They usually appear as moving suits of armor. The original Armor Knight in Castlevania wielded a spear and the Axe Armor threw axes in a boomerang-like fashion. Both of these armors have appeared in many forms throughout the series and many other kinds of armors of different sizes, natures, and weapons have appeared as well.
Poltergeist or zombie?Edit
If the Knights were a type of poltergeist, then that would mean that there is nothing underneath the armor. It infers that a spirit has taken control over the suit of armor that makes up the Knight and is the cause of the animated monster. It might also explain why some suits of armor might move and others do not, and that when defeated, the armor would just fall to pieces.
However, if the Knights were a type of zombie, then that would mean that there is an undead corpse that is underneath the armor. This means that the armor itself is not enchanted, but rather being worn by a type of zombie using it to attack heroes in its path.
Some Castlevania games have stated that some armors are worn by zombies, while others are fully possessed suits of armor. The poltergeist theory would seem most appropriate since, as when defeated, most suits of armors related to Knights fall apart, revealing nothing or nobody inside them. Yet, various in-game monster descriptions claim that certain suits of armor are being worn. One theory is that the corpse is completely burned up during the death sequence before the armor collapses. It is also possible that some knights may be humans wearing the armor, such as may be the case for the Order Knight.
Knights and Axe Armors have many armored companions who will give the heroes a hard time:
These armors carry various different weapons with which to attack passing heroes. These weapons are either usual melee weapons, such as swords, spears, and maces, or projectile weapons such as a crossbow. Some are almost three times as tall as the heroes.
