The Protagonist kicks some guy's ass

In a nutshell: The protagonist is god damn terrifying when you see him from the POV of an enemy.

>I am faced with this entity. No hesitation, and he briefly vanished into a blur for an instant. Something rushing through my chest. I didn't knew what it's supposed to be, but I will not like it. I saw the spike on his arm, dripped with something. He causes this feeling that I didn't like, so he will be struck by my appendage. I swung forward to strike, but it would not work, his arm moves upwards, stopped my blow in it's tracks. I will now question this entity. Why will he not joined me to worship the bright lights above? Why did he cause this feeling I will not like? This didn't make sense, I am supposed to knew all, being superior.
>His arm turns into a blur, and I felt an immense pressure on me as I was to move away. The feeling I felt adverse to will rip through me again, right where I just tried to struck him. I look at my appendage, only I found it emitting... Something. Was it a part of me? I cannot react before another pressure smashed me again, flat onto the surface. I saw him moving something into his body before moving downwards towards me, and then there a sound and then, darkness.

>As I stand above the corpse in front of me, having finished bursting it's head with a single attack, I wonder; Who was that? Why did they look so disgusting? What triggered a response in my instincts to kill them as soon as possible? I don't know who it was, but whoever it was, it was easy to deal with them. Almost too easy. There has to be something more to this, I just know it. As I start to head inland, maybe something will guide me to the answer I need to find.
