Cephalo (Resident Evil 5)

When enough damage is done to the host's body, the Plaga will suddenly mutate, and burst out from the neck. These particular Plagas seem to be the same species that inhabited the A-Type Ganados found in Europe. The Plaga body itself is weak to light, but possesses greater endurance and attack power than it did before its transformation. It can extend and retract freely to attack at long range from the hosts' neck.
