The Red Dragon virus has a very unknown orgin. It was said to be created by the umbrella corporation but it was actually made by James Marcus's father by using a plaga parasite and the t-virus. Little is known about the effect but it had the power to grow the hosts tounge to a great exstent and changed the colour of the hosts skin to dragon scale colour (maybe thats what the lickers where made from but the host rejected the dragon scale skin. The Umbrella Corporation created the Nyx from this virus. After the death of James Marcus's father it is rumoured that a cult took all the samples from him and injected him with a variant of the Red Dragon Virus it is said to be kept in storage underneath Sheena Island.
