(CNN) -- After helping to save Earth in last year's "The Avengers," it seemed Thor was due for some time off.
But from the looks of the first "Thor: The Dark World" trailer, which debuted on Tuesday, the hammer-wielding Norse god has been tasked with saving the whole universe this time around.
In the second installment of Marvel's "Thor" franchise, Jane Foster (Natalie Portman) will join Chris Hemsworth's Thor in Asgard, as Malekith (Christopher Eccleston) threatens to turn the world dark.
At the end of the trailer, we see that Thor is forced to ask his brother and archenemy Loki (Tom Hiddleston) for help defeating Malekith and his Dark Elves.
"You must be truly desperate to come to me for help," Loki tells Thor from his cell.
"You should know that when you betray me, I will kill you," he replies - to which Loki asks, "When do we start?"
"Thor: The Dark World" will hit theaters on November 8.
