Hi. I'm shadow. this is my first Au so don't judge too harshly. that being said constructive criticism is appreciated.
this is not a self insert and the first chapter doesn't explain much so stick around because the next chapter will explain much more.
Enjoy!
He stood there, hands in his pockets throwing attack after attack at the human. They dodged ducked and rolled. I was growing impatient. I told myself "Sans, hurry up." Slice, splat, death sound. They killed sans. Guess I have no choice. I jumped off a pillar. "so, you made it this far, before you go on." I said to them. "just know, you still have me to deal with!" I yelled. DETERMINATION burned around me. I summoned massive crescent blades and sliced at them. They dodged with ease and sliced at me with their knife. I teleported above them bringing straight, katana like blades down on them. It hit them slicing into their shoulder. "JUST DIE!" they screamed and slashed my arm. I looked at my heath. 15/20. "Not good!" I told myself. I sent the katana like blades flying at them. Thunk, splat. One hit them in the chest splattering all over the floor. They fell to their knees. Flash. Back to after they killed Sans. "saves, of course." I said to myself. Slice, splat, death sound. I jumped down again. They attacked me right away. I dodged "so, you have saves." Their eyes changed to pure red as they attacked again. I teleported behind them kicking them as hard as I could. They fell over and I kicked them in the face breaking their neck. No shatter. No flash. "hmm guess they weren't determined eno-" I felt the blade in my back. Shatter, flash. Of course, how could I be so stupid! We fought. Since we could both save we couldn't kill each other. We were both on the verge of passing out. They swung, I stepped back. It went on like this for, I don't know how long. It felt like days. Finally I landed a blow. Shatter, no flash, no reset. Did I break their DETERMINATION somehow? I watched them. They didn't move. I won! I ran to Asgore. He wasn't there. "wha-" I heard a noise from the room behind me. The human was getting up. I stood over them, foot poised to kick but they were crying.
