big mom is away when kaido want to smack zoro and get saved by law. then again he get thunderbaguaed and need "elixir", one of the biggest plot in op, to recover.
zoro strongest attack till date doesnt even put kaido to his knee, in fact kaido scall him " rant" after get ashura'ed and proceed to send him to E.R lol
man, ppl call yamato strong because he is kaido son, even without all this yamato vs hybrid kaido chapters , ppl would think yamato is strong asf.
being strong is in her blood, after all she is WSC only daughter.
