DC has released a new Superman teaser ahead of the new DCU Superman movie trailer, and the footage shows the first look at David Corenswet's Man of Steel fighting a mysterious villain who wears a metal suit. The armored foe is called the Hammer of Boravia in Superman promo material, but there are theories about how he could be a more prominent character in disguise. I believe the armored villain will be working for Nicholas Hoult's Lex Luthor, with the movie pulling off a similar twist to the Superman & Lois series, revealing Ultraman is the one inside the suit.
