Hela (Cate Blanchett) is the main villain of "Thor: Ragnarok." It looks like the antagonist possesses a new kind of destruction that Thor (Chris Hemsworth) and Loki (Tom Hiddleston) have never seen before in their other adversaries.

Speaking to IGN, Hiddleston revealed that Thor will have plenty of questions at the beginning of the upcoming superhero movie, while Loki displays his habit of keeping secrets and deflecting queries. As expected, the stakes "are raised" in the sequel and Hela -- being the goddess of death -- brings "destruction in her wake" and a "scale of terror" that the fractured brothers have not witnessed in past years.

The actor added that the duo will be forced to work together against Hela, with The Incredible Hulk a.k.a. Bruce Banner (Mark Ruffalo) also joining in. Ruffalo told ET Online that Hela is "the worst of the worst" and the evil entity has no qualms when it comes to killing anyone who stands in her way.

Benedict Cumberbatch is reprising his role as Doctor Stephen Strange in "Thor: Ragnarok" and the character isn't exactly getting the approval of everyone -- specifically Loki. The latter isn't impressed at all by Strange's stellar defeat of Dormammu.

According to Hiddleston, Loki "dismisses" Strange's sorcery regardless of how extraordinary those abilities are. Loki has been doing magic for a century so it makes sense that he sees nothing special about the Sorcerer Supreme's powers, IGN reported.

Doctor Strange's appearance in "Thor: Ragnarok" isn't surprising, given that the end credits of his solo film showed Thor visiting him at the Sanctum Sanctorum. The God of Thunder asked for Strange's help in looking for Loki so they can return to Asgard.

There are rumors that Hela and Loki will secretly join forces in an unknown plan, Cinema Blend reported. The movie's title alludes to the apocalyptic event in the Marvel comics and the original Norse mythology, so it's possible that Hela's scheme involves destroying Asgard and the Nine Realms. Other speculations claimed that Thor will be banished by Hela from Asgard and his hammer, Mjolnir, will be destroyed in the process.

Directed by Taika Waititi, "Thor: Ragnarok" will explore the Marvel cosmic universe beyond the Nine Realms. Marvel boss Kevin Feige revealed that only three scenes are set on Earth, ComicBook reported.

"Thor: Ragnarok" bows in theaters on Nov. 3, 2017. Skurge a.k.a. The Executioner (Karl Urvban) and the Grandmaster (Jeff Goldblum) also serve as the film's antagonists. What do you think of Hela? Are you excited for Doctor Strange's cameo? Share your thoughts below!
