Titan G-type Edit
Created from G-virus administration in a El Gigante Plaga specimen, the mutation turned the host into a giant version of the G-creature capable of absorbing other lifeforms and gave it the ability of mass reproduction. G-type is considered a failure because of the plaga's vital parts, which are exposed when attacking.
Leviathan T-type Edit
Created from T-virus administration in a El Gigante Plaga specimen, the mutation enlarged the host's body in a few meters and slightly increased it's aggressivity, it was accepted as a failure and the project was closed.
