The amalgam virus, having been absorbed into his skin and entered his bloodstream managed to scan his brain and identified a single pervasive thought pattern, lolis. Colin was almost constantly thinking about how cute and/or sexy the petite anime girls were. As a result, the virus modified itself and began altering its host's phisique. Colin began feeling very hot, as the virus began to burn off all of Colin's excess weight. His bones began to feel like they were being crushed as they shrunk to fit his new form. Then the pain really set in as his organs rearanged themselves in a way that was more fitting for a young lady. Eventually Colin went from a 6' tall, overweight man in his late 20s to a 4' tall girl with just a bit of baby fat that could pass for 10 or under. All told, his metamorphasis took place in under an hour. Once the pain subsided, Colin began to panic. Sure, he thought lolis were hot but he would never want to be one!
This was when the mental changes began. The virus also identified certain behavior types for beings with this body type. The first and most vital one was that they all had a female gender identity, the virus fixed this problem and suddenly Colin felt a lot more comfortable in her own skin. Beyond this uniting facent, the virus noticed that all other behaviors fit into several distinct groups.
The virus began to develop its typology. The most common variety were type A lolis. Type As were submissive to a fault, lacked many hand-eye coordination skills and often portrayed many behaviors its host labelled as "cute". Type B lolis were effectively indistinguishable from neurotypical adults, they may lack some fine motor skills but were overall capable of significantly more productivity than any other type. Finally, there were type C lolis. While they lacked the motor skills of a type B and even demonstrated many "cute" behaviors, if at a lesser rate, they differentiated themselves from type As through their increased intellegence and heavily dominant tendencies. This variety often spent most of its time ordering different groups or scheming ways to gain control. The newly mutated loli virus had to adapt the behavior of its host to reflect one of these types, and while they all had different strengths and weaknesses it ultimately chose...
