respectfully disagree
it suits him the most in the crew
he's the type to intimidate with a glance
he had done that before this coc confirmation
imo he doesnt have to this arc however
but he should learn to use/display it in some way
He's also the type that doesn't like to spend time with fodder when he has better things to do.
Now, regarding the question, if he gets to use it in this arc, I see Zoro having a CoC clash with king if he does have CoC. (It is unlikely for me because your control with CoC needs to be high enough to do said clash.)
Other option is after he gets healed, he will go after Kaido but some of the Beast Pirates won't let him go making him kinda mad using a CoC burst causing a lot of them or a good part of them to fall asleep.
