Alright here it is. The sequel to Sam's Vengeance. It as been three months since I finished the story and I'm sorry that I took that long to write the sequel.

It was very difficult for me to write the first story. I had trouble on how to start writing it. But during those months, I've come up with the plot of this story. So enough of my babbling, Here's the first chapter of the awaiting sequel. Remember, this is a Optimus/Sam story, and if you haven't read Sam's Vengeance, read it. If not, go ahead and read this story. Enjoy.

This story starts during Predacon Rising.

Chapter 1: Infiltrating the Iacon Vault

Beautiful. That is what Sam's thinking when the Sun rose from the horizon, shedding its light on Cybertron for the first time since the Great War, according to Dreadwing. Of course, it isn't truly beautiful. So many buildings, dead bodies, and ruins – it really hurts him.

But why does he cares about Cybertron and not Earth? Sam smirked. The answer was quite simple. Earth and its people are evil. They were born from Unicron, they are Unicron's children. Humans have been killing their own for many of years. Nazis and Hitler, the Holocaust, Ku Klux Klan, the Los Angeles Riots, and the World Trade Center. Hearing and reading about them really hurts Sam. Why can't humans see that everyone is the same? Why is everyone destroying their home?

But Cybertron and its people, they're different. From the stories he heard from the Autobots, everything was peaceful. Sure, they do have their own social class and oppression, but everyone works together to build Cybertron into a peaceful place. There is no discrimination towards others and everyone has a place they can call home without fear, unlike humans where people rob from each other and people sleep on the streets and try to fend for themselves while others ignore them.

Which is why Sam decided to restore Cybertron, so he can live in peace, without feeling any despair. But first he must destroy the ones who betrayed him, who made him who he is right now. Once they are gone, he'll have to find a way to make Cybertron his to rule. Also, have the people of Cybertron accept him. He wants to do this peacefully, but anyone who goes against him must be destroyed.

After he restores Cybertron, what will he do to Earth? Simple really, he'll destroy it. It's the only way he'll spare humans from their suffering. Maybe he'll spare some, like Fowler, the kids, and N.E.S.T soldiers that are still alive and kicking. Yes, he has everything all planned out.

"Master, where are we going?" Dreading finally decided to ask after a long silence.

"We are going to find that Predacon." Sam replied.

The two have been in the skies for a while now, after they left the Nemesis and the Autobots. The two have been flying around Cybertron, trying to find Predaking. Dreadwing doesn't know why Sam wants to find him He asked him that and the only reply was that he needs to keep a promise and see if he wants to remain loyal to him.

After a long search, Sam has finally located Predaking. Sam and Dreadwing landed in their robot form and began to walk around the place, filled with large debris and an empty field. What they found was surprising to them. In front of them, was a burial ground. Dreadwing informs Sam that during his time here, there has been no records of this site. Sam concludes that because of the restoration of Cybertron, the shifting of plates made them uncovered. But the main question is, where is Predaking?

"What are you two doing here?"

Sam and Dreadwing looked back and saw Predaking standing on top of a hill of scrap, looking down at them very intimidating.

"We came to find for you." Sam answered, unfazed by the look he's getting. "I still haven't forgotten about the promise I made to you. That is, if you're still loyal to me."

"No."

"No?" Sam looked at him confusingly.

Predaking jumped down from where he's standing and walked pass Sam and Dreadwing until the burial ground came into view. "I knew you would try to find me. And I wanted to tell you that I am no longer part of your cause."

"And why's that?"

"Because I want to stay here with my kind, isolated by everyone. I want them to rest in peace, not to be disturb by anybody. I hope you can understand. I thank you for wanting to bring back my kind, but it's better if they stay like that, in peace."

Sam sighed as he scratched his head. "Alright. If that is what you wish. Then I'll respect it. Let's go, Dreadwing. We have no business here anymore." The two began to walk away from Predaking.

"Thank you."

Sam gave a wave and the two transformed and left Predaking alone with the remains of his kind. Moments later, he received word from Trypticon that the Autobots have arrived on Cybertron. Sam smirked as he changed their course and headed straight towards Kaon.

Back on Earth, at the bottom of the ocean lies Megatron's dead body, already starting to rust. On the outside he appears to be dead, but his psyche appears to be alive and well. In his mind, there was a loud and familiar voice echoing in darkness, calling out his name. Inside his mind, Megatron slowly opens his optics to find the one who's calling out his name. He soon found himself face-to-face with Unicron in his giant form. Megatron feels like a small insect in the presence of Unicron's massive body. What's more is that he's in a different plane than what he expected.

"I do not understand. Why am I not one with the AllSpark? Do I yet live?" He asked Unicron.

"You do not, yet you cannot join the AllSpark because my lifeblood once flowed through your veins."

"Dark Energon."

"It binds you to my anti-spark."

"Optimus Prime used the Matrix of Leadership to imprison you within the Earth's core. Months later, you perished. So how is it that you speak to me now?"

"The foolish Prime rendered only my material form dormant. But I was once roused from slumber when someone who possess the same lifeblood in his veins like you do entered in my domain. But not only did he possess my blood, he also possess pure energy, not unlike Primus. One I have not encountered since ancient days."

"The AllSpark?" That's when Megatron's optics went wide. There is only one person who possess Dark Energon and the AllSpark. "Metatron. But how?"

"The warrior took me by surprise by using the AllSpark to its true power, and thus robbed me of my spark. He then used my own powers to rob me of what remains of my remaining powers."

Now that explains everything. Megatron knew Unicron had perished, which explained the Dark Energon meteors. Who would've thought that someone who used to be human could defeat someone who's extremely powerful.

"But now my energy form was roused from slumber when I sensed the awakening of an ancient rival across the cosmos."

"Primus. So, it would seem Optimus succeeded in restoring Cybertron... after my demise." Megatron spoke to himself.

"I now wish to finish what I began eons ago and get my revenge on that warrior. And for that, my anti-spark requires a vessel."

"So... I will live again?" Megatron asked hopefully and with unease.

"Only to serve me. Your husk will simply be an instrument of my will." Unicron stated as he optics began to glow bright purple.

In the real world, the optics of Megatron's dead body snapped open with the same purple glow. Megatron's body rose from the ocean floor with a scream and fell to his knees later. There was sounds of gears changing as Megatron's body began to reformats into a more powerful form. The sharp spikes on his shoulder grew taller and his sharpened hands grew bigger and sharper. With one final cry of pain, he shot right out of the ocean in his new jet mode and heads into the night sky.

Back on Cybertron, Team Prime are all lined up in front of the coliseum with a giant Megatron statue behind them. Optimus is in front of his team while the rest is behind Bumblebee, who is standing tall in front of Optimus as he gives out his speech.

"We have endured bitter hardship and countless battles... but at long last, our home planet has been restored. We would not be standing on Cybertronian soil were it not for the valiant efforts of both those assembled here... and our absent comrades. Ratchet, who remains on Earth to safeguard our human friends; Cliffjumper, Ironhide, and the rest of our N.E.S.T soldiers, who made the ultimate sacrifice. And Sam... who has now been corrupted by evil."

Everyone looked down in sadness when Optimus mentioned Cliffjumper, Ironhide, Lennox, Mikaela, Epps, and Sam. Sure Sam is still alive, but he has come to believe the Autobots betrayed him and is now out to destroy them. They promised that they will do everything in their powers to stop him and try to get him back to normal. They do not want to resort to killing him. Everyone looked up when Optimus continues his speech.

"But on this day, at the dawn of a new era, we gather to bestow a special honor, one earned by Bumblebee. Through his bravery and devotion to the cause of peace, long before, he rid this universe of the scourge of the Decepticon warmonger. In the company of your fellow Autobots, in the presence of our creator, Primus, the living core of our planet, and by the authority vested in me by the Matrix of Leadership, Bumblebee..." Optimus gave a tap on each of Bee's shoulder. "Arise a warrior."

Once he's finish, the other Autobots gave their congrats to Bumblebee, who is now promoted from Scout to Warrior class. Wheeljack flipped a switch in his hand, and the giant Megatron statue behind them began to explode and crumble. Once the statue was destroyed, Wheeljack and Bulkhead gave each other their usual chest-bump while Smokescreen gave a slap on Bumblebee's back.

"Welcome to the club, Bee. Warrior today, and who knows? Prime tomorrow?" He asked playfully. He still can't get over his head that he was almost the new Prime.

"Slow down, Smokey. I'm not sure I'd wish a Prime's responsibility on anyone."

"I am sorry to interrupt your celebration."

"Here it comes."

"Primes never party."

Optimus ignored the two comments as he continues. "But I must take my leave of you."

"Sir, may I ask why?" Ultra Magnus asked.

"Though Cybertron is once again able to support life, our planet is currently incapable of generating new lives. Not until I retrieve the wellspring from which all life on Cybertron is born and ultimately returns... The AllSpark."

Everyone gasped at this.

"Wait, what are you saying? Are you going to go find Sam and try to convince him to come back? Because the AllSpark is in him. You think he'll listen to us?" Smokescreen asked.

Optimus shook his head. "As the war for Cybertron reached a tipping point and the Decepticons army appeared to be unstoppable, I opted to safeguard the AllSpark from Megatron by covertly splitting its power into two and sending it to a distant sector of the galaxy. The cube landed on Earth, which was later discovered by a human and kept hidden by a secret organization called Sector 7, until it was used to destroy Megatron the first time and has transferred its power to Sam as a new vessel. The other is somewhere in space. The Matrix of Leadership will enable me to guide us to its present location.''

"Why would you split the AllSpark in two." Ultra Magnus asked, surprise that Optimus could do such a thing.

"I, myself, do not know of the reason. It was almost as if the AllSpark was whispering to me, telling me to split its power apart. One half will remain in its cubic vessel, while the other will be transferred to a different container."

"What are we waiting for? Let's take the warship and bring it back." Bumblebee said, eager to retrieve the second AllSpark, just like he did the first time with Sam and Mikaela.

"These remain dangerous times, Bumblebee. We cannot leave Cybertron unsecured, not with Starscream, Shockwave and Sam unaccounted for."

"Not to mention our stray Predacon." Ultra Magnus added, looking down at his new claw hand, remembering when Predaking crushed his original hand.

"Ultra Magnus, you will supervise patrols to find and capture the fugitive Decepticons." Optimus ordered.

"I would be honored."

"Bulkhead, you will lead the reconstruction effort. Begin by building a landing field to welcome returning refugees. Wheeljack, I will require your extensive experience navigating deep space."

"When do we leave?" He asked eagerly.

Unbeknownst to the Autobots, up above on the roof a building, was Sam, sitting on the ledge with Dreadwing behind him as the two listened to the private conversation. Sam smiled wickedly as he gained a useful information.

"Dreadwing, did my ears deceived me, or did Optimus said there was a second AllSpark somewhere in space?" Sam asked playfully while looking down at the Autobots that now split up.

"You've heard correctly, My Lord. Optimus had split the cube's power into two and sent them to different part of the galaxy. The cube landed on your home planet while the other is still out there."

Sam chuckled as he began to concentrate in order to sense the AllSpark within him. "That explains why I don't feel at full power. Optimus was clever enough to split its power. But once I get that second AllSpark, I'll become even stronger than Primus himself." And perhaps even stronger than him.

"Shall we go after the AllSpark before Optimus and Wheeljack get to it first?" Dreadwing asked.

Sam shook his head as he stood up from his sitting position. " No. I'll let Optimus do it for me. And besides, we have a job to do here on Cybertron. Take me to the Iacon Vaults. We have some research to do."

There was a huge explosion by the entrance of the Vault. All other remaining Elite Guards that is stationed there took into position, ready to defend the Vault from the Decepticons. They waited until the dust begins to clear up. But they waited too long as cannons were fired, killing all of the Elite Guard. Once the dust cleared up, Sam and Dreadwing had their cannons up, each one letting out smoke as a clear sign that they have been fired.

They put away their cannons and walked in the Vaults. Sam was amazed on how Cybertronian libraries pales in comparison to Earth's libraries. There's got to be million of even trillions of these books in the Vault. He wonders how Optimus handled his job as a archivist.

"Why are we here for, Master?" Dreadwing asked, snapping Sam out of his thoughts.

"We are here to look for a certain book. I'm sure you're familiar with the Covenant of Primus."

Dreadwing's optics narrowed. "Yes, I have. What you have planned for it?"

Sam laughed as began to look around the place, admiring it. He grabbed a book and just flipped the pages. "According to the AllSpark, it contains secrets that was written down by Primus himself. Secrets that will allow me to rule Cybertron and bring true peace." He informs as he returned the book back to where he got it from. "We're gonna have to split up to look for that book. It should be somewhere around here. After all, they did kept all the Relics here locked up."

Dreadwing nodded and went off to search for the Covenant. Sam heading to the other direction to look for the book. A few hours have past and yet they did not found the book. He contacted Dreadwing and he reported that he has not found the Covenant. Sam was becoming enrage and was sensing he was running out of time. But for what? They have all the time until more Autobots reinforcement arrive to stop the intruder that infiltrated the Iacon Vault.

The two are having terrible luck on finding it. They are almost finish searching through the Iacon Vaults and yet nothing has come up. Could it be that the Covenant of Primus is hidden inside the Hall of Records? He leaned on one of the shelves as he began to think. The Covenant of Primus, along with the Quill, are two of the most powerful artifacts in creation. And the only one who possessed them is Alpha Trion, who was holed up inside the Hall of Records when it was attacked, so it must be there now.

Before he can contact Dreadwing, he pressed a hidden switch from within the shelves, and a door opened behind Sam. Sam was unprepared for that and he let out a scream as he fell into the door that he was leaning on. His scream grabbed Dreadwing's attention as he dropped everything and ran to aid Sam.

Sam felt like he was in a very huge slide as it kept turning. He reached to the end of the slide and began to fall. But he was quick to think as transformed before he could hit the ground. He transformed back and landed safely and began to look around his new surrounding. It was so dark, he couldn't see anything. He looked up to see where he came from and saw that the hole he came from was sealed. He tried to contact Dreadwing or Trypticon to open a GroundBridge for him, but all received was static.

He snarled and made sure to be careful of traps while he tries to find a way out. He made sure to keep his hands on the wall so he'll know where he's going. He felt a switch and pressed it with out hesitation. He has his guard up if that switch was to activate a trap. But instead, it opened another door and he could see dim lights on the other side. Sighing in relief, he entered the new room.

He continued to walk down the path, his footsteps echoing in the room. This reminds him of the scary movies he used to watch with the others. And remembering what happens to people that walks down a dark and scary path, he kept his fusion cannon ready, in case something pops up. He suddenly crashed into a wall and he let out a pain yelp as he rubbed his face. Luckily, he was alone or else that would have been embarrassing. Suddenly, he heard clicks and gears beginning to shift as the wall is beginning to open up.

He entered inside the new room that opened up for him. He could sense another presence in this room and had his cannon all warmed up and ready to fire.

"Who goes there? Show yourself!" He demanded. He waited for a while now until the mysterious presence replied back.

"I have been waiting for you. The Covenant of Primus foretold me so." The voice sound old and raspy. Like almost as if this being has been alive long before Cybertron.

The whole room begin to lit up, but not too much, only dim. But he can still see very well. Once he could see well, he let out a gasp of shock has he identified the presence. He was right. This being must be someone who have lived long before Cybertron. This giant, old rusting machine sitting on his throne, staring down at him with those red optics. And by according of his height, he's say that the ceiling must be very high enough for this old robot to walk about freely. But this robot has cables attached to him, which resembles life support cables.

Once his eyes adjusted to the room, he let out another gasp as he recognized the being in front of him. He never thought he'd still be alive. "It's you..."

So, how was it? Like I said, I had trouble on how to start it. Remember, I will use information from the movies, the cartoon, video games, and more to write this story. But there will be twist.

And who is that mysterious robot? Is he a Decepticon or an Autobot? You'll all find out in a way later chapter. I'm sure it will surprise you all.

Please review on what you all think of this sequel. Next chapter: Unicron vs Sam once again.
