One day, the Creator injured himself at his day job. It was a minor injury, a smashed finger, which hurt like hell at first and made it difficult to manipulate tools, but it was not the type of injury that would keep him from doing his job. The Creator's employer, however, was disgusted with the fact that the Creator would be slightly less efficient the next day, ordered him to stay home. This angered the Creator, as he could not afford to miss a day of work, being on the lower end of the socio-economic scale.
And so the next day, the Creator, still angered that he would be short on funds because of the day of work missed, decided to make the best of the situation. He got up early in the morning and began to work on something that he had been envisioning for some time. He imagined a creature that was asymmetrical, where one half of its body was somewhat normal - beastly, but humanoid - and the other half, twisted and gnarled, with multiple tapered tentacles sprouting from its limbs. It was to be a beast infused with anger.
This was one of the few creatures that the Creator started and finished all in a single day. Ordinarily, the Creator would only spend a few hours at a time over a matter of weeks on a single large creature. This time, however, he had nowhere to be and nothing better to do, so he cranked up the heavy metal music and began to construct his latest wire abomination.
When he was done, the Creator's anger had ceased to be. All of that negativity had been transformed into creative energy, which flowed through the Creator's fingertips and helped him form a monster that would contain his ire. The Anger Beast, born of rage and resentment, would hold this energy until the end of time.
A millenia passed. The negative energy contained within the Anger Beast had faded, but still remained. The Creator looked down at his anger-induced brood and saw a couple things that needed to be addressed. The left hand, while satisfactory at the time of creation all those years ago, was now less than pleasing to the Creator, who had since perfected constructing hands. Surgery was required. He unraveled the old hand and replaced it with a newer, more articulate, better-looking hand - red in color, decidedly more bad-ass. He added a little color to the beast - red wire gums in the mouth, surrounding the teeth, and some rare black wire wrapped around the creature's body adding definition to the tapered tentacles on its right side.
