I think Denjiro Will take Care of some Cp0 members.
Oda is hiding him since ever, and is not for nothing, he is the strongest scabbard, and theres no one that he can fight on his lvl right now, even Jack is down.
I was thinking maybe he would help luffy , yamato ,momo and marco against kaido. But thats not possible animore.
The only lefts are the Cp0 members.
