RWBY x Bioshock

The Awakening

Red Eye POV:

Dr. Sofia Lamb left me alone in the cold all for Eleanor. She once cared for us big sisters, but everything was about her once she entered the picture. I hated mother she left us to fend for ourselves and deal with this fucked up world all on our own. The splicers did whatever they wanted with no care in the world. The other big sisters just started going on a killing rampage. The only thing that hasn't changed was the big daddies wandering around with the little sisters. 

I was wandering around in the empty hallways of Rapture. Until a small group of splicers decided to try and pick a fight with me. Two stood in front of me, and three stood behind me, and before she could even do anything I slit all five of their neck in one swift motion. Killing them almost instantly, but when more showed up, some even had guns. I knew today would be boring just like all the other days after mother left. So I got ready to fight until a man stood in front of the medium-size group in front of me. 

Splicer: Look at you a big sister all alone HAHAHA.

While he was laughing I used my telekinesis and make him fly towards me and before he even knew what was happening I drove my blade threw his heart killing him instantly. When the other splicers saw this they got scared and backed away. 

Me: Anyone else want to join him?

Splicer: New leader.

Time Skip

After that day I was made the new leader of this group of splicers. But it didn't stop there I decided to take it upon myself to rebuild this place. So I hunted down every single group of splicers and made them join me and if they didn't they could become fish food. Over time I decided to make modifications to my armor and change it to better suit my needs. I was pretty smart. Smarter than any other big sister. After a few days, I made myself a new exoskeleton for me to where along with a three-headed robotic pet. 

(AU: something like that, but she wears a small breathing apparatus when she goes swimming outside. Also, remember she's almost 7 feet tall.)

With my new exoskeleton and new pet taking over Rapture wasn't hard. Soon I had all the splicers bowing to me and even majority of the big sisters even followed me. 

Time Skip

One day I was sitting in my room fine-tuning my things. When a big sister came into my room.

Big Sister: Ma'am you need to come to see this. 

Me: Alright. 

I followed the big sister for a few minutes until we were greeted by a large group of splicers that were standing around a bright light that looked like some kind of portal. 

Big sister: We don't know what this is. We thought maybe you would like to look at it.

Me: It seems to be some kind of portal. Have a few splicers and a big sister go threw and see what they can find. 

Big Sister: Yes, ma'am.

A few hours went by until the small group I sent came back and they had a lot to share with me. It turns out that I was right. This bright light was some kind of portal and it led to another world. Normally most people would be worried, but I saw an opportunity in this. Our old home was slowly falling apart and we needed more adam. Luckily I figured out how to inject people with a parisite I made that makes their body produce adam 10X faster than a little sister ever could, and I could do this to anyone. Most of the time I sent big sister out to the surface to kidnap people and we would use that as adam producers. But now we had a whole new world we could use. So I gathered up hundreds of splicers and ordered them to go into the new world and start bringing people here to be used to create adam. I even sent about a dozen new big sisters that we recently made. Over time we would take more and more from this new world and start turning it into our new home.
