Jekkadian

Jekkadians are the original inhabitants of Jekkad before it was corrupted into Hell, the first lifeforms created by Davoth.

Biology
Little is known of true Jekkadian physiology, as they have not been seen without full-body armored suits. They are organic humanoids with red blood, and it is possible that they are Human-like in general appearance, like their creator, Davoth. Being naturally mortal, their bodies are unable to contain the immortal essence of a being such as Davoth, but they are able to consume Hell Energy to indefinitely extend their lifespans and prevent them from turning into demons, although it is unknown if the constant consumption of Hell Energy has any effect on their bodies, like how the Argenta Hell Priests gained grey skin and gaunt figures from their own usage of the energy. While fully sapient, their minds could be easily controlled and altered by Davoth, who had also removed any restraint from their minds to allow them to ceaselessly follow their aspirations. When faced against the Doom Slayer, they appeared to be only as strong as a Human, making them among the weakest of Hell's denizens.
