You Stare into the Abyss, and the Abyss stares back.

Prologue

So before we get into this thing, I just want to know why I think this story deserves to be crossed over with RWBY. I saw many similarities between many of the characters, most notably, Abyss Sans and Ruby Rose. Both of them are born from mothers of a very unique lineage, and are both born with a special destiny ahead of them, as well as each having a half-sibling. The only 2 difference between those 2 is that Abyss Sans struggles to accept his heritage and be accepted by everyone, while Ruby struggles to control her power. Also, Abyss is already more mature, while Ruby is still somewhat childish. Also, Yang will not lose her arm in the story, but will still improve. And Pyrrha and Penny will not die in the story. Alright, now that this is over, let's get right into it.

Sans P.O.V

I had hoped that I would never had to suffer this sort of fate in my place. It had become the greatest nightmare I had to endure my entire life, but not more. My name is Sans...Sans Gaster. I am a child of William Daedalus Gaster, and the younger half-brother of Papyrus Baskerville, who is 2 years older. I have no idea who my mother is. All I remember is white hair and turquoise eyes, but nothing more. I was rather unique, as I had 'scarves' in my back, that allows me to change it to whatever i desire, such as claws, swords, shields, and tendrils. Also, I have one dark-blue eye on my left eye, and a turquoise on the right. People always feared and despised me, even though I did nothing wrong. They even wished my father put an end to me, which is something that hurted me immensely. Thankfully, my father is accepting to anyone, regardless of who they are, and stood up for me and threatened to shut them up and kill them, if they try to lay a finger on me. Alphys, Undyne, they both accept me, as my greatest friends. My Dad was a scientists, who's wealth surpassed even the Schnees, and my father, unlike all the others, was accepting to Faunus. He would even defend me from people who hurt or even kill me. But when I was 9, I wasn't as lucky as before. When my dad and brother were out to work. A person came into my home and tried to kill me, and tried to use the flight of my speed to get out of here, but he caught me and tried to kill me. I was saved by a man named Taiyang. He took me home to live here. I thought I was in for something good...only to go in for something much worse than before. I was tortured and beaten for no apparent reason. I was their target practice and slave. I thought it wouldn't get much worse, until now.

Present

CRACK! POW! SNAP!

"AND DON'T YOU EVER DARE BREAK OUR STUFF AGAIN, YOU LITTLE FREAK OF A BRAT!!"

And there I go again, being the adopted middle child of the family, being blamed by 7-Year old Ruby, and 9-year old Yang for breaking a vase. I always wondered why was given such a bad fate by my own. I tried to protest that I stay until my father gets back, but they are stubborn than anything I have ever seen. They were nice for a week, until it went snap. After the beating was done, I was on the ground, broken, but healing. It has gone on for an entire 3 months. As I laid in the ground, the door opens again, and this time, my cruel sisters came into show off

Yang: "Hey, Freak, look what we've got."

I was to exhausted to turn around, and to depressed.

Ruby: "Come on, Freak! Look what we've got!"

No response. And than...

CRASH...

" SANS BROKE THE PLATE AGAIN!!"

"How could they?"

It was a bloody nightmare for me. Getting punched, kicked, cutted, and spitted at, while I am in the kitchen. I never wanted this fate. I just want to return to my real father. As they kept doing it, Summer then spoke this it to me.

"You are a gods-forsaken freak! What do you have to say for yourself.

Nothing is left for me to say. She punched and stomp, but finally took it to far. She pulled her Scythe-Rifle hybrid, and shot me in the right eye.
