Hela
Because of Loki’s negligence, Hela managed to take control over Asgard. Marvel

Loki (Tom Hiddleton) isn't the main villain in “Thor: Ragnarok,” but it is because of his own doing that the goddess of death Hela (Cate Blanchett), managed to take control of Asgard.

Producer Brad Winderbaum told Screen Rant that Loki thought he was already on top of the world when he impersonated his father, Odin (Anthony Hopkins). But Odin did more than just sit on the throne, so when the threat of Hela came along, Loki was completely unprepared for it.

“[When] we left Loki, he kind of achieved his goals, he became the king of Asgard, and he is ruling that place. And what we come to learn, what Thor comes to learn early on, is that there’s a lot of terrible things in the cosmos that just shouldn’t be that way. And we learn that Odin was doing far more than it seemed on the surface to keep the universe safe,” he said. “There were all these threats that he had quelled or was keeping at bay, using his strength and power to do so, that Loki was completely unprepared for. So he becomes the King of Asgard, everything is great, it’s a good party. But he failed to realize the threats that were just over the horizon, Hela being the biggest and most terrible one of all.”

So even though Loki does not really like his half-brother Thor (Chris Hemsworth), he begrudgingly teams up with him in order to defeat Hela. “I think Loki’s a character who has always tested the limits of his power and has always tested the boundaries placed upon him. He doesn’t just stick his finger in the electrical plug socket, he burns the house down,” Hiddleston told Slash Film. “I think he has to deal with the consequences of, ‘Oh [expletive], I started something here.’ I can’t reveal what makes him rethink his perspective, but there is a big event that does that.”

Despite the mess he made, Loki might even fall in love with a new character named Valkyrie (Tessa Thompson), who, unfortunately does not trust him. “Eventually she figures out Loki’s not to be trusted. I just think there’s something about two folks that kind of come from the same place in a sense, that have the same chip on their shoulder in a way. There’s a thin line between how much they hate and love each other,” Thompson told Entertainment Weekly of Valkyrie’s relationship with Loki.

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