What are these creatures that the Avengers are fighting off in the "Infinity War" trailers? Are they aligned with or controlled by Thanos?

    @Valorum definitely. Kinda getting tired of that. Just once I'd like to seem the Avengers go up against an organised army with generals and such.

    @KutuluMike how could you?! A "we don't know" answer is perfectly acceptable.

    They remind me always of Genestealers from Warhammer 40K.

There seems to be a pretty good consensus (all separate links) that they're the Outriders.

(And as @Möoz confirms in the comments, they are indeed aligned with Thanos)

The Outriders were a race of genetically engineered parasite-assassins which solely to serve their master/creator. They live binary lives, they either complete their task or they fail.

Evidence of description above

The Outriders look incredibly similar to the alien that the Black Panther is fighting, both with four arms, no eyes and fangs.

    And yes, they are aligned with Thanos

    ^ Having watched Infinity War, I can confirm that they are indeed aligned with Thanos, or at least his henchman, Proxima Midnight.
