Helluva Boss season 3 arrives on Prime Video UK this October

Helluva Boss returns to Prime Video UK on 14 October 2026, with the first part of season three bringing Blitzo, Stolas and the I.M.P. team back to screens. The adult animated comedy will follow the demon assassins as their personal lives become increasingly difficult to separate from the day job.

Blitzo and Stolas are still trying to work out where they stand with each other. Their complicated romance remains a central thread as the team continues taking assassination jobs across Earth and Hell.

For viewers following the show’s queer relationships, that leaves an important question hanging over the return. The new season puts their uncertain future alongside changes for the people working closest to Blitzo, giving the wider ensemble its own challenges to face.

What happens in Helluva Boss season 3?

Millie and Moxxie are preparing for a life-changing surprise, while Loona takes on a bigger role at I.M.P. Old enemies will also resurface as the team encounters new opportunities, putting both their working relationships and personal bonds under pressure.

The series will continue mixing violent action and outrageous comedy with character drama. Being good at killing people offers little help when the problem involves someone they care about, and the new episodes will keep those competing demands in view.

What is Helluva Boss about?

Created by Vivienne Medrano, Helluva Boss follows Immediate Murder Professionals, the assassination business run by Blitzo. Its employees take contracts in the human world while dealing with their own relationships and life in the underworld.

The show shares a fictional universe with Hazbin Hotel, but follows its own characters and workplace stories. Blitzo’s relationship with demon prince Stolas is woven into a series that combines supernatural absurdity with emotionally messy adult lives.

Brandon Rogers voices Blitzo, with Bryce Pinkham as Stolas, Richard Horvitz as Moxxie and Erica Lindbeck as Loona. The series originally built its audience on YouTube before its arrival on Prime Video.

When can UK viewers watch?

Season three, part one launches on Prime Video UK on 14 October. This is the opening part of the season, so viewers should not read the date as confirmation that the entire third season will arrive together.

The first two seasons are already available on Prime Video for anyone catching up. Those earlier episodes introduce the business, its employees and the history between Blitzo and Stolas before the next chapter begins.
