G-Type Adult

The G-Type Adult is the final evolution of the G-Type Embryo. They were created when the embryos were first spawned from William Birkin, an Umbrella virologist who injected himself with the G-Virus in order to prevent his death and also retaliate against the company who were about to take his valuable research from him.

By injecting himself with the virus he transformed into a monster named G which was hellbent on spreading the virus through parasitic G-Type Embryos. In most cases the hosts were incompatible with the virus which leads to the creation of G-Type Young.

These then mature into G-Type Adults which are creatures that exist to create more G-Type Embryos and they also have a strong fighting ability in which they attack in packs along with various G-Type Young which overwhelm and target with the aim of implanting them with an embryo.

When they die they are reduced to biomass, presumably for other G-Type creatures to consume.
