The Autobots needed a home after the war of Cybertron, and so they found one. It was a strange planet with strange beasts. In the night, they lost most of their warriors, all of their scientists that were figuring out the food chain, and all but one medic and all but one femme. All that remained was Optimus himself, Nemesis, Ratchet, Arcee, and Bumblebee. The rest were gone.

Before Perceptor died, he created machines, great machines and chains of systems to accomplish one thing: allow the Autobots to survive. The top of the food chain appeared to be a primitive race that relied on bows and arrows and mounts to do their bidding. They did not know what they were called, and Optimus was immediately interested.

Perceptor's inventions resulted in two identical, fully mature avatars that resembled the top of the food chain, the blue and navy blue striped race with sharp teeth and wide eyes always taking in the beauty of their planet. To the Autobots, it could be beautiful, if they could cycle a proper intake.

Ratchet passed out masks that filtered the toxins out of the air, already wearing his. "This is unfortunate," he said softly. Nemesis slapped his mask on and breathed deeply, sharing everyone's thoughts: We can breathe again. "Percy made two avatars, and they are fully mature. Arcee, yours is a baby still, which is rather unfortunate, but can be worked around. They mature slowly outside of their pod. You will wander after Optimus and Nemesis later. Bumblebee, yours is still an embryo."

Bumblebee nodded. Even though Ratchet repaired his throat from where Megatron grabbed him and shook him, he was still quiet. Some things just didn't require speaking, Optimus supposed.

Nemesis clapped his servos together. "So we go in, dream, and become one of them. Got it."

Optimus patted his brother's knee. "It cannot be that simple."

"Oh, it is. Percy knew no one was as smart as him, so he made it so simple Nemesis could do it without help."

Nemesis grinned at his brother. "Let's go check out the avatars."

ooo

Arcee's avatar fluttered her hands and kicked her feet in her tank. She was as nervous as a butterfly sitting in sight of a frog, and Optimus adored her. He loved Arcee's avatar, and he wondered if he and Arcee would end up mated in their new bodies. Nemesis was in love with his avatar.

"Look at him! Oh, he's beautiful!"

The avatar was darker blue with purple stripes instead of navy. Optimus' looked more like the natives, yet that didn't bother any of them. Sometimes the avatar's had minds of their own. Ratchet laid his friends in their chambers, preparing them to connect with their bodies once he laid them out.

"It may be a bit shocking at first."

"Do it," Nemesis chirped as the lid to his chamber closed. He was excited. Optimus could feel it like electricity coursing through his veins, and he had to admit it.

He was excited, too.

ooo

When he woke, everything was different. Everything was the same. There was no change. Everything changed.

He blinked his eyes, touched his arms, his chest, his legs. His strong, strong fleshy legs that couldn't possibly be real.

Nemesis was whooping. "I'm sexy!" He jumped up, staggered, and fell on his butt. Ratchet helped him up, helped both brothers stand. The Cybertronian bodies towered over the native-like avatars, but that was alright.

"I told you it would be shocking!"

They stretched, jogged in place, and then around the room. Nemesis pushed his naked body to the limit, sprinting and jumping and rubbing at his shoulders, his arms in disbelief.

"In the dark, we glow!"

Optimus laughed softly and he focused, making his skin pulse, making the little bio-lights dotting his arms and shoulders and back and legs and face light up with color. "I can glow in the sunlight."

"Whoa!" Nemesis cheered, making his lights pulse and flicker in a dizzying manner that left him breathless from awe and from the effort. "Beautiful. Is that appropriate to say? I am beautiful."

"And you are late," Ratchet growled. He shoved clothes and packs at them. "Cover yourselves, will you?"

Optimus stepped into the large shorts and buttoned the shirt up, chuckling softly. They knew about clothes. The Cybertronians had capes and dresses. Those were clothes. Ratchet just made shirts and shorts.

Nemesis dressed slower, still admiring his body before he touched his brother's hair and tugged on the long braid. "You'll never guess what this does."

Optimus, when he was dressed, played with his brother's hair. He moved the thick black hair around, then looked at the long braid that fell to his brother's aft. He lifted it, marvelling it.

"Touch the end."

The hair moved back and tendrils, soft tendrils that pulsed with life, curled around his fingers and he gasped at the energy there before the tendrils released him and tucked back into the hair.

"It bonds us to mounts."

Optimus made a soft sound. Nemesis picked up on things immediately after glimpsing things. Optimus had to dedicate himself to hours of study before he wanted to call himself understanding.

"They have a native language you must learn." Ratchet watched them. "Please don't get yourself killed, and remember the goal: finding a place to call home."

Nemesis and Optimus nodded in agreement and focused themselves on the mission. Mostly.

ooo

They ran together, climbed trees and sprinted through the dirt and bushes and plants that were larger than they. They spooked small animals that bleated and chirped, and they watched giant things fly in the sky. Nemesis wanted one as a mount. He was drawn to them. Optimus would rather his feet stay on the ground.

They had only left base camp an hour ago, and had no reason to think that they were being watched, so they missed the female hiding herself in the trees.

Optimus helped his brother avoid the larger animals that had hammers for heads and muscular, armored bodies that could surely kill them. Feathers danced on their heads, communicating and making them almost predictable if they could understand the meaning. Nemesis called them territorial, and Optimus had to agree after the beasts chased them past some invisible line that stopped the large male from following.

They laid on the grass, panting heavily. Nemesis was laughing soon, elbowing his brother. "You were scared."

"You screamed like a femme in heat."

"You scream like a femme regardless!" Nemesis jumped at his brother, wrestling him.

The female grew interested, edging as close as she dared. They were just like her, but with ridiculous things on their bodies that seemed to serve only one purpose: to make her laugh. There was a ripping sound and the taller one's chest was revealed as the fabric came off and fluttered down to the ground like a wounded animal.

"Ahh, ripped my shirt, you aftport." Nemesis shoved his brother's chest, ripping his shirt off next. "Maybe your shorts should go next." He licked his lips playfully.

"You touch my shorts, and I will bite you." Optimus flashed pearly white, deadly teeth in a grin, making Nemesis pretend to shudder. "Exactly. Be afraid."

Nemesis' ears flattened against his head and he lashed his tail. At first, the tail had been weird and Nemesis refused to be anything tailed, but he got used to it. It was actually pretty cool. "You're not the only scary one in this forest."

Optimus opened his mouth to say something, but an arrow buried itself into the ground between them. Both brothers stared at it for a long time before they looked up at the young female.

"Welcome to Pandora, Sky People."

Nemesis leaned closer to his brother, biting his ear. Optimus hissed, but listened to what his brother had to say. "I'm guessing this happened before."

"Let us not make the same mistakes those before us made."

They looked into each other's eyes and nodded once.

"Agreed," the muttered and they walked closer to the female. Optimus addressed her. "Ah, who are you, child?"

"Ka'tai, daughter of Jake and Neytiri."

Optimus hesitated. "I am Optimus Prime, and this is my brother, Nemesis."

"Father will be most interested in seeing you. He thought we would get no human visitors."

"Well, he's right, Katie. We ain't humans."

The young girl snarled. "Not Kay-tee. Kah-tie."

Optimus elbowed his brother, hard, between the ribs. The larger male yelped. "Apologize."

"Sorry, Ka'tai," Nemesis murmured. He climbed up to her limb on the tree, watching her. "So, how do you know English?"

"Father taught me. He taught everyone. Come. He desires to meet you."

Nemesis landed beside his brother, and they watched her run through the trees. "What have we gotten ourselves into, Optimus?"

"A whole new world," Optimus said and he grinned at his brother before following Ka'tai. Nemesis ran after him.

So I watched Avatar last night and I'm imagining Optimus and Nemesis going through this and all the funnies of what would happen. At one point in the story, I want the chief to be greeting them in their native language and Optimus will turn to Nemesis and say "What did he just call me?" and Nemesis to reply "I think he called you fat" XD If me and my brother get in some pretty interesting arguements during PE, imagine how split-sparks will respond! XD Don't hate me. I wanted to take this out for a spin. XD
