'why the hell did I grab his hand!!' I screamed in my head I look at him and noticed his scar on his right eye socket
"He what happen to your eye?" I asked and regretted asking he look at me with hate at first then he come down a bit and sighed
"Listen kiddo I wasn't like this before I......had friends before......the accident" He said and mumbled the last part
"I'm sorry what Accident?" I asked he took a deep and stop a building that said 'Grillby's' he took guys inside and set down
"so you want to know why I'm like 'THIS' Kiddo?" He asked but what creep me out was the way he said 'This' I nodded my head and turn to him

"Well it started after the Monster and Human war......

~~Flashback to the war~~

Young Sans (I'll just use Sans old name because that what it was before he got the nickname 'Killer')
After the war my father was acting different but all I know that he might did something I won't like
But any way I was heading home to my father and Pappy
"Dad? Papyrus I'm home!" I shouted and hear someone running down the stairs
"SSSAAANNNSSS!!" Papyrus screamed and hug me
"I miss you!" He said and hug me tighter
"Easy pappy you might crush my ribcage!" I said laughing and hug him back
"Hey Pappy? Where Dad?" I asked him after the hug he nodded and point down the basement I thanked him and went down stairs
"Dad? Are you here I just want to check on you" I said and open the door but what I found was purple stuff all over the floor and spot me dad on the table with some green pills in a tube
"Dad! Walk up!!" I shout and shake him but nothing happen I see the pills and noticed that had some kind of......odd wave coming off of it
I tried grabbing it but something grab my hand and pulled me down
"SaNs" my father said and open the pills and grab on out I noticed that he had some kind of purple goup (sorry I can't spell right XD) caming from him mouth he smile creeply and force my mouth open
"DoN't WoRrY sAnS tHiS wIlL oNlY hUrT a BiT" he said laughing and put the pills in my mouth and force me to swallow I started coughing and father let me go as I fell on my knees
"Why......d-did.....you........DO THAT TO ME!!" I said feeling rage in my body getting higher he just laughed and his eyes growling purple
"ReLaX sAnS sOoN yOu wIlL fElL tHe PaIn" he said as his voice getting deeper
I look up at him in rage and grab the closet thing I see.........A KNIFE I smiled creeply and feel my eyes start glowing I look into the knife and seen my eyes green (look the ones in the cover) next thing I knew before blacking out is seeing 'His' face smiling with evil and creepy enjoyment

After I woken up and I see blood on my hand I look over and see Gaster dead I didn't feel nothing about it but happyness and smile evily I got up and want upstairs I see Papyrus and pick him up
"Sans?" He question as I keep walking to the door
"SANS!!" He yelled but I didn't answer I open the door all I remember telling is....

"We're leaving and not caming back"
