Captain Marvel Super Bowl Trailer Breakdown: 10 Things You Need To See

6. Training With Yon-Rogg

Of all the characters who have been kept secret in Captain Marvel, Jude Law's is perhaps the most closely-guarded. Fans presumed right from the off that he would play Mar-Vell, or at least a version of Mar-Vell (the original Captain Marvel in the comics), but it now looks as though he'll be Yon-Rogg, a recurring villain throughout Captain Marvel's history and a likely antagonist in the upcoming film.

Rogg looks to be the leader of the Kree's elite Starforce in the film, and can be seen sparring with Danvers in either a Kree vessel or in one of the planet's structures. They're allies, at least at that point in the film, and it seems as though each teaser has implied that Rogg is the one to indoctrinate Carol to the Kree, wiping her memory in the process.

There's no word on whether or not Mar-Vell will appear in the film (it's worth noting that Rogg repeatedly tried to kill the character in the comics), but with him, Ronan, Korath and Talos all villains too, it's fair to say the film is already juggling a fair few characters as it is.
