Helluva Boss

Helluva Boss is a short cartoon from the Hazbin Hotel franchise, set to premiere on November 25, 2019 on YouTube, sometime after the Pilot for Hazbin Hotel is released. The short takes place within the same universe as Hazbin, but features a new cast of characters, a new tone, and a new story.

Plot
Follow Blitzo, a classic demon Imp who sets out to run his own small assassin business with his weapons specialist Moxxie, his bruiser Millie, and his receptionist hellhound Loona. Together they attempt to survive each other while running a startup in Hell.

Cast and characters

 * Richard Horvitz - Moxxie
 * Brandon Rogers - Blitzo
 * Erica Lindbeck - Millie/Loona
 * Brock Baker - Stolas

Trivia

 * Unlike Hazbin, Helluva Boss is recorded under SAG-AFTRA, allowing more Hollywood voice actors to be cast for the short. The casting was done by Kellen Goff who frequently visited animator Ashley Nichols' animation streams. Recording was done in ensemble at SPG Studios in Los Angeles.
 * According to Vivziepop in HAZBIN HOTEL Animation Cleanup Pt. 6 Ft. Edward Bosco, Michael Kovach, and Vivziepop, she'd be open for Richard Horvitz to voice in Hazbin, but was discouraged by it since Horvitz is SAG, which was not used in Hazbin. This was later foreshadowed for Helluva as Horvitz was acquired to voice Moxxie in the short.
 * Although Helluva still utilizes selective Hazbin animation talent, it also uses several animators who worked on Villainous, a Cartoon Network Latin America original series, most of whom became a part of the project after leaving the series due to controversial reasons. Villainous and Hazbin Hotel are often compared to one another by fans.
 * Alan Ituriel, creator of Villainous, is also aware of Hazbin but refuses to do any drawing requests featuring characters from the series due to copyright reasons with the exception of the FAN SERVICE stream due to the more loose rules of that stream.
 * Vivienne met Ituriel during her trip to Mexico and received a Black Hat drawing for her sketchbook.
 * On the Vivzie Streem #7 live stream, Vivziepop revealed that Blitzo and Angel Dust would be kicked out of Medieval Times for various shenanigans.
 * Brandon Rogers, who co-wrote and voices in the film, is also known for his Mad Tea Party video on his channel. Coincidentally, a fan of Hazbin made an animatic with selective bits from said audio and Vivienne herself commented on it; which may have been an influence for Rogers' involvement in the project.
 * According to Vivziepop in her HAZBIN HOTEL Q&A Part 2 live stream, Helluva Boss is more episodic in nature.
 * According to Vivziepop, Helluva Boss was produced faster than Hazbin as she gained enough experience producing Hazbin to not only assemble new crew but also made decisions that made production more effective.
 * According to Vivziepop, the demon that made a slight cameo in the "Inside of Every Demon is a Rainbow" music video is indeed Blitzo, whose final design was still being worked on when his cameo spot on the video was being worked on.
