[Question] Which SH needs more character devolopment after the TS

[Rikud0 Sennin]

None of them have anything to do with character development nor are they issues involving it. It appears you don't really understand the concept of character development.
As for Haki, he sensed the Caribou (CoO), cut Monet (CoA) and Luffy even said he has Haki. So may I aks what you read?

He cut monet without the use of haki

 

[Hexuze]

Usopp the most and Nami if you know what I mean

 

[ziggyZ]

He cut monet without the use of haki

:sy: Why was Monet scared of him in the first place? Because when she was fodderizing Tashigi, Zoro cut her face and then she *just go back and read the damn chapter*
