A/N

I did not think this chapter would be as long as it turned out to be. Not sure if it's a fitting ending but the trilogy does end here. I hope you enjoyed it. Please, read, review, and tell me what you loved about the series and if a sequel series should be released. I'm interested in what everyone else thought about my weird little series. It's hard to believe this all started from a weird little idea I had one day.

World Beyond Time

All are one

A sudden rush of emotion and pain surged through his system and sudden Optimus was wide awake. He was gasping, staring at the ceiling. Everything was strangely clear but soon filtered into normal view. He slowly turned his head to the left. The room came into view slowly. He was in a medical office. The tools were all put away though. Optimus sighed, shutting his optics. Suddenly the memories came back and he sat up, looking quickly around again.

"He's up!"

Optimus perked, quickly meeting the eyes of Sari. She was resting on Bumblebee's shoulder. Bumblebee was holding up his head with his hands, elbows resting on the desk. Both had a smile on their face. Optimus placed a hand to his head. His processor ached. Bumblebee stood up straight. The door opened and Ratchet came in. The medic offered a fake grin.

"Feeling better?" Ratchet asked, moving to a computer console to check results.

"Not really. Just really tired," sighed Optimus. "How long have I been out?"

"Since you arrived, about three hours," Sari instructed.

"Since I arrived?" perked Optimus. "Right, I was…"

"World jumping again," smiled Sari.

"Not of free will," sighed Optimus.

"What happened?" perked Bumblebee.

The memories played slowly before him, reaching the ending when he finally passed out. Optimus sighed. They dropped him off again. The image of Prowl, Perceptor and Hot Shot flashed slowly. He didn't get to say anything to them this time. Oh, how he'd missed them. He shook his head. Everything hurt. The memory hurt more than anything. The memory of what this world was without him. He turned back to Bumblebee and Sari. The two were practically leaned in, waiting for another story. He shook his head.

"I'd rather not," he answered quietly, slowly getting up off the berth.

Sari and Bumblebee sagged a little, exchanging glances. Sari sighed, turning back to Optimus. He didn't have the same look as last time when he came home with a smile and more than willing to tell a long tale. He looked broken and defeated, the first time she'd seen him look this way. Optimus straightened up, moving for the door. Ratchet didn't bother to stop him, until the young Prime met the door.

"He left you something," the medic offered.

"Who left me what?" perked Optimus, glancing back.

Ratchet pointed to a counter. Part of it had been cleaned off, leaving a single item on it, a black chip. Optimus stepped over, lifting the object off the counter and looking it over. Sari and Bee had leaned again, ready to learn what the mystery item was.

"Vector left it," Ratchet explained. "Said it was your going away gift."

"Going away?" whispered Optimus, rubbing the chip.

A button clicked and the device came to life. A light flickered, revealing a small video hologram. Optimus smiled a moment, watching the memory replay. The four of them arguing over what to do. It shut off once the memory was over. Optimus nodded, closing his hand around it. A goodbye gift.

"So that was it," mumbled Optimus, nodding. He began for the door again.

"Will we ever know what happened?" gasped Bumblebee, stopping Prime at the door.

Optimus looked back at them. He still could see the changed world before him. He could still see Sari disappearing before his very optic. He could see Sonic Blast's evil grin. Hear his twisted laugh. Feel the touch of time. Optimus shook his head, leaving the room.

The compound seemed bigger than before. He moved through the halls aimlessly but quickly. He didn't have anywhere to go. He just couldn't stop moving. He'd been moving for so long. There was a pain in his spark as if something was missing. Some open space, that's what he needed. He knew where to go now and soon found himself out on a balcony overlooking Cybertron. He leaned on the railing, deep in thought.

"Optimus?"

Optimus straightened up, turning around. It was Ultra Magnus. The last Prime had seen of him was before Sonic Blast had finally showed himself. That seemed like so long ago. Optimus offered a smile and a salute but Ultra Magnus waved it off, stepping forward. It was strange, Prime thought, for Ultra Magnus to be approaching him in such a fashion.

"Can I help you, sir?" gulped Optimus, unsure of the leader's presence.

"There's a matter I need to discuss with you…" Magnus nodded.

"About?"

"A private matter," smirked Magnus, stepping up beside Optimus. "Something about other worlds."

Optimus sighed. "I understand."

"Not just that, Optimus," he nodded. "I'd also like to talk about your future."

"My future?"

Magnus nodded, taking his leave unexpectedly. Optimus sighed, then smiled. Future. Magnus knew what Optimus was, even in the other worlds. The young Prime perked. This couldn't be about…no, Prime thought, that position was completely unrealistic for him. Or was it? Optimus shook his head, looking out over Cybertron again. Impossible.

Suddenly, something called out to him. It sounded so distant and faint he wasn't sure if it was in his head or not. He shut his optics, listening. It was growing closer but still ever faint. The pain in his spark spiked. He didn't cringe. He simply slowly opened his optics. A white room. It was no longer surprising. Three imaged before him, fuzzy but familiar. His counterparts.

"The connection is dying…" one whispered.

"Our communications will end…"another added.

"But…" gasped Optimus. "What am I supposed to do now?"

"You are ready…" the last replied, Perceptor's Prime.

"Ready?" repeated Optimus.

"For the title you were created for."

"You will do well with all you have learned."

"Is it really over…all of it?" whispered Optimus. "I didn't even get to say goodbye."

The three Prime's exchanged looks and turned around. Their images faded slightly. Optimus perked. It was a strange feeling, rising in him. Out of body. He was no longer with himself, in his world, but peering into the others. He stood beside one of the Primes. Looking ahead, he smiled. It was the Autobot Brothers.

"C'mon Prowl, just one peek!"

"Back off, Side Burn!"

Side Burn was chasing Prowl around a room. A base it seemed. X-Brawn sat offside, laughing. Optimus smiled. Prowl stopped directly in front of him. Optimus perked, holding his breath. The bot was so close. Prowl was looking practically straight at him.

"Help me out, Optimus!"

"Come now, Prowl…"

The young Prime looked up. The Prime he was standing beside had replied. Once his sentence was finished he glanced at the young leader. The young Prime suddenly felt so small. Prowl's Prime stepped forward, vanishing. The image of the world vanished with him. The young leader felt a sudden pressure, stumbling backward, as if the world was crumbling around him or if he was ghost looking at the world of the living. It certainly felt that way.

"Hot Shot, calm down!"

The voice sounded familiar but he couldn't peg it. Optimus spun around, suddenly present in a new world. A bot was looking around. Blue, red visor. He seemed familiar still. Optimus perked. Hot Shot marched into view, stepping up the bot.

"I am calm, Red Alert! I'm fine."

"I disagree."

"Well who asked you!?"

Optimus felt his spark ache. This hurt worse than not saying goodbye. He could only see and hear them. They could not return the favor.

"Enough, you two."

Optimus glanced up. His counterpart had spoken. The two squabbling bots stopped. Hot Shot crossed his arms, turning away. Prime could hear kids laughing. Hot Shot's Prime turned toward the young leader. Another feeling of inferiority. The Prime stepped into his world, vanishing with it. Optimus felt alone.

"Is Perceptor around?"

Optimus perked, turning around. Another world appeared before him. He recognized this one. He saw Rodimus Prime moving around quickly, storming passed Ultra Magnus and Kup. The two bots sighed, replying together with a no. Rodimus groaned, shaking his head and waving them off. As the two left, the poor leader slumped into his chair.

"Why did he give me this job?"

"Tell me about it," sighed Optimus.

Rodimus perked, looking around. Optimus stumbled away from the leader, colliding into something behind him. Looking up, it was Perceptor's Prime. He motioned for silence. Optimus moved away, turning to look at the bot properly.

"Silence here. Wielding the Matrix, Rodimus may be able to hear us."

Suddenly, the door was thrown open. The young Prime turned around, watching Perceptor running into the room. The door was shut by someone behind him. Rodimus stood up, rounding his makeshift desk.

"Where have you been?"

"Lost track of time."

"Perceptor…" whispered Optimus, stepping forward. "Of all the bots in the worlds, a little scientist like him?"

"A one in a million chance," offered the older Prime.

"Can I just do…one thing here of all places?" begged Optimus.

"Which is?"

"Say goodbye…to him? I just want to say goodbye to someone!" shouted Optimus.

Rodimus perked again, looking around the room. Perceptor tilted his head, watching the leader look around almost hysterically. Perceptor glanced around himself. There was nothing that seemed to be gather the leader's attention. Perceptor sighed.

"Everything alright?"

"Swore I heard someone…"

"Who?"

"Prime…"

"The Matrix acting up."

"Not that Prime."

Perceptor perked, taking a second look around the room. Rodimus sighed. The young Prime watched them end their search. They both looked disappointed at the room yielding nothing. Optimus shook his head, turning to the older Prime.

"Did you not get to say goodbye? Do I not get that right?" he snapped.

"Do as you wish," the older nodded. "I will not stop you."

"Just this once," hummed Optimus.

"Say goodbye."

Optimus turned back to the world. Neither of the bots seemed to have truly given up. They were looking out, almost expecting something to happen. The young Prime stepped into the world, feeling more attached to it. Only Rodimus could hear him, he reminded himself. He smiled lightly, nonetheless. He stood right before them.

"Don't say anything just yet," he offered.

Rodimus didn't perk, simply glancing to where Prime was standing. He couldn't see him, but could hear the voice as clear as day. He sighed, giving a slight nod. Perceptor stepped forward, watching the leader now.

"Can you just tell him goodbye for me…" whispered Optimus, looking at Perceptor. "Didn't get to say goodbye to anyone…I just want one…just one…"

Rodimus smiled, nodding. He turned toward Perceptor. The scientist glanced between the leader and the rest of the room. He didn't understand. Optimus stepped forward, between Rodimus and Perceptor. It was a perfect illusion for him. It was almost as if the scientist was looking at him.

"He says goodbye," Rodimus nodded.

Perceptor stopped. Optimus mouthed the words himself. Goodbye. He thought he'd never say those to his three friends. A smile slowly crept onto Perceptor's face. He nodded, shook his head, then nodded again.

"Goodbye, Prime…" he gasped. "Good luck finding your place in your world."

"Goodbye, Perceptor," hummed Optimus.

Rodimus smiled, nodding to Perceptor who gleamed with pleasure. Optimus sighed, closing his optics. Reopening them, he found himself back in his world. Alone. He nodded, looking out over Cybertron again. Goodbye. He smirked.

Like this was hardly the end.
