And some, like me, think that creatures from Thor's Norse mythos are a possibility. A possibility that some seem to ignore, even though it makes perfect sense to the evolving storyline, and could even dovetail nicely with what these rumors are saying.
"Chariots" --- odd choice of words. What image does that conjure? Gods and goddesses. Like....Thor, who rides in a chariot. And others from the Norse realms.
Small group of "aliens"....? Thor himself is an alien. The movie more than hinted that the Nine Realms are distant planets instead of different dimensions of existence, and that the races there are alien races.
Small group of name aliens....? Here's some names from Marvel for you: Ymir. Karnilla. Kurse. Hela. Mangog. Fenris. Fafnir. Amora. Skurge. Malekith. Ulik. Surtur. The Midgard Serpent.
Any number of these could be persuaded to ally with Loki. Any number of these would pose a formidable challenge not only to Thor, but to the entire team as a whole. And here's a bit of trivia: *several* of those I named already appeared in Protosevich's first draft of the Thor script, so Marvel originally intended to use them in the movies anyway.
Plus, I'll point out that the "chariot" very much has an Asgardian "look" to it --- seems like it would be right at home in Jack Kirby's/ Kenneth Branagh's vision of Odin's throne room.
I'm good with it being Kang, Kree, Skrulls, or whatever as long as it's an awesome movie... and it better be awesome.
