I mean for you individually, not what the subjective world of One Piece would see as shocking. What would shock you the most as a reader. I'll go first then:
If Saturn's powers turn out to be the result of an awakened Zoan DF and then BlackBeard or his crew members come out of nowhere and steal it for BB, then BB will complete his long theorized 3 DF final form with a Zoan!!
That would be a massive surprise to me despite having typed this out. I would be wondering what is Oda thinking? How will that even be overcome at all?

3 DFs is theoriesed because of his Jolly Roger
