As a gentleman, Jonathan is kind and cheerful. Jonathan has a mindset where he tries to imagine the consequences his actions would have on other people, even if they appear to be enemies. He is gentle and sympathetic, feeling pain even as he defeats a zombified copper. Despite his skill in fighting, he will never seriously harm a person without a valid reason. Yet Jonathan can feel righteous fury at the evilness of his foes and will conduct justice by defeating them. Furthermore, he does not pity truly despicable individuals he is not familiar with, such as Doobie. With his courage and spirit, Jonathan sets a legacy as the first JoJo of the series.
