Armadura

Armadura (from Spanish, meaning armor) is a Plaga parasite that has taken possession of a suit of plate armor from Salazar's Castle, which provides a sturdy defense. These creatures are features in Resident Evil 4.

Attacks
They attack with medieval weapons, such as broadswords and halberds. Their helmets are loosely attached, and once removed will expose a part of the inhabiting Plaga, which is extremely vulnerable to bright lights, e.g. from flashbangs.

Types
There are two varieties of the Armadura: one in a lighter-colored armor, which tends to contain a scythe-tentacle parasite, while the darker of the two will contain a centipede-type Plaga that is incredibly dangerous due to its instant-death headbite.

Additionally, some Armaduras may attempt to ambush their victims by staying still until their target approaches, at which point they attempt to hit the target with their axes, and will then invariably disintegrate from the stress of the blow, whether it be to the opponent or to the floor.
