Considering that :
✊ Inuarashi and Nekomamushi in their Sulong form are possibly around Yonkou First Mate level
✊Izo, Denjirou, and Asura Douji could very well be around Yonkou Third Mate level
✊ Kikunojo, Kawamatsu, Kinemon and Raizo could be around Yonkou Forth mate level
Kaidou could be already fighting 9 Yonkou Commanders level
It is impressing. Which other characters could fight the 9 together ?
I don't see anyone apart from Big Mom.
