Its confirmed now for Kizaru . Yonko attacks = sentomaru attacks . Only luffy toon effects were affecting him like diziness from toon forces etc . The attack in it self did nothing . Squeezing work tought but its a realy good counter for strong durability or haki . SO you probably have to get his haki to 0 before actually damaging him physically or you can cut him with haki coated swords like rayleigh did or you can squeeze him but if you are throwing blunt attacks or punches you will have a long night .
