Silence. That was all that was heard for a time that felt like hours. Jack was staring in awe at the sheer size of the mech. It looked like it was at least 80 meters tall, and had huge arms. It had a dark blue paint job on the shoulders and gun-like appendages on the arms. The chest area was huge, and it had what looked like large vents in it. There were massive armor plates on the legs, which had a blue-ish steely look. Also, the guns on the arms were REALLY big, they looked like they could do serious damage even to Megatron.

"Umm, can I ask who you are?" Jack asked out of the blue.

The teenager hesitated, and told Jack his name is Chase. Chase was a little chubby, with a suit of armor on that had a blue paintjob, with yellow trim and a weird symbol on his left shoulder-guard. His suit was a little boxy, with large shoulder guards and what looked to be some pretty thick chest plates. He also had blonde-ish hair and he had glasses. Jack told his name as well, and introduced Arcee, which was still looking at the robots' head with wide eyes, wondering how the humans could build something that big.

"Umm, is it alright?" Chase asked, with a little concern, not knowing that Arcee was a girl.

"Yeah, she's fine. Just a little surprised." Chase was surprised.

"Wait, she? Since when do robots have genders?" Chase said, confused.

"You don't want to know, anyway, she will be alright."

"You kidding me, she looks like she just saw a planet explode up close and personal." Chase said sarcastically.

"Hey, Arcee. Snap out of it." Jack shouted, apparently making Arcee jump a little bit.

"Oh, sorry. Just… wow. Why does it need to be so big?" Said Arcee, a little quietly.

"Oh, this thing? It controls the ACU." Jack and Arcee were both really confused at this point, and showed it. Chase then explained it pretty good detail on what the ACU does and why it needs to be so big.

"Wow, kinda expected that it was used for war, but why is only one person piloting it?" Chase said, a little coldly.

"I am a commander. Basically, I use this to relay commands to my army, which is actually completely autonomous." Jack was the one that was wide-eyed now, he thought that only Cybertronians were the only robots who could coordinate, but now. After a few moments, he snapped out of it.

"Are there more of you?"

"Yes. In fact, 2 more are headed towards this planet. By the way, what is this planet called?" Jack burst out laughing, and Arcee was wide-eyed in disbelief. If he is human, how does he not know what Earth is?

"What's so funny?" Chase said, concerned. Arcee snapped out of her daze.

"This is Earth. Why, where are you from?" Chase was almost just as wide eyed as Arcee when he heard this.

"Wait, this is Earth?"

Chase was probably the one that was most surprised by now.

"I just left Earth 5 hours ago. How can there be 2 Earths?"

Chase was thinking a lot by now, and Jack was still laughing until he heard what Chase said. Jack got up from the ground, and proceeded to ask what Chases version of Earth looked like.

"It is almost all city, there are a few lakes and grasslands, but that's because of the natural preservation act. Also, I have never seen or heard of sentient robots living on Earth." Chase said, still confused.

Then, Arcee thought of something.

"Wait, what day is today. By your standards." Arcee asked Chase.

"Umm, it's Sunday, June 14th, 2986 A.D. Why, what time is it for you?" Jack froze.

"This is May 10th, 2014. You sure that you got that right?" Chase was wide eyed.

"Wait, if we have different dates, and I just left 5 hours ago, then did I just go back in time?" Jack and Arcee thought about those huge energy surges.

"Wait, did you detect two large energy signatures when you took off?" Arcee asked. Chase put on a confused look.

"Yes. In fact, it took out my ships systems for a few minutes. Why, did you detect them too?" "Yes. In fact, it shut down our power for a few minutes too."

At Autobot Base

"What's taking Arcee and Jack? They should have called back by now." Ratchet asked Optimus, worried. "I don't know. I'll contact them." Optimus said as he lifted his hand to his head.

At the coordinates

"So, what does this mean?" asked Arcee. "I don't know. It might have been a coincidence." Jack said. Then, Arcee started receiving something on her radio.

"Arcee, do you copy? What is your status?"

Arcee jumped at this, but recognized the voice.

"We just met another human, apparently with a giant mech. No, seriously, you need to come see this." Arcee told Optimus.

"Alright, I'll be there. Is our friend hostile?"

"Negative, he was just as surprised as us when we met each other. By the way, he is human." Arcee replied.

"Wait, who is she calling?" Chase asked.

"Her leader, Optimus. He's a Prime, a leader." Suddenly, a large, green vortex of energy opened behind Arcee, and Optimus came out. His huge, red and blue figure stepping out into the sunlight.

"Greetings, human."

"I take it that you are Optimus? Also, my name is Chase." Chase remarked.

"My apologies, Chase. So, where did you come from?"

Chase told Optimus how he is a commander of the UEF, a coalition of planets that are controlled primarily by Earth government, and how he left Earth 5 hours ago only to land on another Earth. "Interesting. We might need to do some more study on what happened. Anyway, I am the leader of the autobots, from the planet cybertron."

Then Optimus told Chase how cybertron was in a civil war for thousands of years, and they are the only known autobots left after they evacuated.

"Wow, seems like the war killed off a lot of you."

"Indeed. Billions of lives were lost, and Megatron isn't letting up. He plans on taking over the galaxy, and putting it under his tyrannical fist." Just as he said that, a low humming sound could be heard. Optimus looked up, and he saw a huge, purple and black ship with a pointed spike on the front.

"The Nemesis. The Decepticons are here." Optimus shouted as a huge starship came to view. Optimus looked at Chase, "Chase, can you use that ACU for combat?"

"Sure can, just give me enough time to get in." Chase shouted, eager for combat. Also, just as he said that, another spacecraft came in. This time, it was dark blue with yellow trim, and looked more like a transport craft. It was a bit smaller, too. It flew in low, about 3 miles away, and something teleported in. "That is one of my friends, Jade. She is another commander, in a more up-to-date ACU." Said Chase as he got into the head of his ACU. Just as that was happening, though, the Nemesis stopped.

On the Nemesis

"So, the autobots got a new toy to play with? How amusing." Said Megatron as he looked at the clearly-huge robot that was docked to a large tower.

"Let's see what it can do. Decepticons! I will be back, I need to see what is happening down there."

"I will keep the troops ready, in case you need assistance." Starscream said as Megatron walked off the bridge.

On the Ground

Just as the head of the ACU got on, Megatron came out of the Nemesis, and landed only 50 meters away from everyone else. His sleek, alien design and huge arm cannon was intimidating for Chase, but since he was getting into a robot at least three to four times as tall as Megatron, he wasn't that worried.

"Optimus, long time, no see," Megatron smirked.

"Megatron." Optimus said coldly. Everyone tensed up, and Arcee silently called for bulkhead and Bumblebee to ground bridge over.

"So, I see you have a new toy, hmmm." Megatron grinned, thinking it would be easy to crush the robot. "Megatron, you have no business here. Leave us be, and we won't destroy you." Optimus glared at Megatron, making sure he knew what was in for him.

Megatron laughed, "Oh Optimus, you never disappoint. Unlike you, Starscream." Megatron yelled into his radio, making Starscream actually gulp.

"You really think that you stand a chance against me? We have been battling for thousands of years!" Megatron laughed maniacally. It's probably a good idea to get into the new suit. Jack thought as he went to a conveniently placed barn house. Megatron, seeing Jack running away, said, "I see you brought two humans with you. That one is being smart. For now." Megatron said, the last part to himself.

Chase was excited: this was his first time in the field. "Time to test this puppy out!" Chase shouted as he hit the ignite button in his cockpit. Time to kick some robot ass. He thought to himself.

A loud hum could be heard as the robot burst into life, its' reactor giving a high pitched whine as it powered up. "Hmm, so your toy actually works? Impressive." Megatron told himself. "Too bad it won't be for long." Megatron said to himself, again. "Decepticons! ATTACK!"

Shit, I should hurry. They need me out there. Jack thought as the suit assembled around him. Once it was done, he literally kicked the door 10 meters, assault rifle blazing at the incoming decepticons.
