FallenVerse Lucifer and Lilith :)
Lucifer turned into a vampire when he entered hell and is part bat, the snake (Zee) turns into a part of Lucifer's cane/branch, however Zee does become sentient in Lucifer's demonic form, she acts as his pet. Half of Lucifer's face is covered by a shadow because I like that stylistic choice, but the in universe reason for why is because during the Angelic War, his face was heavily scarred and essentially cracked, the scar would be visible in his human form. Lucifer and Lilith did adopt Emiko as a baby, her lore would be explained later on. Lucifer's is the king of hell and prince of pride, sinners aren't confined to just the pride ring they're sent to a specific ring depending on they're main sin. All the sins torture is in some way psychological, he puts down sinners and uses they're insecurities and regrets in life to torment them, his torture is like projecting which makes sense as Lucifer is a bit insecure of himself in terms of his physical appearance, he misses his beauty as an angel and even though he had restrictions and rules to follow, he was considered heavens prettiest angel, he essentially became what heaven views as ugly and he hates himself because of that. He does genuinely love Emiko and sees her as his own child, however he can unintentionally be over protective of Emiko.
Other facts: He's bisexual, he really likes plants, shortest sin and the only one who can't change his height. He's also the second youngest sin, youngest being Beelzebub. The pride ring is inspired by ancient Rome, mainly the Colloseum. Zee was made by Lucifer to specifically go to Eden to trick Adam and Eve, he made her from hellfire. He doesn't have wings, he has to contort his skin and bones to make bat wings, so he's in pain whenever he transforms. He does swear but he doesn't say 'bitch'.
Lilith is half lion and half Screech owl after the fall. In the FallenVerse version of the story. Adam and Lilith were made as souls not humans yet and lived in heaven, Samael (Pre fall Lucifer), who was still in the process of wanting to be on the same or more powerful than God, was attracted to Lilith and after knowing each other for a while, they had a (consentual) affair, Adam told the Seraphim and they took Adam's rib to create Eve, Lilith was angry at Samael, I mean, who wouldn't be when you were denied to go to literal paradise after sleeping with an angel for a night? She blamed Samael for this and truly believed she was being used, in complete denial of the fact she consented to sleeping with Samael while being aware of the consequences. Samael saw this and felt bad, so he offered for Lilith to join his rebelion as a spy, and she accepted the offer. She also killed a few angels during the war, and after the fall she and Lucifer's marriage wasn't the best, they both resented each other and blamed the other for what happened, but they're resentment for each other died down and fully disappeared over the years and as of present day.
Other facts: She's queer so any sexuality headcanons are welcome, She has a more neutral influence on Earth, she's mostly summoned by women who are going through rough times or stuck in abusive situations and need someone to confide in if the victim has been completely isolated from their family. Despite having mostly women worshippers, she does have men who worship her too. However she will come across women or people who are sinful or perpertrators themselves who use Lilith's abilities to be basically untouchable, this fills her with excitement as she can't wait to torture those souls and see they're faces when they meet her for real. Lilith, despite being what people call a feminist icon, and while yes that is true for the most part, she does believe in equal responsibility and that niether gender should be held to a pedestal, both genders are capable of faults respectively, and Lilith that one gender blindingly being sexist to the other without giving that gender room for discussion and nuance is insulting to her. Lilith's form of torture is more physical, essentially a predator hunting prey, she turns it into a sort of game of hide and seek, and takes a sort of twisted like joy from it. She wants her sinners to feel just as weak and helpless they're potential victims were when they were alive, watered down to a prey animal at the mercy of a person more powerful than you and being unable to do anything to fight back or get away. Pride can be a reason for a plethora of things, including murder, Lilith specifically tortures sinners who took pride in they're murders/torture, as well as sinners who saw themselves as above God or judgement.
I'll post about Lucifer's demon form at some point
