MORFS: A Universe
'Massive Ontogenetic Regulation Failure Syndrome' or MORFS for short, was originally launched on the world's population by means of a genetically engineered virus. It had been started as an attempt at a biological weapon by a group of terrorists back in the early 2000s. The virus spread unnoticed across the globe. All life forms that experience some form of puberty were affected. This virus altered the strand of DNA that is supposed to protect and regulate the integrity of an individual's genome. The mutated portion essentially disables all or part of that activity, thus allowing many other mutations and gene swaps to appear and survive. This altered DNA was passed down to all subsequent generations and now each child is faced with the chance of undergoing life changing mutations in their teenage years. Some victims become human/animal hybrids. Some gain special powers. Some even change sex or become both at once. Some even get a combination, but most show little or no change.
