Hell Knight

Among the Demons of Hell, Hell Knights function as an elite warrior caste, boasting immense strength, authority through brutality and a surprising degree of loyalty to their superiors.

Biology
While they were initially encountered as hulking, tan-skinned satyr-like creatures, nearly identical to a breed of Baron of Hell in everything from appearance to attack power, only lacking the same level of durability, modern Hell Knights seem to resemble the Imps beneath them, albeit much larger and more muscular, with predominantly brown exoskeleton-like armor and a head resembling an exposed skull. Unlike Imps and satyr Hell Knights, skeletal Hell Knights have no ranged attack capabilities, instead channeling Argent Energy into their fists to enhance their attacks. However, another variant of skeletal Hell Knights has been able to create and throw fireballs. While they initially had eyes that were barely visible, what appears to be a more evolved strain of skeletal Hell Knights has clearly visible green eyes, and snowy white armor. While their level of sapience is unknown, the UAC have hypothesized that in addition to serving as front-line warriors and enforcers among the Demon hordes, Hell Knights also serve as gladiators. Interestingly, the Baron of Hell has been described by the UAC as the 'highest demon among the order of the Hell Knights.' Between this description and the extremely similar appearances of their original incarnations, it is implied that Hell Knights may evolve to become Barons of Hell at some point in their lives. All Hell Knights are highly resistant to various forms of weaponry.

Dread Knight
During the Demon invasion of Earth, the UAC cult attempted to enhance the Hell Knight through cybernetic augmentation. Hell Knights subjected to this process are known as Dread knights. In addition to armor plating grafted into their bodies, they also wield energy blades mounted on their arms and neural implants keep them trapped in a state of permanent rage, providing relief in the form of dopamine only during the act of killing.
