Curiously this was something reserved to Zoro, even pre timeskip "Ashura" was mentioned as an strange aura by Kaku, then Kaido somehow felt CoC during Zoro's Ashura attack. Luffy, for example, doesn't have to follow this same rule. Zoro is always about intimitadion, but thats because of his edgy personality and role as a combatant, dunno if CoC has something to do with that especifically
