Prologue

A/N: so an idea popped in my head. What if the government made the Cybertronians work with the Justice League instead of keeping them secret?

Now, as usual with my stories, they are humanized. However, they still have many of the same abilities. They can connect to technology and control it; with cars they can make them transform into the robots. They have their weapons, and can still connect to the internet on their processors. They also don't have human lifespans.

Now Cybertronian ages and appearances:

Optimus—37; short, black hair; royal blue eyes, blue armor with red flames, and pale skin; Bumblebee's father; 6'6"

Ratchet—62; greying, brown hair; blue-green eyes, red and white armor, slight tan, 5'10"

Arcee—26; brown hair with pink streaks, blue eyes, blue and pink armor, slight tan, 5'7"

Bulkhead—32; black hair, green eyes, green armor, dark skin, 6'7"

Bumblebee—16; black hair with blonde streaks, icy-electric blue eyes, pale skin, yellow armor with black stripes; black markings on back (will be further described later), 6'2"

Megatron—39; black hair, red eyes, silver armor, pale, 6'7"

Soundwave—28; violet, black, and navy armor; 6'4", usually wearing visor, appearance unknown

Starscream—36, brown hair with red streak, red eyes, tan; grey, white, and red armor, 5'4" (without heels)

Arachnid—26; black, violet, and gold hair; violet and black armor, violet eyes, pale skin, spider legs emerging from back, 5'7"

Wheeljack—46; greying brown hair, green eyes, tan, white armor with red and green stripes, 5'11" (will arrive later)

Cliffjumper—29, tan, red hair, green eyes; red armor; 5'8"

Knockout—22, red hair, red eyes, tan, red and violet armor, 6'3" (will arrive later)

Breakdown—26, brown hair, tan, golden eyes, blue and grey armor, 6'7" (will arrive later)

Skyquake—34, red eyes, brown hair, slight tan, green and red armor, 6'5" (will arrive later)

There may be OCs added later on.

One Cybertronian year is equivalent to one million earth years (just FYI I don't know if that's actually true; I'm just making it up so deal with it).

This story will follow both the YJ and TFP plots, confusing I know, but just work with me, I'll be skipping some episodes I feel are unimportant. It starts off before the story actually begins. No Raf, Jack, or Miko (in the main plot anyways). I own nothing but the story. And this first post is more of an intro than the actual story, just FYI.

Batman sat on monitor duty at the Watchtower. So far nothing unusual was going on, no major criminals were out in Gotham, no world threats, and Robin, Kid Flash, and Emerald Lantern were behaving themselves—for once.

A ping came, looking over to another screen, he saw that the government was contacting them. Pressing a button, he looked at Special Agent William Fowler. "Agent William Fowler. What do you want?"

The liaison was not surprised that Batman knew who he was; it was Batman after all. "I'm sure you remember the meteor shower in Death Valley a few months ago?"

How could he forget, it was a miracle that no one was hurt, and no major explosions erupted from the impact—the league was too busy dealing with another of Lex Luthor's schemes to stop them—all they left was several huge craters in the ground.

After doing some digging—and by digging he means interrogating and hacking—he found that the meteors were actually space crafts, but it then got encrypted in an alien language Lantern practically had a heart attack and fainted when he saw. "Am I correct to assume that this is about the extra-terrestrials that landed?" he asked and got a nod in return.

"We want them to work with you. They're skills could prove invaluable, and their technology is centuries past our own," the Agent answered.

"But?"

"They have a civil war of their own. And they have confirmed that their adversaries have already arrived on Earth," he said. "I believe it's only a matter of time before they join up with you enemies."

"I see…" Batman said contemplating. "May I speak to the leader?"

Fowler stepped aside, and Optimus stepped into view. "I am Optimus Prime, leader of the Autobots. I take it you are Batman?"

Batman nodded. "Yes, and just where are you from? And just what is your goal?"

"We're techno-organic organisms from the planet Cybertron," he responded calmly. "We're here to defend your world from the Decepticons, who want to take over Earth, and strip it of its valued resources. And since some of your enemies have similar agendas with ours, it is only a matter of time before they themselves realize this if they haven't already. You know your enemies better than us, and we know the Decepticons better than you. It stands to reason that we need to work together should this situation arise."

Bruce had to admit, the man made a compelling and reasonable argument. "How can I trust you?"

"And just how can we trust you, Bruce Wayne?" Optimus replied stunning the Batman. "I have no reason to betray you. However, I'm not certain about you. And just so you know I've had the security cameras in here put on loop, the audio turned off, and Fowler left the room, so no one in this facility besides myself and my team know about you, your son, and your fellow Leaguers and their proteges."

Batman nodded, he was good. "Well, seems we have an agreement. And what of your aliases?"

"Already have them," Optimus answered. "We're moving to Jasper in two weeks, our own base is outside the city. I'll be working as a military, weapons and technological development, and foreign affairs consultant for the United States Government and the UN. Ratchet will be working in the hospital as a surgeon and ER doctor, as well as emergency League medical staff, and will be helping in the government medical development feilds. Arcee and Cliffjumper will be working as reporters. Bulkhead will actually be coming to work for you in one of your company branches in Jasper. And Bumblebee will be attending school in Jasper as a sophomore. I'm certain you can figure out just what our aliases are now."

"Looks like we have an agreement Orion Pax," Batman smirked. "Seems we'll be working very closely during your stay here."

-.-

"Ah, Lord Megatron," Lex Luthor said sitting back in his chair as he saw a muscular man sitting on a throne of a massive warship on the screen. Beside him sat Queen Bee, Vandal Savage, the Brain, Ocean Master, Ras al Ghul, and Klarion Witch Boy. "I take it you are interested in our offer?"

"While I am reluctant to work with humans," the warlord spat, his red eyes shining eerily through the darkness that hid most of his features, "you make a compelling offer. We will aid you and your Light. In exchange, you will help me destroy the Autobots."

"Consider it a deal. Welcome to the Light Lord Megatron."

-.-

"I can't believe we finally get to meet them!" Emerald Lantern exclaimed as she paced back and forth quickly. "Sure we've met other extra-terrestrials before, but they're Cybertronians! No one has had contact with them in over twenty million years! Not even the Green Lantern Corp!"

"Emerald, calm down," Green Lantern said.

"How much do you know about Cybertronians?" Batman asked from where he crouched on an outcrop looking down the canyon they were meeting in.

"Not much. They're one of the oldest species in the galaxy—maybe even the universe—and far more advanced than any other. We don't know much about their technology, but we do know that they're all technopathic techno-organics. The Primes are the most powerful it's said they can summon legendary weapons of immeasurable power and contain vast amounts of ancient knowledge. Mostly to fight Unicron, his Dark Primes, and their allies. But we don't really know the full extent of their abilities, because they never gave us all the information," Emerald explained.

"They fight unicorns?" Kid Flash questioned.

"No, Un-i-cron," she sounded it out.

"Unicron? Who's that?" Robin asked from where he sat a few feet above the Bat.

"It translates to the Devil, or Satan to be more accurate," Emerald growled. "He's known as the Chaos Bringer, if it wasn't for Primus—their name for God—he would've destroyed the whole universe."

"You've done your research." Looking up they were all surprised to see a young man in bright yellow and black armor, on the top of the cliff—a mask covered the lower half of his face, but Batman recognized him as Bumblebee. He was younger than he thought he'd be (though Prime did say they were enrolling him as a sophomore, he just thought they meant college). And his main question was why he didn't notice him sneak up on them? Especially in such a ridiculously bright color. "Nice to finally meet you all: Batman, Robin, Flash, Kid Flash, Green Lantern, Emerald Lantern, Green Arrow, Speedy, Wonder Woman, Black Canary, Martian Manhunter, and Superman."

"Where's the others?" Batman asked.

"Little ways behind me," Bumblebee said.

"Who are you?" Wonder Woman asked.

"Name's Bumblebee," he answered flipping off the ledge he was on, and landing perfectly on the ground. "Now if y'all excuse me, I've gotta let them know the coast is clear." He gave a playful salute before disappearing so fast not even Batman could tell where he went.

A few minutes later Optimus and his team came up. "Batman, pleasure to meet you in person," the Prime said.

"Likewise Optimus," the Batman said shaking his hand. "Welcome to the Justice League."

A/N: I know the prologue sucks! Next chapter will be at the beginning of both series, and Jasper is actually a major city. This part takes place two years before they start. And Erica West (aka Emerald Lantern) is Sil Vaturha 98's OC; she is Green Lantern's protégé, she has red hair, green eyes, is 14 years-old, and is Wally's cousin.
