CP-0 should be around 500-1.5 range judging by their colleagues performances in Wano.
Lucci - 1.5
Mr Go, Kaku - 1
Maha, Stussy - 500
They can put up decent fights but Luffy, Zoro, Robin will show them levels.
Interesting how Lucci rejected the Genius tag. Perhaps he has grown a lot stronger since the burden of that tag was lifted from his shoulders after his defeat to Luffy?
