Helstrom, based on the Marvel comic book characters Daimon and Ana Helstrom, is the closest Marvel has come to horror yet, which means its release is perfectly timed for the spooky season. It also looks to be the final live-action Marvel series that isn’t an expansion of the Marvel Cinematic Universe.
The series follows a pair of estranged adult siblings, Daimon (Tom Austen) and Ana (Sydney Lemon), who happen to be the children of a demon dad that happens to also be a serial killer, and a mother who’s spent the last two decades possessed and institutionalized. As a result of their parentage, the siblings have supernatural powers and no shortage of emotional baggage.
The story kicks off when Daimon, who makes his living as an ethics professor and also happens to be a part-time exorcist, learns that the demon possessing his and Ana’s mother is attempting to carry out a mysterious sinister plot. He enlists Ana, an antiquities broker, to help figure out what’s going on. Naturally, they discover that the mystery goes far deeper–and potentially includes even more demons.
