I hope the Warden of Udon prison Babanuki willbe the one to break the taboo that SMILE fruit user are just straight up canon fodders.

Im guessing old man Hyuoguro has has devil druit and he cant use it because of the seastone cuffs. Though his physical strenght is almost gone, he might still has the power to fight once the cuffs are removed.
