@Le:
i dont really remember but can BB's darkness power pull non-devilfruit users over as well?
It can pull anything, its only the touch to negate DFs that affect ability users. But are you talking about a specific move like Kurouzu (black whirl), instead of his overall power? We have only seen 2 battles where BB used Kurouzu - Ace and Whiteberd. So while I think it would affect anyone, there is no proof.
On the other hand, Black Hole can affect buildings and people without DF ability.
I see there is still debate on if Caeser Clown is a logia or not. We have seen him in a non-body form that looks nothing like Magellan=
