Optimus and the Autobots were at the plants as they had just received the biology message from Cybertron.

"We can confirm that Sentinel Prime has stolen the AllSpark," said Alpha Trion.

"How could Sentinel do something so stupid," said Elita in disbelief.

"He was always egotistic, but this is just crazy," said Moonracer.

"We were surprised ourselves," said Alpha Trion. "We would send reinforcements to you, but the Decepticons have chosen this moment to attack."

"Wait, the Decepticons have launched an attack at the exact same time that the AllSpark was stolen," said Optimus.

"Yes, we found the timing rather suspicious ourselves. Though I refuse to believe that Sentinel is actually working with the Decepticons, it's more likely they saw us in a weakened state and decided to launch an attack."

"So there's no one you can spare?" Bumblebee asked.

"None of the Elite Guard, and we are still trying to deal with civil unrest because of the quakes. Additionally, the word that the AllSpark has stolen has amplified those concerns. However, your former crewmate Bulkhead and Arcee have volunteered to back you up."

"Bulkhead is coming back," said Sari excitedly.

"They should be arriving any cycle now, but I'm afraid we can't spare anyone to assist you, Optimus," said Alpha Trion regretfully.

"Alpha Trion, Prowl warned me that if Megatron got his hands on the AllSpark that he would use it to enslave everyone," said Optimus. "Is there any truth to this?"

"As you know, I am the oldest Cybertronian that's ever existed, but even I cannot fully understand the power that lies within the AllSpark. However, what I do know is that in the hands of someone as evil as Megatron, anything can be possible."

"We'll find a way to stop Sentinel and defeat Megatron," Optimus assured him.

"Then I shall pray for your success."

The screen went blank, and everyone looked at Optimus.

"So what's the plan, Boss Bot?" Bumblebee asked.

"We need to gather every ally we can because we're about to have the fight of our lives," said Optimus. "Sari, you had better warn your father so that he can spread the word to be a human of Detroit. We need to evacuate the city."

"Isn't that going a little far?" Bumblebee asked.

"So far, every single path we had with the Decepticons has demolished the city and put countless human lives in danger; I won't let it happen again. Bumblebee, you'll go with Sari to meet up with Bulkhead and Arcee, then return here."

"You got it."

Optimus turned to Ratchet. "Ratchet, you need to see if you can't get Omega operational; I get the feeling we're going to need."

"Repairs are almost complete; he should be back in fighting form the next few solar cycles," said Ratchet.

Optimus turned to Jazz. "Jazz, you better get to Wreck-Gar and bring him here."

"On it, OP," said Jazz.

Optimus looked at Ironhide. "Ironhide, check on Primal and Predacons and see if they can offer any kind of help."

"Yes, sir!" Ironhide saluted.

Optimus then turned to Elita. "Elita talk to the Dinobots and asked for their help."

"I'll do my best," said Elita.

"Moonracer, I need you to remain on monitor duty. Tell me the moment that Sentinel arrives," said Optimus.

"You can count on me," said Moonracer.

"Transform and roll out!" Optimus ordered.

They immediately transformed and headed straight towards their respective missions.

"You know I'm still surprised that Prowl talked to you," said Moonracer as she took a seat at the monitors.

"As am I," said Optimus.

"You think that he'll talk to us again?"

Optimus shrugged. "I don't know whether he does or not; we have a mission to complete."


At Kaon, Megatron was now going through his operation with Tarantulas and Shockwave. Lugnut was standing guard over the door like a statue.

"How long are you going to stand there?" Slipstream asked as she approached with her fellow clones flanking her.

"I stand here until Lord Megatron returns," said Lugnut.

"He was such a noble and devoted servant, my dear Lugnut," said Sunstorm.

"What Megatron truly needs is a bot with two servos serving him, not one," said Thundercracker.

"He's got two servos," said Ramjet.

Lugnut narrowed his optics. "Unless you have business here, I suggest you leave."

Slipstream gave a small smile. "You don't really trust us to, do you?"

"Considering zat you are clones of ze biggest Decepticon traitor in history, concern is not entirely unwarranted,' said Blitzwing as he approached them, and then his face turned to his hotheaded personality. "ESPECIALLY SINCE YOU ALSO BETRAYED YOUR CREATOR."

"Can you really blame us for betraying Starscream? He was nothing more than a snivelling coward, more so than him," said Slipstream gesturing to Skywarp, who was currently cowering behind the other clones.

"Just watch where you step; if you show any signs of betraying Lord Megatron, I will destroy you myself," Lugnut warned.

"Consider us warned," said Slipstream.

Then suddenly, the doors to the medical centre opened, and Shockwave stepped out.

"The operation was a complete success," he informed them.

"Lord Megatron is online and well," said Lugnut.

"Yes, but I do warn you that there may be side effects to this operation despite our best efforts," Shockwave warned.

"What kind of side-effects?" Slipstream asked.

"While he does not split personality issue as Blitzwing, you might's patience has severely eroded his anger height."

"With any of this, in fact, his intelligence?" Slipstream asked.

Lugnut marched up towards her furiously. "You dare suggest that the great and powerful Megatron is flawed!"

Slipstream looked at him unperturbed. "I'm merely asking if our leader is mentally sound and will not pose a danger to any of us."

"Megatron would never endanger his followers!" Lugnut roared.

Slipstream turned to his severed arm. "He cut off your own server."

"I think I can speak for myself!" said a booming voice.

Everyone turned and saw, stepping outside the medical centre, was Megatron, but he was vastly different. He now appeared to have caterpillar tracks on his arms and legs, and attached to his arms were all plasma cannons. He had a pair of short-range lasers attached to his chest, and covering his face was a mask like the kind human hockey players wore.

"Lord Megatron, may I be the first to say that it is a relief to see that your operation was a success," said Sunstorm. "And if I may be so bold, you now look even more magnificent than before, something I did not think was possible."

"Be quiet!" Megatron roared, knocking him aside harshly. He then turned towards Slipstream. "Do you truly wish to question my ability to lead? I don't need to remind you what happened to your original, do I?"

"I was merely expressing my concerns," said Slipstream.

Tarantulas then immediately placed himself between the two of them and looked up at Megatron. "Lord Megatron, there may I suggest that you calm down. You have just come out of the operation, and we still have a number of tests to go through."

Megatron looked as if he was about to question him, but then Soundwave's voice appeared over the com.

"Lord Megatron, it would appear that the Autobots are gathering allies," he said.

"To attack us?" Megatron asked.

"Possibly, but I had also intercepted a message between Optimus Prime and the High Council. Apparently, Sentinel Prime has stolen the AllSpark and is making his way to Earth. I can see only logical conclusion that he seeks to destroy you."

"So he's bringing the AllSpark to me on a silver platter," Megatron smiled. "Have the rest of operations been a success?"

"We'll be done in the next solar cycles, my lord," said Shockwave. "The Constructicons have indeed been a big help, though Dirt Boss does nude reminded who his employees are."

"Good, then very soon, we will have the AllSpark and all the Energon we want. Then it will be easy to conquer the rest of the galaxy."


Elita was now on Dinobot Island, tracking down the Dinobots until she finally found them in a clearing. All five of them, apparently Slug, had decided to rejoin his herd rather than being Scrapper's pet.

Grimlock was the first to see her and approached. "Why has spider-lady come to Dinobot Island?"

"To ask for your help," she said.

"Dinobots already helped car bots once," Grimlock reminded her.

"And we are grateful, but now we face an even greater risk," said Elita. "You remember the car bot with the big chin?"

"The car-bot that thinks that he is above Grimlock and other Dinobots?" Grimlock asked.

"That's him," said Elita. "He has stolen a powerful artefact, the same artefact that was responsible for giving you life. He now intends to use it to destroy our enemy, but we have been warned by Prowl that it could end up destroying or enslaving all of us."

"Cycle-bot said this?" Grimlock asked. "Why has he not returned to Dinobot Island?"

Elita looked at him sadly. "I'm afraid he gave up his life to save the city during our last big battle with the Decepticons."

The other Dinobots heard this and looked at her.

"Cycle-bot no more?" Snarl asked.

Elita nodded. "We're gathering allies, and we would like you to join us. The Decepticons are a danger to all of us, and then we did once try to enslave you. He tricked you into attacking us when you were first given life."

"Talking head?" Swoop asked.

"And he may look to enslave you again."

The Dinobots looked at one another and then transformed to robot mode; they then raised their weapons high.

"Dinobots will fight!" Grimlock announced.


Meanwhile, in Kaon, the Constructicons were hard at work in the city installing the equipment that the Minicons had stolen.

"Can't believe we're working for these bozos for free," Dirt Boss muttered.

"Yeah, we're getting that premium oil they make," Mix Master pointed out.

"Sorry, Mix, but I'm with Dirt Boss on this," said Scrapper. "Every time we work for the Decepticons, we always get chump change."

"Better than the Autobots; they don't pay as it all."

"That might be because we only worked for them for a few cycles before we doublecrossed them."

"So, you have problems with the way I give orders?" said a voice.

They immediately stopped work and saw Megatron approaching them with Slipstream and Lugnut on either side of him.

"N-no, I'm just merely—"

"What he's saying is that we should take orders from some nobody," said Dirt Boss.

Megatron then suddenly grabbed him so fast that no one even saw him move his arm. He then slowly lifted him up towards his face and began to squeeze.

"I'm a nobody, am I?" he said through Dirt Boss' muffled screams. "I would suggest that you stop complaining and get back to work, or this nobody will trust you in his bare servo." He then released Dirt Boss, causing him to fall to the ground panting. "Do I make myself clear?"

"Crystal," Dirt Boss gasped.

Megatron then turned and left.

"Be grateful that you received mercy from the great Megatron," said Lugnut, following Megatron.

"Is it me, or is the boss more cuckoo than normal?" said Mix Master.

Slipstream looked at him. "If you want to stay online, take my advice and keep those comments to yourself."


Ironhide was in the Orion's med bay talking to Primal; he and the Predacons had now fully recovered from their clash with Soundwave.

"So, you need help facing Sentinel," said Primal.

"Not just him, but Megatron as well," said Ironhide.

"Well, you can count on my support," said Primal and then turned to the Predacons. "Them, on the other hand, I can't say."

"ZZaspinator, doesn't zee why he should help Autobots, especially Iron-bot and Bumble-bot," Waspinator buzzed.

"Wasp, this is bigger than any kind of grudge," said Ironhide. "Bumblebee made a mistake, but that was based on bad intelligence. Intelligence from Longarm, who was the real Decepticon spy. He's the one that framed you."

"Liezz!" Waspinator yelled. "Longarm free Zzaspinator from stockade."

"To fool everyone that you were the spy so that he could commune with Megatron without a writing suspicion!"

"Predacons won't help Autobots!" Waspinator buzzed.

"Actually, I will," said Arachnid. "From where I'm standing, the Autobots are the only ones that are helping us. The Decepticons attacked us remember, and the Autobot is right; this is far bigger than some stupid grudge."

"Zpider-bot is a fool," said Waspinator and then immediately transformed into beast mode and took off.

Scorponok did the same thing and followed Waspinator.

"Well, one Predacon is more than we had hoped," said Primal.

"Just tell me what you need," said Arachnid with a smile.


At Sumdac Tower, Sari met up with Bumblebee, who was now with Bulkhead and Arcee.

"Sari, it's great to see," said Bulkhead.

"It's great seeing you two, big guy," Sari beamed.

"You finished talking with your father?" Bumblebee asked.

"Yes, he's just informed the mayor and Captain Fanzone, and they agreed the city needs to be evacuated," said Sari.

"Good, but I get the feeling that we've got a lot of rebuilding to do after this one," said Bumblebee as he looked over Detroit. "I mean, the city had barely a chance to recover from the last attack."

"I know," Sari nodded. "You can bet that the US military is mobilising."

"Hopefully, everything will be overall before they get here," said Arcee.

"My father had a tough time convincing the President not to have the US military involved, but that doesn't stop them from putting on a defensive posture. If we don't win this, they're going to attack with the full might of the US military."

"I very much doubt that human weapons will be enough to deter Megatron if he gains the power of the AllSpark."

"I know, but it makes them feel better."

"Well, with luck, they won't have to lift a finger," said Bumblebee.

"Megatron still hasn't made a move?" Bulkhead asked.

"Not since we freed the Minicons, and believe us when we say that, we find the silence unnerving," said Sari.

"But it leaves you found that you're a Minicon," Arcee pointed out.

"Yeah, it explains why my protoform was human size, but that still doesn't explain how I got here on Earth," Sari pointed out.

"Actually, when I been going over the data from that alternate universe we visited, I found something that might just answer that. According to the Isaac Sumdac from that universe, he had constantly been researching on the appearance of his Sari. He still didn't know who sent her to him, but apparently, the protoform appeared in the beam of light."

"Beam of light?" said Bumblebee. "Wreck-Gar said that a lie told him to protect the Energon."

"Could it have been the AllSpark?" Bulkhead asked.

"I don't see how; the AllSpark was light-years away from Wreck-Gar," said Arcee.

"Every time we find an answer just leads to more questions," said Sari.

"And questions are what make the investigation move forward," Arcee smiled. "We will find the truth, Sari. I promise."


Soon everyone was gathered at the plant; it was a little cramped considering the number of bots that had gathered.

"Thank you all for coming," said Optimus as he looked at everyone. "Now, as you all know, Sentinel Prime is coming here to Earth with the goal of using the AllSpark to destroy Megatron."

"Question," said Bumblebee. "Would it really be a bad thing that Megatron is destroyed?"

"Not that I'm not looking forward to seeing old bucket head kick the bucket, but using the AllSpark, the source of all life, in such a manner is a totally bad vibe," said Jazz.

"Plus, Prowl informs me that Sentinel is going to fail," Optimus added.

"Sentinel jumps before he leaps without thinking of any consequences," said Elita.

"So Autobots take down big chin-bot, but what then?" Grimlock asked.

"Then we have to take the fight to Megatron," said Optimus.

"But Kaon is completely lockdown; how do we get inside?" Bumblebee asked.

"The Minicons were able to get in and out," Sari pointed out. "Plus, the cons have found some way of transwarp themselves outside the city."

"From a sound like it's a localised Space Bridge, it would be incapable of transporting anyone through space, but it would allow them to be transported anywhere on the planet," said Bulkhead.

"So our best option is to get control of this device and transport ourselves inside," said Optimus. "Thanks for the information provided by the Minicons; we now have a map of their underground tunnels."

"But none of us can actually fit in those tunnels, sir," said Ironhide.

"I can," said Sari.

Ratchet looked at Optimus, startled. "Prime, you can't ask the kid to do something so dangerous."

"I don't like it any more than you do, Ratchet, but we don't have any other choice."

"I'll be careful, I promise," said Sari.

"Once Sari gets control of their device, we'll send a team inside Kaon and another in reserve just in case," said Optimus. "I myself will be in reserve until we can determine Megatron's location. Ratchet, I understand that Omega still hasn't recovered."

"It won't be long now, Prime," said Ratchet.

"In that case, you better hang back and stay with Omega."

"So, who's going to be on these teams?" Arachnid asked.

"We'll be split into teams of seven. The infiltration team will consist of Elita, Bumblebee, Jazz, Grimlock, Slug, Sludge and Arachnid. The rest of us will be reserved until needed."

"So what do we want to get inside?" Bumblebee asked.

"We need to make sure that the city is not operational, so we'll be targeting its power source, and then we start to engage the Decepticons."

"Do we wait for Sentinel to show up, or should we start this operation right away?" Primal asked.

"I would say that we should start now," said Elita. "If we can take Megatron down before Sentinel arrives, then we may very well avoid the worst-case scenario."

Suddenly they heard an alarm, and Moonracer quickly rushed towards the monitors.

"What's going on?" Optimus asked.

"I'm afraid we're out of time; Sentinel has just entered the system," said Moonracer.


Sentinel had indeed just entered the system, and he was now flying right past the moon towards Earth.

"I'm good to one thing Optimus can bring himself to do, and that's to destroy you, Megatron," said Sentinel.


Everyone in the base immediately began to scramble.

"How close is he?" Optimus asked.

"At his speed, he should be here in a few clicks," said Moonracer. "I'm trying to get him on the com-link, but I've it's not working, or he's just ignoring us. I'm willing to bet that it's the latter."

"Do the Decepticons know he's here?" Optimus asked.

"It will be hard to miss the power signature from the AllSpark," said Elita as she quickly began to access a console. "And try to mask it as best I can, but I think it's far too late."

"Alert Cybertron of the situation, in if they can't help, we should at least inform them of the situation," Optimus ordered.

"Should I head out now?" Sari asked.

"Yes, but do be careful," said Optimus.

"Hey, when I'm not careful?" Sari smiled and flew off before she got a reply.

Optimus turned to Ratchet. "You better head over to Omega Ratchet; we need those repairs complete fast."

Ratchet nodded, immediately transformed to vehicle mode, and drove off.

"I wonder what the cons make up this?" Jazz wondered.


In Kaon, despite Elita's best efforts, they were able to detect the AllSpark heading straight towards them.

"Lord Megatron, I have detected a powerful energy signature heading towards the planet," Soundwave reported. "It matches the energy singing too of that of the AllSpark."

"So Sentinel has finally arrived," Megatron smiled. "Then we best prepare for a welcome committee for him."


Sentinel had just entered the atmosphere and headed straight towards Detroit, immediately receiving a transmission from the Autobots.

"Sentinel, please respond," said Optimus' voice over the com.

Sentinel reluctantly opened the com channel. "What do you want, Optimus?"

"To stop you from taking such full of actions," said Optimus simply.

"I'm merely doing what you should have done when you first captured Megatron."

"But you're endangering the AllSpark, the very light source of Cybertron."

"Which is possibly the only thing capable of destroying Megatron as well as an indestructible fortress city."

"I've already seen the destructive powers of the AllSpark; it's not worth it."

"Save your voicebox, Optimus; nothing you say will convince me otherwise."

"Sentinel, if you do this, I can't protect you," Optimus warned.

"I never needed your protection!" Sentinel snapped and immediately switched off the com.

"Sentinel! Sentinel!" Optimus yelled.

"He must switch off his com," said Moonracer. "Judging from his last transmission, he should be here very soon."

Optimus looked at everyone. "You best prepare yourselves."


Once Sentinel was over the city; he immediately flew out of a shuttle with the AllSpark tied around his neck by a chain. He then immediately began to fly down towards Kaon. Then suddenly, he saw a portal opening and stepping through it was Megatron.

"Sentinel Prime, what a pleasant surprise to see you here," Megatron smiled.

"Megatron, I see you got yourself a new look," Sentinel noted.

"As have you, but I must admit I am surprised that an Autobot would steal the AllSpark. Normally your kind would risk your lives in order to defend it, but instead, you put it in danger by facing me."

"With the AllSpark, I keep ending once and for all," said Sentinel.

"Possibly, but what made you believe that you have the power to harness such power?"

"You and Starscream were able to use it, as were those meddlesome Cyber Ninjas; I don't think I'll have any problems."

Megatron laughed. "You think so highly of yourself, don't you? Starscream was only able to play around with it, and he barely scratched the surface. In truth, you have no idea what you're messing with."

"Shall we test that theory!" Sentinel yelled as he grasped the AllSpark.

Then suddenly, a powerful beam of energy shot out of the AllSpark straight towards Megatron. He kept on channelling the beam of energy for several minutes until he finally stopped, and Megatron was none.

"I can't believe Optimus had such a hard time; that was way too easy," Sentinel smirked.

"I would be so sure," said a voice.

Sentinel turned and saw a Cybertronian jet flying down towards imbibing its lasers. He barely had enough time to raise his shield, but the impact of the blast was enough to send him back. The jet then transformed into Megatron, who was now hovering above Sentinel.

"An attack that powerful is only successful if it hits," said Megatron.

Sentinel quickly fired his shoulder cannons, but Megatron quickly pulled out a pair of twin blades and sliced through his attacks. He then flew down towards Sentinel at blinding speed dealing him a powerful punch and sending him crashing down onto Trypticon.

Megatron lands on the surface, then transformed into a Cybertronian tank and immediately fired his cannons. Sentinel was still recovering from the blow he received and was unable to block them and was shot backwards.

Make continued to advance towards him and transformed to robot mode; he then approached a weakened Sentinel and ripped the AllSpark away from him.

"I should thank you for handing the AllSpark to me," Megatron smiled. "I shall keep you online long enough to see the destruction of your fellow Autobots."

Sentinel winced as he looked up at him. "Even with the AllSpark, you can't defeat the full force of the Autobot fleet, especially Omega Supreme."

"True with your Space Bridge Network, you are still far more manoeuvrable than my forces, but now I have something that easily dwarfs your Omega Supreme. Shockwave, is Trypticon finally finished?"

"It is my Lord," said Shockwave over the com.

"Then let us give a demonstration of our power," said Megatron.

Suddenly the entirety of Kaon began to move as it suddenly began to transform. In just a few moments, standing where Kaon city once stood was a giant reptilian transformer that was easily 20 times the size of Omega Supreme.

"Say hello to Trypticon," Megatron smiled.


Optimus and the others just stared in horror as they saw the giant transformer.

"We're so slagged," said Bumblebee.
