Tried a TFA drabble based off a thought/idea I had when reading about TFA Cyclonus.
====

You had been resolute and steadfast in your mission.
You had aligned yourself to the Decepticon leader Megatron although for you he was wrong.
All wrong.
This was not the Decepticon leader. Not in your optics.
You ended up falling a great distance into a place known as New Kaon, your damaged body being repaired by those who resided there.
Centuries started to go by.
Senseless, purposeless centuries.

Cyclonus noted just how nihilistic he had started becoming.

Centuries became millenia and Cyclonus watched himself become a nihilistic, dispassionate mess. 
Where did his passion for the Decepticon cause go?
Probably eroded away after spending so long with these primitive ‘cons.
You didn’t get along well with Oil Slick but that was okay.
You knew what was going to happen to him.
The rest of Team Chaar were manageable as long as you avoided prolonged exposure to them.
So it probably didn’t come as any surprise that when that foolish leader Megatron failed Team Chaar broke up. Everyone bar Strika and Oil Slick were replaced.
Including you.

Though by that time you had developed a rather apathetic personality and you wern’t at all bothered by it.Although that bothered you more than being kicked out of the team.
Even then it didn’t bother you enough to be bothered enough to do something about it, and that bothered you further but now your processor hurt.

You had to do something about it.
You were proud and strong once, leading the charge against Autobots at your true leaders command.
Feeling there was no hope for yourself now, the only hope you had was to prevent any of this from ever happening.

You chose to wait.
It was all you had right now.
Nihilism and apathy threatened constantly to take back the twinge of hope you had at altering your situation. It was hard to hold them back from smothering the tiny bit of hope left in you.
You watched from afar as attempts were made and thwarted at freeing Megatron from where he had been imprisoned.
You had even been brought along on one.
It failed.
Not that it mattered.

Time was a cruel mistress and the term 'life cycle’ felt appropriate as Cyclonus felt his life cycling through the same days, over and over again on a non-stop replay.
So long had passed that by now even your swords had rusted away until nothing but the hilt remained of them. Although you had left a majority of one sword’s blade in a small Autobot’s back. That was a good hit.
Before you knew it, missions became fewer and fewer.
Free time for a mech such as Cyclonus was numbing his processor.

You were not so sure why other Decepticons had started sneering at you. 
Or why such young ones started crowding around you and asking about tales of survival and stories of battles since passed.
Shooing away or threatening them didn’t work, and when it did new one’s filled their place.
Little brats.

You were now practically bound to the base.
Never leaving it’s halls.
So what? You didn’t care, quite befitting a apathetic fool such as yourself.

Eventually for the first time in eons your apathy began to fade away long enough for new emotions to flow through your systems.
It had been so long since you had felt any of them that it practically hurt as eager hope and happiness pulsed through you.
Transforming had started to hurt now but you didn’t care you had to go.
NOW.

A massive battle had occurred on the other side of the known Universe.
Someone new had arose to take the Decepticon throne and in their wake Oil Slick’s corpse joined others in a gory culling of unfit Decepticons.
There was only one reason.
The journey took twice as long as it should have.
Engines struggled to put out adequate levels of force as you streaked through the stars.

It was a new gleaming citadel.
Glimmering, shining, beautiful.
Just as you remembered it.
Transforming and landing on one of the main streets, many Decepticons looked at you with a dash of confusion but mainly indifference as Cyclonus spent a few seconds stuck in a crouched position.
Landing had caused something to pop in one of your knee joints. Cold pain sensations washed over the affected area but self-repair systems did nothing in response.
The Orns spent travelling here had obviously worn down on your systems. Nothing more.
The memories of this place flooded your processor with such force Cyclonus felt as if his optics were going to melt from the building heat.
Ignoring the damage to the knee joint you power down the city streets as fast as you could with such a limp.
As you ascended through the buildings, forced to use slopes and elevators to ease the pain on your ailing joints the entire city was spread out before you.

There was a sight that made your spark clench with sharp fear.
A bright green Death crystal was in storage, it was being prepared for use in a giant cannon.
You remember that.
The crystal is was so hard to get.
Guarded by monsters and a group of aliens with their slaves.
It undoubtedly drew the attention of the Autobots who didn’t need much prompting to know for what kind of purpose the crystal was being taken for.
But if it was already so close to being ready for use then you barely had any time left.
Joints sent screaming pain notifications to your processor as you started running, alas by now what you called running was more of a hobble.

The highest room in the tower seemed to be days away at this rate.
It wasn’t guarded, there was no need. Anyone foolish to go in there with intent to kill was going to join Oil Slick.
Cyclonus wasn’t sure when his air intakes became so bad at cycling air through his systems.
Pushing through the door you fell to the floor, body way beyond tired.
“Whoa, steady on there fellow” A calming voice cooed in a concerned, friendly manner.
That voice.
That voice.
It was just as you remembered.
Nihilism melted away in an instant as tears streamed uncontrollably down your face plates.
“Oh my” The voice cooed again, a hand was held close to you.
Cyclonus was shaking as he touched the outstretched hand.
“Galvatron…” your aching vocal unit croaked as you were pulled shakily to your feet.
Taller than Megatron with a tri-pointed crest Galvatron smiled at you with sincere optics.
“Indeed, to what do I owe the honor Sir?” Galvatron smiled, his charm had helped him win so many Decepticons over when you both had appeared, along with Scourge.
“S-sir?” You gasped, no, not you, you were not worth being referred to as 'sir’ not from him. Not from your master.
Galvatron was still smiling at you. Concern across his face plates.
There were not any words in your processor that you felt adequate for this situation.
It had taken so long for you to hear of this event finally occurring, and then so long to reach here it had left you with little time.
You had not even noticed you were still holding his hand.
Tightly.
As if he would vanish at any moment.
Just being in his presence.
The presence that was everything you remember it to be.
A presence that had made you happy. Made you feel energized.
A presence that you had cared for so deeply that even your most closest of touches had not come close.
It left you speechless to be here after so long.
The tears wracked your body as it offered no resistance to the shuddering shakes that ran through it.
“Are you alright?” Galvatron helped you stand up in a sturdier position “A basic scan does show you to have damaged your knee joint?”
“I’m fine” You weakly protested “It has been so long”
Galvatron smiled and nodded, confusing you, why was he not reacting to you
“S… Sir please…” you gasped “Don’t stay here! Don’t stay!” Galvatron cocked his head
“Ah do not fear venerable Decepticon! This city is under my rule, a safe haven for us to reside in until we can conquer the rest of the Universe! And with the Crystal Cannon near completion we will have an empire to rule!” Galvatron gestured to the city below, spread out before them through a wall-sized window and balcony.
“No! Autobots!” You gasped angrily and sharply, the mention of your enemies caused Galvatron to snap round to look at you “Sir please! It’s not safe! They have a trap set up! Just leave please! Why wont you listen to me!?” You yelled desperately
“Autobots!? You know of their trap? Where? Where is it!?” Galvatron clasped your soldiers
“Just leave! Please! Why won’t you listen to me!? Am I not your second? Why?” Desperation made you bleat pathetically.
“What? My second?” Galvatron suddenly started laughing “Oh my I am sorry, your processor has clearly deteriorated with age. Cyclonus is right here! You are most certainly not him old mech!” His voice almost seemed to growl out the last part as if you 
had disrespected him. 
Sure enough Cyclonus, you, glided in through the window and bowed
“My Master” You heard your own voice croon in your smooth manner “The weapon is almost ready for your use”
He, no you, looked at you.
Your own optics staring back at you.
“Please” You gasped hoping you would listen to yourself “Leave! Save yourselves! I Beg of you! Don’t you recognize me!?” You limped forwards towards yourself, you would listen to yourself surely. “PLEASE!” It took most of your energy to yell that at yourself.
The other Cyclonus, the other you, took a step back.
“Do not mind him” Galvatron came over and wrapped his arm around the other you’s waist. Just how you remember it, firm, warm and caring “This mech has gone senile, don’t be so harsh on him, he has been living a long life and has earned the rest we can provide him in our soon-to-be empire!” He smiled.
And you smiled.
You were being smiled at by yourself.
“No please!”
“He think’s there’s a trap set by Autobots” Galvatron explained and the other you nodded as if that explained everything.
“No… no…. please don’t let it happen…. I don’t want to live this life…” Joyous tears had long since turned to tears of desperation, sorrow and sadness.
“SWEEP!” Galvatron barked and one promptly trundled into the room. A Sweep was never too far away.
“Yes my lord!” It obediently saluted.
“Take this elderly mech down to a respite chamber, I’m sure the climb up here has worn him out. Oh, and make sure a medic can see to him soon”
The Sweep bowed so far and quickly it looked as if it had bent to ninety-degrees. The soldier quickly scooped you up in it’s large wing strut and claws gently wrapped around your weeping form as it gently maneuvered you from the room.
Tears made your optics blurry but you saw Galvatron return to the other you, holding onto his hands as he did yours not so long ago.

The touches you would come to remember so longingly while cramped into a dingy Decepticon barracks with curs who didn’t even know the name 'Galvatron’.

It was doomed to happen now.

You turned to the Sweep, hoping that maybe, just maybe it could help you. It didn’t It was a lowly member of the pack and was following it’s orders.
“Leave me” You found yourself begging. It didn’t, orders were orders.
Powerless but to follow it’s lead you chanced a glance in the reflective surface of the well polished walls.

No wonder he didn’t recognise you.
Paint job, practically gone. Horns bent and crooked beyond recognition. Wing Struts crumpled and worn. Lines etched deeply into your face plates.
Oh.
You had vowed to wait an eternity for your chance at redemption.
And you had.

The Sweep placed you gently upon a resting chair.
“If It puts your processor at rest, you do have a familiar scent to you” the Sweep finally spoke.
You didn’t care and it left.
There was nothing left to do but slowly creak outside to watch the horrible event that caused your misery happen all over again.
Right on cue.
The fighting.
The Sweep swarms dismembering the first few waves of Autobot troopers before many Decepticons even got a chance at them.
The Cannon was rushed to a start up in an attempt to use it before the Autobots got it.
There was you and Galvatron fighting alongside each other, just as you remember.
Buildings fell and people from both factions whizzed past you.
You were transfixed as it all happened again.
The Space bridge the Autobots had hidden to bring most of their forces through once the attack started began activating again.
The Cannon glowed green as it powered up but Autobot charges detonated at the base and sent it toppling into the bridge.
There you were.
Screaming through the smoke and the ashes, watching yourself repeat the event that turned you into a dispirited fool for eons.
The bridge exploded and the Cannon fired.
Even viewing it from a different angle you saw only what you had seen the first time round.
You watched yourself get enveloped in the explosion and Galvatron get engulfed by a green shaft of energy from the Cannon.
While you screamed helplessly a few Sweeps quickly grabbed your arms
“Yes this one is familiar” One spoke a few others muttered something in agreement.
“Let’s pull him away before that explosion destroys us all!"You were now being flown away by a small flock of Sweeps.

Watching the smoldering remains where the few survivors still fought.
Maybe you could try to catch a glimpse of Galvatron one last time.
Maybe he survived.
The Cannon might have misfired.
But you couldn’t.
Old weary optics stained by tears and clouded by ash and smoke saw nothing but the battlefield get further and further away as you were brought along with the retreating Decepticons.
Now to live, forever knowing you failed with the one chance you had left.
