Disclaimer: I do not own Transformers, it's characters, plot line, or anything associated with the idea. Ownership falls under it's respective companies. I'm not making any money from this, it is merely for entertainment. And of course to improve on my writing!

A/N- This is my first story! Comments are much liked and I don't mind any constructive criticism! Sorry if it's short! As said at the end, it's just an idea! Should I continue or leave as a one-shot? If I continue I plan it to be a Bee/Sam! No likey no read. There aren't enough stories out there that get to the dark side of Sam! ;D This is obviously Bayverse. I saw the Dark of the Moon and now own it. Michael Bay, how could you kill Starscream and Ironhide! T_T Not cool. Oh well, loved the movie anyway! ^_^

Deca-cycle- ten days

"speech" 'thoughts' 'dreams'

Changed

By Silverdart

His breathing was elevated, and he felt his chest heave as liquid fire ran through his veins. His heart pulsed, spreading the pain to his entire body. The cruel laughing of his oppressor resonated through his head, nearly overpowering the sound of his screams. As it became unbearable, he couldn't help but cry out in sheer agony...

Zosimo jolted from recharge, vents straining to cool his overheated systems. He scanned the dark room to find himself in his quarters, safe and sound. Or as safe he would ever be on the Nemesis. Air huffed out his vents in a sigh and he rubbed his crimson optics. This was the third time this deca-cycle that he'd had memory relapses in his sleep. Anymore and he'll be asleep on his own two feet!

Pedes, he corrected himself. Even after months with the 'Cons, he was still using human terminology. Frenzy liked to tease him about it and, therefore, so did Barricade. Cheeky glitches.

Zosimo knew he wouldn't be able to recharge again that night. He never could after his 'episodes'.

Swinging his legs off his berth, he smoothly stood and made a b-line for the wash racks. Crossing the large chamber, he was forced to step lightly as to not wake the other grunts recharging on nearby berths.

Not that Zosimo was a grunt.

No, he had made quite the reputation for himself after his performance in the arena. The thought of his latest brawl made Zosimo grin in delight at the memory of the fear in his opponent's optics. It had turned out very well, with him as the victor of course. All the newly turned had to prove themselves worthy for the Decepticon insignia by battling in a test of survival and skill. Mortal combat, no weapons allowed, just brute force and strategy on the fly. 'Or deception' Oh yes, deception was necessary for his talent. How else would he lure in his prey?

Zosimo activated the wash sensor and water cascaded around him, washing dried energon and system coolants off his chassis. As he scrubbed his black frame, he pondered his position among the ex- humans. They found him to be quite disturbing and blood thirsty, even by Decepticon standards. They didn't know how right they were...

After turning off the shower, he left the shared quarters and continued down a dark corridor towards the firing range. He loved to spend the day shooting his plasma cannon at targets or others. It didn't matter which. Practice was so much more enjoyable when your targets are moving and give you a straight forward reaction when impaled by your bullet. After all, there would be no second chances in the field against the Autobots or those annoying pathetic humans.

'Strange', he thought to himself,' I don't hear any gunfire.' Lord Megatron, Barricade, even that traitorous fool Starscream enjoyed practicing their aim. But more to blow off steam in his mighty master's case. Perhaps they had embarked on another raid. The Autobots have been fighting a lot more fiercely and with more deathly intent than usual. More and more officers had to be rushed to Hook in the med bay or face permanent deactivation.

The reason behind the ferocity was obviously the disappearance of Samuel James Witwicky. The 'bots were particularly close to that insect. Especially the yellow Camero scout Bumblebee.

"What is this strange feeling in my spark. He isn't important. Although I must admit he is attractive...' His optics shuttered as he skidded his thoughts to a halt. Why was he thinking like a hormonal youngling? Probably excess ghost feelings from his past life. But of course, he wasn't an evolved primate anymore. He hadn't disappeared, not really. Just changed.

Autobot Base-Diego Garcia- 5 months after the disappearance of Samuel James Witwicky

Bumblebee writhed in a mental struggle against his darkened dreams

. "Sam! Sam, where are you? Can you hear me? Sam!" A light giggle caused him to whirl around only to meet the glare of two burning red optics. "What have you done to Sam!"

The unknown cybertronian gave no response. "Answer me!" A light shuffle, but still no answer. "Answer me, Primus damn it!" Bumblebee's arm transformed into a plasma cannon only to be slammed onto the black chest plates of the Decepticon.

"Now, I'll say it again" he growled, rage evident in his static laced voice. "Where... Is... Sam?" The other smirked, revealing pearly white pointed denta from behind his lip plates, optics narrowing mockingly. The stature practically screamed 'I know something you don't know!'

Before getting the opportunity to fire, the other leaned forward against his cannon and spoke in an eerily familiar voice into his left audio. "What are you talking about Bee?" It chuckled then hissed "I'm right here."

Bumblebee's sky blue optics widened at the sudden searing pain in his abdomen. Looking down, his face contorted in horror to see his life blood flowing over a red energon blade. Looking to his killer again he was terrified to see the black cybertronian had disappeared. In his place was an enlarged human he knew well, glancing hungrily at the processed energon coating his weapon. Their eyes locked and Bumblebee saw unrestrained bloodlust in the other's eyes, a monster. But it couldn't be. Just couldn't. He strained "Sam?"

Bumblebee awoke with a high pitched shriek, one likely to rouse the entire base and carry on for miles. Vents and air pumps worked on maximum as he tried to calm his frantic panting. He tilted his helm forward, clear lubricant building in his optic lenses. 'What a horrible nightmare'. The door to his quarters pinged, indicating the presence of another on the other side. Bee's frame straightened, quickly wiping away the 'tears' streaking down his cheeks. His radio broadcasted the voice of a woman. "Who is it?"

"Bumblebee? It's Optimus. May I come in?" Optimus Prime's voice was worried and concerned, as it should be. He had been practically a father to Bee since younglinghood, in relationship if not blood. Chirping an affirmative, Bumblebee slumped in sadness as the door slid open and Optimus walked in. Immediately seeing his distressed condition, Optimus went towards Bee's berth and wrapped his arms around Bumblebee's quivering shoulders.

"What's wrong Bumblebee? Did you have a bad flux again?" Optimus was getting worried at this point. Nightmares were rare but did happen among his people. Only after great emotional pain had occurred in someone's life, like the death of a bondmate could cause the simulations during recharge. 'Or the death of a great friend' He thought.

Nodding a yes, the car radio in Bumblebee's chest gave out static for a moment then portrayed the voice of a young boy crying "It was terrible!" Bumblebee's shoulders loosened in defeat. "Maybe if he was... still here... it wouldn't feel so bad!" The put together words were filled with sorrow and pain. Optimus rubbed Bee's arm in comfort.

Optimus felt sympathy for his 'son'. He knew how much it hurt to lose someone close. Just look at he and Megatron before the uprising, as close as brothers. Megatron's betrayal had struck Optimus so deep that he couldn't trust another for a long, long time after. Sighing, Prime suggested "Why don't you go and see Ratchet. He could give you something to help you recharge, or at least get you into stasis. This lack of rest isn't good for your systems, you know." Bumblebee nodded again and allowed Optimus to guide him towards the door. Before leaving the room, he remembered the last part of his nightmare. The black transformer was replaced with Sam, his Sam. What could this mean? What had happened to his close friend, his... 'My maybe more...'

A/N- Should I continue with this idea, or leave it as a one shot? Please review! Oh, and Zosimo is not an OC, as you all have probably already figured out! Sorry if some of the personalities are a bit off! I've only really seen the movies but have read hundreds of other Tranformers fanfics! Keep Bee/Sam alive and thriving! Just to clear up any confusion, the last thought was Bumblebee stating that Sam may mean more to him than he had previously realised... ;D
