They have a body made of necroflesh and bugs, and are drawn to places of suffering and emotions. The suit evolves as they go through trials and suffering, feeding on their pain and anguish. Cloak and chains are extensions of the necroplasmic body that every spawn is given for their rebirth. Eventually the suit either becomes the master or the hellspawn does.

This combined with the red skin and the horns, it can be assumed that Braveun's race is a race of demons. Based on the flashback, Bravun has had, the species is all but extinct.
The Great Shadow
The Great Shadow is the original evil that was fought by the gods: Odin, Ra and Vishnuu. Although most of this Shadow was destroyed by these gods, a part of it escaped and crashed on Earth. After causing death and destruction for a few millenia, it was threatening the kingdom of a Japanse Emperor. In an attempt to destroy it, the emperor awoke the shadow, creating Aku. Aku is a rather unique being in the universe and one of the most powerful Underlords as only one known weapon can harm him. Although his true nature remains unknown, it is believed that Aku, his daughter and a large part of his servants form a seperate species of demon.
Demongo looks similar to Aku and could be the same species as Aku, but his true origin is speculated, although they are also considered to be demons.
