Child of my Killer

Dusttrust

Nightmare ensnared me in one of his tentacles. "simply put, i want your boy to prove he's worth something still. he will destroy an entire au on his own, or die." Nightmare didn't trust me. Of course he was going to do something like this. A portal opened as my father started to plead. "c'mon boss, please don't do this! he's just a kid!"
"would you rather i kill him now?" They went silent. Their best choice. Here goes everything. I flashed a big smile. "it's ok father. i'll be ok." Horror froze while I was dropped into the portal.

I landed with a heavy oof into a throne room. What au did he choose? Surely nothing easy. "You are here already, Sans." I looked up at Queen Toriel. She looked utterly depressed. "I've heard of what you've done in Snowdin.. how could you turn on us like this?" She summoned her fire. "Dusttrust. Of course.. sorry your majesty.. I wasn't given a choice." I rushed her, fire came at me from all sides. I weaved, dodged, and blocked, summoning a blaster. I wanted to take her out as quick as possible so I could get out of here as quick as possible. I continued on to New Home. Where was Dusttrust Sans anyway? Hotland? Waterfall? Snowdin still? I fired blasters and impaled monsters through with bones. I threw my hatchet around, a flurry of dust nearly blinding me, but I could still see. I wished I couldn't.

I worked my way through the C.O.R.E, easily tearing Napstaton NEO apart with my hatchet. The numbness was settling in again. I absolutely hate the numbness. Soon enough I was in the lab, facing off against Undyne, who shakily held a blue spear in her hands. She had so many questions. How was Sans doing this? How was their two of him? Why was he doing this? I nearly faltered. Undyne had been a great friend in my past life. But there was no going back now, if I didn't mercy her, Dusttrust would take the free LV. "I wish I had time to explain. You are a dear friend that I do not wish to kill." Relief consumed her, until.. "But I don't have a choice. You're already dead." Her eyes widened as she was impaled. If Alphys wasn't dead yet, she was going to be the hardest, other than Dusttrust himself. I've never fought my counterpart before and Ink and Dream don't count. They are Sanses, but not my counterparts.

I finished up in Hotland and started Waterfall. My murderspree continued up until I made it to the dinosaur lizard monster herself. "Hey Sans.. Where's Papyrus?" She's playing dumb. She was already aware of the going on and waiting. Shouldn't Dusttrust be here by now though? Was someone holding him back or something? I replied calmly to Alphys. "You already know where. Let's just get this overwith already.. please." Alphys grabbed her ax. I was used to axes. Still, this was Alphys I was fighting. I would need to be on high guard. "WHY WOULD YOU KILL HIM?! PAPYRUS LOVED YOU!"
"I did not." I summoned a bone to help me in blocking her attacks. "LIKE HELL YOU DIDN'T, MURDERER!!" I flinched as an ax nicked me. "You're right that I'm a murderer, but I would never kill my brother." I ducked when my soul was released from her magic. I caught the next oncoming ax and threw it back at her with precision. Not having expected this, it dug in-between her neck and shoulder. "Rest in piece, Alphys.. I'm sorry that things had to be this way.." I continued on to Snowdin.

🌑🌒🌓🌕🌔🌖🌗🌘

Snowdin was empty. Dusttrust was here, somewhere. He'd be fairly easy to find. I sniffed, sifting through the blood and dust in search of a living scent. Honey with lingering smoke. My sockets widened. I shouldn't be surprised. Of course Nightmare had thrown him in here too, as a test of my loyalty. I could just have Dusttrust kill him, than kill Dusttrust.. I followed Carrot's scent to the stations near the Ruins doors. There he was dodging Dusttrust's purple attacks. "DIE YOU IMPOSTER!"
"s-sans.. i won't hurt you.." He knew this was Dusttrust right? Not me? Stars what did I do.. did I break him, wearing my old clothes? Or did I break him the day I died? Either way, screw the plan and screw Nightmare. I wasn't watching my brother die. I darted in front of Carrot, blocking attacks. "I'm your opponent from now on, Dusttrust." Dusttrust gripped his skull. "I DON'T UNDERSTAND BROTHER, THERE'S ANOTHER IMPOSTER! WHY DOES HE LOOK LIKE ME." I lunged forward, my attack being blocked by him. I slipped behind him and tried again. He blocked again. This was going to be a long fight.

Something charged behind me. I didn't bother looking. I already knew what it was and summoned my own blaster to counter. We kept locking in battle, only to pull apart and lock again. "One crazy to another, I would've left the Papyrus 'imposter' be at least."
"I NEED ALL THE L.O.V.E I CAN GET! YOU DON'T UNDERSTAND."
"I DO! LEVEL OF VIOLENCE SUCKS! WHY CAN'T THINGS BE AS THEY USED TO?!" I shoved Dusttrust away. "Why can't I just go back to when I was Blueberry.. this life sucks.. why would anyone choose this?" Dusttrust summoned an attack, seeing this as a sign that I let my guard down. "Maybe we're all just to crazy to care. The attack came down. A blaster summoned behind Dusttrust and I rolled out of the way as it fired. I looked over to my brother, who's magic faded. "Thanks, Pap.."
