Armadura (from Spanish, meaning "Armor" - a.k.a. "Suits of Armor") are Plaga-possessed suits of armor, inhabiting the darkest corridors of The castle. They come primarily in two types, based around the overal strength of the armour - the standard "Silver" and the tougher and more ornate "Black".
They are first encountered as Ashley Graham ventures by herself in the back passages of The castle, shortly after having been released from the iron bindings trap. At first, the Armaduras appear to be harmless armors lining on the walls of various passageways. Later on, when Ashley retrieves the emblem to open the door to the upper levels, the Armaduras spring to life and attack her. Ashley must run from these enemies avoiding the stationary sets of armor as she runs from her mobile pursuers. And, to make a seemingly laughable encounter one of the scariest parts of the game, it's pitch black.
Leon is later attacked by six Armaduras guarding The King's Grail needed to open the way to the Novistador Nest Tower. However, this encounter is completely avoided if the player is playing on the Easy or Amateur difficulty setting.
