Demons are the chaotic creations of Syndel, the dark god and ruler of Hell. In Hell, Demons are given the job of torturing souls from Medius without mercy; it’s a job that they are said to enjoy. They are the sworn enemies of the Angels who reside in Heaven.
Demon courtship probably resembles something like this: “I’m a strong, badass mofo, and so are you. Let’s have spawn.” Not very romantic, but it gets the job done. The female Demon lays a large, slimy, semi-transparent sac (as seen in comic 291) that contains her child and hides it away in a safe place until it’s ready to hatch. Demons often do not trust each other, so it’s rare to find Demon eggs in close proximity to one another. When the egg hatches, the mother will nurse her child. However, because Demons do not need to eat (revealed in comic 65), nursing is not necessary. Then again, Demons that were not nursed as children usually end up much smaller and weaker than Demons that were. Demon children mature quickly in the first year of their life, but they do not become fully grown until their late teens.
Despite being hardy, powerful creatures, their lifespan is slightly shorter than an average Human’s. Not many demons even make it to old age, being the violent, power-hungry race that they are… One last important note: when a demon dies, it is permanent. Demons have no afterlife, and they do not just “respawn” in Hell like the souls they torture. The same can be assumed for Angels.
All Demons can make their eyes glow. The color of the glow is the same as the Demon’s eye color. This is for seeing better in the dark (although they already have very good night vision) and also for intimidation.
There are four kinds of Demons, one for each of the four magic elements in the world of this comic:
Earth Demons are HUGE. They can be anywhere from 12′ to 14′ tall. Earth Demons rely on their incredible strength to kick ass rather than magic. They’re even worse than Jakkai at using spells, but even the most basic earth spell can be devastating with an earth Demon’s physical power. These stubborn, simple-minded Demons usually don’t bother with thinking things through or making elaborate plans. While most aren’t Buwaro-level naive, they’d rather kill things and … kill some more things later. Questions just complicate matters.
Fire Demons are strong warriors second only to earth Demons in physical strength, despite their typically lanky builds. Their height range is closest to humans’. All fire Demons are fireproof and can breathe fire. Although it doesn’t actually hurt them, they really despise getting wet. Buwaro is a very poor example of what a fire Demon is typically like; Azurai is much more accurate. Fire Demons are hot-headed (hee hee), impulsive, and sadistic– they make some of the best torturers in hell.
Water Demons are an amphibious species of Demon adept at using spells. They’re the smallest in stature of all Demons, and can be as short as 5′. They are unmatched in their ability to manipulate water in all its forms (snow, ice, etc) by using magic, and are extremely fast swimmers. However, they easily get dehydrated if they’re on land without water for more than a few hours. Because they rely on water for their powers so much, water Demons are rarely if ever seen around Demons of different elements.
Wind Demons are intelligent, tall, and can fly, although their wing structures are very diverse (some wind Demons have feathered wings, some have leathery bat-like wings, some have wings separate from their arms, some have wings attached to their arms, etc). Their magical abilities are unmatched by any other species of Demon, and are especially good at using wind and lightning attacks. Wind Demons sacrifice close-quarters combat strength for their proficiency in magic. They are the most stoic of all Demons, and are very private individuals.
Despite their differences, all types of Demons are resistant to and powerful wielders of dark magic (except for earth Demons, who suck at spells anyway). Part of being a race so closely affiliated with dark power is all Demons’ innate ability to transform into kamikaze killing machines when extremely angered and/or facing certain death in a fight. In this berserker mode, all the Demon can think of is killing everything around them until they die from exhaustion. A berserk Demon with nothing to kill will destroy its surroundings and mutilate itself until it dies.
