Tongue Demons originate in space itself. They like to live in black holes and worm holes are their major form of fast transportation. They don’t have lungs and therefore don’t need to breathe. However they do take on genders, but they can choose what gender they want. Born genderless basically. The size of a Tongue Demon is without real confinement, they tend to be as large as they want.
They feed off of pain and suffering. Eating emotions and negative auras. Usually they steer clear of any planets or life forms. Including each other. They are very solitary. They only go to the physical planet plane if they have to. Otherwise they could care less.
Tongue Demons are creatures of Red Matter and they are usually prey to the more hostile monster of Matter. Dark matter creatures keep away because of the red matter. Dark matter at this time period does not want to consume red matter like it should, spanning the universes life longer for whatever reason they have. Light matter attempts to provoke red matter but usually fails.
Tongue demons don’t really have a form or structure. The largest and strongest of tongue demons have various jaws and tongues protruding through it’s physical space. Some may grow front limbs and Others may take on hind legs. It all depends in preference.
Colors are usually deep rich tones of black and red for tongues. These ones are the most common and feed off the mental Pains of the victim. In fact any red tongue demon feeds off mental pain. Those with discoloration are special cases.
The inverted tongue demon is red with black tongues. This coloration of black tongue indicates that the demonic force feeds off the physical pain of the victim.
Discoloration of the outside, not tongue, Tongues are strictly red or black, or white. Which will be explained, indicates a mix of ability. usually taking on blue, green, purple, Golden, or brown, or any combination, just means that the demon had access to use of multiple other powers, such as void walking, use of electrical phenomenon, fire, water, even gravity.
A white tongued demon basically means that they went through a traumatic experience and one of their functions no longer works properly. For a normal black demon, this could mean that it either cannot access black or worm holes, or that it cannot feed on the proper mental plane. For a red this could mean the same, and for any discoloration this could mean the absence of a special ability.
Finally, tongue demons don’t interfere with the use of matter at all. In fact they are the only species in the entire vastness of space who are not even negatively affected by the red matter. They don’t need to use it unless absolutely necessary, such as being attacked and needing to defend themselves. Tongue demons do reproduce sexually. And once they choose a gender they are not tied to it.
