Im pretty sure the drugs got him healed til the end of the fight.
Not sure how much enma was a nerf more than a inconvinience but even if Im not remembering correctly and it was a full blown nerf to his ap and dura, what is stopping Captain Midd from taking away his swords? Kidd could push around Big Mom and with awakening he got her literally stuck, is Zoro> Big Mom an actual take yall have?
I mean, Kidd is leterally the only one the supernovas who don't have anything other than actual raw Ap in there, Luffy internal destruction, killer has the sonic thingys, Law is Law and Zoro has what the scabbards had (if i'm not mistaken that is also acoa but not sure if its internal destruction) and a blade. Even if Zoro is stronger, his haki should nor his LS should be comparable to Big Mom to null the pulling of his swords.
I know zoro had a lot of impressive showings but he still was comparable to a commander and Midd and Law had a full battle against a yonko, with Midd holding his own against her while the most idiot Strawman ever gave him head trauma the dumbest way possible.
