Dromos is a demon that resides in Hell. When William Kinley was sent to hell after being murdered by Eve, Dromos possessed his lifeless body in order to get Lucifer to go back to hell. When that didn't work, he had Charlie kidnapped due to the fact that Lucifer mentioned that he just got a nephew and since only a celestial could rule hell, Charlie was an option as well.
Just as he was readying the ritual; Lucifer, Amenadiel, Maze, and Chloe appear to foil the plot. Dromos refused to hand the infant over and voiced his plans of molding him into a fine ruler. He fought them and was restrained, though gloated as more demons appeared.
However, he was surprised and scared when Lucifer entered his devil form. The now enraged Lucifer ordered the demons to bow down to their king and Dromos joined them in bowing to him. Lucifer then commanded the demons to go back to Hell, as Dromos complied with his order and left Kinley's body.
Dromos desires a King of Hell and would stop at nothing to make that happen. When Lucifer refused to go back to hell, Dromos was smart enough to use Charlie due to the fact that Lucifer mentioning that he recently got a nephew. However, he retained fear of his former master, when he entered his devil form to intimidate the demons. Dromos easily complied with Lucifer's orders of bowing and going back to Hell.
