Hack didnt seem like a weakling and i dont think that Bartolomeo is as strong as luffy for example. What i mean by this is that he may know haki but i dont think that he could manifest it so effortlesly against Hack as NNNMIMRB said i think it would require him to atleast move his arms.

The most likely scenario is that he has a DF. I know evrything right now points to a paramecia devil fruit but i still believe that there is some sort of zoan at play. This will sound weird but maybe something like a hedhog fruit and hi shot one of his spikes at hacks hand.
