"Wh-what are you and where are you?" I ask.

'I am the very first cyborg core in the universe and I am the most powerful core. For where I am, where else would you think, there is only the one entrance to this place.' it says.

After a while, I realize that the walls are smooth other than the runes carved into it. The floor is clear of any trapdoors. So I decided to think about the offer it gave me.

After 5 minutes, I crawled to the pedestal and when I was about to touch it, I floated up enough to see what was on it. There was a smooth, metallic sphere sitting there.

'It looks like you made your decision then?' it asks.

"I have and I will fight for those that can't defend themselves." I tell the core.

'Then get ready for there will be a bit of pain.' it says as it shoots into my chest.

"Wait Wha-" I manage to say before the pain overwhelms my body and I start to writh while floating there. It lasted for 30 minutes but it felt like hours to me. When it was done, I looked down at my body and realized that most of my body has changed. The most shocking change though was that my injuries disappeared during that transition."What the hell was that?!" I shouted.

'That was how I merge into people that I have chosen to be my host. All the others created after me was the base for your militaries cyborg.' it told me.

"Before I forget, what is your name?" I ask.

'Don't have one. It was not needed when I was created, but you could call me sparky.' Sparky said.

"Well then sparky, what can I do now that I am a cyborg" I said.

'Well, first thing is that you're not human anymore. And for your abilities, that depends on your current strength. Give me a minute to see what is available' Sparky said. 'Wait, I'm not human anymore, what does he mean?' I think to myself. 'Might as well figure out what changed then.'

After a minute, Sparky finally said what abilities I have. it was the basics: twin blades, guns(don't know what type of guns) a ship that is repairing itself after a few trillion years, etc.

'Well shall we get a move on?' Sparky asked me.

"Lets go kill some aliens" I say. After getting used to my current body by walking, running, and jogging through the tunnel, I reach the hole that I fell in.

'Well, just jump out. You have the strength for it' Sparky says.

I crouch down to jump then I launch myself through the air. I am surprised that I did jump the distance from the tunnel to the side of the tunnel without collapsing immediatly. As I get myself oriented, I notice that the area has changed. Some of the buildings have bodies on them, the area has little to none aliens patrolling, and there are many ships in the air.

'Well, are you going to attack the ground troops first, or are you going to let them kill everyone?' sparky said.

"Oh, yeah. lets kill those on the ground first then." I said. "Is there a easier way to find people and your enemies?"

"Yes, you call it radar, but this version can detect people and get their info without any trouble." Sparky explained.

"Interesting. How can I pull it up then?" I ask.

"It is already running, look around the corner of your eyesight and it should be there." He explained. When I did look, I noticed that there was something that looked like a radar but with more details. I took a closer look and saw that all of my friends were alright.

"Was there something that you were worried  about?" Sparky asks.

"Just my friends." I reply.

"I'll keep an eye out on there location and info for you then." Sparky said.

"Thanks." I reply.
