The first Japanese Trailer has made a new reveal unseen in the American trailers for the film: the first look at the new Cobra Commander character. Falsely reported all over the internet as a "new character" called The Doctor, we know in fact that this character is Rex aka brother of Anastasia (The Baroness) aka best friend of Channing Tatum's Duke character and finally, the character at the end of the film who takes over the evil organization and gives himself the name "Commander".

If you view the trailer below and MISS the appearance of Rex/Joseph Gordon-Levitt/The Doctor/Cobra Commander, he appears at 0:07.
