I DO NOT OWN TRANSFORMERS AND I DO NOT OWN THE LYRICS/SONG INVOLVED IN THIS SONGFIC CHAPTER

The secret side of me
I never let you see
I keep it caged but I can't control it
So stay away from me
The beast is ugly
I feel the rage and I just can't hold it

They two opposing sides faced each other down, Optimus too stunned to move and Lumina waiting to fire.

"Why do you hesitate autobot?" Megatron cackled, "Don't want to hurt your bonded?"

His evil taunting brought Prime back to the reality of the situation. Looking at the silver femme, he made note of her changed personality. The eyes are what scared him most. So dark, so dangerous, and so far from the gentle yellow he remembered. They seemed to pierce him to the core the way she glared at him with the hatred of a thousand decepticons.

"Is this even possible Ratchet?" he asked the medabot feebly.

"I'm afraid so and the worse news is that we haven't been able to find a cure for the decepticon code."

The old bot fell silent as Optimus contemplated his words. "Then we have no other choice?" the leader asked.

"No, I'm afraid not."

Making up his mind, Optimus drew his energon axe and as his face plate slipped over his mouth, he whispered, "Forgive me..."

It's scratchin on the walls
In the closet, in the halls
It comes awake and I can't control it
Hidin under the bed
In my body, in my head
Why won't somebody come and save me from this
Make it end

Finger on the trigger, Lumina rushed Optimus with a surprising burst of speed, taking the autobot by surprise. Making an arch, she struck from behind with a heavy jab to his knee joint. Optimus dodged and swung with the axe, missing her by a small margin. She turned round and charged again blaster firing and Optimus deflected every shot. Growing frustrated, Lumina dropped the gun and resorted to hand-to-hand combat, her fingers extending in a claw-like manner. With a howl of rage, she was on Prime in a nanosecond, claws ripping into his shoulder. Grunting in pain, he pulled her off and flung the femme aside.

"Ratchet, get the others and hurry. We've got to get her under control and out of here!"

The medabot took his leave and rushed to help his teammates. Looking back, Lumina was in a feral position, leaning forward with an animal-like quality, while her violet eyes flashed in warning.

I feel it deep within
It's just beneath the skin
I must confess that I feel like a monster
I hate what i've become
The nightmare's just begun
I must confess that I feel like a monster
I feel it deep within
It's just beneath the skin
I must confess that I feel like a monster
I, I feel like a monster
I, I feel like a monster

For a moment, the battle paused as Lumina took a step forward and froze in her tracks, eyes returning to amber yellow then violet. It seemed as if there was another battle taking place within her.

"Hehe, you know you want to rip his spark out, why not just do it?" a darker version of Lumina said to her in her mind.

"No, I-I can't. I l-love Optimus...ugh..." she said back.

"Yes, but what makes you so sure he loves you? If he does, why is he attacking? Explain that, little autobot," the voice cackled.

"I-I don't know! Stop it! G-get out of my head!" Lumina shouted back.

As the tirade went on, all Optimus could do was listen as his bonded fought with herself. What could he do?

"Do it! Kill Optimus Prime!" the voice commanded and wrenched back the control and Lumina's eyes returned the violet color.

She growled again, springing back into the fight, making up Prime's mind for him. Her claws connected with his axe, sparks flying. "Die! Die! Die!" she screamed, all sense of logic gone, now replaced by pure, ravenous instinct.

My secret side I keep
Hid under lock and key
I keep it caged but I can't control it
Cause if I let him out
He'll tear me up, break me down
Why won't somebody come and save me from this
Make it end

Optimus, having no choice, fought back harder and managed to land a few blows, but they were never fatal. The autobot leader grew weary as Lumina's endless barrage beat him back.

"Lumina, stop!!" he tried again and again, but never got through. It wasn't until he had her pinned to a wall did he try again. "Lumina, please listen. It's me, Optimus. I don't want to hurt you. Come back to me, please. I can't got on without you and to see you like this, it just rips me to pieces. Please!"

The trapped femme struggled, her claws creating grooves in Optimus' arms. He held tighter and forced himself to not give up. At that moment, he closed his optics and didn't want to see her like this, but Lumina had stopped moving.

Daring to look, he saw her eyes had returned to their amber color again, "Optimus..."

"Lumina, I'm here! It's gonna be ok-"

"No...l-let got! It's a trap! Optimus...I can't fight it...hurry! Get away, I can't hol-"

Suddenly, the violet color returned and erupting from her very core was a powerful sonic burst which sent Optimus keeling backwards, processor screeching in agony.

The red and blue mech pressed his servos to his head in an attempt to stop the ringing, "Aughh!!!"

I feel it deep within
It's just beneath the skin
I must confess that I feel like a monster
I hate what i've become
The nightmare's just begun
I must confess that I feel like a monster
I feel it deep within
It's just beneath the skin
I must confess that I feel like a monster
I, I feel like a monster
I, I feel like a monster

Shaking, Lumina screamed as she fought for control of her body. "Let me go!!!" she cried. "No more!"

"It's too late for that! You're a monster and you know it! Now finish it," her decepticon voiced hissed.

"No no no!!!! I won't do it!" Her entire body rocked forward in pain, clawed hand digging into the sides of her face, "Get out of my head!!!!"

Shrieking, she jerked backwards, back arched and the inner battle began. Her eyes glazed over part amber, part violet, each fighting for control.

"ENOUGH!" the dark Lumina screeched and all bodily functions ceased. "For this mutiny, you shall watch as I annihilate Optimus with your hands!"

Having no control, but aware of everything she did, Lumina staggered forward. She halted in front of her blaster.

"Pick it up..."

"No, oh no, I beg of you, please no!" she pleaded.

"Do it!"

With a trembling hand, she retrieved the blaster and began to draw near to a disoriented Optimus. When she was close enough, Prime looked up and his gaze was met by the barrel of the quivering blaster.

Its hidin in the dark
Its teeth are razor sharp
There's no escape for me
It wants my soul it wants my heart

"Lumina," Optimus whispered.

"Optimus, I'm sorry. I can't control myself, please...just run!" Lumina wept.

"You know I can't do that."

Ignoring the ringing, Prime stood and drew close, so much in fact that the blaster was all that separated them.

"Please don't do it...she'll make me shoot you and at this range..."

"I'm not going anywhere," he stated firmly and pressed the blaster to his chest. "I know you have the strength to fight this, all you need now is a push in the right direction."

"Pull the trigger! Pull it now!"

Lumina's hand shook violently as her finger drew near.

"No no no no no...stop stop stop stop!!!!" she sobbed.

Optics closed, Optimus waited, holding Lumina by the arms as she cried and begged, but the audible click was all he needed to hear as it fired.

"NO!!!!!!!!!"

No one can hear me scream
Maybe its just a dream
Or maybe its inside of me
Stop this monster

The high-pitched scream was heard by all. Autobots and Decepticons gathered into the base to see what had happened. Before their optics, sat Lumina holding Optimus in her arms.

She rocked back and forth, weeping tremendously, "No, no! What have I done?! Optimus, don't die please, I'm so sorry!"

Feeling a hand on face, she opened her eyes and he laid there gazing at her warmly, "I never blamed you..."

His voice was weak from lack of energon and the hole created by the blaster in his chest sparked from broken metal and severed wire. Deep within the puncture, a faint light pulsed slowly.

"Don't say that Optimus, oh by the allspark, please don't go!" she cried again. "Why did you do it?! Why?! You should have finished me for the monster I am!"

"I didn't because I love you and you are not a monster..."

"But-"

Optimus shushed her again. "It doesn't matter now, promise me you'll finish what we started," he muttered again.

"Optimus-"

"Promise me"

On the verge of hysteria, she nodded. Optimus smiled again and closed his optics slowly. After a while, he didn't speak or move and the servo on her face fell away slowly.

"Optimus?!" she breathed sharply.

Feeling the body grow heavy in her arms. Lowering Prime to the ground, he looked almost at peace.

Standing, Lumina emitted a slow snarl and turned to a silent Megatron, "THIS IS ALL YOUR FAULT!!!!!!!!!!!"

I feel it deep within
It's just beneath the skin
I must confess that I (feel like a monster)
I hate what i've become
The nightmare's just begun
I must confess that I feel like a monster
I feel it deep within
It's just beneath the skin
I must confess that I feel like a monster
I've gotta lose control
It's something radical
I must confess that I feel like a monster

Bent on revenge, she shouted, "Autobots, cover your audio perceptors!"

They all did in haste, knowing what was to come. Rearing back her head, Lumina bellowed out the most powerful sonic burst she had. Pained screams came from the decepticons, and one by one they fell, unconscious, all except Megatron.

"It's time to end this, you demon!"

Disappearing in a nanoclick and reappeared beside Megatron with blinding speed, claws extended. "You will suffer as I have suffered!!!!!"

Her hands dug into his armor and tore away his plasma cannon and when the decepticon leader tried to defend himself with his swords, she shattered them like glass.

"No more running, no more hiding!!! You have nowhere to go, no one to help you Megatron!"

She had her servos around him now and began to tear each parts away with as much violence as possible. Not satisfied enough with the damage she had wreaked on the decepticon, Lumina reclaimed her blaster.

"Now you will know what it feels like!"

She aimed and pulled the trigger, white hot plasma, burrowing through Megatron's shoulder and she went in a bee line for his spark, plasma buring through at each shot, getting closer and closer.

"This is what it feels like to have your spark ripped in two while watching your bonded die in your arms!!!"

She fired again and the plasma felt scorching hot as it connected.

I, I feel like a monster
I, I feel like a monster
I, I feel like a monster
I, I feel like a monster

The barrel hovered over Megatron's weak spark now. She waited while Megatron writhed in pain.

"Finish me," he wheezed voice barely audible.

"Why? So you can have the pleasure of death? I don't think so..." Lumina threw the gun aside and leaned over him. "You're going to the Elite Guard and I will personally make sure that you rust in the most cramped cell I can find."

Optics flaring in anger, she struck hard against his head, offlining the con. She had her revenge, but it didn't fill the void. "Ratchet, run a repair job on them, then cuff em."

The medabot nodded and set to work as the others scrambled about the decepticon base.

"Prowl contact the Elite Guard and tell them what's happened. Bumblebee, Bulkhead, keep an eye on the prisoners."

Going over to where Optimus rested, Lumina slid onto her knees, grief finally hitting her.

Lightrunner kneeled down and rested a servo on her friend's back, "It's what he would have wanted and you kept your promise, now he can be in peace."

"Lightrunner, why is the right thing always so hard to do?" Lumina asked.

"I don't know, I really don't know," she answered.

Wrapping her arms around her friend in a comforting embrace, Lightrunner provided Lumina for a shoulder to cry on and the silver femme wept uncontrollably, mind reveling in her grief and pain while Lightrunner gripped her tightly.
