Just an unfinished concept/sketch/idea of a character from my Ascension story taking place in the Cainverse.
Adeodatus is the "Satan"-like character of my story in the manner that he is the current and original grand king of demons and all "Hell Dimensions" in which the different variations of demonic creatures make their homes. He was originally created by the Supreme God of all Evil (Aka The First Evil) when it fused its energy with a captured soul. (When the First fuses its energy into normal souls it can create demons but when it did this to an Ascended Soul it made the evil Transcendial Lilith arrancarfighter.deviantart.com… arrancarfighter.deviantart.com…
Afterwards Adeodatus began creating demons of his own in a similar manner to how he was created, his power was such that he was able to make many of the Hell Dimensions within Yyon Yoril (Yyon Yoril is a "Mini-Universe" or Mega Dimension which holds many smaller Dimensions/Worlds within it.
The Demons that he personally created were few but were all unfathomably powerful and monstrous. They became known as Demon Kings/Lords and began to populate their territories. Often these different species of Demon would wage violent wars against each other for territory and control. Adeodatus allowed this as he fed on the violence and pain of others, but those who might be foolish enough to try to challenge him and take the throne for themselves would be quickly dealt with.
Yyon Yoril is a Pocket-Universe and as such it is almost completely cut off from ours. Occasionally the boundaries between the dimensions would weaken (When the Transcendial Baskervilles ripped into our world and fused with Cain for instance) which allowed demons to come through easier.
Adeodatus and other high ranking demons are unable to enter our world but weaker entities can (I know that might not make a lot of sense that a stronger demon would have a harder time breaking through the boundaries then a weaker one, its because they don't really "Break In" rather they "Slip" in") Most of the time even weak Demons aren't able to fully enter and instead only pass a certain portion of their energy in rather then their Pseudo-Physical forms (This can result in a number of different phenomenons such as human possession or the creation of Half Demons).
As I said before Adeodatus and other high ranking demons are usually very big and monstrous rather then humanoid (though there are some exceptions).
Adeodatus himself has an appearance inspired by Megidramon from Digimon Tamers (See the smaller doodle)
Somewhat like a cross between a Lamia and a Dragon with 8 Pairs of wings (Including the pair on his forearms) and a long snake-like lower body with pairs of legs similar to a centipede ending in a blade at the tip of his tail.
While the majority of Full Demons look very similar to "Dragons" there are those who might have qualities similar to Spiders, Octopuses, Wolves, Bats, Snakes and so on.
