Trapped Together

Chapter 1

He was strapped to the medical table unable to move. The pain he was in forced him to stay still. Multiply medical tubes where attached to his body which were pushing energon into him. Megatron had taken care in making sure that he would be lying like this for some time.

His memory of being tortured by Megatron were burled all he remembers is the pain, breaking noises and the deep cuts from the device Megatron used on him. The slightest movement he made forced pain to travel all though his body.

He lay still resting, he didn't know how long he had been lying like this but it felt weeks to him.

He heard a noise and then footsteps...someone had entered the Medical chamber, the figure came towards him. Even with his eyes was closed Starscream knew who it was. He immediately opened his eyes and found Megatron looking down at him smiling.

'Resting comfortable Starscream? Despite the extent of your injuries my medical staff, assures me that you will make a rapid recovery'.

Starscream forced himself to sit up a bit 'Hopefully has ever bit as rapid as your raft is swift' saying those words caused more pain and he started chocking.

Megatron began laughing as he was enjoying watching Starscream suffer 'and how swiftly things change, to think but a short time ago it was YOU who was standing here! While I was laying there right after your failed attempted to terminated me!'

He felt his body begin to shake, he knew that he wouldn't be able to survive another torture session with Megatron but his leader didn't do anything instead he drew closer to him and whispered 'But know this dear Starscream are positions shall never again been reversed'.

Starscream watched him leave, he felt angry building up within him. He would make Megatron pay for what he did to him and...He knew exactly how to do it. He ripped out the tubes attached to his body and climbed out of the medical table, more pain came but he didn't care. He knew of something that would heal him and also bring him unbelievable power, which will allow him to destroy Megatron and once he is dead the Autobots would be next.

He opened the doors and he found Knockout standing outside, he turned to face him.

'Starscream, have you lost your sensors! You haven't fully recuperated'

'I feel FINE Knockout never better! You're a brilliant fascination now GET OUT OF MY WAY!' He pushed the medic away and headed towards his prize.

...

Once he made it to the corridor, he looked around the area first making sure that he was alone and then he entered. He was getting close to it and not a moment too soon he felt that he was going to collapse.

The shard was close; before Megatron came back he hid it beside the lift doors. When reached it he looked once more encase someone was around and once he was satisfied that he was alone, he reached out and grabbed the Energon spike pulling it towards him.

'Ah...dark energon may have replenished your strength master...But how could you forget, that you never reclaimed your ordinarily shard!'

The memoir of when he found Megatron after the space bridge explosion, flashed before his eyes, he smiled to himself remembering when he pulled the shard from his chest and watched his eyes go dark

'Once the blood of Unicorn flows though my veins...are positions shall be revised'. He smiled once more as he held the shard tightly in his hands.

Unknown to him Knockout watched as he took the shard, he was interested in what he was going to do with it. He knew that he should alert Megatron but Knockout had to admit he was curious about this dark energon power. He never actual witnessed it himself so he made the decision that he would follow him and see how he plans to destroy Megatron and then he will decided if he should help Starscream or warn Megatron.

Autobot Headquarters

Optimus entered the control room. He found Ratchet looking over the computer, when the medic saw him he quickly asked him to take a look at what he found.

When he examined his readings, he discovered that there was dark energon moving at high speed towards an area he knew all too well.

'I had hoped that my growing expertises on the subject would remain purely academic, but though faint it's clearly a dark energon signature and it's moving fast'. Ratchet said.

'Megatron...'He had been waiting to see when the Decepticon leader would make his move and apparently this was it.

'Where he fined more of the bad stuff' Arcee said as she joined them

'And what's he going to do with it recruit a new army of the undead' added Bluckhead

'We cannot rule out the possibility epically since Megatron seems to be heading to a familiar site'. He knew it alright this was the place where he and Bumblebee battled Skyquake.

'Autobots get ready were going in'.

...

Starscream flew over the rocky area; he was close now to the site. Memoires of the battle between Optimus and Skyquake filled his mind, he had been so close to having Optimus destroyed but his plans were ruined by the other Autobot Bumblebee and the human that he once held captive.

He arrived at the sight and transformed to his robot form and approached the grave of Skyquake 'Ah the grave site of the mighty Skyquake...so quick to reject my authority while you lived, but as the first of my reanimated warriors you shall bow to my command' he then took the dark shard and broke it in half.

He threw one piece at the grave of Skyquake and the shard disappeared below the rocks. He could feel the power of the dark energon building he knew it was time. He plunged the dark energon shard in his chest, there was pain for a moment but it soon passed he felt a great surge of energy building him within he felt power and strength

'Yes the power of dark energon...BE MINE!' The power exploded within him

'YES Symbiosis I can FEEL IT!' He let lose his power and targeted it straight towards Skyquake grave he knew soon that he will awake and once that happens he will watch as Skyquake defeats Megaton and then HE will be leader of the Decepticon.

...

Optimus gathered the group together once Bumblebee came back with the children.

'Megatron has barley emerged from stasis and it seems he's already making up for lost time. Bluckhead, Bumblebee, Ratchet prepare to roll out'.

'Me!' Ratchet said in surprisement.

'If we are dealing with Dark energon I may require your expertises, Arcee...'

'Bridge operated got it' she went towards the bridge controls and activated the ground bridge. Optimus and his group approached the bridge changing into their vehicle modes first; the all speeded their way in and within moments there were transported away.

The group emerged from the bridge and turned back into their robot modes. Optimus stood for a moment looking at his surroundings; it was indeed the very place that he and Bumblebee battled Skyquake. He knew that Megatron must be trying to resurrect him using dark Energon and if he did this Skyquake would be more deadly than before.

He ordered the others to be on guard, he knew that Megatron would not come here alone. The group made their way in deeper. The grave site of Skyquake was just around the corner but what they saw surprised him and the others for it was not Megatron who stood before them but Starscream.

Optimus could see that the Decepticon was badly damaged likely from being tortured by Megatron. He knew that Starscream would use Skyquake to destroy Megatron and any other foe that stands in his way. But the leader of the Autobots wasn't going to let that happen, the undead bots he fought before were hard enough and he couldn't risk anymore from being resurrected.

'Rise, Skyquake! RISE' Starscream shouted.

Optimus could already feel the power of the dark Energon beginning. 'Starscream!' he called.

The Decepticon turned to face them and back away in surprisement 'Autobots!'

'Stand down' He pointed his gun directly at him.

'You stand down!' Starscream fired a rocket straight towards him and the others. He orders them to take cover and the 4 of them jumped out of the direction of the rocket and hid behind some rocks.

'YOU cannot harm me while Dark Energon flows though my veins'

But Optimus just stood up and fired a shot straight towards him. There was a loud bang, a cry and then something hard hit the ground.

He watched as Starscream looked and found that his left arm lay in front of him. Optimus energy weapon blasted his arm clean off. He had no way to escape.

Starscream quickly ran and grabbed his arm running towards Skyquake grave and hiding behind some rocks nearby.

'You clipped his wing he's grounded' Bulkhead said. Optimus nodded towards him and then he and the others rushed towards his position.

...

Knockout looked down from the rocks and watched as Starscream threw the dark energon shard into the grave of Skyquake

'So that's his plan'. He knew from Megatron that the energon had the power to bring back the dead but they would be nothing but empty husks with only one purpose, to destroy everything in its path. He had heard that Skyquake was a deadly opponent in battle and with the power of dark energon in him he would be even more deadly.

A noise comes from his left. He looked and found a ground bridge and opened up and 4 figures stepped out. It was the Autobots...he saw Bumblebee, Bulkhead, Ratchet and more importantly Optimus Prime. He smiled when he saw the leader he had not seen him in a while. He started remembering the night when they first met he whistled at him and told him he had sweet rims. This was true, he loved his vehicle mode (Optimus had good taste) the truck was big, powerful and gorgeous to look at. But when he saw him turn into his Robot mode his mouth fell open. He always prided himself in being perfection but Optimus was something else.

He remembered whispering beautiful under his breath; Optimus was special it literally was love at first sight. He watched as the great Autobot Leader started walking towards Starscream his lovely hips swaying as he moved, he wanted to taste them.

'You're so beautiful Prime but don't worry you and I shall meet in private someday'. He then watched the Autobots confrontation with Starscream. Knockout was shocked when Optimus blew off the second in command's arm he thought that the Dark Energon would make him unstoppable but that's what Megatron said as well but the Autobots managed to stop him. He saw Starscream run and hide behind some rocks.

'I better help him'. He got ready to jump down and attack but just then he heard voices he looked saw the 3 humans that the Autobots befriended. The female one was screaming about losing something. He found human's to be annoying but he also admitted that they knew how to make sweet rides. Then an idea came to his head, he knew that the Autobots would get the humans to get to the ground bridge and that meant that he had an opportunity to get I inside the Autobot base.

'Starscream, do you read me!'

'I'm busy!'

'I know the Autobots got you pinned down'

'What! How do you know?'

'I'm watching you right now, no time to explain why I'm here I need you to keep the Autobots busy'

'Encase you haven't noticed they shot my arm off'

'Look just keep them busy long enough for me to get to the humans'

'What! The humans they are here'

'Yes and the Autobots would want to get them out of danger, I can rush towards the ground bridge and arrive at the Autobot base it's only guarded by 1 and I can easily take her'.

There was silence for a moment...'alright but make it quick I summoned for a ground bridge it will be here soon.

'Understood...' He ran, jumped towards where the Autobots first landed making sure to time the jump with the Rocket that Starscream fried at the group. He pressed his body against the wall and looked around the corner and waited for the Autobots to active there bridge.

...

Optimus fired another round at Starscream who in turn ducked out of the way. He was about to run towards the Decepticon ending this fight once and for all when he heard a voice shouting, he knew who it was. He looked back and found Miko shouting at Jack (What are they doing here).

'O no!' Bluckhead said.

Optimus heard his comm. Link come on line 'Base to Optimus the kids are missing'

'We have a visual, send the ground bridge immediately'. Within seconds the bridge appeared but then another noise came behind them and the group saw that Starscream had summoned one as well.

'Two? YOU THREE into our ground bridge NOW!' Ratchet shouted towards the humans. The children started making started to run but then suddenly the Autobot's found there selves thrown to the ground, Starscream had fired at them while they were distracted.

Optimus felt the impact of the explosion burn his metal body, his vision was burred for a moment but he shook it off. He needed to focus on getting the children away safely. He looked up and saw them running towards the bridge but then something caught the corner of his eye, it shined for a moment.

He looked and saw a familiar Decepticon hiding nearby. It was Knockout and he was staring at the children as they drew closer to the bridge.

'No...' he knew would try and attack them and also run into the bridge (Not if I can help it).

The moment Knockout rushed towards the children he did the same. The Decepticon ran until he was inches from the bridge. The children looked in time to see him coming and they screamed for help. Optimus jumped and tackled Knockout to the ground but the 2 rolled and disappeared into the bridge.

Ratchet got up in time to see Starscream disappear into his ground bridge. He found that Optimus was gone and he saw that the children were still with them. He was about to call to them to tell him what happened when he noticed something happening. The energy from the bridges started intertwining with each other.

'Ratchet what's happening' Bluckhead said.

'The duelling ground bridge portals must be feeding back on each other!'

'Optimus!' Bumblebee cried as he rushed towards the portal but as soon as he reached it an explosion of energy erupted sending him and the others flying back and crashing to the ground knocking them out. The whole area shook, with the explosion.

...

Starscream hit the ground; he knew that he was back on the ship. He was relieved to be back (that was too close). He looked around and found that his arm was missing (dammit I must have dropped it). He looked up a found one of the Decepticon soldiers standing looking at him. He quickly got up and shouted 'Not a word about this...to anyone!'

He quickly left the room and once outside he pulled the shard from his chest, his plans were ruined by those Autobots, he didn't even know if Skyquake raised or what happened to Knockout but there was one thing he did know he had to get back to the med bay he couldn't afford to have Megatron know what he was planning.

...

Knockout felt pain but he was alive; he remembered chasing after the humans and the next thing he knew he was tackled to the ground and then nothing. He opened his eyes, his vision burled for a second but the first thing he saw was a red chest plate. He shook his head, clearing his vision but then found that he was lying right on top of the Autobot leader.

Optimus optics was dark and he wasn't moving. Knockout lay still he found himself unable to move, all he could do was stare at the sleepy Prime. A voice in his head started speaking to him-(you could end this war right here, you could kill him the Autobots would be lost without him, the Decepticon would win if you pull the trigger).

But then his eyes trailing Optimus Prime body. He was on top of a bot that he admired, the beautiful Optimus Prime was out cold he had him at his mercy, he could do anything he want with him. Then another voice spoke in his head-(It's too ground an opportunity to waste).

He smiled that voice won the argument. He began to move his hands along body of the Prime; he wanted to feel, every piece of metal.

When came across the hips, the blue metal was shining he looked up again making sure that Prime was still out and then he placed his hands on them and squeezed (god these do feel good), He leaned forward and gentle placed his lips on them, kissing them at first but then moving his tongue along them.

'O don't you taste good' he thanked anyone out there for this moment. Once he pulled away from his hips, he wanted to taste something else. He leaned forward and moved his hand to retract Prime's battle mask, he took a deep breath at first, hoping that he wouldn't wake up, still no movement. He then slowly slide the mask away to revel the beautiful lips of Optimus Prime

'Don't those look sweet' he also had to admit Optimus looked cute asleep, he moved again.

'I'm going to enjoy this' he leaned forward so that his lips could meet Prime's he was finally going to taste them, he waited so long for this moment. His lips were inches from his and when he finally went to place them on Prime something grabbed his neck and squeezed hard.

'Don't even think about it' the voice of Optimus Prime spoke and Knockout saw that his optics were shining brightly again.

'Ah...can't blame a bot for trying, right'

Optimus threw him and he hit against the wall hard 'Ah... was there any need for that sweet rims'. But Optimus was in no mood to talk and he stood up and brought up his blaster.

Knockout brought out his staff and was about to attack when he heard something a voice saying 'Guys are you ok', he knew it belonged to that human girl

'Ahh what just happened' Bulkhead said as he and the others stood up and they were looking around. But something wasn't right Knockout could see that the stupid Autobot was looking right at him, so why wasn't he attacking.

'I can't be certain but if 2 ground bridges sent to the same coordinates crossed streams, the feedback loop could have trigged a system over load' Ratchet said as he and Bee stood up.

'Could more like it did' Miko said as she brushed the dirt off her.

'But Optimus made it through right' Jake asked

This confused Knockout even more, they couldn't see him. Optimus called over 'Bluckhead I'm here and so is Knockout!' but he didn't answer him and instead they talked as if he wasn't there.

'Arcee did Optimus make it back to base'

'No! You don't see him'

'There's no sign of him'. The group looked at each and panic began swelling up within them.

'Ratchet I'm here!' Optimus shouted again but nothing.

As soon as Optimus looked away Knockout rushed for a attack, but not towards Prime but towards the others (have to get out of here) he ran shoved his staff right at Ratchet but instead making an impact the staff went right through him as well as he, which caused him to fall to the ground.

'What the...' he got up and attacked again but this time at the yellow bot but nothing again his staff just passed threw him.

'Ok this is new...'

The group continued talking. 'Ratchet do you think Optimus got transported to the Decepticon ship'

Ratchet stopped dead in his tracks as if he was thinking about what if that happened but then he eventually spoke 'No if Starscream didn't arrive in our base the most likely explanation is a dislocation, Optimus may simply have been bridge to an untended destination'

But Knockout didn't understand he was in the same location so why couldn't they see or hear him. The next thing he knew he was through to the ground, something stuck him from the side. He found himself lying on the ground, his hands pinned down and...Optimus Prime looking down at him

'Listen to me Knockout! Something has happened to us, I don't know what but it seems that the others cannot see or hear us, were in the same situation so I suggest a truce until we figure out what is going on'

'A truce?'

'Yes if we are to get out of this mess, do you agree?'

He thought about this for a moment, working with Optimus prime this was a day to remember but they were stuck and he didn't see the reason in the 2 of them fighting (well not until this whole business is over).

'Alright sweet rims you have a deal'

'Good but...will you please stop calling me that'

'Then what should I call you sweet or rims you chose'

Optimus gave a grunt noise in annoyance and went to get off him but Knockout then rapped his legs around his waits.

'But a...can we just stay like this for a bit longer, I think you really hurt my back and as a doctor I know that's it's not wise to move the patient if he is injured 'he smiled once more into Prime's beautiful eyes. Optimus shot him an angry glare which immediately made Knockout let Prime ok.

Optimus then pushed off him 'Get up' he said and he went over to listen to the others.

'What is it Bee' Raphael said.

Optimus looked towards the group as they turned and found the yellow bot pointing towards the grave of Skyquake it was empty.

'How did we miss Skyquake rising and shining?' Bulkhead said

'It would seem Starscream got what he came for... but we have more important things to worry about. We have to get Optimus back safely, Arcee...bridge us back to base' Ratchet said.

Knockout approached him as he looked down at the empty grave. 'Well at least this situation isn't all bad'

'What makes you think that?' Optimus said as he stared at him.

'You and I can still touch each other' and he winked at the Autobot.

Optimus grunted again and then he watched as the others started making the way back to where the ground bridge original opened up.

'Maybe if we travel back with them through the ground bridge it might get us back to normal'

'Hmm let's try it, but promise me one thing, don't let your friends fire on me the moment me appear'

Optimus nodded to him and then the 2 started walking behind the group. They could hear them talking about theories on what happened, but then one of the humans told Ratchet about Knockout.

'What! You mean to tell me that Optimus and Knockout both got transported together!'

'Yes Optimus saved us from him and then they both went through' Jack said

'O that's just perfect; the 2 could have ended up in the same destination'

'But what was he doing here anyway' added Bluckhead

'Let's worry about that later I just want to get Optimus back home safety'

'Aww they really love you don't they and who can blame them, they're very luckily to have a smart and sexy bot like you in charge'.

Optimus was about to say something when suddenly they heard something, a loud scream erupted in the air which seemed to be coming all around them.

Both Knockout and Optimus looked left and right looking for the cause. But the only thing they saw was the Autobot's who now disappeared through the bridge. They didn't hear the scream.

'Hello...'Knockout said but no answer came. He started backing away along with Optimus and the 2 brought up there blaster ready to attack anything that moved. Knockout heard something in the distant; someone was moving around above them.

'Come out who ever you are don't be shy'. He didn't know if it was another Autobot or a Decepticon but he will shot whoever comes here him. He looked behind him...nothing.

Optimus was looking up trying to see was the moving above them

The scream came again this time louder. 'Alright...whoever you are, show yourself!'

'Quiet knockout we don't want to give away a position' Optimus said as he moved away from from.

But the Decepticon wouldn't listen and shouted again 'I said COME OUT! What are you scared'

The scream then stopped and nothing but deadly silence surrounded him. Knockout was very nervous now it was too quiet for his liking he really wished Breakdown was here right now. He back away again looking all around him for the cause of the scream, he felt his body begin to shake but he was a Decepticon whoever this was he will make him pay.

He looked once more over to Optimus when a loud noise suddenly came behind him and he felt the ground he stood on shake.

Whoever this was has finally made an appearance, he turned slowly to face it but what he saw caused him to cry out and step away in fear. In front of him stood Skyquake the undead warrior. Starscream had brought him back from the dead.

'O Slag...'
