Hulu and Marvel are treating viewers to a visit to Hell this coming October.

According to DeadlineHelstrom will debut on the streaming service this October as part of its Huluween lineup. Other Hulu series premiering in October include Books of Blood, Bad Hair and Monsterland.

Marvel's Helstorm will focus on Daimon and Ana Helstrom, the son and daughter of "a mysterious and powerful serial killer" who "track down the terrorizing worst of humanity." In the comics, Daimon and Ana are the children of Satan and the mortal woman Victoria Wingate. However, their father was later retconned into being the demon Marduk Kurios. Daimon first appeared in Ghost Rider #1 in September 1973. Ana — also know as Satana — made her debut in October 1973's Vampire Tales #2. Due to their heritage, the two have the power to use dark magic.

Helstrom is one of the few projects left over from the Jeph Loeb era at Marvel Television and was originally planned to be a part of Marvel's "Adventure into Fear" franchise along with a TV show focused on Ghost Rider. However, Ghost Rider, and the animated adult series Howard the Duck and Tigra & Dazzler, were canceled by Hulu before they even made it to production.

With Loeb gone, Marvel centralized all film, TV and publishing projects, including Helstrom, under Kevin Feige. Unlike Loeb's era of Marvel TV, Feige plans on incorporating elements from the Marvel TV shows into the movies and vice versa. Some examples of this integration include WandaVision, which will tie into the events of Doctor Strange in the Multiverse of Madness, and She-Hulk, which is considering a Mark Ruffalo cameo.

While most of the new Marvel TV series — which also include The Falcon and the Winter Soldier, Loki, Hawkeye, Moon Knight, Mrs. Marvel and What If...? — will stream on Disney+, Helstrom will not be alone on Hulu. The majority Disney-owned streamer is still moving ahead with its animated M.O.D.O.K. series starring Patton Oswalt as the titular villain. The TV show still has no official release date.

Marvel's Helstrom stars Tom Austen Daimon Helstrom, Sydney Lemmon as Ana Helstrom, Elizabeth Marvel as Victoria Helstrom, Ariana Guerra as Gabriella Rossetti, Robert Wisdom as Caretaker, June Carryl as Louise Hastings and Alain Uy as Chris Yen. The series will debut on Hulu in October 2020.
