Is Lady Sif (Jaimie Alexander) really a part of “Thor: Ragnarok” or not? That question has loomed all throughout the production period of Marvel’s next film, and fans were optimistic that one of Thor’s (Chris Hemsworth) closest and dearest friends would accompany him in his next journey.

But sadly, Marvel president Kevin Feige broke the news recently that Lady Sif won’t be joining Thor this time around. And the reason for this is Loki’s (Tom Hiddleston) big disguise as Odin (Anthony Hopkins).

“What has Loki been doing on that throne in guise of Odin? And we always liked the idea that he was doing a good job! He was doing a good, but shortsighted job. The trains were running on time, but he wasn’t paying attention to anything else going on in the universe or in the realms,” he told Cinema Blend. “So that was always one idea. And the idea that he would have to get rid of Heimdall, because Heimdall can see everything. That was an idea - and probably the Warriors Three, to discount them... which is probably an answer to a question I’ve been asked a few times today: Sif was probably banished. She’s off somewhere.”

Hopefully, the absence of Lady Sif would be well compensated by the appearance of two new female characters - Hela (Cate Blanchett) and Valkyrie (Tessa Thompson).

Hela is the fiercest villain Thor and his friends have ever come to face with. She’s so strong that she managed to destroy Thor’s weapon of choice, Mjölnir, during their first battle.

Blanchett earlier revealed to E! News that Hela’s impressive introduction was the very reason why she signed up to become Marvel’s first female villain. “That had me at ‘hello’ actually,” Blanchett said of her character destroying Thor’s weapon. “I thought that was really exciting that they were prepared to destroy Thor’s power in the first few minutes. It’s a nice entrance.”

As for Thompson, she told the Los Angeles Times that Valkyrie is an elite warrior from Asgard “who has sort of lost her way.” However, she will figure out her own “iconography” and sense of self once she teams up with Thor.

“Thor: Ragnarok” will be released on Nov. 3.
