All three evil entities are technically the same supernatural being of darkness who is said to be the progenitor of all evil in our Omniverse. Some have said he is the personification of evil in the Omniverse. However an entity out of paranormal play, The Darkness, has that role. The Devil is a higher dimensional creature originally born directly by the hand of God as an Archangel of the light named Lucifer. His pride, and ego eventually caused him to question if his Father, God of the Omniverse, deserved to hold dominion over all things. Especially when it came to granting humans ascension to Heaven, and eventual Godhood thereby trumping the natural born Angels such as himself. They had a major falling out, and Lucifer fell from grace. He became the first fallen Angel, and he took 1/3 of God’s original children with him.
Lucifer transformed into a diabolical Arch-Demon who renamed himself Satan. Satan literally means adversary since he thinks of himself as God’s equal.
His official title is Satan The Devil: Chief Archdemon Of The Omniverse. Devil is the highest title a demon can hold, and it is held by the Emperor Of Hell. Hell being the fifth dimensional dominion of demonhood. This means that some other entity of evil could potentially hold the title of Devil. The title is honorable among demons but God chose to have its meaning be that of slanderer. Armageddon, the final battle of good vs evil, will feature Satan as a major player vying for rule of the Omniverse among others who wish to oust God from power to enact their own brand of regime change. Although as impossible as it sounds the only way to do this is by possessing the mind of God which is the very Omniverse within which we all live!
Does The Angel Lucifer Still Exist?
In the tradition of humans living out a simultaneous plethora of lives in Parallel Universes there are rumors that Archangels who fall from grace actually split into two entities. One good, and one bad. The reason for keeping this a secret would be to keep the two from interfering with each other. Plausibly recombining into one entity. Minor metaphysical evidence indicates that Lucifer still exists in Heaven but has kept an extremely low profile. The Omniverse is about playing out mathematical probabilities while maintaining balance between good, and light. Therefore it would make sense that the Archangel Lucifer might still exist. In fact there are cults who worship him, and deny the existence of the Devil.
One thing we know is that the Devil does have parallel selves in other Multiverses, aka conglomerate of related parallel Universes, he doesn’t have access to. The complex multidimensional nature of his Archangel form dictated that he be split into a wide array of Multiverses as a five dimensional being. So it’s thought that Lucifer, his good twin, would manifest in a wide array of adjacent Multiverses. This Lucifer would probably regret his decision, and see his exile as something he deserves. A chance to redeem himself in God’s eyes so he may return to Heaven someday.
He would retain rare Fallen Angel status without descending into demonhood. Eventually his good deeds would earn him the lowest Angel status. Yet his admission to Heaven would be denied until he’s deemed worthy of reentry. It’s plausible he might work to redeem Ice Demons, and help them get back their Angel status. Little else is known about this hypothetical Lucifer.
