On a side note, Zoro didn't get his black blade development yet(with Enma), so either King will somehow get up(unlikely especially with the way Queen's battle ended), or it's something Oda is reserving this for later
On the other hand, there is the hakai double effect that should happen :zorothink:
There is also the nidai kitetsu, but i guess it's possible that it could simply be a replacement sword by the end of the arc, but then again if it's the case, then it makes you wonder what will happen for Zoro to replace his sword since he isn't really the type to abandon a sword just like that, especially after the flashback resolving around showing the deep relationship he has with all of them
Alternatively, the nidai kitetsu is just a troll move by Oda(unlikely lol)
