Just thought of a plotline for hazbin homotel. 1st fallen angel, Samael.
He was banished from heaven and onto earth. He is banished from death and immortal so he keeps doing evil deeds to spite his father. He was Nero, turning Christians to candles. He was Attila, murdering all faithful. He was Vlad Dracula, raining terror on the Ottomans. He was Reinhard Heydrich, one of the architects of the holocaust. He needs has grown an addiction to devouring human flesh. Basically similar to the movie He Never Died (great film by the way).
Samael gets called by heaven to help being deceived by the heavenly council, saying he will get his peace. He works with Adam, though more ruthlessly. Samael eventually leads the charge on hell and dominates lucifer, but after finding out God (his father) is gone, he turns on adam and heaven, saying he will burn his father's precious temple to the ground. And since he's immortal, he decides he's had enough and devours adam, a horrifying sin, gaining him the attention of heaven. Samael goes berserk, devouring any soul he can come across, human, demon and angel alike. Once in heaven, he destroys god's monastery and returns to earth, kneeling down to pray. He remarks about feeling empty and wishing for an end to his punishment; immortality.
Why did I write this? Because I'm sleep-deprived and thought it was an alright plotline because as much as I dislike MANY aspects of hazbin, it isn't without fun to be had in the hands of a good writer. Now, will I make a story from it? Nope, but if someone sees this, they're more than welcome to try and make something from it.
Now if you'll excuse me, I have The Moe Order: Last Episodes of Anime waiting for me.
