\"Avengers: Doomsday\" directors Anthony Russo and Joe Russo took to Instagram to share the new teaser, writing in the caption, \"Who will you be… When you close your eyes… #FearDoom.\"

This is the third teaser for the film. It follows a previous trailer that showed the return of Chris Evans as Steve Rogers -- a character who hasn't appeared in the Marvel Cinematic Universe since 2019's \"Avengers: Endgame\" -- as well as one focused on Chris Hemsworth's Thor.

\"Avengers: Doomsday\" will arrive in theaters Dec. 18, 2026.

Disney is the parent company of ABC News and Marvel Entertainment.
