Summary: While out searching for Energon, Optimus and Jack are ambushed by the Decepticons. They escape but Prime is severely injured and with no way to contact the base for help, they were on their own. That is until a human with a Black Trans-Am came along and offered to help. Will the stranger discover the Autobots secret? Can Jack trust these new people?

Note: This is my first attempt at writing Transformers: Prime crossover fanfiction. Please, no judging, leave a review on what you think?

In the Jasper desert, a bright red and blue semi was seen traveling down the road, it was Optimus Prime, leader of the Autobots from the planet Cybertron and sitting in the driver seat was a young human named Jack Darby. They had detected an Energon Signal and with the others out on patrol, it was Optimus who decided to check it out.

He had offered Jack to come along with him since the other children were with their guardians on Patrol. So right now they were on their way to the location where they detected the Energon signal. "Optimus, if you don't mind me asking why did you ask me to come along with you?" He asked curiously.

"I believe that it would be a good learning experience for you. As well as a good start for your training on sensing for Energon." he explained as Jack nodded as he thought back to when this all started:

One Month Ago

Jack was standing in front of Vector Sigma where the key was supposed to go into, but when he placed the key in the slot, he felt a surge go through him, a tingling sensation. He let out a yell as his world went white around him before everything went dark.

When he woke up, he looked to see that the Matrix was downloading as he heard something and looked to see scrapplets coming heading towards the key, but Jack stood up and held them off long enough for the download to complete.

By the time he was done, the download was complete as he took the key and ran out of the chamber, not noticing it glowing slightly when he touched it.

A few days after his trip from Cybertron, he was at home by himself when he started showing….doing things no human could, at first he thought nothing of it thinking it was all in his head. But the next day, he fell off his bike and injured his arm. When he looked he was horrified and stunned at what he saw because not only was he bleeding, but he could see something else, instead of flesh he was met with metal like flesh with a hint of blue and right then and now, he knew that he needed to tell Optimus.

After he told Optimus and showed him his arm, he took the boy to Ratchet who was also stunned and did a scan. "Impossible…somehow his DNA along with his skelector structure have all been altered to those of a…..Cybertronian." he revealed stunning the group of Autobots and the two humans.

Present Day

Ever since that day, Optimus had taken it upon himself to train Jack on using his new found abilities, seeing as he felt he was responsible for the boy's altered…self after discovering that Vector Sigma had something to do with Jack's change. On the outside, there was nothing but human flesh to the human eye, but on the inside he had the flesh of a Cybertronian, you could never tell unless he got injured and started bleeding. He decided to keep this to himself and the Autobots but never tell his mother as she would freak out.

So right now, it has been a month since his discovery, as time went on, he found that he can do things that no humans could. For Example, he senses Energon, especially within the Cybertronians as well as being immune to its toxic effects on humans. He can also read and speak Cybertronian with no problem as he could understand whatever Bee was saying.

He can control any and all tech with his mind, including talking to Optimus via telepathy. Optimus had also agreed to help protect the boy whenever Arcee can't because if M.E.C.H was to find out, especially the Decepticons about, then they would stop at nothing to get the boy and use it for their own personal gain.

The boy was brought out of his thoughts when they stopped and Jack saw that they were at the location of the energon signal, Jackson got out as Prime transformed and looked down at the boy, "Alright Jackson, I'm gonna need you to concentrate. Remember what you learned. Can you sense any Energon around?" he asked as Jack took a deep breath as he crouched down and placed his hand on the ground as he closed his eyes and concentrated.

Anytime when he detects Energon, it gives off a pumping sound, like a heartbeat, but in this case, he didn't hear or feel anything. After a few minutes he opened his eyes and shook his head.

"No. I can't sense any of it here." he replied, standing up as he looked around to see nothing but sand stretching for miles. Suddenly he got a bad feeling. Something isn't right, "Optimus, something doesn't feel right here." he said as the Prime nodded, "I agree Jackson, perhaps it's best if we….." Suddenly there was an explosion making them yell out in surprise as the two felt a surge of energy as they were sent flying back.

Jack landed with a grunt as he sat up and looked to see Megatron and a few Vehicoons, "Ah, well if it isn't one of the Autobots pets." he declared as he unsheathed his sword as he raised it, the blade pointing towards the boy and brought it down, Jack closed his eyes and covered himself with his arms waiting for the worst when "NO!" someone yelled.

He opened his eyes to see Prime getting between him and Megatron just as the sword made contact with the Prime stabbing him in his side making the Prime yell out in pain, "JACKSON. RUN!" Prime yelled as he kicked Megatron away with a grunt before seething his own blade.

The boy got up and ran away from the fight. He spotted a boulder as he hid behind it, panting from all the running he took out his phone to try and call the base, "Scrap!" he whispered. There was no signal. He knew that something didn't feel right when he didn't sense any Energon. This was a trap. But for who? Him? Or Optimus? He didn't know.

Jack peeked from behind the boulder to see Optimus fighting the Vehicons as Megatron looked around, probably looking for him. He got down to keep from being spotted Optimus? Are you okay? He asked through their link.

Don't Worry about me. Are you alright? Prime asked as Jack sighed, he could hear Prime grunting against the Vehicons. For now! I'm hiding behind a big boulder and Megatron is looking for me. He replied as he peeked from behind the boulder again only to freeze in his tracks as he looked up.

His eyes widened, because right above him was Megatron, with that smirk on his faceplate Scrap! He found me He said as he got up and ran as fast as he could. A second later blasters hit the ground, no doubt trying to hit him as he let out a startled yell as Megatron chased him.

HANG ON JACK! Prime yelled through the link, he can feel the Autobot leaders' fear. Just then an energy blast hit, almost hitting him causing him to be sent flying and landed to the ground with a grunt. He groaned as he turned on his back to see Megatron. "You're coming with us boy!" He bellowed.

Just then Megatron was sent flying, Jack looked to see Optimus holding his side with one arm while a cannon in the other. "Jackson, get ready.'' he said out loud. Jack didn't know what was gonna happen but he nodded as he stood up with a wince. He looked to see Megatron getting up as Optimus shot his blaster in the sand around the Decepticon leader to create a smokescreen for them to escape.

Optimus transformed into his alt mode grunting in pain, Jack felt it as he got in and Prime put the pedal to the medal and drove away as fast as he could to get away from Megatron. Both can hear the angry yell from Megatron when they escape. "Jackson, are you alright? Were you harmed?" Prime asked as Jack shook his head. He looked down to see he skinned his elbow and looked to see some of the silver flesh showing.

"Just scraped my elbow a little. I'm okay. But what about you? Are you okay?" he asked, concerned for the Autobot leader as he rolled his sleeve down to cover up the scrape. It was a few minutes before he answered "We must get you as far away from Megatron as possible, meaning we have to put distance between us." he said avoiding the question, Jack nodded, he knew that the Prime was lying and he could call him out on it, but one thing he was right about, they need to put as much distance as they can from Megatron.

XxXx–

It has been a few hours since the fight with Megatron, the teen was asleep when suddenly he heard Prime grunt in pain and a grinding noise was heard. Jack felt it, causing him to flinch as he sat up in the seat, "Optimus, what's wrong?" he asked, voice laced with worry. "It's nothing. I am alright Jackson." he said in a strained tone, Jack sighed and knew that Optimus was hurt, because he could feel it, something was wrong with Optimus. "Optimus, I know something is wrong with you. I can feel it and you know it. What's wrong?" he asked. It was silent for a few minutes.

Just then, Optimus swerved a little before he straightened out, "I don't know. My diagnostic system seems to be damaged during our encounter with Megatron." he responded as he slowly pulled over and came to a stop. Just then, Jack touched the dash and felt his heart drop, something was wrong, Prime was losing Energon.

He stuck his head out the window and eyes widened as he looked behind them, "Scrap! Optimus, you're leaking Energon." he said, looking at the trail of leaking Energon.

"Must've been when Megatron stabbed me." Prime said as Jack got out as he ran around to the passenger side, he got down on the ground as he scooted underneath Optimus' undercarriage with a grunt and spotted the leak.

It was like a big cut along one of the fuel lines Scrap! He thought.

What is it Jackson? What do you see? Prime asked.

I found the leak but It's bad Optimus. What about your Automatic repair systems? Jack replied through the link as he tried to think of a way to fix the leak. He looked to see his gray shirt over his white long sleeve shirt, he shrugged it would have to do. He thought to himself as he took off his shirt.

It's offline as are my guidance systems. Megatron must've done more damage than we had previously thought Prime said as Jackson nodded.

I'm going to stop the leak, it might not be much but at least it will keep Megatron off our trail. He replied as he used his shirt and wrapped it tight around the fuel line and tightened it making the prime grunt. That should do it. Are you okay? He asked the Prime, Yes, Thank You Jackson. he replied as Jack nodded and slid out from under the truck as he started to walk to the other side.

Note: I do not know much about Cybertronian/Transformer Anatomy and systems, so I'm winging it.

"Jackson." Optimus called out, making the boy stop and look at the truck, "Allow me to Apologize, If I had known that it was an ambush, I would not have let you join me." he said. Jack can feel the guilt coming from the Prime as he patted the hood of the truck, "It's alright Optimus! Nobody could've known that it was a trap, not even the Great Optimus Prime." he said with a small smile.

"It's okay look, you're okay and I'm okay. That's what matters, I don't blame you for getting us into this mess." he said to the Prime, hoping it will help him feel better. It seems to have worked because now the Prime felt less guilty, but was replaced with warmth.

"I…Thank You Jackson." he said sincerely as the boy nodded. "Of course. That's what family is for." Jack replied as he opened the door and got into the cab. "Now, let's check your Energon levels." he said as the dash lit up and he looked to see it was dangerously low. "Uh, Optimus? What happens when your Energon is at a dangerous level?" he asked.

It was a few minutes before the Prime answered, "Then I would go into Emergency Stasis to conserve my Energon supply." he answered as Jack nodded. "That might be a good idea because your levels are dangerously low and we don't have any spare Energon." he told the Prime.

Jack nodded, " Well, let's see if we can get you fixed up." he said as he moved his arm under the seat as he took out the on board self repair kit that was kept underneath the seat.

But before he could get started, Jack felt an alarming feeling coming from the Prime. "Jackson, we have company." Optimus said as the boy looked in the side mirror to see a black car approaching

"Decepticons?" Jack asked in alarm, "No. But, I feel something coming from the car, I do not know what it is." Optimus replied as Jack nodded. "What do you wanna do?" the boy asked, hoping the autobot leader had a plan.

It was a few minutes before he got an answer, no doubt thinking of a plan, "Jackson, I'm gonna have to go into Emergency Stasis. But if we are to survive and stay ahead of Megatron, we're gonna need some outside help. These strangers may be our only chance." he said as Jack looked at the dash stunned. "I thought you didn't want any more encounters with humans?" he said.

"That's correct. But I fear we have no choice in the matter, but keep in mind we must maintain our cover." Prime replied as Jack nodded and sighed. "Got it. Rest now Optimus, I'll get us home. '' he said as he felt the connection had been severed meaning the Prime had slipped into Emergency stasis. He sighed and got out of the truck and started waving the car down.

A Black Trans-Am cruised down the road in the Nevada Desert, with a human by the name of Michael Knight in the driver seat. They were on their way back to the Foundation after stopping a black market arms deal that involved a military general. Michael had the window down, his sunglasses on and was enjoying the peace and quiet. That is until it was interrupted by the beeping from Kitt's monitors.

"What is it Kitt?" Michael Knight asked as he sat up straight. "I don't know Michael but I am detecting a trail of an unknown element that I am not familiar with." he said stunning the driver because Kitt had every single element known to man in his CPU. "That's impossible," Michael said.

"I am also detecting a stalled truck up the road and it seems to be the origin of the unknown element." he said as Michael hummed, "Must be a leaking fuel line. But what I don't get is, what kind of fuel is this truck using to make it unknown?" he asked, confused.

"I don't know Michael. But there seems to be someone with the truck, a teenager so to speak waving us down." he said, confusing the driver even more. Just then the said truck appeared in the distance. "Is that the truck?" Michael asked.

"Yes Michael." Kitt replied. "Let's see if we can offer some help." Michael as he slowed down and pulled over, guiding Kitt in front of the truck. "Scan the truck for me will ya pal?" he requested as he got out.

When Jack saw that the car was slowing down, the kid took a deep breath to calm his racing heart, he was nervous, he didn't want to mess this up. He looked towards Optimus as the stranger pulled over in front of the truck. He only had one job: Maintain cover. Don't give away anything. He nodded to himself as he saw the stranger get out of the car and approach him. "Hiya, name is Michael Knight, need any help?" the guy asked as Jack nodded.

"Hey I'm Jack Darby but Yeah, my dad's truck broke down so he went to try and get some help and left me to watch the truck." he said, "But that was a few hours ago." he said silently praising himself for the smooth lie. The stranger nodded as he walked to the truck to get a closer ;s heart started racing as Michael walked around the truck getting a good look at it. They hope that the stranger doesn't see anything out of the ordinary.

Michael stepped away from the truck as he looked at Jack, "Mind if I take a peek under the hood see what the problem is?" he asked, but just as Jack was about to answer, the watch on Michael's wrist started to beep. "I'll be right back." Michael said as he left towards his car.

Jack let out a small sigh of relief as he looked towards Optimus. "That was close." he whispered, knowing that he couldn't hear what the boy was saying, but it helped with the nerves. But just then, Jack couldn't help but look towards the black car because he felt something, like a presence within the car, just like when he could feel Optimus or the other Autobots but this one was different.

It's technologically advanced that he can tell, but doesn't beat those of a Cybertronian. Something was odd about that car, he didn't know what but he would have to be cautious around it and Michael. He would have to talk to Optimus whenever they get wherever they're going.

XxXx–

Michael opened the door and dropped into the driver seat, "What's up buddy?" he asked, hoping the car got something. "I don't know Michael but I picked up something….I noticed something strange coming from the truck when I scanned it." he said as Michael looked at the voice modulator with a confused expression. "What Is it?" he asked,

Just then the sound was heard through the cabin:

*Thump. Thump. *

"Is that….is that a heartbeat?" Michael asked, stunned, because it was impossible. "It is Michael, I also noticed the boy's heart rate accelerate when you got close to the truck. "Either he's nervous about being around strangers or he's hiding something and it could have something to do with that sound." he said as he sighed.

"I believe you're right Michael. But what I don't know is: How can it have a heartbeat?" Kitt asked as Michael shrugged.

"I don't know. But if it is alive, who or what is it?" He asked his own question as he looked through the side mirror and saw the boy leaning against the door of the truck. "And the only person who would know is the kid," he said as Michael sighed.

"Notify Devon and tell him what we discovered and we'll take the kid and the truck back with us to the Foundation. Either way, he shouldn't be out here on his own." he said as he opened the door to get out. "Wait, there's more." Kitt said as Michael looked at the dash. "I also found something strange about the boy." he informed as Michael nodded. "Go on." Michael replied.

"When I scanned him, the results were…I don't know, puzzling, I detected an injury on his left elbow, but the reading I got from it was messing with my scanners. He's also giving off some type of signal of unknown origin." he said as Michael sighed and took in the information he was given.

After a few minutes he nodded as he got out and approached the boy.

XxXx–

Jack sensed Michael approaching him as he opened his eyes and looked to see the stranger, "Well, today is your lucky day because we'll tow you back to our headquarters in Las Vegas." he said as Jackson felt his heart drop. "Headquarters? Of what?" he asked, suspicious of the stranger now.

Michael sighed. "Look, I'm not supposed to tell anyone but I'm with the Foundation For Law and Government, long story short, we help apprehend criminals who operate above the law. We go after people that the police can't." he said as Jack nodded and bit his lip in thought.

It's like Optimus said, they could be their only chance and they do need to get away from Megatron as far as possible and with the trail of Energon Prime left behind, sooner or later Megatron will get to them and Optimus is too injured to fight. So with no choice he sighed and nodded. "Alright! But let's make it quick. I don't wanna wait here anymore." he said as Michael nodded.

"You got it!" he said as he grabbed a tow hook from the back of his car and got underneath the front of the truck and attached the line before standing up with a grunt. "Alright, let's go. Get in." he said as Jack got in the passenger seat. "Whoa!" he said as he looked at the dash. "I know right?" Michael said as he started up the car and carefully drove out to the road towing the truck behind as they drove away.

So that's what he was sensing, he could now feel that there was a presence in here, just then fear settled in his stomach, if this car was alive somehow, where did it come from? Is it an Autobot or a Decepticon? Optimus ruled out those two so he must be something else. Human based technology like MECH.

He felt his heart racing at the thought but took a deep breath and leaned his head back and watched the scenery pass, hoping the stranger didn't pick up anything about the boy or how he was acting. He looked through the mirror at Optimus and so far, the leak was holding, but Optimus needed Energon or he'll die. Primus, please help Optimus. What should I do? He thought as he fell asleep.

Note: Well, that's it for the first chapter. I know it's long but I hope you enjoyed reading it. I might add a second Chapter depending on what this gets. Until Next Time.
