Moxxie

Moxxie is one of the main villain protagonists of "Helluva Boss", a spin-off series set in the same universe as Hazbin Hotel.

History
Moxxie is a long-suffering member of I.M.P who wants to bring some discipline and order to the company, being much more serious about actually making I.M.P work than Blitzo, he often argues with Blitzo and finds him to be infuriating due to his unprofessional nature and his tendency to stalk Moxxie day and night (to the point Blitzo has even sat and watched Moxxie sleep, asking him what he was dreaming about).

Moxxie is, however, also rather neurotic and prone to angry outbursts and stress - he also was the one who accidentally snipped a child, an event that showed I.M.P's somewhat twisted morality system as the demons worked to save the child's life only for said child to eventually go on a vulgar rampage in which he called them all out on their flaws, he called Moxxie spineless - causing Moxxie to cower in fear, though he also grew angry when the child proceeded to insult hius wife, Millie.

All of I.M.P were thus happy when they learned the child was actually their target after all and Blitzo promptly shot him, Moxxie and Millie then proceeded to beat the body and dumped it back on Earth (this was one of the few times he and Blitzo somewhat got along).

Trivia

 * Moxxie is likely a true resident of Hell, which would make him a true demon rather than a sinner (such as most of the cast of Hazbin Hotel).
 * due to being imps Moxxie, Millie and Blitzo are seen as the lowest of Hell's citizenry, which may further explain their drive for fame and wealth.
