The second interesting thing is that a member of Adonis entourage is clearly holding the WBC Championship belt, so at some point, either before the movie begins or during the film itself, Creed becomes a champion.
The second image simply shows Adonis Creed, ready for a fight.
The first is that Rocky isn’t in it, meaning that Adonis’ mentor/trainer may indeed separate from his fighter at some point in the film.
He’s dressed in his trunks and gloves and wearing a robe that implies he’s about to enter an arena for a fight.
