The most potent chemical known to humankind. It was discovered in trace amounts of ALL of the people who were in cancer. 93% of who were exposed to this toxin are dead. The survivers will also die. The human body, when introduced this toxin stockpiles it in the liver, making it hard to get out of the body. Few people have the ability to excrete this substance, some genetically. Some organisms which have adapted have a strange thing called 'mitochondria' are able to break down this substance, breaking down two adenosine triphosphate molecules into adenosine diphosphate and deadly phosphoric acid.
