Armor Lord

Armor Lords are a direct upgrade from the typical Armor. These undead beasts are typically quite tall, with gold on their black armor, and sometimes rubies. These Armors have one special, extremely dangerous ability: To rally Armors into an army. 

These Armors are typically highly decorated and surrounded by at least 10 Armors at a time, plus the larger army. He is typically tall, strong, and a menace to deal with, alone. He can also summon around three Armors in intervals of six minutes from the ground, likely Armors already defeated.
These Armor Lords have many forms, but are typically the reflection of who they were in a past life.
Armor Lords are the remains of deceased generals or kings, even lieutenants, those who commanded on the battlefield. Typically they are good ones, such as Yyinsol, Tyronos III, or Calu. 
These are quite rare, almost legendary, but every once in a while, perhaps once in a lifetime, one appears.
