(i'm changing once again, for stat reasons. This time, i'll stick with being a venomous snake. I now naturally have a forked tongue. And I can shed my skin to look like other people. Also able to use poison to my advantage.)
X-4 sat still on the ledge of the building. He grabbed his arm, which had been shot twice, and writhed in pain. The blasted humans at the facility. They had done this to him. They were merciless creatures, and he would show no mercy on them. He began to feel woozy and shook himself out of the pain. He ignored his wound. He didn't know exactly what his next plan would be. There were so many things to do. He might just go to the facility and destroy it, along with everyone inside. That sounded like a fitting plan. But the one thing that angered 4 the most, were the fact that there were more like him. He was not the only superior being. He'd go and kill every single other experiment. They were heretics, defying the way of the natural order, and should be destroyed. He shook his head and spat his forked tongue outward, hissing. "hehehe, the foolish humans think that they can just sit idly by and be forgiven for making me like this." He smiled. "I'm going to slowly kill each and every one of them. Then he closed his hand into a fist, "but first, i'm going to kill my.....friends."
Not only was 4 a poisonous vessel, he was crazy.
