A single clash from BM and kaidou can split the sky in half, none of the supernovas can even come close to that feat. Kaidou survived the team up of 9 high tiers and is fine, big mom is on par with him and combined you would need the power of entire WG and still may not beatthem before island reaches flower capital.
They will lose in 3-5 chapters
Retainerz only lasted 7-9 chapters because Kaido was fooling around. They lasted 1 chapter vs base kaido (kaido revert back halfway 996 and wins halfway 997)
Luffy ~ inu and Neko
Kidd > denjiro
Law >~ Ashura
Zoro >~ Kawamatsu + Kinnemon
Killer ~ Kiku + Izo + Raizou
If 9 dudes can't last 2 chapters vs base Kaido then no way 5 dudes can last more than 5 chapters vs 2 Kaidos! Especially if kaido is still in base form and Linlin will actually fight.
Doesn't matter if Luffy is top tier and Kidd is inbetweener.
Base kaido can oneshot any of them , same with LInlin.
1001 : SN look good
1002 : kaido and Linlin start countering
1003 - 1004 : they KOed , end of the volume and end of the act.
