CHAPTER FOURTHTEEN: GET THE FORMULA! REMATCH WITH 621

------------------------------------------------------------------------------------------------------------

Within a blink of an eye, I was in the infirmary. Jumba made a big deal about my wounds even though I did too, but with a few bandages and stitches, I was healed.

The loss of feeling on my left arm was caused by a bone's dislocation. Jumba managed to place it back to its socket, but it was a painful experience, but I could feel it and move it again.

My wounds are slowly recovering, but Jumba said not to do whatever I did that wounded me for at least two week. I can't wait that long, I have 621 to defeat!

"I don't give a damn about the precautions; I have a job to finish!"

I tried not to mention 621 or else he'd panic and send his strongest experiments to destroy him, excluding me, they'll die.

"Sorry 0, I can't let you, your wounds were severe, a little more and it would've been the end of you."

Jumba doesn't know the situation; he would explode if he knew I released 621.

"For the last time Jumba, let me free! What good are precautions if you can't even take them on the same thing that happened?"

Jumba slammed his fist on the table in the infirmary.

"Believe me 0; I'm doing this because I care. If I didn't care I would let you die!"

True…But at least he would at least let me out of the house.

"For the last time, I don't give a damn!"

Maybe I'm being too harsh on Jumba, he's doing this because he cares about me…Or maybe he's doing this because…

"Do what you want 0. Just be careful next time."

With that, he left the infirmary, leaving me alone. I was pissed off, I was being a bastard to someone who gave me life, a home, a family, and this is how I repay him?

"Damn…"

=Third person view=

621 jumped out of nowhere unto Jumba's roof, he looked down to see a green-blue experiment walking out the door. 621's body got surrounded by the purple aurora, then he jumped down into the shadows around the area.

The green-blue experiment looked around, he heard something.

"Huh? Who's there?"

"Hmm. 613, long time no see."

The double voice spoke out of nowhere.

613, we know him as Yaarp, looked around, scared out of his mind.

"Where are you? Come on out, I won't hurt you."

The voice chuckled.

"You won't hurt me? You should worry about yourself."

613 slowly walked backwards toward a bush, not noticing a pair of red eyes stalking him.

"Please…stop it…you're scaring me."

As soon as 613 got within range, a paw came out of the bush and immediately went over 613's mouth. 613 was frozen by terror to even scream, he just stood there as a paw covered his mouth.

621 rose from the bush, and placed his other paw on 613's back.

"I think you remember me right 613?"

613 was too terrified to reply, he definitely knows what 621 is capable of.

621 chuckled.

"You're…dead!"

621 digged his paw on 613's back, breaking his spinal cord. Before 613 could even scream, 621 retracted his paw from 613's back in a blink of an eye and cut 613's throat, but not killing him instantly, 621 prefers an experiment like 613 to die a slow and painful death.

After three seconds, 613's lifeless body lies on the ground, eyes left open, blood staining the ground, 621 continued walking toward the house, grinning.

"That experiment might've been overkill, but I got better things to do."

621 said to himself as he walked toward the house.

=000's POV=

I was too harsh on Jumba, I should apologize, but where is he? I have been walking around the underground lab for a while, but still no sign of him.

I rested my back on the rocky wall of the lab. Suddenly, 619 came running out of nowhere and stopped in front of me, gasping for air.

"619? What happened?"

619 looked at me with a desperate expression on his face.

"Is 613…He's…he's…"

"He's what?"

"He's…dead!"

"What?!"

I haven't met 613, but he was an experiment. Now he's dead, I know 621 is responsible.

"Where is he?"

"C'mon, follow me!"

619 left in a hurry, so I closely followed. 619 lead me outside, and the scene lying before me made chills come down my spine.

613's throat was cut open, all of the experiments looking at the scene only stood in fear. By the pose he's lying on the ground, his spinal cord was broken. No doubt it was 621's work.

"We found him like this; we don't know who did it."

I knew who it was; I clutched my fists in anger and ran back into the house. If 621 attacked this close to home, no doubt he's in there.

=Third person view=

Experiment 523, known as Slushy, drops to the ground dead, his usual blue skin color has been repainted with red paint, blood. This time, his fore-head was the source of his bleeding.

621 walked past the body, heading to the room where Jumba kept a secret formula, 621's prime target.

[All you have to do is to drink the formula; I'll take care of the rest.]

552's demonic voice echoed in 621's mind.

"With pleasure."

621's normal voice talked.

621 opened a door, turned on the light, to reveal the formula he's been looking for.

[Perfect.]

552 expressed.

621 grabbed the formula and held it up in the air.

"With this, I shall return the evil, 552!"

621 was about to open the bottle when a gray streak zoomed past 621's arm, and the formula disappeared from 621's paw.

=000's POV=

Phew, almost didn't make it, but I managed to do it, the formula is in safe hands. Jumba was right, he was going for this.

Hm? Looks like 621 is mad now, that purple aurora is back again.

"Damn you, I didn't kill you!"

I turned to 621 and smiled.

"Like I told you, you can't kill if your heart is shrouded in darkness."

621's red eyes got thicker as he glared at me, he flexed his claws and lunged at me, but I jumped out of the way.

"C'mon 621! You're faster than that!"

Lost my mind?

Or am I taunting him?

It's a mix.

621 hissed in frustration and in anger, that sound was music to my ears. But 621 was far from giving up, he's moving his claws weirdly again. I know what that means but…what's he going to do?

"Get down!!!"

I looked behind me to see 555 jumping on me, dropping me to the floor. I looked up to see a spiral flying through the way I was standing; it could've killed me if it wasn't for 555.

"Thanks 5, a little bit later and I would've turned into a voodoo doll."

555 stood and stared at 621, who was glaring at us with the most pissed off look you can imagine. 555 glared at 621, and shed a smile.

"Long time no see…552."

552?

Did 555 lost his mind?

That's 621…

"I thought you were dead…But I was wrong, nice to see you again 555."

"Still the same psycho as always."

"I advanced."

621 chuckled, but 555 was worried. I stood up, the formula still gripped in my knuckle. Suddenly, the door behind me busted open. It was Jumba with a big plasma cannon.

"Jumba?!"

What is he planning to do with that gun? 621 can't be killed with plasma shots…can he?

"0, hand me the formula!"

It seems he knows a place to hide it. I nodded and threw it at Jumba, but 621 looked at Jumba and did his weird magic thing again, making the formula fly off to 621's direction.

I gasped as I saw that.

"Oh no you don't!"

I ran and grabbed the formula; I looked forward to see 621, readying his fist to punch me. I jumped and flew over him, landing behind him. I turned with a kick, but my kick went through him.

621 turned and grabbed my leg.

"You can't hurt me."

He lifted me up and threw me against the floor, bringing pain on my back. I looked at my paw to see the formula still grasped in my paw. I got up on my feet and jumped out of the way right before 621 could punch me.

"Turn over the formula, and I promise you a fast death."

"Yea right!"

I threw the formula at 555, he caught with ease. I ran at 621 with blinding speed, he just stood like nothing is happening.

"Fool, you can't hurt me, is your mind that damaged?"

"You might want to rethink that!"

I jumped over 621, his eyes followed me. I signaled him to turn around; he did to see multiple junk from the room flying to him, burying him in a pile of equipment and junk. My speed made enough traction to attract them, following me until it hits something.

"I figured I could hurt you with other things."

621 chuckled, and the pile of junk exploded into ashes. 621 stood there, not even a scratch, but I did make him angrier.

"0, what are you doing? Quit toying with him!" 555 and Jumba shouted at me.

"I can't hurt him, he did something to me and now I can't even make a scratch on him."

"It's true…he's worthless…But…"

621 quickly turned to 555. He gasped and threw the formula at Jumba, but 621 lunged at him. I watched as 555 struggled with 621, how can I help if I can't even hurt my enemies?

"Smell that 5? It's the smell of your death."

"I thought it was you."

621 hissed in anger and punched 555 in the face, then he kicked him on his side, sending falling to the floor.

"Ugh…621 is stronger than me…higher numbered experiments always are."

555 is hurting because of me, I let 621 out, and now I can't even hurt him. 621 picked 555 up and threw him against the wall, making a huge crack on it.

"You were always our target…"

The purple aurora around 621 suddenly got thicker, what is going on?

[No…MY target.]

That wasn't 621's voice…was that…?

"Glad to hear your voice again you coward!"

I watched as 555 coughed up blood, 621 found this amusing.

[You were always an emotionless, heartless creature 555. Now…]

621 raised his paw, pointing at 555. I saw pure electricity concentrated on the palm of his paw.

[I'll take you out of that misery, be glad I'm doing this.]

He was going to kill him; I'm not going to let that happen. 621 shot, the electric blast was slowly but quickly reaching 555. I zoomed to 555, picked him up and jumped out of the way, barely avoiding the blast.

[Damn…]

555 opened his eyes and saw me, I smiled in return. I turned to 621, he's very mad. I prepared myself, for anything he might throw at me.

"You rather fight me? Over a creature who has no heart?"

"Well…Heart or no heart, at least he still has a conscience."

"Conscience?"

"You may not hear it. But right now it's loud and clear, and it's telling me you must be destroyed!"

"Then you leave me no choice…"

He lunged at me, I couldn't avoid him. He placed his left paw on my chest, and the other one in the air, readying a fist. We both fell to the floor, 621 on me, his left paw still on my chest.

[I should've done this a long time ago!]

I held his right fist from landing a punch at my face, smoke started to rise from my chest where his left paw still remains. Even though I'm fire-proof, my chest was burning, I could feel the pain.

[Time to die!]

I continued struggling.

"Ugh…I think…I'll pass!"

I pushed 621 off of me; I got up on my feet and clutched my chest, little smoke still rises from it. The aurora surrounding 621 gets lighter, but it's still visible.

"I think that'll make things better."

621 laughed evilly. I moved my paw off my chest and saw a weird symbol burnt into my chest, it was a wave with slash marks going through it. I looked at 621 with a puzzled look.

"What did you do to me?"

621 just chuckled.

"I just…sealed your fate."

That doesn't sound good at all. But still, he added this symbol to my body, what does it mean? I rushed at 621 angry, I know it won't do anything but I threw a punch at him. Everyone gasped, 5, Jumba, even me, when I managed to land a punch at 621, but how?

"Looks like you're losing your touch!"

This was my chance. 621 took a few steps back, but I ran at him. 621 has me in a rage, he killed 613, 523, and probably many others. I released my rage on the freakin killer; I threw every punch I could throw. Hearing 621 groaning with every blow is a yell from the people he killed.

With the final punch, 621 fell to the floor, unconscious. Blood coming out of his mouth and nose, I readied my fist to kill him off, but Jumba grabbed my arm.

"Enough, he cannot be killed physically."

I looked at 621's unconscious body, how can he not be killed physically?

"I…don't understand…"

Jumba placed the formula back to where it was. The he picked 621 up and placed him on his shoulder.

"It's a survival programming I gave him, a terrible mistake I did."

I kept watching as Jumba exited the room. I turned my eyes at 621 to see some sort of ghostly figure raising its head from 621's body, its eyes glowed red, it scared me like hell.

I also noticed the weird symbol on my chest glowing when those red eyes glowed. The ghostly head dropped back into 621's body as the door closed behind Jumba.

I sighed in relief; obviously Jumba is going to place him in a more secured cage. Everything is over; my adventure with that evil experiment is over.

I snapped out of my deep thought when I felt someone's paw on my shoulder, I looked over my shoulder to see 555, smiling.

"You alright?"

I nodded.

"Yea…I'm ok."

555 walked out of the room like if nothing happened, I still can't believe how hot-headed he can be sometimes, and I guess that is how he is.

I headed to the room's exit, but I heard a sinister chuckle. I stopped and turned back, nothing.

"…It's probably nothing."

I continued walking to the room's exit.

TO BE CONTINUE…
