Kei

My mind was a haze of emotions as I walked the pathway to my long overdue revenge. Normally I have no control of what I do in this form but for some reason this time was different, instead of being a mindless savage I could control myself like when I was in the spirit world. As I walked and sharpened my claws I couldn't help but feel my rage and blood lust rising to the surface at the thought of tearing Amon limb from limb with my own claws.

Soon enough the hallway opened to a circular room where Amon stood his left shoulder a stump covered bandage and his right hand resting on the hilt of a sword. Not far from him was a man I've never seen before in what appeared to be a giant suit of armor.

"Well if it isn't the monster that took my arm. I'll be sure to repay the favor before I begin my final plan." the sound of his voice brought the memory of when his men destroyed my village to the surface and with a savage howl I charged him claws extended for his chest.

Faster than I thought my claws were blocked by the broad side of his sword and with a press of a button near the hilt the blade glowed as electricity ran through it.

"A man may fear monsters but monsters it seems still fear swords."

My right hand was tingling from the shock but thanks to my new found control I could think of a plan instead of acting on instinct. As I was about to attack again a wire wrapped around my waist and pulled me back to the door just as the girls entered the room.

"I know you want revenge kid but if we do this we do this together." I gave her a nod just as a giant fist flew past her and into the wall inches beside her head.

"It seems I'll have to help Amon with his infestation problems after all."

"Dad stop! you can't want to fight us!" Asami screams as she stands in front of the group looking at her farther.

"You should have joined me when you had the chance Asami. You've sullied the Sato name by choosing this... this... monster over your own family" he said his voice dripping with venom as he swung his free arm at her.

Korra saw what was about to happen and useing all her limbs to run tacked Asami out of the way moments before the arm struck just as the chief and I charged Amon. The chief was sending her whip to keep Amon off balance while I kept to his blind side and attacked his unarmed side all while avoiding his sword strikes. But all my attacks seemed to miss their mark, in fact whenever I got close enough to land a finishing blow or even to incapacitate my hand seemed to move to the side or my entire arm would freeze up allowing him to dodge.

Asami and Korra weren't doing so hot either, the meca tank had a large arsenal of long range weapons including spike launchers on his left hand and a flame thrower on his right. Despite it only being her second transformation Korra had gotten used to running on all fours and using her claws to run vertically on walls to avoid his fire. After another failed attempt to hit I jumped back to the chief as she pulled her wires back.

"We're getting know here fast kid any ideas?"

Truthfully I didn't have the slight clue. Close range attacks weren't getting anywhere on Amon and the meca tank was to good at keeping Asami and Korra at a distance. Then I noticed one of the tanks spikes wedged into the ground near me and a plan formed in my mind. The chief smirked as she caught on as I ripped out the spike and threw it to her where she grabbed it with her wires and began swinging it to gain speed before flinging it right into the flame throwers nozzle clogging it.

Hiroshi bearly had time to react before the explosion tore most of the tanks left side to pieces giving Korra her chance. While he was raging himself Korra moved with incredible speed and broke through the opening and pulling Hiroshi out by his arm before throwing him onto the floor inches from Asami's feet.

"Asami you wouldn't hurt your farther right?" he said as Asami raised her staff.

"My farther no... but the monster he's become deserves what he gets." the impact came before he could move and soon his body sparked with electricity before his body went limb with unconscious. A few tears ran down her cheeks before she flung the staff aside and collapsed into hysteria onto the floor where Korra embraced her. Seeing the tide of the battle shifting Amon looked to one of the far walls where I assumed he had an escape hatch. Before he could get more than three steps I reached down and threw a spike with all my might into his leg the impact alone sending him into the wall.

The chief and I rushed toward him ready to end this.

"Amon as chief of police of Republic City I am placing you under arrest." she said pulling a pair of cuffs from her belt, but as she got inches from him my instincts were screaming to run or kill him now. The next thing I knew my body tensed like I was being squeezed from the inside out.

"I will commend you beast, I never thought I would have to show my true nature." without even moving the chief was thrown head first into the wall while I remained immobilized where I was.

"First I deal with you then I'll deal with the avatar." I head him say moments before a searing pain entered my chest, I couldn't look down but I knew his sword hat pierced straight through. My vision blurred and my body collapsed onto it's knees as blood entered my mouth. I might have a strong body with a good healing factor but the swords electricity was still at work and my body was doing everything it could not to go into shock or pass out.

"This moment reminds me of when I destroyed a village years ago. They put up quite the fight believing that their guardian spirit wolves would protect them but just like you they fell before me."

With a slow and painful tug he pulled his sword from my chest before raising it for a last strike. With it free my body regained the smallest amount of strength and channeling all my rage and instincts I reacted quicker then I even I thought and swiped my claws straight at his throat cleaving clean through. As darkness enveloped my mind and my body fell to the floor drained of all strength a small smile formed on my face when I realized that even If died I at least took Amon with me.
