Three Worlds, Two Wars

Summary: It takes only moments to change everything as one knows it. It takes only moments to pull the world out from under one's feet. How does one handle the change that happens? Does on give up? Or does one roll with the changes and make the best of them? HP/TF07 x-over

Disclaimer: I do not own Harry Potter nor do I own Transformers. If I did Prowl would be in Revenge of the Fallen and Sideswipe would have his twin and be a Lamborghini.

Note from the author: I'm gonna go ahead and say this now in hope of avoiding reviews asking about it in caps, italics, bold, and underline, the whole nine yards. 'THREE WORLDS, TWO WARS' IS NOT 'REVENGE OF THE FALLEN' COMPLIANT. I REPEAT, THIS STORY IS NOT 'REVENGE OF THE FALLEN' COMPLIANT. There may be lines or characters I incorporate later. I've yet to decide if I going to include Skids and Mudflap. They were hilarious. Now…on to the story.

Before time began, there was the Cube. We know not where it comes from, only that it holds the power to create worlds and fill them with life. That is how our race was born. For a time, we lived in harmony. But like all great power, some wanted it for good, others for evil. And so began the war. A war that ravaged our planet until it was consumed by death, and the Cube was lost to the far reaches of space. We scattered across the galaxy, hoping to find it and rebuild our home. Searching every star, every world. And just when all hope seemed lost, message of a new discovery drew us to an unknown planet called... Earth. ~ Optimus Prime

Chapter Two

"What have you been doing since you've been gone?" Hermione asked from where she stood in the middle of Harry's private room.

Harry glanced at her from where he was bent over his trunk, unpacking. He was happy to have escaped from Hogwart's version of the Spanish Inquisition. The only thing missing from the Gryffindor's interrogation had been the torture and the pendulum. "This and that," Harry replied as he pulled a stack of picture frames out of his trunk.

"This and that? Details, please," Hermione laughed. "How did you manage to get a sports car all the way up to the tower?" Sure enough, there was an emerald green and silver Ferrari F430 in the corner of the room.

"I have my ways," Harry smirked. He crossed the room and started placing his photos on his bedside table. His gaze lingered on the frame in the forefront for a moment before he turned back to his trunk to continue unpacking.

Hermione glanced at the photos. There appeared to be two or three different people in each one with shiny cars in the background. She picked up the one Harry had been staring at. The frame was silver with black engravings that one the top read 'Til All Are One' in a flowing cursive and on the bottom read 'Jazz, Lightningstrike, and Prowl'. In the picture two men stood one either side of Harry each with an arm thrown over his shoulders, smiling happily at the camera. Though, Harry and the one on his left had rather mischievous smiles. Behind them were Harry's green and silver Ferrari, a silver sports car and a black and white muscle car.

"Which one's Jazz and which one's Prowl, Harry?" Hermione queried. "And what kind of cars are these?"

"Jazz is on the left and Prowl's on the right. Jazz is…drives a '07 Pontiac Solstice Coupe and Prowl drives a '05 Ford Shelby Cobra GT500." Harry smiled sheepishly. "We're all kind of car freaks, my friends and I."

"I couldn't tell," Hermione said sarcastically. "What are everyone else's names? Or rather, nicknames, Lightningstrike."

"I go by Striker, by the way," Harry said as he crossed the large room (large was an understatement. The ceiling had to be at least 20 feet tall and the room at least 15 feet long and wide). "Lightningstrike's a mouth full."

He picked up a plain black frame. "Ratchet, Sunstreaker, and Sideswipe. 'Sides and Sunny are twins. I don't know how Ratch deals with them sometimes; they can be quite a handful. They give Prowl fits. He's constantly throwing them in the brig for something or another." He tapped the two sleek sport cars. One was red with black accents and other was sunshine yellow. Between them was an obnoxious yellow-green emergency vehicle. "Two '07 Lamborghini Murcielagos and a Hummer."

Harry set that frame down and picked up another one. "Optimus, Ironhide, Major Will Lennox, Will's wife Sarah, their daughter Annabelle, and Tech Sergeant Robert Epps. Will and Robert were the ones who got me in the military. Optimus has the big truck with the red flames. It's a Peterbuilt. And trigger happy Ironhide has the '06 GMC Topkick. Will and his family bum rides off of Ironhide and Robert's not around much."

The next photo, "Wheeljack and Bluestreak. 'Jack drives an '04 Jeep Grand Cherokee and Blue has a Mitsubishi Eclipse." He pointed at a red, blue and green SUV and silver two door. "Jack's an scientist/engineer, constantly blowing things-and his lab-up. I still haven't figured if he likes explosions or if he just has a lot of accidents. Blue can talk your ears off."

The last frame. In it was a flashy yellow muscle car with black racing stripes, two teenaged boys and a girl. "Bumblebee, Sam Witwicky, and Mikaela Banes. The 2010 SS Camaro's 'Bee's. Sam and him are best friends and Mikaela's Sam's girlfriend.

"Why don't some of them have nicknames?"

"They aren't around constantly. Sam has his family, college, Mikaela has hers. Will and his family have their own place, Robert's constantly on assignments. Just a bunch a chaos, really. But I wouldn't trade if for anything."
"You're not staying, are you? After this year, you're leaving."

"Yes. They're all my family. Over there, with them, I found people who like me, not the Boy-Who-Lived…"

"But…"

"I know Hermione. You, Sirius, Remus. But not only did I find acceptance and family, I found love."

"Who? Jazz, or Prowl?"

Harry just looked at her.

"Both?!"

"There are things you won't understand right now. Maybe, maybe, in a couple of months, I'll explain everything."

"I don't like it, but I'll accept that you'll tell me later. I have one question though."

"Shoot."

"Do they make you happy?"

"More than you can imagine."

--------------------------------------------------------------------------------------------------------------------------------------------------

"Why are you here?" And that was the million dollar question.

"We are here looking for the All Spark. And we must find it before Megatron."

"Mega-what?" Sam asked.

"Some big arse evil bloke from the sound of it," I said.

"Ya hav' no idea," Jazz replied.

Optimus touched the side of his head and the alleyway was transformed into a dying planet with towering structures. Jazz keened from beside me, Ratchet closed his eyes and Ironhide crossed his arms and glowered.

"Our planet was once a powerful empire, peaceful and just…" Optimus explained.

"Know the feeling," I murmured.

"…until we were betrayed by Megatron, leader of the Decepticons. All who defied him were destroyed…"

I wanted to stomp my foot (yes, I realize how childish that would be), scream, cry and laugh all at the same time. How in Merlin's name did I manage to get caught up in the middle of an intergalactic war just after escaping from another war? I cursed my luck.

"…Our war finally consumed the planet, and the All Spark was lost to the stars. Megatron followed it to Earth, where Captain Witwicky found him."

"My grandfather," Sam murmured weakly.

I was still fuming (pouting would have been a better description).

"It was an accident that intertwined our fates."

"Fate's a bitch," I said angrily.

"Megatron crashed landed before he could retrieve the cube. Captain Witwicky accidentally activated Megatron's navigation systems. The coordinates to the cube's location were imprinted on his glasses."

Same looked puzzled. "How do you know about his glasses?"

"Ebay," Optimus said.

"Ebay…" Sam murmured, shocked.

Ratchet joined the conversation, "If the Decepticons find the All Spark, they will use its power to transform Earth's machines and build a new army."

'Well, isn't that fucking fantastic,' I thought.

Optimus continued gravely, "And the human race will be extinguished." He paused ('Cue dramatic music,' I thought). "Sam Witwicky, you hold the key to Earth's survival."

"Please tell me you have those glasses," the girl said, now very pale.

-------------------------------------------------------------------------------------------------------------------------------------------------------

"Where are you going?" Hermione asked as Harry got up from where he had been eating (in reality, he's been pushing his food around his plate) breakfast.

"Meeting with Dumbledore. He said he wanted to talk to me when I was settled." Harry replied. "Don't expect me in class for a while. I don't know how long this is going to take."

"Alright," Hermione said as she nodded. "Have fun."

Harry walked into Dumbledore's office, looking around the room he hadn't been in for two years. It appeared untouched by time.

The Headmaster frowned as he noticed the young man taking note of all the entrances and strategic places in the room. What had happened to the carefree boy he had known to make him so cautious? What horrors had he seen?

"Harry, my boy, come in, come in." The Headmaster said cheerfully. "Make yourself comfortable. Would you like some tea?" he offered, pulling his wand from the voluminous sleeve of his robes (which, today, for some odd reason, had neon green aliens in silver spaceships on fuchsia fabric). "Or perhaps a lemon drop? They are quite delightful."

"No thank you, sir. I just came from breakfast."

"Ah, pity. How have you been, my boy?"

"As well as could be expected. My friends and family really helped to get adjusted."

"I won't beat around the bush, then. Why did you, in essence, run away from your relatives?"

"First, let me say that I had every intention of returning at the end of the summer; circumstances got in the way. And, in answer to your question, I had to get away. I was feeling rather…smothered and out of sorts."

"What kind of circumstances, my boy?"

"War," Harry replied bluntly. "A war that has been going on for millennia. It has destroyed a planet and which, after thousands of years, made its way to Earth. I happened, or rather, it happened upon me. After all, fate rarely calls upon us in a moment of our choosing."

"Millennia…?" Dumbledore began. "How could that be? And what would destroy a planet?"

"They, and because of unforeseen circumstances, now I, live virtually unending lives."

"How?"

"In order to understand, you need to know our history.

"We are all descended, in some way, from the All Spark. The All Spark has the power to create worlds and fill them with life. One such world was called Cybertron. The Cybertronians are mechanoids that look similar to humans.

"In what we call the Golden Age, two brothers came into power. One, Megatron, was to be the Lord High Protector. He was to be in charge of the military aspect of leadership. His brother, Optimus Prime, was charged to be the Bearer of the Matrix. His duties leaned more to the politics side of the spectrum.

"Then, Megatron became greedy. He wanted the All Spark, and its power, for himself. So, secretly, he started gathering an army of like-minded individuals.

"And so, when Optimus found out what Megatron was planning, he did everything in his power to, peacefully, appease Megatron. Megatron was not to be persuaded. War was inevitable and two factions emerged. The Decepticons, led by Megatron, and the Autobots, led by Optimus.

"The war raged for years. Whole cities were wiped out, utterly decimated. Finally, Optimus had no choice but to launch the All Spark into space and pray they would find it before Megatron. They spread out all through the galaxy hoping they would locate it. And after a thousand years of searching, they found the planet on which it had landed."

"Earth," Dumbledore breathed. "But that still doesn't explain how you have the same life expectancy as them."

"I'm getting there. Continuing on, Megatron had found the All Spark about a hundred years before Optimus' team stumbled upon it. Fortunately for the Autobots, he crash landed in the Arctic. We don't do well in the extreme cold. Our systems just completely shut down.

"And so, Megatron remained frozen until a Captain Witwicky stumbled upon him. The captain accidentally activated Megatron's navigation system and the All Spark's coordinates were etched onto his glasses. When he returned, he was thrown into an asylum for raving about iceman and drawing weird symbols. His glasses and other possessions were passed down by his descendents until they reached the hands of his great-great grandson, Sam Witwicky.

"Sam, from what he's told me, and what Bumblebee has told me, needed 3 A's and $2,000. One of the ways he was planning on getting that money was selling his great-great grandfather's things. He placed them on e-Bay. Bumblebee was sent ahead by Optimus to scout out the planet and find the glasses. Well, we're all connected to the internet, up here," Harry tapped his head. "Thus, when Sam posted the glasses online, 'Bee was able to find him. Unfortunately, so could the Decepticons.

"The night after 'Bee was able to get himself purchased by Sam and his father, he snuck away to send a message to Optimus and his team. About this time, I was flying in a plane over the Atlantic on my way to Las Vegas. The next day, Sam's getting chased by a Decepticon, designation Barricade, through Tranquility, manages to rope his now girlfriend Mikaela into this entire mess, and 'Bee's trying to protect them all at same time. Well, later in the evening, 'Bee manages to kick some major aft and takes Sam and Mikaela to rendezvous with Optimus and the rest of the team who had just made planetfall.

"Meanwhile, I'm taking a walk through Tranquility and stop to admire a car at a dealership, when Jazz jumps down behind me to find an alt-mode. He takes me to alley where this rendezvous is taking place. Long story short, Optimus explains what they are, why there here and we're off to Sam's place to find the glasses."

"Life's never dull for you, is it, my boy?"

"Not at all. And I'm only halfway through.

"We had an entirely to awkward encounter with Sam's parents after which we get the glasses, prepare to hand them over to the Autobots, when this beyond top secret division of the government called Sector Seven shows up. They barge in with radiation meters, scanning the house, the flowerbeds and Sam's dog. Of course, Sam and I smart off and manage to piss the head agent off. He uses his scanner on us and off course our radiation's off the charts 'cause we both had direct contact with the Autobots. They take all of us into custody.

"On our way to wherever they're taking us, Optimus intercepts our little motorcade. He, Jazz, Ratchet, and Ironhide puts the fear of Primus into the agents, and bless him, 'Bee lubricated on Simmons. After Sam, Mikaela, and I handcuff all the agents to themselves and then to a pole, we're all standing around talking about our options when S7 backup arrives. Optimus scoops us up and leads the helicopters and such through a merry little chase through downtown Tranquility. We hide under a bridge waiting for them all to lose the trail. Mikaela slides off of Optimus' shoulder, Sam tried to save her and they both start to tumble towards the Earth, after pulling me off with them. We proceeded to bang off of Optimus' arm, leg and then plummet towards the Earth. Just before we go capoot, Bumblebee makes a spectacular diving catch (he would have made any wide receiver or outfielder jealous). The S7 agents catch up to us and proceed to capture Bumblebee with liquid nitrogen.

"I mention that our systems don't do well in the extreme cold, yes? Well, it's also hurts like the pits. Bumblebee's whining in pain, and Sam's trying his best to stop the agents. But in the end, numbers won out and we're being whisked off to Hoover Dam. On our way, we meet Maggie Madsen and Glen Whitmann who had analyzed the hack that had stolen info from the government on Air Force 1 and at Qatar. It was just total chaos.

"We get to Hoover Dam. Simmons debriefs the Secretary of Defense, a unit of soldiers that had been attacked in Qatar, and our little ragtag group. It turns out, S7 has had Megatron and the All Spark in their custody.

"A little Decepticon had managed to stow away with one of our little group, and proceeded to set Megatron free. We all panic, Sam does some fast talking to get S7 to let Bumblebee go. 'Bee shrinks the All Spark, and we high tail out of there. In an attempt to lose the Decepticons that are now heading towards us, we take the All Spark to Mission City. On our way, we pass Optimus, Jazz, Ratchet and Ironhide. They do some impressive u-turns and our little caravan doubled in size.

"We get to Mission City, minus Optimus who stopped to take care of some Decepticon scum. We're doing the best we can to stop the Decepticons from destroying the entire city, when Will, one of the soldiers decides to airlift the All Spark out of there. Megatron chases Sam, who has the All Spark through a building and knocks him off the roof. Optimus gets there in the nick of time.

"The two leaders had an epic battle, and Sam slam the All Spark in to Megatron's chest. The All Spark is raw power and when combined with one of our sparks…"

"Spark?" Dumbledore interrupted,

"Our spark is our soul, our entire being. Without our sparks, we'd just be empty machines. Anyway, when the All Spark was combined with Megatron's spark, it completely destroyed it with a wave of radiation. And now we come to how I came to be an Autobot. When the wave of radiation reached me, it reacted with my magic. The All Spark did not want to be destroyed. The All Spark couldn't be in an organic vessel, and there was no suitable vessels nearby, so it decide to make one."

"You make it sound sentient, but how can that be?"

"It is sentient, or rather, I am sentient. When I said it reacted with my magic, I meant that it used its power and my magic to completely reformat me.

"But you…" Dumbledore gestured towards Harry.

Harry snorted. "This," he indicated his body, "This is just a hologram, a play on light. My real body is currently in my room looking like a car."

Dumbledore sat in silence as he tried to wrap his head around what Harry had just told him. Surely this was just some big, elaborate prank, right?

"Headmaster, now that you know, I'm going to need your help. When the All Spark chose to reformat me, it used my magic. And I mean all of it. I haven't been able to use magic since June two years ago. So, if you can let my professors know without giving it all away, it would make this whole year easier."

"Year?"

"Sir, to be frank, I'm only here to kill Voldemort and wrap up unfinished business. I'm not here to stay."

The Headmaster nodded. He was still trying to come to terms with all of the information.

"If that is all, Harry?"

"Yes…except that I have to tell you that friends of mine will be dropping by to bring needed supplies every once in a while. I'll leave you to your duties." Harry saluted and walked out of the office.

The office, for the rest of the day was silent. All the Headmaster did that day was stare vacantly at the wall, deep in thought.

---------------------------------------------------------------------------------------------------------------------------------------------------

First off, I wanted to say wow! I never imagined that I would get this much feedback and alerts. So thanks to all of you that reviewed and put me or this story on your alerts. You all can have a stuffed Transformer of your choice. :D *grabs Jazz and Prowl*

Secondly, I hope that the scene with Dumbledore makes sense. I'm sorry if it was a little rushed, but I think, by now, we all know what happens in the movie and I didn't want to draw it out too long. And if you're worried about details, such as the how and the what, it will be explained more in depth in coming flashbacks. I promise.

Now, I want to explain things the way I see how the entire Cybertronian gender, in hope of avoiding flames. If slash makes you uncomfortable, this is not story for you. After all, when there's 1 femme to every 200 or so mechs, the mech-femme pairing is going to be rare indeed. Most (if not all, for the Autobots, anyway) of the pairings will be slash.

So, who thought Revenge of the Fallen was awesome? I know I did.

'Til next time,

Forgotten.
