Undertale: Blue: Black and Blue

Chapter 7: The Choice

"Wow, so thi-thi-thi-this is why you're special. Alright Blue, sur-sur-sur-surprise me." Error said as we stared each other down. I flew towards him as fast as I could, and as I did his eyes widened. Before he could react I punched him in the stomach, making him lurch forward. As he recovered I brought my fist upwards, punching him in the chin. When I did he flew a few feet into the air. I flew upwards toward him and punched him in the cheek, kicked him in the side, and in the face, making him fly backwards. As he did this I flew back towards him and kicked him repeatedly while spinning, making him go slightly higher. I ended this by punching him downwards. As he hit the floor, I used the icicles my swords became and flew them downwards, impaling him to the ground. I landed onto the ground and the icicles disappeared and reappeared next to me. Slowly Error stood back up, his eyes filled with shock. "Huh, ya got fa-fa-fa-faster kid." He said. "This may be more of a challenge than I-I-I-I thought... Well, that just means I'll have to try har-har-har-harder to kill you, then." Then, he teleported behind of me and grabbed the hood of my cloak and punched me in the back. Then he kicked me into the air, grabbed me with his strings and threw me down into the ground. Pain went through my body, but in turn I felt my body get stronger than it already was. I then got up and looked at Error, who was in shock that I survived his attack. "How did you survive tha-tha-tha-that attack?!" He asked. "Well Error, it's a secret I've kept from everyone. Only my parents knew besides me. That's why I got my name, 'Blue'." I answered with a slight chuckle. "In short, let's just say...
This time it's different." After I said that he charged at me with his right fist reeled back. When he threw his punch, I grabbed it with my left hand and punched him in one of his eye sockets. He reeled back in pain, covering the eye socket with left hand. Then I used another icicle and used it to go through his shoulder. I then teleported it out and stared at him. Then, I heard a low chuckle come from Error. "Wow Blu... You need to chill out... Hehe-hehe-hehe-hehehehehe." Error said as he coughed up some blood. I looked at his health. It was at 1 HP... Should I spare him? I thought to myself as I stared at Error.

Should Blue spare Error, or should he kill Error? You decide!
