Since the beginning of OP a lot of emphasis has been placed upon how D's are enemy of Gods. Gorsei and the marines are the most powerful force in OP verse, not to mention one of the main purpose behind finding Roger's treasure is that the person will get to know the history of Void century which is related to WG and the weapons like Neptune and Posiedon to use against WG. The person is expected to bring justice to the world by defeating World Nobles and end their reign of terror.
With the intro of Imu Sama, we got to see that the shit is even deeper than we thought and there's actually a King behind curtain, who's pulling the strings of OP, with not even FA knowing about it.
On the other hand it looks like by the Eos, BB will be the strongest person in OP, he already has 2 strongest DFs and will probably eat another, which will make defeating him nigh impossible.... Or maybe Imu Sama is on completely another level of strength.
So, honestly can't say who the main villain will be. As a force, definently marines, but as an individual opponent for Luffy, it'll be BB.
