms sternly.

"I'm in!" Miko exclaimed.

"You're not going either, Miko! Not when one of *you* can."

"Yeah, why send a boy to do a bot's job?" Asked Agent Fowler.

"Because only a Prime can access Vector Sigma, or one chosen by a Prime. Optimus gave the key card to Jack. It is now imprinted with his unique bio signature." Ratchet explained.

"So... Jack's some kind of honorary Prime?" Miko was confused

"So if jacks a prime,Does that make him leader till we get Optimus back?" Asked Grimlock.

Ratchet sighs at this." No Grimlock. But it does mean jacks the only one who can save Optimus and bring him back to us." Said Ratchet

"But why would Optimus willfully endanger a human? Especially a child!"

"Mom, I'm not a child!"

"Maybe Optimus believes there's more to Jack than meets the eye." Arcee suggested.

"All of which is moot, the key card is useless to us without a means of reaching Cybertron. Which at present we do not possess." Ratchet reminded.

"Why don't you just turbocharge the spacebridge?" Miko shrugged her shoulders.

Ratchet was about to say something about that being a ridiculous idea,but then he started to think." That is not a bad idea miko." Said Ratchet as he starts working on improving the Groundbridge immediately.

"Woah, I never thought I would hear ratchet say that." Whispers Grimlock as he grins a bit and then chuckled slightly.

Arcee giggled a bit as well. "There's a first time for everything."

Later...

While Ratchet was working on upgrading the groundbridge when he suddenly got a call from Fowler."Ratchet, are you awake!? This is an emergency!"

"Agent fowler, is it about Optimus?" He asked, hoping Optimus had been found.

"It's the cons. They're hitting the same military lab they hit two months ago." He explained, the Autobots walking up to the monitor.

"Another space bridge?" Bulkhead questioned.

"For all we know, Optimus is riding with them." Arcee said. She is determined to get him back.

"What are we waiting for then? Let's go, It's time to Rumble!" Said Grimlock with a grin as he smashes his fists together.

Ratchet opens the groundbridge." If Optimus is there, do everything you can to bring him home..." Said Ratchet.

At the Military Lab...

Breakdown and Knockout were blowing up the joint, watching the Autobots speed through the groundbridge.

"Drop the power source!" Bulkhead charged after them.

"Aren't you missing someone?" Knockout jeered with a smug grin.

The Autobots aim there weapons at the two cons, but then saw the two cons reinforcements.The Cons Air forces swooped in, raining down fire upon the Autobots.

Grimlock uses his body to provide cover for his team." Shoot them while I keep us safe!" He said as he feels a few shots hit him.

"Thanks Grim." Arcee said as she gives him a quick peck on the cheek and then starts shooting at the cons.

The Autobots were able to pick off the Vehicon seekers one by one, a ground bridge opening up for KO and his boyfri-I Mean Friend.

As They ran through, Arcee transformed and speed into the groundbridge. It then closes up.

"She made it through."Said Grimlock who stares at where the groundbridge was. He was a bit worried for her. He can't help her out if she runs into someone like megatron. He knows she can handle herself very well but he still worries.

Later...

Arcee was brought back to base with some very minor injuries. "I wasn't able to confirm Optimus' location..."

Bulkhead Yelled in anger as he smashed one of Ratchets tools.

"Bulkhead-!" Ratchet began.

"What?! You needed that?! The only thing I need is our head honcho back!" Bulkhead said slamming his fists.

"It's not your fault." Jack said to Arcee.

"If any of us needed rescuing, Optimus would've already found a way. I didn't- it's as simple as that." Arcee looked down.

There was an incoming call from Fowler.

"Ratchet, what happened out there!? Reports indicated at least a dozen wounded and the heat's on me to provide some sort of explanation!" He shouted. "If you don't pull yourselves together, the Pentagon will force me to shut down your base!" He then hung up.

"But where would you go?" Raf asked.

"Who knows? Maybe they'll ship us out to some island! Or fire us into space, wouldn't that be a welcome relief!" Ratchet said sarcastically.

"I don't blame Fowler- Optimus would've known what to do!" Arcee stomped her foot down.

"We don't actually know what he would've done because he's not here!" Bulkhead exclaimed, Arcee getting up.

"You're really good at stating the obvious- care to say anything else we already know?"

"Yeah- you can't stop hopping from one mech to another!" Bulkhead slammed his servos over his mouth, realizing what he just said.

Grimlock heard this and glares at him and then transforms and growls at him before punching him, Sending him into the wall." Take it back!" He said.

"Grah!" Bulkhead was sent back, creating a huge crater into the concrete. "Arcee, I'm sorry! I didn't mean-"

"No- no... you're right Bulkhead. I can't stop hopping from one mech to another." She scoffed with a forced smile. "Apparently it's MY fault my conjux's keep d... dying..."Arcee realized that there was a pattern, looking up at Grimlock.

Grimlock looks at her and then transforms back." It's not your fault. You couldn't control what happened to them but I promise that I'm not going anywhere." He said with a smile. He hopes that had made things less depressing.

This makes her smile a bit. She then pecks him on the cheek." Good." She said

"Wait- aren't we forgetting one positive." Jack got their attention. "The decepticons are making a space bridge that we can use to get me to Cybertron."

"But how will we find it! It could be anywhere and not to mention it would be heavily guarded." Said Ratchet who is bringing up some good points.

"Isn't it up there?" Miko pointed up.

"The term space refers to its transport range, no its physical location." Ratchet corrected her. "And we've been monitoring Earth's orbit since the last one. We'd know if it were there." He added.

"Then that means it could be here on earth!" Jack explained. "We don't really have much of a choice- it's our best shot."

"Then we better get looking..." Ratchet said as he walks over to the computer and starts searching for any types of energy spikes.

Later in the base...

Ratchet and Raf were performing a test."Long range gps activated." Raf turned on his RC car, looking over at Ratchet.

"I have doubts that our recalibrations have successfully extended ground bridge range." Ratchet feared. "But there is only one way to find out." Ratchet said as he activated the ground bridge.

Raf drove his car into the groundbridge. It exploded and the bridge powered down..."D-don't give up! I have a whole collection of RCcars!" Raf tried to cheer him up.

Ratchet sighs." No matter how many tests we do, it will not matter. It would take eons for this to work..." he said. Ratchet has almost lost all hope.

Raf left, looking down.

Ratchet sighs and then goes back to searching for any energy spikes. The groundbridge opens and then Bulkhead comes through." Any progress?" Asked Ratchet

"No sign of energon spikes. Arcee, Bee, or Grim find anything?" Bulkhead walked up to the medic.

"Not yet, They are still searching." He said. The computer starts beeping.

"What is it...?" Bulkhead approached the monitor.

"A high frequency signal, with an imbedded message, for me?" Ratchet answered with confusing.

"Optimus?" Bulkhead was hopeful.

It was Starscream.

Bulkhead: -_-

'I have obtained vital information regarding your leader. Bring medical assistance.'

Inside a forest

Starscream laid against a boulder with a lot of energon coming from his wound. Then he saw a ground bridge portal appear with ratchet and bulkhead coming through it.

"I told you to come alone!" Starscream exclaimed.

"And since when do we listen to you?" Bulkhead transformed his servo into a canon.

They just looked at his injury.

"Well? Aren't you gonna heal me?!"

"Information first, then I'll see what I can do." Ratchet was not in the mode to waste time.

"Why should I do that?" He asked With a Grin.

Ratchet stare's at him for a bit before turning to Bulkhead." Contact Grimlock."

"No wait!! I'll give you the information! Just keep that Animal away from me!" He said as he shakes in fear a bit.

Back at base...

They managed to locate the spacebridge. "Adjacent to a raw fuel supply... clever." Arcee pondered. "What's our intel?"

Bulkhead and Ratchet looked at each other. "Reliable source-"

Arcee was suspicious of them.

"Who cares how they found there info. Let's go and take it already!" Grimlock said with a grin as he smashed his fists together. He is eager to fight some cons.

"We'll directly drill down into the mines... once we secure the space bridge- we'll send for Jack." Ratchet explained. "Stealth must be an absolute priority."

Everyone gave Grimlock a glance since- yeah.

"Why are you all looking at me? I can be very stealthy." He said with a grin.

"We can only hope." Ratchet sighed.

"So, do we have a consensus?" Ratchet asked June.

"Do we know if people can even breathe your atmosphere?" June demanded.

"I'll hook Jack up." Fowler answered, so June looked at him with worry. "Completely state of the art. I still have connections on NASA."

Later...

They all went through the groundbridge. "Clear..."

They pushed ahead. Grimlock spots a few cons. He then turns to the group." I got this." He whispers.

The two cons were just standing there by themselves. One turns to the other."Hey."

"Yeah?"

"You ever wonder why we're here?"

"It's one of life's greatest mysteries, isn't it? Why ARE we here? I mean, are we the product of... some cosmic coincidence, or... does Primus really exist- watching everything? Y'know, with a plan for us, and stuff? I dunno, man. But it keeps me up at night."

The two Vehicons stared at each other.

"What? I meant, why are we in here, in this cave?"

"Oh, uh... yeah. "

"What was all of that stuff about Primus?"

"Uh... hmm? Nothing."

"You wanna talk about it?"

"No."

"You sure?"

"Yeah."

"Well I know why I'm here. To knock you two out." Grimlock said with a grin as he grabs them both and then slams them into one and other, knocking them both out. He then tosses them to the side and then turns to the others and gives them a thumbs up.

They kept pushing forward, Arcee giving a peck on Grimlock's check. "Good job, babe." They all went down the elevator.

Once they get down to the bottom level. Grimlock saw a con and then hits him on the hard. His heads goes into his body.

They finally located the bridge.

"By the Allspark..." Ratchet gasped.

"Thank you, Starscream." Arcee muttered, Bulkhead looking at her in confusion. "Who else would it be?"

"I wish I was there to throw him around. But this will have to do." Grimlock said as he lifts a drill and then throws it at two cons, killing them. He then grabs another and throws it at a group of them.

They ran in with guns blazing, the Vehicons dropping one by one.

"Operational?"

"Fully... strike team to base, objective secured."

Jack was sent in, going through the ground bridge to meet up with the Autobots.

"Locking onto Cybertron..."

The two went through the space bridge, Arcee kissing Grimlock before leaving.

Grimlock grins as he follows her and Jack through.

"Is this Cybertron?" Asked Jack as he looks around. The place looked sad and depressing.

Arcee was silent. "This isn't how I wanted you to see my home... we did everything to save Cybertron- and we failed either way."

The card began glowing, acting as a homing device.

Arcee transformed. "Let's move."They drove off.

Grimlock transforms and then runs after them. He hopes they get to vector sigma soon.

They were getting close. "Towards Kaon? The decepticon capital?"

They stopped in front of a huge building. "We'll go on foot beyond here. Step lightly, Grimlock."

Grimlock nods as he was about to step into the building , but then he hears a bunch of roars. He stops and looks around and spots a bunch on insecticons flying towards him."Get to vector sigma! I'll stay and will squish theses bugs!" Said Grimlock as he roars at the bugs.

"Be Carful Grim."Arcee said as she picks him on the cheek before picked up Jack, running off with him.

The insecticon screeched, charging at Grimlock and grabbed him with its claws, slamming him into the ground. It snapped at his faceplate.

Grimlock opens his jaws and as stream of fire comes out, melting the bugs head completely. He then pushes the body off and then gets up and stares at the other 6."lets rumble!" He said as he charges at them.

The insecticons dog piled onto the dinobot.

Grimlock uses all of his strength to throw them all off himself. He then grabs two by there heads and crushed them both. Two down, four to go.

The four looked at each other, one insecticon read to throw hands while the other three ran off with terrified screeches.

The one insecticon looked behind him, seeing how his friends abandoned him ;-;

Grimlock grins at this." Seems like it's just you and me." He then roars as he bites down on his head and then tears it off.

A few minutes later...

"Download complete!" Arcee drove out with Jack on her back, speeding to the groundbridge. "Let's get out of here, Grim!"

Grimlcok nods as he walks over to them and then stares at the groundbridge." Wait a minute. Something's not right. I'll go first and see what it is." Said Grimlock.

On the other side...

Megatron was waiting on the other side, ready to kill them. But then Optimus rolled in and then Megatron was fighting with Optimus, his back turned to Grimlock who had just entered.

"Megatron!" Grimlock said as he runs towards him and then grabs him and keeps running till he hits a wall, ramming megatron into it.

Optimus stands there for a moment till he spots Jack holding the key." I don't know if I am worthy..."

"Grah!" Megatron slammed into the stone, growling as he snapped around and kicked Grimlock off of him.

"You have no idea..." Jack began restoring the matrix.

"NO!" Megatron tried going after them.

The restoring process was completed. As Megatron brings his blade down, Optimus catches it. There was fear in Megatrons eyes.

Grimlock saw this and smiles." The boss is back." He said.

"Megatron...Begone!" Optimus clenched his fist and then upper cuts Megatron, sending him flying.

"Let's get outta here!" Said Jack. They all jumped through the groundbridge, getting back to base.

Back at the base...

The Autobots walk in and are greeted by the children and the two adults. The last one to appear is Optimus." It is good to see you all again."

"He remembers us!" Said Miko as she jumps up and down with excitement.

"Although it seems there is much I do not remember." Optimus said over to his con emblem.

"Optimus , it has truly been our darkest hour, but know this: from every indication, your spark never ceased being that off a Autobot." Ratchet remarked as everyone came closer to welcome back home their leader.
