Thor Ragnarok Trailer Breakdown: 23 Things You Must See

9. All-Action Loki

Who exactly is Loki fighting for? Is this him attacking Asgard to take it back from Hela? Those cowering folk in the background appear to be terrified of him.

Or perhaps this is him trying - and failing - to hold of Hela when she first attacks? Perhaps he runs away, finds Thor and tells him about Odin's location and why they need to find him? Either way, it's good to see him fighting again, with his trusty double daggers.

There's also a shot that confirms that Hela does indeed take on the entire Asgardian defence force alone (and that seems to suggest that she can generate her "antler helmet" out of thin air)...

And some more aliens, presumably on Sakaar during the escape sequence?
